X-Men: The Last Stand draws much of its plot and characters from the source comic books; however, while some of the X-Men characters and details remain similar, a number of comic book elements are altered for the adaptation. The film's plot concerning the emergence of the Phoenix draws from Chris Claremont's 1980 "Dark Phoenix Saga" in The Uncanny X-Men. Whereas in the film, the Phoenix is Jean Grey's evil "split personality", in the comics, the Phoenix is a fiery, Phoenix-like alien entity and force of nature that bonds with Jean. The cure for mutant powers can be seen in Joss Whedon's 2004 "Gifted" story arc in Astonishing X-Men. X-Men: The Last Stand is the first, and so far only, X-Men film to feature the five original X-Men -- Cyclops, Iceman, Beast, Angel, and Jean Grey on the team; however, the characters' backstories and positions within the team are altered. Other characters are translated even more loosely. Many of the Brotherhood shown in the film, for instance, including Spike, Psylocke and Multiple Man, are not Brotherhood villains in the comics. The mutant named Kid Omega resembles a character named Quill in the comics, rather than the hyper-intelligent comic book Kid. In the film, Psylocke has a red dagger tattooed above her left eye, and she is able to hide in shadows; this is a reference to a period during which Psylocke was connected to a substance called the "Crimson Dawn", which gives her powers beyond her innate mutant abilities of telepathy and telekinesis that manifests as a psionic knife/katana. Brotherhood member Callisto is depicted with superhuman speed and the ability to sense mutants' power levels. In the comics, Callisto is the leader of the Morlocks and has neither ability, instead, possessing acute senses. In the comics, Juggernaut is Xavier's human step-brother who acquires power when he finds a mystical stone; in X-Men: The Last Stand, however, Juggernaut is a mutant, and there is no mention of a relationship with the professor. Whereas he is usually gruff and violent in the comics, his line "Don't you know who I am? I'm the Juggernaut, bitch!" alludes not to the comics, but to a video (The Juggernaut Bitch!!) in which the video's creators talk over footage from X-Men: The Animated Series. Familiar details from the X-Men mythos permeate the film. The X-Men are shown training in the trademark Danger Room, a training complex within the X-Mansion. A giant, mutant-hunting Sentinel robot appears as a hologram inside the Danger Room. The fastball special, in which Colossus throws Wolverine toward an opponent, appears in the film twice, the targets being Magneto and a Sentinel. Beast's line "Oh my stars and garters!" appears frequently in the comics. One of the president's advisers is named Trask, an allusion to Bolivar Trask, creator of the Sentinels. Kitty Pryde's run through the pharmaceutical complex while being chased by the Juggernaut mirrors the character's similar fight against an alien in Uncanny X-Men #143. Finally, Wolverine's killing Jean bears some similarity when he killed his love Mariko Yashida at her request to spare her a painful death from poison (see Wolverine Vol 2 #57), as well as in New X-Men, in which he kills Jean to spare her from a more agonizing death burning up in the Sun.
