10 Moments Marvel Have Chosen To Ignore

10. Legion Is His Own Father

Legion is the mutant son of Professor Charles Xavier and Gabrielle Haller. He suffers from severe mental illness, including dissociative personality disorder.

Holding Magneto responsible for the failure of his father'dream, Legion uses his mutant powers to travel back in time and kill the Master of Magnetism BEFORE he becomes his fathers greatest enemy. Only to end up killing Xavier instead and ushering in the fabled "Age Of Apocalypse".

As far as Marvel is concerned this is pretty much the events of the "Legion Quest" storyline. However, those who have read the book know this is not the case. Legion returns to Israel where a young Erik Lehnsherr and Charles Xavier first meet through a mutual friend Gabrielle Haller who is a patient at the hospital where both men work.

And here is the moment where the wheels come off.

While Xavier and Lensherr are out for the evening, Legion proceeds to take on his fathers' form and seduce his mother. As the two begin to kiss, just off the panel, we cut away to the next part of the story. Only for a group of time-displaced X-Men, Magneto and Xavier to confront Legion, who is found standing over the ravaged body of Gabrielle Haller.

The rest is pure mathematics. David Haller is not more than twenty years old at the beginning of the "Legion Quest" storyline, and the primary struggle young Charles Xavier is having is whether or not he should act upon his feelings for his patient Gabrielle Haller. The off-panel assault is never mentioned again but is never explicitly retconned either.

If the original plan was to reveal that Haller was his own father, then it was one which was never followed up on, if not then what was the point of the sequence as it has no bearing on the characters or the "Age of Apocalypse" storyline that it kickstarted?
