I think it depends on what

has been eating lately and how much. If he's been doing Cinco de Mayo with

, he's got WMD (chem, and perhaps bio too, maybe even nuke).
In any case

has it all over any of them cause he's obviously a rocket scientist and his space based laser already has acquired and locked on all the others as targets, with a blink of his left eye (which you can't see because of his extremely thick glasses, a 3 nano-second burst of the 360 mega-peta watt x-ray laser will reduce any of them to a wisp of quarks. The whole bunch can be taken out in .03 seconds. That's what's got

so concerned.
Of course,

is immortal so he doesn't care. Actually, he was the one that gave

the science kit for christmas.
However, laser or not,

has a secret doomsday weapon, even if you cream him, there's always a chance you'll slip on his skin, do a tripple backflip with 4 and a half twists, landing on your head and breaking your neck, which is just as well as the initial slip wrenched your back and you'd be living is mortal pain anyway.
