Darkseid, at least for me, wasn't powerful enough. I feel like Darkseid showing up is the only time when powerhouses like Superman and MMH should be jobbing, because Darkseid is kicking their asses, probably with little to no effort at all. I also felt like the whole Superman going all out moment when Darkseid returned was a little underwhelming. I mean, sure, it was awesome and all, but I expected more planetary level damage from a pissed off Superman. Maybe he was still holding back some, but still.
Darkseid. Not only is he capable of beating the ever-loving-shit out of Superman, but he's no slouch in the intellectual department either. Possibly even smarter than Lex. Plus, like a previous poster said, an entire planets worth of resources. He's basically the complete opposite of Superman.
Random thought: Why don't celebrities just say omnipotence when asked what power they would have? That's what I'd do, since it basically encompasses all other powers, right? Idk, I'm pretty sleep deprived right now, so...
Anyway, Zod and his army have appeared in the MCU and set up all the World Engines. Basically the same scenario as Man of Steel, but instead of Superman, different characters from Marvel will face him.
Scenario 1: Vs Avengers
Scenario 2: Vs F4 universe. Silver Surfer included.
Scneario 3: Vs X-men universe. This means all movies, including First Class.
Scenario 4: Kryptonian Army vs Chitauri and Loki
Scenario 5: All Marvel movies combined. This means Spider-Man, Daredevil, etc.
No prep for Marvel, Kryptonian army is fully adapted to Earth's atmosphere just as Superman was. How does this play out ?
I'd use them to figure out how to keep them forever. I would then find out how to boost my power to Kal Kent levels so not only do I have insane Superman powers, but I also have 5th dimensional imp powers. Only then would I be satisfied, until I got bored... *evil grin*
