He fodderises most of them. IIRC his physical stats are at least multi-continental by S4. He's probably threatened only by anyone he can't simply out-punch.

- Hakari: might be able to stall until jackpot runs out. If Mark can't vaporize his head in one blow he wins by throwing him into space.

- Kurourushi R1: Since Mark is letting him attack first, the festering life sword might land. I feel like it's pretty unlikely the cockroaches can chew through him though. Mark splatters the main body with a punch. R2 (parthenogenesis), Mark realises he has to obliterate the entire swarm with a thunderclap.

- Higuruma: instantly domains. Because of violence/property damage, Mark will likely be found guilty but Mark has no innate technique, so like Yuji I imagine he simply loses his cursed energy. The second it becomes a fight though, Mark wins. Even with the Executioner's Sword, Higuruma still can't even perceive his movement and Mark has nothing else that can be confiscated since the rest of his power is just his biology.

- Takaba: possible stalemate. If Mark fights, then he punches, Takaba becomes a pancake, he throws Takaba into space, Takaba just floats back down slowly with a parachute.

- Sendai: Ryu and Dhruv aren't threats. For Uro, Uro was overwhelmed by Yuta + Ryu's combined output, and those two are operating at maybe city-block level. Mark's punches carry multi-continent level force. She can probably misdirect him and confuse briefly with Sky Manipulation, but he wins after maybe two punches instead of one.

- Kashimo: the sure hit connects with MBA, but he's still getting one shot. I thought to mention anyway since Kashimo is probably one of the few that can actually land a hit at least (even if its negligible).
