No The Gladiators powers is a mixture between his nature pysical abilities, strength speed etc... but he has a mental power that allows him to do whatever he sets his mind too, so his strength speed and stuff is all flexible because of this, which is really good, he can grow in a fight which makes him very handy to have around on a leesh 😉
Gladiator's confidence is what fuels him, he knows he can win, so his mental ability grows his pysical body limits to the length in witch it needs to be to win the fight.
Gladiator V.s. Superman 😉
