Even when he first came on the scene he made an impression.  He kidnaps Ares' son, brainwashes him, conquers Olympus, and kills Zeus, arguably Marvel's second most prominent Skyfather after Odin.  I became a fan when he was simply believed to be the Japanese god of evil, but now his attack on Olympus seems pretty damn minor in comparison to what he's doing now.  I admit I'm having a hard time comprehending just how powerful he's become and what he's accomplished.  Not since Thanos obtained the Infinity Gauntlet has someone so thoroughly threatened the Marvel Universe.  Pretty impressive for a character who's been around less than five years. 

Writers are just running out of good ideas for universal calamities. Mikaboshi is a lazy idea. He went from skyfather to equal to Eternity in the blink of an eye.  
 
I think it's fairly pointless to have beings like Eternity, Infinity, Death and Oblivion (originally it was only Eternity and Death), since finding characters equal or greater in power is now so common.

I think the better villain for something like Chaos War would have been the Dragon of the Moon.

" Nekron rose pretty quickly. "

Anti-Monitor anyone?
