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
The powers I’d choose are: Spider-sense, energy projection/manipulation, phasing, and telekinesis. I’m going pretty risky without super strength or super durability, however, spider-sense and phasing will keep me out of danger, while I can blast him with energy beams and stop him from hitting my teammates using telekinesis. With my powers he wouldn’t be able to touch me.
