1.Colossus beat Hulk. Hulk can't be weakned by small ball of fire. Colossus was wrong ther, only idiot would understand that, so I am assuming that You're doing it on purpose. IDK when You get an idea that Colossus know Hulk enough to think what makes him weak and doesn't. A specially that Hulk's HF allow him to recover from much stronger damage in seconds. I've seen that You've used Ghost Rider as an example... Person who is using demonic, Hellfire. In comparision to small dragon. That is... awkward.
2.Barda didn't prove her speed there... She just catched a lash... And she FAILED against that beam.
3.Is that even Post Crisis? Care to show context or better - tell me when they fought and when her enemy proved that is Superman level enemy (I mean, when she BEAT Superman/Supergirl, because "fighting" isn't a prove of anything).
1. He's been hurt by fire on several occasions and the dragons fire is quite powerful, so Colossus wasn't wrong. Hulk's healing factor probably only helps him recover from attacks from bricks like Colossus like it did in the first fight where Colossus's hits had no effect on him, but it probably takes him longer to recover from fire because it is his weakness. In the second fight Colossus only hurt him because Hulk was weakened by Lockheed's fire because fire can hurt him.
2. She proved her speed by catching the whip that has tagged Mister Miracle and Supergirl and you can in the scan that Lashina cut the boulder into three pieces while the boulder was still in the air, so you can't really dispute it. She lifted a continents weight and her hand was still up, so she wasn't taken out by it. Colossus would have died if her was in the same predicament.
3. I never said she beat Superman or Supergirl in h2h; I said she KO'd Superman with her Mega-Rod and took down Supergirl with it. It was the blast from the Mega-Rod that took them down. I even posted the Supergirl scan. The Wonder Woman fight if proof enough to show that Barda would stomp Colossus.
