The Travelers (Worm) vs the League of Villains (MHA)
All For One wants the Travelers' powers, so he hires the League to take them down.
The Travelers' combat squad is Trickster, Perdition, Sundancer, Ballistic, and Genesis. The League consists of Shigaraki, Kurogiri, Dabi, Toga, Twice, Spinner, and Mr. Compress (as of season 4).
Neither side is aiming to kill, the Travelers are too soft for that, and the League needs them alive for the boss to steal their powers, but they're willing to do so if need be.
If Travelers stomp, League goes through their season 5 power-ups (Shigaraki and Toga go through their quirk awakenings, and Twice embraces the full potential of his power). If League stomps, Travelers now have the standard brute and mover rating all the characters in the MHAverse seem to have (there is no way Stain should be capable of those acrobatics...). Does that make a difference?
