Piotr Rasputin is virtually unbeatable in his organic metal form as he has superhuman strength, virtually unpierceable skin, no need to breathe and phenomenal stamina.
Venom is an alien symbiote with incredible powers to take over people as well as super strength, agility and stamina.
Venom can be weakened by electricity or sonic weapons whereas Colossus in organic metal form is only weakened by Vibranium.
Assuming that Colossus can power up before Venom attacks then Colossus will win. Venom has nothing that can damage him and a hard clap of the hands will produce a sonic wave capable of hurting Venom.
If Venom can strike before Colossus powers up then he will easily consume him in one way or another.
Hulk is vastly stronger and more resilient than Colossus. There is nothing that Colossus has over the Hulk, save a suplex or judo throw he's been working on in the danger room. He'll put up a decent fight till Hulk gets a proper hold of him, then, depending on how mad he is, he'll either knock him out or contort his body. Either way, Colossus will wish you hadn't asked.
Abomination
hulk would destroy all of them. so hulk would win.
Dr octopus
sandman would lose to green goblin who would lose to dr. octopus who would lose to rhino who would lose to venom who would lose to: Electro. Why? He's the only one who doesn't have to move to win, and he beat all of them before, ESPECIALLY sandman and venom!
the black mamba because of its venom
Due to the strentgh of the fat-tailed scorpions venom the tarantula would not live even if it did win, so the fight would either be a draw or the fat tail
It is difficult to determine who would win definitively as both characters have unique abilities and strengths. The Hulk possesses immense strength and durability, while Venom has abilities like shape-shifting and regeneration. It would likely depend on the circumstances of the fight.
