Seriously, has there ever been a bigger disconnect between how cool something should be in theory and how lame that same thing always turns out?
Metallo is a killer cyborg with a heart of kryptonite. This sounds ridiculously cool and badass.
But I can't think of one instance where Metallo actually was cool or badass in any of the comics he appeared in.
The closest in the comics had to have been SUPERMAN #1 (volume 2) in 1987 during the beginning of the Post- Crisis Era with John Byrne. And that lasted for exactly one issue.
The S:TAS version on TV was probably the coolest Metallo ever was, but that had to do more with who was voicing him than anything else.
Metallo is nothing but a hench.
He's too dumb to be a legit threat but too rotten to be sympathetic.
He's a mook. But he should be too cool to be a mook.
There has to be some way to improve the character so that he is a better, worthier antagonist to Supes.
Or, if there is not, trade him to another DC franchise in need of someone like him. He could be the Sabretooth to Cyborg (Victor Stone)'s Wolverine, perhaps.
Something has to change.
