Here, i will name all his combat feats. taking out firestorm with his breath, defeating the metalman crew who are meta levelers (while depowered), tackle all star superman to the ground, stop krypto from attacking him, punching kosmos. those are all the fighting feats in favor of kal kent. now here comes the other side of him losing. getting destroyed and completely wrecked by the elseman to the point he was on the ground crying, one shotted by ultraman using heat vision on him, beat down by batman 1 million without even being able to lay a hand on him. all in all, kal kent IMO and based on the feats is just another version of average sups with several extra abilities. he is imune to magic thanks to him 5IMP blood but it still doesnt mean he has the power to hurt RKT.
