Oh I forgot to mention there are two rounds.
Round 1- random encounter between teams involving time portals or what have you.
Round 2- the beyond team have a weeks prep
With prep I figured with prep and whatever funding he can get from blight that shriek could do some damage like he did in the show. With the building he used like a pitch fork and sent out disrupting waves making animals go nuts and disrupting human speech causing havoc. Even did that deafening sonic blast. Could use that to their advantage against their enemies with super sensory.
Blight heats up and goes nuclear and can kill batman by proximity while he is immune to melee going critical.
Inque in her nature is a pain in the ass to fight. VS wonder woman? Suffocating superman or batman? Whatever. She's lethal and at least getting their attention until the other two get into it.
I gave it a little thought lol.
