There are two volumes of X-Men: Legacy. The first was a renamed X-Men vol 2, which was named X-Men: Legacy from issues 208 to 275. For more information on that run, please see X-Men (1991).
The second volume of X-Men: Legacy came out in 2012-2014. The book was written by Simon Spurrier, with art by Tan Eng Huat and lasted for 24 issues. It centered around David Haller, Professor Xavier's son, also known as the Omega-level mutant Legion. After the Age of X, David has been training at a monastery in the Himalayas, making sure to keep control of his other personalities, keeping calm and collected and making sure that nothing disturbs his tranquility and peace.
And then his father died. And his tranquility and peace were shattered, his personalities were unleashed from the prison inside his mind, and nearly all the progress lost. But David won't sit back and let that happen. Caging each personality in his mind and making sure he doesn't hurt anyone is his top priority.
Of course, his other top priority is finding the man who killed his father. And maybe, in the process, saving all of mutantkind.
Or destroying it.
Tropes in X-Men: Legacy vol 2:
- Apocalypse Maiden: David Haller. As one of his personalities put it:Professor Y: Shh. Listen. Learn. The event that Luca foresaw. The grand evil which will destroy all mutantkind? The genocide only the girl—only Blindfold—can stop? It's you, David. It's you. You wretched little disappointment. You're fated to wipe out your own kind, boy... and the girl you just saved? She's fated to try to kill you, just to stop it
- Blessed with Suck: Aside from Legion himself, there is Santi Sardina, whose mutant power is "positivity absorption." Which basically means that they absorb or take credit for others accomplishments, having other people praise them continually for things they didn't do. And the power is always on. This is why he decided to contribute artwork anonymously.
- Cain and Abel: Blindfold and her brother, Luca. He was the one who blinded her when they were children.
- Creepy Twins: Karasu and Sojobo. Even though they are creepy, they aren't evil and David ends up saving Karasu.
- Evil Doppelgänger: Due to the shock of Xavier's death, David developed a new personality that was basically an evil version of Professor X. He was called, alternatively, the Fiend or Professor Y and appeared as a yellow, goblin-version of Professor X.
- Faceless Eye: Luca didn't die, he just manifested as a pair of glowing blue eyes.
- Gambit Pileup: David often uses complicated schemes in an attempt to secure a better world for mutantkind. However, there are also the schemes of his other personalities, including Professor Y, as well as the Red Skull, who wants to use Xavier's brain to cause worldwide hatred. Throw in the X-Men's own attempts to stop David and Blindfold's knowledge that, in the future, she will have to kill Legion to save the world, and you get a mass of gambits (although not Gambit) which tend to overlap.
- Important Haircut: The cover to the last issue shows Ruth shaving David's head. This is actually just symbolic, as she attempts to prevent him from ending the world.
- Meaningful Rename: In the last two issues, as Ruth decides to finally confront David and stop him, she changes her code name from Blindfold to Destiny, the same code name as her grandmother.
- Mental World: A lot of the book takes place within David's mind, as he has numerous other personalities. His Mental World, then, is often used as a prison he calls the Qortex Complex, as he has to control those personalities and use their powers for himself.
- Naked People Are Funny: In issue #10, Ruth uses Cerebra to project herself in David's bedroom to talk to him, only to discover he Sleeps in the Nude. Even though being a Blind Seer she can't technically see, she's still mortified, and her embarrassment is Played for Laughs.
- Parental Abandonment: One of the big things that David is working through — his father didn't know he existed for a long time and his mother left him with Moira MacTaggert to work with his powers instead of staying with him. This is why he basically considers Moira his mother, although he does try to reconcile with his mother...before she is shot by a bullet meant for him.
- People Puppets: David eventually realizes that Marcus Glove has been braindead for quite some time and has been controlled by the Red Skull.
- Retgone: In the end, David decides to prevent his own birth in order to erase himself from existence. As later books show, however, this didn't take.
- Star-Crossed Lovers: David and Ruth. They love each other, but Ruth is destined to kill David to prevent him from ending the world. To prevent this from happening, David erases himself from existence.
