It's all in the name of science...weird science.

I've been fiddling with this for a while, but I've been wondering...how would the "brains" of the Guyver-verse (i.e. Balcus, Hekkering) stack up to other genius-level characters from other universes?

Hmm...hard to say.  Its obvious that Dr. Balcus and Hekkering along with many other Chronos scientist have advanced degrees in biology, chemistry, anatomy, and now possibly alien tech, but to what extent is uncertain.

 

The ones that first come to mind that may be able to match them in those fields would be Professor X, Reed Richards, and Bruce Banner.  Of course there are other genius' like Tony Stark, Molark, and the Krulls, but their respective fields are different except maybe for the Krulls and other alien races with alien technolgy at their displosal, but to my knowledge there isn't another alien race like that of the Uranus, but of course I can be wrong.

 

As for the DC universe I am uncertain because I don't follow it as well as I do Marvel, but the ones I can think of would be Brainiac, Lex Luthor for not really being that intellegent, but would know how to in my opinion be a good Chronos operative of sorts.  The only other person I can think of is Batman, not for actually recreated Chronos' work, but I think he would be able to dissect it and figure it out if he was provided with samples and notes.

Tony Stark and Bruce Banner might be able to go head to head with Dr. Barcas. After what Tony did with Extremis....and of course.....accidentally creating Ultron. Than Bruce Banner accidentally blowing himself up into a green rage monster....I'd rest my case.
