Punisher/Megatron vs IronMan

Okay, let's take the punisher, who is an uber-badass for a guy with nothing TOO special about him, and IronMan, who we all know, has an uber badass suit. Doesn't really sound like a fair fight, does it? Well, let's up Punisher's arsenal. Let's give him The Might Megatron, of course, keeping him in his gun form. Who shall win???

in his gun form wouldnt he still be bigger than punisher??so how does that help???

lol, with a name like "thundercracker" i'd imagine you would already know that answer. Some Transformers (specifically Megatron and Soundwave) are capable of changing size when they go into their alternate modes, both are capable of becoming small enough for humans to carry/weild.
