Approaching the End
It's silly to keep debating this.
I, myself, have never seen Ult. Colossus as an arrogant person. He, like every other single character (and real person) may have acted "rudely" or "dickish" on some select occasion, based on the situation. It's obvious to everyone here (besides Grimm, apparently), that Ult. Colossus is indeed not an arrogant person, or a "dick."
I think we're also all mature enough to surmise our own opinions about the situation (after all, I don't expect Grimm to openly admit to disliking Ult. Colossus because the character is gay). However, like I said, I believe the posters here can make their own observations, and come to their own conclusions.
It becomes a problem, though, when Grimm begins to flame Ult. Colossus for being a "dick" or being "arrogant" or being "emo" or whatever the hell else vocabulary is being used today to describe a rude/unlikable person, and then can't provide valid and consistant proof of aforementioned character acting "dickish."
My two cents.
