Dr. Eggman (IDW Comics) sets up shop in the mainline DC/Marvel Universe

[Guy1]

We can all agree he'll have the most epic 'stache in either universe though right?

Beast?

Unless you're referring to Dark Beast (Age of Apocalypse), I don't think that Regular Beast could counteract something like the Metal Virus; he is neither a roboticist or a geneticist (after all, the Metal Virus is biomechanical/techno-organic in nature; think of it as a primitive/prototype version of machine phase matter-- the same stuff that turned John Connor into a Terminator).

Yes, mainline Beast is a genius, but you'd think that things like (nano)robotics and genetics would be beyond his paygrade...

beast created a time machine and used it to bring the original xmen to the modern day.

that puts in the top ten big brains of marvel.
