Strength level
Metallo has superhuman strength, the limits of which seem to fluctuate depending upon which upgrades he is using at any given moment. In his first iteration, Metallo was able to lift (press) approximately ten tons.
Weaknesses
Metallo's brain was one of the few biological components left in his body, and as such, represented his only true vulnerability. So long as his brain was intact, Metallo would always be able to generate a new body for himself.
