Yeah, I've got to agree with Colossal Spoons.
I've dropped Ultimate. It's still on my pull list, so I flipped through the issue, read a few lines, saw a few pictures, then put it back in its wrap and set it on the shelf. Eh, what I read of the ending didn't much impress me.
But I did take note of Colossus obviously fatigued, getting tossed around, his arse beat, etc. I didn't actually see the Multiple Men holding him down, but... that's just silly. And I'm a Madrox fan, heh.
Like Spooney said, Colossus took down Thor and Iron Man, and eventually was only stopped due to a pinpoint nuke-arrow. He carried a submarine from the ocean floor up to shore. He stopped a train dead in its tracks.
And now he's getting beat up by the Brotherhood and/or the E-Men? I'm not saying he's invincible, but who threw him? The Multiple Men? I doubt they could all lift him. Blob? Pfeh. TOAD? Hahaha. Sure, several of the E-Men could chuck Colossus, but I dare say that he'd get up just fine and proceed to pummel them.
I missed jumping off the sinking ship that was Milligan's X-Men, so I'm making up for it here. Oliver's bad art has brought these two issues down, but he's only a fill-in, so that's almost a moot point. It's the writing, the sudden character fluctuations and power fluctuations, and, of course, the editor not doing his damn job. (Then again, it could be said that Kirkman isn't doing his job.)
