There comes a point in every young mutant's life after showing up at the Jean Grey School for Higher Learning when they realise that becoming a member of the X-Men means there's a good chance that, sooner or later, they will end up dead. And then they get better! (For some characters, this happens a lot.)
It's not a trick question. Based on various depictions of the Xavier School for Gifted Youngsters, Professor X -- a paraplegic mutant telepath with a supposedly genius-level intellect -- somehow forgot to add wheelchair ramps to his own home. So we asked artists who have worked on X-Men titles over the years how the franchise's patriarch leaves his own house.
