X-men's greatest Moments:
Uncanny X-men #200
The Trial of Magneto!
Magnus has surrendered to the authorities and is on trial for his crimes in Paris, France. Defending him are his old friend Charles and Gabrielle Haller.
Meanwhile, terrorist attacks on various sites call for Magnus to be freed and even though the X-men fight back , they are blamed anyway.
Fun Fact: John Romita Jr is the only artist to draw two centennial issues for Uncanny- 200 and 300.
Gabby contends that since Magnus was essentially reborn after his return to adulthood, he has paid the ultimate price for his misdeeds
Magnus also speaks to the court
So who are responsible for the attacks in Paris?
Fenris aka Andrea and Andreas von Strucker. They are the children of Nazi/Hydra leader Baron Wolfgang von Strucker, who Magnus stole a lot of Nazi gold from in Uncanny X-men 159 (flashback)
Meanwhile, Madelyne is in the mansion home alone about to give birth..
A convenient flood washes Fenris away but the judges are safe. Xavier and Magnus come to in a nearby garden where Xavier asks Magneto for a special favor.
Context: Xavier was severely beaten by anti mutant students at Columbia University where he was teaching in issue 192. He was cared for by the morlock healer but kept pushing his body and mind in various crises until his body could take no more.
Corsair and Lilandra arrive to take him to Shiar space to heal him, but due to some attcks and technical trouble, they are unable to return to earth.
Status Quo - Irrevocably altered (As Omega Supreme would say)
Claremont writes Xavier out of the series for his longest period yet.
Xavier will be in space and will not return to the book till around issue 275!
He makes a one panel cameo in 203 and New Mutants for a couple of issues.
While 150 was the beginning of Magnus' reformation, this is the real time to see it in action. His role is more prominent in New Mutants as the headmaster. While he does assist the X-men here and there, after the Mutant Massacre, his role in Uncanny is severely diminished.
