Suggested by Sonic Owlman has his super intelligence but at the end of the day that won’t be enough to stop Metallo. Metallo has gone toe to toe with Superman on many occasions. Even without his Kryptonite advantage, Metallo’s raw power is considerable. He shouldn’t have much of a problem overcoming his Owlman’s hand to hand advantage and a few good hits would end this. Metallo wins.
What a nice battle this would make in the comics. Metallo should probably still win.
It’s really hard to go against Metallo for sure. Owlman’s best bet is trying to create some kind of device on the fly
