Team: Thundra, She-Hulk, Sif
Alone: Wonder Woman.
Right people, not sure how fair this is, but WW beats so many A-leaguers that I wondered how she would fare against 3 other warrior females.
All in their strongest incarnations, Team get's 1 hour prep, WW get's 30 minutes.
Fight takes place on the rainbow bridge, start 30ft away. The bridge here is 10x wider and 3x longer.
