Evil JLA vs Evil Avengers

well what he actually did was discover "uderspace" and "overspace" and thus he created a replica of the original avengers mansion only it was infinite in size with countless rooms coridores etc. and the best part was that the doors of the mansion could lead to any place on earth, other planets or even other dimensions

That's pretty bad ass. I think that's above anything Brainiac has done right there. Pretty recent, right?

BTW, that's pretty much Reed level, since Reed created a pocket universe for Ben.

it was in the last 5 Mighty Avengers issues.

he actually did discover something no other mind in Marvel Earth knew was there (or even if they knew they never utilized it).

so.. evil avengers win?
