this is about as bad as the PPR forum I really think that movie 6 should have the best battle of all the 6 movies and battles involving spidy, venom, and carnage usually span more than one issue that's how crazy those battles get.
also in the comics Venom and Carnage are almost the only two villains who outclass spidy in every way and should win because of the following: they don't set off his spider sense, they're stronger, faster, they know what he knows, they know who he is under the mask, carnage can craft weapons from his hands, carnage is immune to sonics, venom's webbing is stronger than spidy's and carnage is so freakin powerful that it takes both Spidy and Venom to take him down.
even with all this stacked against him spidy is still able to beat them but it drains him when he does fight them.
I have two videos for those who are still against the symbiotes. these three videos will give you a little insight into them, really they will educate you.
