Don't lose hope, Frank. Rainbows always stand for hope.

–Iris to Frank, in The Son of Neptune

Iris is the Greek Goddess of the Rainbow.

She delivers Iris Messages for gods and, if asked nicely and she is not too busy, for demigods as well.

It was possible that she was neutral in the Second Titan War because she was too busy carrying messages, for she was not listed among the many minor deities who had switched over to Kronos' side.

Her Roman counterpart is Arcus.


Iris is the daughter of Thaumas, one of the minor sea gods, and the Oceanid Electra. Her sisters are the Harpies, Aello, and Ocypete. She also has a twin sister, Arke, who served as messenger for the Titans in the first war, and was thrown into Tartarus with her masters by Zeus after ripping her wings off.

As the sun unites heaven and earth, Iris links the gods to humanity. She travels with the speed of wind from one end of the world to the other, and into the depths of the sea and Underworld. She is married to Zephyros, the God of the West Wind, and their son is Pothos.

Iris also wields a pitcher of water originating from the River Styx, and uses it to put the person who still lies despite promising to tell the truth to sleep. She was said to bear golden wings of a butterfly.

Due to her status as the Goddess of the Rainbow, Iris was commonly underestimated, but her children are, in the case of Butch, still rather powerful.

Percy Jackson and the Olympians

Throughout the series, Iris' services are called upon (by throwing a drachma into a mist) so that the characters may communicate with each other.

The Sea of Monsters

Iris is mentioned to be on good terms with Hermes, as they are both messenger gods, and always helps the demigods in moments of peril. Chiron mentions that he and Iris have been friends for centuries and that he asked her to notify him if anything strange happens in the Miami area.

The Last Olympian

A cabin is built for her demigod offspring at Camp Half-Blood, due to Percy's request to give the minor gods their own cabins instead of their children being crammed into the Hermes' Cabin.

The Heroes of Olympus

The Lost Hero

Iris is the mother of Butch in the series. Even though Zeus forbade the gods to interact with the surface, Iris still sends Iris Messages for the demigods; making an exception for her as a messenger. The demigods also use her to contact their allies.

The Son of Neptune

Iris is first shown when a huge rainbow appears before the army of monsters, led by the giant Polybotes approaching San Francisco. They attack the light, but it burns their bodies, and melts the weapons into rainbow colors. She then throws a gluten-free, no-sugar-added, vitamin-enriched, soy-free, goat-milk-and-seaweed-based cupcake simulation (which the monsters first assume is a grenade and which both parties assume is a Ding Dong) at the horde when they demand food. She says that she has eased up on her duties as messenger of the gods and has opened a chain of stores called Rainbow Organic Foods & Lifestyles (R.O.F.L). The stores are described as having "bins of nuts and dried fruit, baskets of apples, and clothing racks with tie-dyed shirts and gauzy Tinker-Bell-type dresses." The entire store is adorned with wind chimes, crystals, geodes, dream catchers, macramé, and other "strange stuff." Iris tells her employee Fleecy (who she now has handle Iris-Messaging) to give an ailing Percy "green tea with organic honey and wheat germ" for his memory sickness. Hazel goes with them so that Iris could have a private talk with Frank.

She encourages Frank to reject the quest and his destiny, live without the gods, while showing him visions of his past to try to explain his gift. She also offers to hire him, but he declines. She prompts him to seek Phineas and ask him for help, but not to kill her sisters, the harpies. She also instructs him to use his spear to kill the basilisks. Her last words of advice come with a prophecy - he will die holding his piece of tinder, but he will live longer if he gives it to someone he cares for. She gives Percy Jackson a tie-dyed "masculine accessory bag" (a purse) that she states looks "good" on him before they leave to continue their quest.


Iris is a free spirit. She is a strictly non-violent goddess who only attacks in self-defense. She is also upset that living a life for others (by delivering messages for others) has left her with no identity, as there are no shrines to her or a sacred animal. Because of this, she opened up her own store and is doing what she wants to do, like giving advice to Frank.


Iris has olive-colored skin, long black hair and warm brown eyes. She appeared as a middle aged woman with glasses to Frank, Hazel, and Percy. She reminds Frank of his mother by the way she smiles, with one side of her mouth, her warm brown eyes and the way she tilts her head like she's considering a question.


Arcus is Iris' Roman counterpart. As Iris is a free spirit who only attacks in self-defense, it is unknown if she becomes more militaristic and warlike in her Roman aspect.

In The Son of Neptune, Iris appears in her Greek form even though she meets two Roman demigods: Hazel and Frank.


Iris presumably possesses the standard powers of a goddess. Though the vast majority of her abilities are unknown, through the demonstration of her son, Butch, it is reasonable and logical to deduce that she possessed the powers of:

  • Transgressing Realms: Due to her status as the Messenger of the Gods, Iris could freely go into any realm without an invitation, even the Underworld, just like Hermes.
  • Superhuman Speed: Also due to her status as the Messenger of the Gods, Iris could move at supersonic speeds.
  • Control of Animals: Iris was able to summon pegasi, indicating that she had a level of control over them.
  • Rainbow Manipulation: As the Goddess of the Rainbow, Iris has divine authority and absolute control over the rainbow. Her jurisdiction over this province also grants her the abilities of:
    • Rainbow Generation: Iris is able to create or generate rainbows.
    • Energy Blasts: Iris is able to unleash blasts of multicolored energy.
  • Photokinesis: As the Goddess of the Rainbow, Iris also has the divine authority and absolute control over light. Her jurisdiction over this province also grants her the abilities of:
    • Rainbow Fire Manipulation: Iris could use light from her rainbows to create multicolored flames and burns to ward off enemies.
    • Rainbow Beam Emission: By utilising rainbows reflected off objects, Iris could project them off as rainbow-colored beams that could cause great damage in buildings.
    • Blindness Inducement: Through utilising the rainbow's light, Iris could blind enemies.


Iris is also able to create Iris messages. To Iris Message someone, you must find or make a rainbow (easier in modern times with the advent of the water hose with which you can get a fine spray), and throw a drachma through it, then say:

"O, Iris, Goddess of the Rainbow, accept my offering."

and name who you wish to speak to and where they may be found. It has changed in The Son of Neptune, instead you can use Fleecy's direct number:

"O Fleecy, do me a solid . Show me:__________________"

Then name who you wish to talk to and where.

As shown in The Sea Of Monsters, you can also telepathically send an Iris Message.

She is also friends with Chiron (and has been for centuries), allowing him to eavesdrop on some Iris-Messages as shown in The Sea of Monsters.

Roman demigods do not use Iris-Messaging, as by the time that Rome conquered Greece, they used more advanced methods such as "giant eagles" or their road system.
