I'm still working on a script. This is what I want the lineup for the Brotherhood and the X-Men to look like by the end:
BROTHERHOOD:
-Magneto
-Pyro
-Mystique
-Callisto
-Scarlet Witch
-Quicksilver
-Tempo
-Avalanche
X-MEN:
-Storm
-Logan
-Scott
-Hank
-Rogue
-Bobby
-Kitty
-Warren
-Pete
-Kurt
-Gambit
Yeah, there are a lot. Im thinking of cutting a couple out and/or reducing the development of a couple characters, but Im not sure who would get cut. Here are some basics of the characters ATM:
MYSTIQUE: Mystique is in the Brotherhood as an undercover agent. Not knowing of her continuing ties to the Brotherhood, and envisioning the good publicity it would give the "cure", a Senator hires her on as a secretary. She plays along to get information, but kills him when her powers return, and goes back to the Brotherhood full-time.
MAGNETO: He's on his own for a while, with no connection to the Brotherhood. His powers return, though, and he uses them to rescue Scarlet Witch and Quicksilver, then returns with them to the Brotherhood. Neither he nor they know that he is their father, but it is alluded two in subtle ways. He reveals that he was once married to a human and had a daughter, but his daughter was killed by a group of bigots. His wife was already disapproving of his work with the Brotherhood; but after their daughter was killed, Magneto vowed in front of her to kill all humans (and proceeded to kill all the humans in the area). This scared her and she fled. He reveals in passing both that it was almost 30 years ago, and that he and his then-wife made love the night before she left him; all of which sets up the timeline for Scarlet and Quicksilvers conception.
PYRO: He took over the Brotherhood in Magneto's absence, but gladly gives it back to Magneto upon his return. He is very strongly attracted to Scarlet, and makes numerous (unsuccessful) passes at her. He reveals that he came from a broken home with an abusive father and a promiscuous mother, that his powers manifested when his father was grinding a cigarette into his arm, and that he killed his father by burning down his fathers house while the guy was in it.
SCARLET WITCH: Hates being called a "witch", so the Brotherhood calls her "Scarlet." She hates the Brotherhood, but feels stays out of obligation to Magneto for saving her and her twin brother, Quicksilver. She tries to befriend Pyro, but is put off by his attempts to make it more than a friendship. She knows nothing about her parents, but has heard rumors that her mother was human and her father was a powerful mutant. She is relatively stoic, because when she lets her emotions loose, she has a hard time controlling her enormous power.
QUICKSILVER: Has a much less prominent role than Scarlet, but still significant. Hes protective of Scarlet, causing hostility between he and Pyro because of Pyros repeated advances toward Scarlet. He is initially attracted to Callisto because they have the same gift and therefore she can keep up with him, but the attraction is quickly extinguished when he realizes what the Brotherhood - and therefore Callisto - is about.
CALLISTO: Is initially attracted to Quicksilver because they share the same ability, but she loses interest when she sees that he opposes the Brotherhoods cause.
TEMPO: Has her same abilities from the comics (can telepathically alter a persons perception of time), but also has the ability to stop time and can also replay events that happened in her surroundings - much like Sway. She was recruited by Pyro during Magnetos absence, and is attracted to Quicksilver.
AVALANCHE: No real substance to the character - hes just the muscle of the group, recruited by Pyro during Magnetos absence.
STORM: The new leader of the X-Men and Xaviers school. With the mansion being short staffed, Storm is struggling to keep the institution afloat. Initially angry with Rogue for taking the cure, she accepts Rogue back at Logans urging. She and Logan have both a very close and very conflictive relationship, and kiss at the end of the movie (though she abruptly leaves the room before they go any further.) It is revealed in a scene with Rogue that she was a goddess in Africa as a teenager.
LOGAN: At the beginning of the movie, is Storms only real help at the beginning, though he is very reluctant to help and hates teaching. Toward the end of the movie, he has a big fight with Storm about his passivity, and steps up to help her. He has no hard feelings toward Scott, but during an emotional altercation when they first see each other, dares him to blast my head off because of the pain he feels after killing Jean. He is still close friends with Rogue, and at the end of the movie, shows romantic interest in Storm by kissing her (though they didnt go any further, and she left the room abruptly after the kiss). It is revealed that he lived in a mansion as a child, his mother had an affair with the gardener, the gardener shot Logans father - immediately after which, Logans claws came out and he killed the gardener, which prompted Logans mother to kill herself.
ROGUE: Gave her virginity to Bobby after taking the cure, and was blindsided afterward when he told her he couldnt live with her taking the cure and broke up with her. During her time as a human, she moved in with her new boyfriend, another ex-mutant named Freddie. She became pregnant (I was gonna name him Logan), but when her powers return overnight, she both lost the baby and killed Freddie. Upon her return to the X-Mansion, Bobby - not knowing that she got her powers back - makes some nasty comments about her deciding to become average. She answers by kissing him until he passes out. Afterwards, she plays around with his powers and realizes that there is a good side to her powers. Here, a more edgy and powerful Rogue emerges. While showing off to Storm, her ability to absorb memories manifests, which she later uses to help Logan regain some memories. Though it takes some time for her to get over her feelings for Bobby, she vows not to be his next Kitty. She has a minor attraction to Gambit.
BOBBY: Makes love to Rogue after she is cured, but is guilt-ridden afterward and breaks up with her. Angry and on the rebound, he quickly hooks up with Kitty, which brings about hostility from the other mutants his age (whatever Rogue did, she was still family.) When Rogue comes back, his feelings for her return exponentially; though in their first encounter, partially because of Kittys presence, he tries to cover it up with hostility and nastiness (which prompts Rogue to knock him out with a kiss).
KITTY: Takes on a minor spoiled brat role in this movie. She and Rogue have a hostile relationship that moves from initial enemies to reluctant friends. She is upset over the fact that Rogue is accidentally stealing Bobby away from her emotionally.
GAMBIT: Helps Scott find his way back to the X-Mansion, and reluctantly joins the group. Hes been on the streets most of his life, gambling and stealing his way from place to place, but is now ready to redeem himself by joining the X-Men. He has a hard time, though, humbling himself by admitting that he wants this. He flirts with the girls, but is seriously attracted to Rogue (which makes him hostile toward Bobby). Scott initially takes on a sort of father or big brother role with him, which Gambit resists. Warren and Pete are his roommates.
SCOTT: Despite the X-Mens assumptions, actually survived the incident with Jean Grey at Alkali Lake. He spent first couple months afterward in a psychically-induced coma, and the rest of the time in exile until he met Gambit - who helped him return to the X-Men. He helps Gambit through his reluctance to reach out to the X-Men, and fights for Gambits admittance into the School when Logan and Hank have objections. Scott rages at Logan when they first see each other again, because - justified though it was - Logan killed Jean. They reconcile by the end of the movie, though.
HANK: Was the US Ambassador to the UN; but as the cure wears off and talk of human-mutant war heats up, hes asked to step down. He rejoins the X-Men, taking on the role of doctor, and is almost a second-in-command to Storm.
PETE: Not much substance to this character. Hes friends with Warren and Bobby, though he expresses his disapproval of Bobby and Kittys relationship and is met with defensiveness.
WARREN: A quiet, religiously-confused young man who bonds with the devout Catholic Kurt. He reveals that he used to be a Christian, but the rejection hes faced from his father and the rest of the world made him question his faith. At the end of the movie, hes seen reading a Bible, and he takes on the code name Angel in reference to a comment made by Kurt about Warrens physical appearance.
KURT: Left the X-Men a long time ago because, though he admired their work, didnt like to participate in the violence. However, he was captured by the government and used as a lab rat in the creation of the cure. He escapes the lab, and lives in exile until the X-Men find him and re-recruit him. There, he connects with Warren, compassionate toward Warrens religious confusion and admiring of his angelic appearance.
