yep, well i thought it was morph too because of the animated series. Morph was taken out by a sentinal after the x men raided a mutant control centre to destroy mutant files. Beast was taken out too. Cyclops led the team away presuming them dead and for the good of the team, much to wolverines anger.
Later, morph returned to the mansion and caused havok, changing into each of the x men and taking them down one by one. Gambit was knocked out after kissing rogue when she got back from the fight with storm who ended up in hospital cuz beast did not turn up. Beast was in fact locked in the danger room by morph. Jubilee was sent to the friends of humanity, wolverine was out for some reason and he ended up saving jubes life. Confusing i know.
Well they all got back to the mansion but wolverine sniffed out morph who was disguised as the prof. He flew off in the x jet, wolverine followed but ended up losing him.
Morph then appeared after cyke and jeans supposed wedding but he was the minister so teh marriage was void.
It turned out sinister found morph and turned him against the x men by implanting a chip in morphs brain after the sentinal incident. He wanted revenge on scott for leaving him behind. On the honeymoon island where they were captured morph nearly got his revenge but cyclops talked him out of it and made him see sense. He then turned on sinister for making him go against scott and the x men. Then morph left.
I presume he went to Moira mctaggert on muir island cuz that is the next time we see him. His chip was removed. He later came back to the x men to fight of the re-awakened sentinal program but realised that he just wasn't ready to come back to the x men even though he just took out the head sentinal.
His last appearance is the last but one episode when he morphs into xavier after xavier is attacked on live tv by normal people. The mutants revolt but morph sends out a broadcast as xavier to keep the peace. Xavier later dies but with magnetos help he is brought back by the Shi' Ar.
I watch too much tv.........
