Gladiator kills all of them before they know the match has begun. He is thousands of times faster and plenty strong enough that they are going to take damage from each of the thousands of punches he is hitting them with.
Agreed with all the above. Gladiator rips through them like a hot knife through butter before they're aware the fight has started.
Even if you allow TP, it wouldn't make a difference, because J'onn would never get a chance to use it. And eliminating BFR is meaningless here, since none of the participants can D-dump or time-dump and a space-toss just means waiting for the tossee to come back (which they all could).
So yeah.
