Iris

"Let's live together, in a world where only Reploids exist..."

- Iris on her deathbed, her idealistic world to live in

Iris (アイリス) was a Reploid from the Mega Man X series that worked as a Navigator for Maverick Hunters. She was also Zero's love interest and the younger twin sister of Colonel. Like her brother, she speaks with an Australian accent in the English language versions of Mega Man X4.

Appearance
Iris appears as a young-looking female brunette Reploid with green eyes and very long hair, comparable to Zero's length. Her armor consists of a blue and red scheme with yellow accents and is modeled into the form of a dress, her limbs being white, her boots white, and her hands appearing to have segmented knuckles. In X4, her boots gain a black outline and have a defined lavender color with the addition of a red beret on her head. In Mega Man Xtreme 2, Iris appears to be slightly younger than her previous appearance (as Xtreme 2 chronologically predates X4), and along with lacking her beret, she has a small section on her upper chest with the insignia of the Repliforce army.

After taking Colonel's core into her body in Mega Man X4, she appears as a Ride Armor-like being with a purple color scheme and a pair of wings. It is unconfirmed as to whether she entered a Ride Armor vehicle or became a similar being herself. However, she reverts to her original form after her defeat, suggesting that she was inside an armor.

History
Repliforce scientists attempted to develop an ultimate fighting Reploid with both a high fighting spirit and peace-loving heart, but the differences were ultimately considered irreconcilable and the project was considered a failure. The scientists then decided to split them up into two Reploids, resulting in the creation of Iris and her brother Colonel. Her half was of the peaceful arbitrator, and Colonel's was of the strong-willed fighter.

Mega Man Xtreme 2
The Erasure incident was Iris' first mission as a Navigator for the Maverick Hunters. She took the roles of both Navigator and item development by making power-ups out of the Maverick's DNA Souls. In the Xtreme Mode ending, Zero feels bad that her first mission was a tough one and the Colonel will blame him.

Mega Man X4
When the Repliforce was labeled Maverick after the Sky Lagoon incident, both X and Zero were assigned different missions to gather information about Repliforce's coup and to cut off their support lines. Iris assisted Zero on his missions as being his operator, like during the Erasure incident. However, Iris herself was part of Repliforce while her brother, Colonel, was Repliforce's second-in-command and therefore an imminent target for the Maverick Hunters. When the two of them battled in the Ceremony Hall of Repliforce's command center, it was Iris who stopped the two Reploids from terminating each other by begging her own brother to stop, since Zero had previously saved her life after the Sky Lagoon had crashed. Colonel, who had always regarded Zero as a friendly rival, backed off. Zero, on the other hand, stated that someone had to stop Repliforce at all costs, much to the grief of Iris.

When Repliforce's coup began, Zero rushed to the space port to stop the ascension of the military troops to the newly constructed space station of Repliforce, Final Weapon. There, he battled Colonel again, this time killing him. After that, Zero traveled to Final Weapon where he was encountered by Iris, who was blinded by the grief of losing of her brother and anger for Zero killing him. She had salvaged Colonel's control chip from his remains, fusing it with her own programming, thus causing her body to transform into a massive winged Ride Armor-like combat form which Zero was forced to battle. Even though Zero didn't mean to, he damaged the exterior power core of the structure, resulting in the destruction of the armor. In addition, Iris's incorporation of the salvaged control chip for Colonel also fried her programming to be irreparable. Zero hurried to Iris's body, but, it was too late to save her, and while she lay dying in his arms, she whispers to him that she did all this because, even though she knows it is nothing more but a fantasy, she wanted to live in a Reploid-only world together with Zero. Zero, totally overwhelmed by her death, began questioning his own reasons for fighting, becoming the infamous "What Am I Fighting For!?" scene.

Sigma would later antagonize Zero further, by revealing his involvement in the whole ordeal. He even taunts him by saying, "Iris is waiting for you!" before their battle.

After Final Weapon is destroyed, Zero flies back to Earth in an escape shuttle, but he is tortured by the thought of being unable to save anyone.

Mega Man X5
Iris reappears as a memory in Zero's ending, where an image of her is seen by Zero as he lays dying and all he can do is quietly apologize to her.

Powers and Abilities
As a normal Reploid, Iris is a skilled Navigator for the Maverick Hunters.

In her combat form created with Colonel's core, Iris can fly freely and has two attacks:
 * Floating Mine - Iris goes to the corner of the room and releases numerous floating mines from her body when hit. These mines help her absorb damage temporarily.
 * Laser - Iris goes to a corner of the room and fires a large laser beam horizontally from her cannon. When the core is present, it will assist by flying under the floor and fire a vertical laser beam.

Other appearances

 * Iris appeared alongside Double in one of the battles from the X Challenge in Mega Man X Legacy Collection, allowing players to fight against her as X.
 * Iris appeared in Battle Memory from Rockman Xover.
 * Iris appeared as an event character in Zombie Cafe.
 * Iris appeared as an event character in Dragon Poker, available for a limited time in the game's shop alongside a Life Energy orb and other contents.

Rockman Online
In the now-cancelled Korean MORPG, Iris appears working as a Navigator (along with Alia) for the UCA (United Continent Association) in the games first teaser trailer. As this games story is said to take place in the far future where the characters from both the Mega Man and Mega Man X series have long since passed away, this Iris (much like the other series robots and Reploids appearing in the game) is a copy/recreation, embedded with the DNA Soul of the original.

Project X Zone
Iris appears in the crossover RPG as an event character. She makes her only direct appearance in Chapter 29, "An Unbeatable Love" (負けない、愛 Makenai Ai in the Japanese version).

With X and Zero shocked to see Iris alive and well, X recognizes her as the younger sister of Colonel, and "the girl from that Repliforce incident", which suggests that the events of this chapter take place after Mega Man X4.

She still wishes to live in a world only composed of Reploids together with Zero, but he reminds Iris that such a world is nothing more than an illusion. He is then asked by her if a Reploid only world is meant to be his purpose and desire, part of the reason why Iris is present. Afterwards, Zero suffers an emotional breakdown, pondering about whether or not a Reploid only world was really the reason he was fighting for, with Vile taunting him for an A-Class Hunter getting emotional over Iris's wish, claiming that he and Zero are, in truth, the same. X reminds him of how he promised to stop the former if he ever doubted their ideal, and expresses how he didn't want the latter to feel like that before himself. Zero becomes paralyzed with anguish and is unable to move.

Confused about Iris at first, the other characters present then realize that Zero is in trouble, and X asks for their help to protect him from danger, while attempting to defeat Vile at the same time. The game splits the winning conditions down to two options: reach Zero by the ninth turn to heal him or defeat Vile, otherwise a game over will be declared. Until then, X's unit is paralyzed and unable to fight.

After any of the other party members reach Zero and heal him, he eventually recovers from his emotional breakdown and recalls his duty as a Hunter, and tells Iris that a Reploid only world is impossible. Aura from .hack appears and states that Iris and her feelings are not supposed to be present, hence causing her to fade away. Before she vanishes however, she gently suggests to Zero that she is happy to see his conviction didn't change, and encourages him to never give up before bidding him farewell. His resolve restored, Zero confidently declares he will rejoin her someday.

Iris is mentioned again by X in Chapter 37, where the latter comments about Vile using her back in The World, as well as how he hurt Zero emotionally.

Archie Comics
For unknown reasons, Iris was not cloned by Sigma-1 during the events of Worlds Unite, a fact that Zero commented on during the battle between the Maverick Hunters and their allies and Sigma's Maverick Army. Though he and his comrades recognized a number of fallen enemies amongst Sigma's minions, Zero noted that neither Iris nor Colonel were among them.

Rockman X4 manga
In the manga Iris works for the Repliforce. She helps Zero after his battle against Jet Stingray.

Trivia

 * Iris's presence as a trainee Navigator in Mega Man Xtreme 2 was due to the development team feeling sorry for her in the events of Mega Man X4, as detailed in Mega Man X Official Complete Works. The game also hints towards her feelings for Zero, and vice-versa, with the two having dialogue specific to Zero's game alone.
 * Iris's bio in Mega Man X Legacy Collection is: "When Zero saves her life during the Sky Lagoon incident, she finds herself falling for him."
 * Iris's final words to Zero in X4 would later be repeated by Mega Man Zero 2 antagonist Elpizo upon becoming Dark Elpizo, the main difference being that he didn't intend for Zero to be part of his plans.
 * Iris's design featured blue eyes in Mega Man X4, but every following appearance depicts her with green eyes.
 * Iris's death scene in X4 was later redubbed by Lucas Gilbertson (Zero's voice actor in Mega Man X8, Mega Man X: Command Mission and Maverick Hunter X) and Ashley Schroeder. The redubbed version is not an official production by Capcom, and Schroeder does not replicate the accent Michelle Gazepis voiced her with originally.
 * During the battle with Iris, she will eject Colonel's core on her own if Zero takes heavy damage and the core is not present.
