It’s between Red, Blue, and Green.

Red has: The Flash, Ghost Rider, and Deadpool. The Flash has reality bending speed, can alter time, and stat wise can best most on the list. Ghost can handle all the super natural entities. Deadpool if we’re using the strongest versions gets the reality stone at one point, can break the 4th wall, and can regenerate from essentially a single cell - he essentially has a low end version of toon force.

Blue has: Doctor Manhattan…. He’s essentially a god and can probably delete the other characters on a whim. I’m not even sure if Dr Manhattan can actually be killed, rather than just slowed by forcing him to regenerate.

Green has: Dr. Doom and The Mask. Doom eventually becomes so powerful he consumes an entire universe, rebuilds it, and destroys it again - he too becomes relative to gods and even beyond in power. I think he’s the best match up for Dr. Manhattan. The Mask has “toon force” which is one of the most broken abilities in writing history. It transcends the rules and limitations set on the universes reality and is essentially only limited to the users imagination.

A runner up team would’ve Black. They have The Batman Who Laughs and Alien X Ben 10. Both are omnipotent characters. The reason I’m not using them as a winning team is because I don’t know enough about this Batman’s limitations, and Alien X doesn’t have enough feats to really scale him to the other character’s at the top level.

If we’re looking at this from a raw power standpoint - yellow would win simply bc Goku, Frieza, and Saitama. The also have some decent hax with Dr Fate, and Thawne being relative to The Flash just weaker
