there's a difference in losing and jobbing, and that's especially evident when the character, like Prometheus, is one who is all flash, no substance.
there was absolutely NOTHING to the character except a "kewl" costume, one quick "let me get this guy over by showing him outsmart the whole JL" moment, which was then immediately followed by him getting beat by a bullwhip to the junk from freaking Catwoman. Cat. Woman.
there was no depth to his character, no real plot or plan of any sort to speak of on his part beyond "embarrass the Justice League", no character motivation...nothing. Miorrison's Kool-Aid Brigade just jumped on him immediately as "OMG WOWZERS this guy is the greatest creation ever b/c G-Moz is so rad!!!!!!!!" but in the end, the super-villain had no clothes, and was there solely to look kewl in one issue only to job out in the very next.
at least characters like the Joker, Lex, Two-Face, etc have some hook to them, something in their character beyond powers or a suit, that makes them interesting. they may lose, but they're still interesting to read about, and have staying power beyond one or two appearances. Prometheus has none of that, and never did. he's a classic 90s "all attitude, no dimension" cipher of a jobber.
This statement is more based on a personal bias of the character rather than actual facts. I get the fact that you don't like the character and that's fine by me but I don't agree with what you said-and it's nothing to do with me being a so called Morrison fanboy which I am not.
And what you said about him having no motivation is so far off-His motivation was to stick it to the forces of justice after his parents were killed which mirrored what happened to Bruce when he was kid, which is why he was intended to be an anti-Batman character. You would have had me with your argument if you were to talk about the shitty Gotham Knights arcs where the character got turned into Hush's bitch or him getting owned by the likes of Alfred, Green Arrow or even Robin in Teen Titans( Which was retconned into it all being his teenage sidekick Chad). The main problem with Prometheus is the same problem Bane faced is that he had potential to be a good character but got fucked up by bad writing.
