really like @abfgmsw’s idea! You could get really creative with that.
Other than that, maybe different orgins of powers…like meta humans vs. aliens vs. magic based powers, etc(I know there are more but I just woke up and can’t think lol). And aliens I should say are purely just aliens to EARTH so green lantern…lobo…all kryptonians, starfire, etc.
And if you really wanna make it engaging, have multiple rounds with different conditions favoring one of the contestants cuz we would want it so its not predictable considering we got some heavy hitters on DC comics. So like for instance:
Aquaman vs. black canary
round 1: on the shore of a beach
round 2: open courtyard in a city or something away from water
round 3: idk something else even lol
But obviously you guys would have to play with it:) love this idea tho, can’t wait to see what you all decide on!!
