10 Most Powerful Supervillains You’ve Never Heard Of
5. Mikaboshi
When you're the God of not just evil itself, but also chaos and the stars, it seems only fair to expect at least one cool moment in comics per year. Although Mikaboshi gets one of these - in the Chaos War series, where we get to see just how badass the deity is - after this, they literally never get to feature even vaguely in comics ever again, because apparently we're not allowed nice things.
Admittedly, Mikaboshi was sent into another universe at the end of the Chaos War, but in a franchise where death doesn't stop people from coming back, being yeeted into another universe is a pretty small obstacle to overcome, meaning Marvel could bring back the Chaos King whenever their hearts desired.
While the reason for Mikaboshi not being used recently is possibly out of writer's fears of coming off as disrespectful - as the god is a legitimate deity from the Shinto religion - depicting him fighting Spider-Man doesn't appear to be inherently rude, so it's really prime time to see the big bad back in a new series.
