So we have a few ground rules you have the same amount of prep they had aka apparently none. You can have any 4 powers you want but nothing to powerful that would easily sway the fight in your favor like omnipotence.
By the way I’m choosing Super-Strength Invincibility Flight and Omega Beams
Density manipulation, Flight, Telekinesis, Superhuman physical condition. (Aka better green ghost) Hold em back with the help of the others, phase into his skull and then turn my fist as dense as the core of a neutron star.
