Really, you can use anyone for him, Prof X is a popular choice for those that don't want to deal with his reverse controls phase. Colossus will go a long way for you though, I believe a youtuber named Brian Grant posted a video of Colossus doing GM fight if you wanna check it out. I dont fully recall the paths in there but I do remember there been one that was super easy, I think it started with Psylocke
I took tenacity path and BWCV cleared the whole path itemless. For GM, I used Doom, Ultron, red mags, KP and prof. x, I used some revives on phase 1 as I am average at intercepting, but after that it was way easier than I thought. Prof.x took care of reverse control phase.
