Warning! This page contains spoilers for The Ship of the Dead.

Blitzen, also known as Blitz, is a Norse demigod, the son of Freyja and the dwarf Bilì.



Blitzen was born to Bilì, a dwarf, and Freyja, the goddess of love, beauty and magic. He lost his father to the jaws of the wolf Fenrir when he went to ensure that Gleipnir, the rope that bound the wolf, was still working, costing him his life. Freyja, his mother, is alive but distant and calls on him mainly for favors and assignments.

He studied fashion in school, aspiring to one day open his own fashion label. When he first met Hearthstone, his fellow hero, and friend, he made the elf a custom tanning bed so that he could stay with him in the Dwarf realm of Nidavellir and not waste away, as elves need sunlight to survive.

Blitz, as well as Hearth, drank from Mimir's well of wisdom so that he could avenge his father, restore his family's honor, and realise his dream of fashion design without mockery from the other dwarves. In exchange, he had to work for the wise but unkind severed head for four years. During that time, he and Hearth were ordered to watch over Magnus Chase after his mother died. He took night shifts, since as a dwarf the sunlight petrified him, while Hearth took the day shifts.

Magnus Chase and the Gods of Asgard

The Sword of Summer

Blitz warns Magnus that two people are looking for Magnus and are passing flyers around town for him. He tells them that a middle aged-man and teenage girl are looking for him. He then tells Magnus to go see Hearth, to be careful, and then quickly disappears before Magnus can say anything back. Later Blitzen and Hearth attack Surt to protect Magnus. After a short fight, he kicks Blitzen across Longfellow bridge. When Magnus take the Black One on, he takes Randolph off the bridge.

He and Hearthstone search the nine worlds for Magnus. They find him, but he breaks his arm which Magnus heals. They are about to tell him about why they were watching him when the squirrel alarm sounds. The three flee into the hall when Magnus' hall mates offer to cover them while they go to Midgard. They wind up at Fenway where they tell Magnus that they were told he was a son of Frey and to watch him. He stays behind while Hearth and Magnus look for his sword due to sunlight petrifying him.


Mimir, his boss

Blitz meets up with Magnus and Hearth at the T stop. He has a bag which worries Hearth. When Magnus tells him the sword is not with his body and Hearth was knocked out, when they spot Sam and follow her. They follow her until they lose her and plan to go to the Charles to find the Sword. Sam then assaults them until Magnus disarms her. After a short argument, she joins them. The four travel to a dock where he throws Mimir into the water to hydrate him. He explains to them that they have until next week to find the sword and delay Ragnarök. Blitz gets worried at the mention of Fenrir. Mimir offers them knowledge in exchange for their services. They decline and he leaves. They decide to talk about it over lunch.

On their way to lunch, he hides in the shadows to avoid being petrified. When they reach the food court at the transportation building, he and Hearth grab a table and have an argument in sign language. When Magnus and Sam get back they are approached by a pigeon who threatens them with no lunch if they do not listen to him, Magnus agrees despite the others urging not to. He brings them their lunch in the form of an eagle and eats it. Sam then claims it is a giant. When it takes off with Magnus he, Sam and Hearth follow it and find him on the roof of the Boston public library. When he climbs down and tells them what he found out, they say he made a bad move but nevertheless leave to go fishing.

When they reach the docks Harald lets the demigods use his boat but not him and Hearth. When Hearth hits a bucket on his head it dents on his skull. He agrees to find shelter and meet Sam and Magnus at the library. While the demigods go fishing, he and Hearthstone do some research as to what to do next. They wait for Magnus at the public library and talk with Big Boy, the pigeon, while they wait. When he leaves Magnus suddenly appears and the three are startled but compare notes. Once they finish he is worried what this might mean. He hands the others sandwiches and sleeping bags. When Hearth falls asleep he and Magnus talk about bone steel and elf culture. He then tells Magnus they will climb Yggdrasil in the morning to get to his home world.

He, Hearth, Sam, and Magnus meet at a duckling statue in the public garden to get to Nidevllir. He says that he and Hearth had traveled too much so they needed to cool down like an engine but that Magnus could open a portal. He helps Sam and Hearth hold off the advancing Valkyries and einherjar. When Magnus opens the rift he is the first one in. When they arrive at the world tree they start to climb branches until they find a knothole leading where Sumarbrander, the sword, wants to go. Hearth then gets stuck and they are attacked by Ratatosk. He and Magnus flee into the vanishing knothole while Sam covers Hearth with her hijab, which camouflages them.


Freya, his mother

He and Magnus land in Volkswagen where the light does not petrify him. He leads Magnus to the Hall of Many Seats. Along the way they are greeted by warriors that Blitz does not care for. When they get to the boat they meet the goddess Freya, his mother. He forces himself to listen to his mother as she tells them to get her new earrings in Nidavellir. She gives them a pouch of red gold and sends them to the land of dwarves.

The two land in Nidavellir and head to Nabbi's tavern. Then they head to the counter he orders them mead and soda and asks for a meeting with Junior. After some bartering, the bartender agreed and he tells Magnus a little about dwarf history and culture. They eat nachos while they wait for Junior. When he arrives he talks bad about Blitz's father and mocks how he died. Blitz shows him the red gold at Magnus' urging and the two agree to a contest of crafting. When Junior leaves Sam and Hearth enter and he is hugged by the elf. They fill each other in on their stories and Blitz says he is no good at crafting and that Junior is the best. He then says that if he loses he will be decapitated. He takes everyone back to his apartment and makes them egg rolls. He explains the contest in more depth and tells then why Junior hates him and what happened to his father. After that, he headed to his bedroom. The next day during the contest he first makes a duck out of stress, which could triple in size. On the second round, Magnus gives Blitz the idea to make armor, as the dwarf is into fashion. During the next phase, he is aided by Magnus is making a bulletproof chain mail necktie. After making a reversible, bulletproof, chain mail vest in the third round, the judging starts. After he is declared the winner he asks for the earrings, new rope that will replace Gleipnir, and for Junior to say he was wrong and the location of the Fenris Wolf's island in exchange for the red gold. Junior gives him the first three but said he lied about visiting the island. He says that the island's location is classified but that Thor might know where it is.When Junior realizes Sam was a shapeshifter and sabotaged the contest, he and the others ran for their lives. While running he tells everyone to duck into an alley, where he is caught in a net and taken to his mother.

When he reaches his friends in Jötunheim Magnus stops Thor from killing him and Hearth helps him up. He asks Magnus about it and offers him a piece of Marvin. Blitz says that his mother made him take part in festive events but he came as soon as he could. He and Hearth share a tent for the night.

He leads the way when the four climb a cliff. When they reach a chasm across from their destination the rest and think of how to get across. Hearth summons one of Spleinir's sons to transport them across. When the four pile on the house jumps off the cliff. When the horse lands he helps Hearthstone get off and watches him while Sam and Magnus get information on Mjølnir and rescue Gunilla. He aids Magnus when he broke his leg. They meet up with Gerriod and barter for Thor's weapon. He agrees in they play catch for ten minutes. They agree and he throws hot coals at them. He carries Magnus and is blinded when embers hit his eyes. After Magnus tells Gerriod his daughters are dead, the giant throws Collins at them until the ceiling caves in and kills himself. When he recovers Gunilla holds him hostage. The Valkyrie captain releases him after everyone drops their weapons. When they send her back to Valhalla they retrieve Thor's back up weapon. The Thunder God arrives and accepts it and sends them where they need to be.

Blitzen ends up at a department store in Nidavellir and hears that Junior is being ridiculed for his poor crafting during their competition. As well as that his fashionable armor is all the rage, he says that after tonight his dream well comes true. He meets up with Hearth and the demigods at Long Wharf. He gets teary eyed when Magnus says the four of them are a team. When they meet the dwarf brothers he tells his friends that they well trey to kill, abandon and steal from them. But they get tickets regardless. On the way to Lyngvi, he is fiddling with his ascot. When they dock the dwarf brothers demand their valuables for a return trip, which he says they well not come back for them. Magnus says that they do not need a return trip and the brothers leave. The for then go to face the wolf.

When they find Fenrir, Blitzen begins taunting them. He says that his father's bones are around heard somewhere. He is about to charge the wolf but Sam and Magnus hold him back. He is snapped out of it by Hearthstone. Gunilla arrives with two other Valkeryies and Magnus' hall mates. When Gunilla order their arrest Magnus' hall mates refused to do so. When Surt and his fire giants arrive wearing chain mail suits he says they stole his designs. He charges at one of the fire giants and impales him with his harpoon. He then attacks the wolf head on but has his throat slit. Hearth casts a protection spell to keep him safe. Magnus sees his ascot change from silk to chain mail, which saves his life, he is helped to Magnus and Sam by Hearthstone. When the island starts to fade he and the others rush to the shore. When T.J. pulls out a Frey Boat he and everyone else gets aboard. He and Hearth have an argument in Alf sign language about who has a dumber plan, but wind up having a poking contest instead. When Magnus tries to heal Halfborn, Blitzen arns him that the strain might be too much for him.

When they arrive at the hotel he and the others are escorted to the feast hall where the thanes call him, Hearth and Sam Magnus' questionable companions. Before judgment can be passed, X reveals himself to be Odin. Once the All-Father tells what he has been doing the last two years he rewards Magnus and his friends. He releases Blitzen of his services to Mimir and offers to help him open up his shop. Odin even allows an endorsement deal, much to the dwarves joy. Odin gives him full access to all of the Nine Worlds.

Blitzen attends the funeral held for the fallen Valkyries at the public garden. He says that he is planning to have his shop located on Becon Street.

The Hammer of Thor

Blitzen has not seen Magnus since the funeral for the fallen Valkryies. His shop, Blitzen's Best, was abandoned. He and Hearthstone were seen in a dream where Mimir told him and Hearth to go on a mission. However, Hearthstone was concerned because he predicted the dwarf would die on this mission, but he agreed to go anyway. He and Hearthstone met up with Magnus and Sam in Provincetown to retrieve Mjølnir. Despite the possibility that he might die, he goes on this mission to help his friends. He senses the wight's tomb and has Hearthstone open it, the four then fall into the tomb. After finding an iron coffin that says blood river, he gets a little uneasy. After Gillir orders his bodyguards to attack them, he stalls them by having them talk about their weapon's history, which works for a little while. After they defeat the draugr, he feels that this was a trap. Almost immediately Loki and Randolph Chase appear before them. He helps Hearthstone up and calls Loki crazy for unsheathing Skofnung. He is stabbed in the gut by Randolph on Loki's orders. Hearthstone cradles his friend while Magnus tries to heal him. In the end, Magnus petrified him in order to stall until they find the Skofnung stone.

His friends take his petrified form with them, hoping he does not start to crumble. Hearth summons bubble wrap and tape to ensure he stays safe. As Magnus and Hearth are about to jump off the plane, the elf straps the two of them together with his scarf. After Magnus and Hearthstone are brought to Alderman by the police, he is placed in the trunk. Hearth's father tells then that to cure him, the dwarf must be put in running water. He is left behind while Hearth and Magnus find Andvari's treasure. After they succeed they unpetrify him and use the Skofnung stone to heal his wound. Hearthstone and Magnus fill him in and he shows his concern now that Alderman his the ring. At the party, he looks concerned while looking at Aldetman and surprised when Inge kisses Hearthstone. He flees with his friends and fled to another world when Jack opened a portal. They land in a stairwell and he takes the Snoknung stone from Magnus. He and Hearth agree to meet up with Magnus the next day. Before he and Hearth depart for Nidavillir.

The next day he, Sam, Hearth and Stanley wait for Magnus and Alex at the park. He, Alex and Magnus ride Stanley to Jötunheimr. They are knocked off the horse by a tree branch when the arrive. After being pointed in the right direction by a jotunn named Tiny, he tells them to bring his bowling bag to Utgard-Loki's bowling ally to show that they are friends. The giant leaves and he find the bowling bag. He inspects the bag and learns that it is not finished, that it is unnamed. Blitzed feels that if he can finish it with magic, they can carry it. However, he requests Magnus' hair and Alex's blood, much to their shock. The demigods reluctantly agree.

He and Jack spend the next day and night working on the bag. After twenty four hours he finishes the bag and demonstrates it before passing out from exhaustion. The three hike up to Utgard Lines where they find Utgard-Loki, who is holding Sam and Hearth. Utgard-Loki releases their companions and tells them that to get the information that they want, they must compeat in contests to prove their worth or die trying. They talk strategy until Utgard-Loki shows up and tells them that an alliance between Loki and Thrym would put an end to his reign as king. After Sam decuces that her opponent is fear itself and Hearth destroys his opponent in pinball, be manages to make a giant good looking after sleeping under a counter for forty years. After Alex and Magnus tie their challenge, the giant king tells them Loki plains to use the wedding to get the sword and Stone to free himself. Utgard-Loki tells them that the young have to options, to die at this moment or find the hammer themselves. Soon afterward the giants give chase.

As the giants gain on them, they are saved by the goddess Sif and brought to her house, which he finds marvelous. He is also intrigued by Sif's ability to control her hair. As they go to meet with Thor he says Sif is not all bad. When they tell the thunder god about the hammer, Alex surprises him by volunteering to take Sam's place as bride. He is shocked by this but thinks it is the best option. Thor gives him and Hearth a pass that will allow them to go to Valhalla to recruit einharjar. 

Just as Magnus and co are about to lose, he, Hearth, T.J., Mallory, and Halfborn arrive and fight the giants. He tells Magnus that the gods will be hear soon and he proceeds to punch Thrym in the face. While they are destracted Loki is freed. He watches as Loki kills the serpent and is treated for injuries when the gods arrive.

Back at Valhalla, he is to distracted by Loki's escape to enjoy the feast. Helgi then invites him and his friends to his office and tasks them with capturing and rebinding Loki, which can delay Ragnorok. He and Hearth spend the night in Magnus' suite. He and Hearth plan to head to his shop to strategize for their quest. He reassures his friend that Loki's escape is not his fault. He is gone by morning.

The Ship of the Dead

He and Hearth were waiting to be picked up when they were attacked by a sea serpent who, unknown to them, was really the pet of the Nine Billow Maidens. They are held captive by Aegir, who plans to eat them. But are freed and invited to dinner when Sam says she must break fast with a dwarf and an elf. During the standoff they manage to calm Aegir down and convince him to let them leave if they can escape his daughters. During the fight he insults the billow maiden's fashion sense and through plates at them. He escapes along with the rest of the crew when Njord arrives and Hearth blasts a wall.

When they surface he, Magnus and Hearth speak with Njord at the Vanir's request. He is uneasy around the god because his father's torn clothing was found on the shores of Nidavellir. Njord tells them to go to Skadi's harbor, as it is the safest route, and to get Kvasir's mead. However Njord says he and Hearth might die. The god says they must look for Bolverk's whetstone. He and Hearth agree after conversion about the location and let Magnus join them when they are ready. They say their goodbyes and Njord sends them away.

He and Hearthstone have spent the last few days scouting out Alderman's mansion and arrive on the Big Banana to tell Magnus they need his help in Alfheim with Alderman. They venture deep onto the property and find a cave they think Alderman is in. Alderman emerges momentarily in the form of a dragon. Blitz tries to consult his friend, but Hearth says the only way to help him is to kill him. He is concerned that the act will taint Hearthstone's wyrd so he backs Magnus' plan to kill the cursed dragon. He helps Magnus practice getting out before the cursed blood floods the tunnel. When Alderman moves in to attack Hearth he comes to his friend' defense. After Alderman dies he speaks with Hearth and helps Magnus with Andvari's treasure. He put the cursed ring, still on Alderman's severed toe, into the bag. He and Magnus bring the bag back to the river and walk back to Hearth to see him roasting the heart. He continues to consult Hearth and is shocked when Magnus accidentally destroys the heart and ingests the blood. He tells him it would affect his DNA. The four head back to the Big Banana.

They return and tell the crew their story. He and Hearth go below deck to sleep and are left to rest when everyone goes in search of a train station. He and Hearth sleep through the giant attack and are glad to see Magnus safe when he returned. When the big banana reaches Jotunheim he wakes Magnus.

The ship gets caught in the ice and they decide to walk to shore. He holds up Hearths along the way and offers to dig a cave to keep them warm. Skadi shows up and invites them in to explain themselves. They bath and have a hot meal with the giantess. She tells them Naglfar will launch by midday the following day. She gives them permission to spend the night. Magnus wakes him up and they have breakfast before skiing over to Naglfar.


His expandable ducks

When they arrive he goes with Hearth, T.J., Mallory and Halfborn to destract the forces of the dishonorable dead while Sam and Alex help Magnus flyt Loki. He throws expandable metal ducks at the enemy. After Loki grudgingly accepts the flyting he props up Hearthstone and watches the contest and is concerned Magnus will lose. He is please with Magnus's complement about him besting Eitri Junior, sewing that bowling bag for Tiny, berating Alderman, and making patented stainless-steel neckties and expand-o-ducks. He rides on Hearth's shoulders as they escape the hoards. They jump of the ship at Sam's request and land on the backs of water horses. They escape just as the harbor freezes over.

They spend three days at sea. During this time he and Hearth make sure everyone is alright and he teaches Alex how to make chain mail clothing. When Magnus asks to speak with the child of Loki, Blitz leaves. The big banana takes them to Vigridr, where the einharjar will die during Ragnorok, and are greeted by the gods. He is embraced by his mother and goes to the feasting tent with the others. Odin gives him, Hearth and Sam signed copies of his newest autobiography. Before they head back to Valhalla they hand over Loki. When they return to the hotel he and Hearth are made honorary einharar, and they are able to come and go from the hotel as they please. The two leave and angree to meet with Magnus about his reward from the gods.

He and Hearth help Magnus out at the Chase Space, the youth shelter he turned his ancestral home into. They work ad cooks and he allows some of the kids at the shelter to work at his shop. He cooks food and watches fireworks with everyone on the roof during the Fourth of July.

His face is the color of saddle leather with flecks of snow and looks like he is permanently alarmed. His nose has been broken so many time it looks like a lightning bolt. He is about five feet and five inches tall and wears a snow caked trench coat.

After pretending to be a homeless man, however, Blitzen wears colorful and stylish clothes. However, he is often anxious to cover his skin during the day, as he gets petrified in direct sunlight.[1]
