Onslaught & Apocalypse vs. Thanos

Thanos gets 2 days prep.

The team only has 1.

Who gets owned?

Team get man handled.

team get beat down.

Depends which Onslaught.
If it's full power, (Nate+X+M+FR) then Thanos would need to get IG to own him.

I say team wins.

By the potential: Team

By the feats... Thanos pimpslap to the end of the universe.
Hell, Onslaught got owned by Hulk, and Apocalypse never really win against the X-Men. While Thanos take out Silver Surfer like Chuck Norris would do to an arrogant kid.
