Unfortunately, Alex Mercer is leaps and bounds more powerful than any of the characters here, and you've essentially just copy/pasted his powerset and edited it to be even more powerful. Lifting tanks with ease means be can lift well over 60 tons, in addition to running several hundred miles per hour and being more durable than anyone else in this fight. He's already overpowered for this particular fight, and that's without even considering his shapeshifting abilities.

Nothing any of our characters can do will actually be able to put Drax down, since Mercer survived a nuke and you've basically just copied him and made changes to be even better (and none of us can generate anything even close to the power of a nuke).

All this said, I'm not telling you you shouldn't use Drax in another fight, just that he's much too powerful right now for this fight. I'm not even sure all of us together could take him on.

@Derp: If he writes Drax like a copy of mercer, your flames are just going to tickle.
