Celestials, Braniac, Cyborg-Superman vs Watchers, X-man, Magneto

Everyone is in Character
No prep
fight takes place on Taa-II (Galactus space ship)
Team 2 gets prep time

Team One wins easily, a small portion of the Celestial Host decimates them.

I bet a single Celestial could take them all on, and not even the most powerful.

this ends celestials vs watchers. and the rest dead
