LOL! Granted. And it could easily be argued that Alta-Invincibles were not as powerful as Mark due to whatever history they had in their dimension. (buncha evil couch potato counterparts) And simply due to the enormous volume of writers Hulk has had in his history his "power levels" has fluctuated wildly. It's the nature of the beast with the big two.
Damn, with everything invincible been through, and survived, i give him serious cred. But hulks a freak of the universe, friggin unstoppable. This could really be an interesting match. Could go either way I'd think. Great sketch Bonus points for dried out marker shading for the win.
