Originally posted by FrothByteShe didn't really chuck that trailer. Yeah she kicked it and slid it some distance, but I wouldn't say that's as good as Colossus smacking aside an airborne bus into the side of a building. Sif isn't in Colossus' range strength wise and she wouldn't beat Colossus in a fight.
IIRC, Colossus didn't so much catch that bus as he redirected and pushed it over his head. Still, it's a valid feat. Best one he has other than throwing a big tire. Now let's get to Lady Sif's strength feats.She chucked a trailer (roughly the size of that bus) sideways and against friction with just a push of her foot. A casual palm thrust from her sends a full grown man flying a couple dozen meters through the air. And I assume being an elite Asgardian that she's at least as strong as the Asgardian farmer in AoS that easily crumpled a tactical knife in his hand.
Like I said, Sif has feats that put her within Colossus' strength range and Colossus was strong enough to hurt Juggernaut.
Not that she'd beat Destroyer either. The only reason she did somewhat well there was how nimble she was and how slow Destroyer was. Colossus isn't slow. He was in the first movie, but his brawl with Juggs had them both sending out flurries of punches to each other and mixed in successful blocks. It was a good showing, even if he ended up getting whooped.
