Battle Scenario: Takes place on an empty alternate reality Earth. Both teams are transported to separate staging areas with no knowledge of what's going on. Each team gets 10 minutes and are told they will have to fight another team, but that's it. They have no way to gain any information about the other team until the 10 minutes are up (not even with Cosmic Awareness or magic). After 10 minutes they are informed that the other team is located 1km away. In order to make it back to their respective Earth's they must win.
Win by KO, death, or permanent incapacitation.
Which team makes it back home?
