So its like A Certain Magical Index(kinda)? Sounds legit. In that case make sure his ability is the weakest or something or maybe its strong but he never uses it like ever or serves as comic relief mostly. Kinda like a non OP Gildarts.

In my series fights are about honor and if someone else's honor is at stake then the MC does not interfere unless he is entrusted with protecting that person's honor. Only during a world crisis is the honor rule more flexible. All the characters gain the strength to destroy a planet by themselves at the middle of the main saga, albeit with varying means but they still can't defeat some of the enemies, that is cause they are incompatible and literally can't counter said enemy's ability. In which case they lose for real instead of gaining plot-armor. The fights are less about overpowering the opponent but more about tactics. The cast changes their way of thinking depending on the opponent. However the MC being an MC is the one who changes his tactics the most.

Also the arguments during a fight also play a role. Its not nakama power, he simply finds a flaw in the enemies way of thinking and elaborates on it, causing the enemy to lose focus for a split second, allowing a good blow to land. But enemies differ and some have a flawless ideology or can't be reasoned with, these fall due to other factors like getting cocky at the last second or being betrayed by their own bodies and minds or simply for not paying attention to their environment or forgetting a concept in Physics.
