Colossus made of pure adamantium, vs Maestro Hulk and War Hulk
Who would carry this one fellas. Keep in mind since Colossus is now composed of adamantium his strength and endurance should also get a DRASTIC increase. Also note that Maestro Hulk is a professor Hulk from an alternate timeline who got further irradiated by gamma radiation because of several nuclear wars. His base strength is reputed to be about 200 tons. And to even the odds if Colossus is knocked out he remains in his armored form.
