First walks out of a store with new clothes First is then hit with a stray bullet from a nearby thief damaging his shirt.
Later that day…
A criminal was found severely injured and encased in a metal contraption made of 5 cars 2 lamp posts and a nearby food truck Authority’s are currently investigating the motive…
I have no words to demonstrate the huge gap int term of power level between one punch man and First. At least for now, we witnessed that First was able to tear through metal almost as if it was paper, and the full amount of First’s capabilities are yet to be discovered, but One punch man could punch an entire planet out of existence with ease, and his power might be infinite. First has yet to demonstrate power to such an extent, First is NOT weak but cannot compete with One Punch Man even with a similar power-set. This is why I say that First is underpowered compared to One Punch Man.

Offensively no First wouldn’t stand up to him. But First’s growth potential is a combination of capacity and efficiency of energy conversion. First is very proficient in kinetic energy conversion… most common within lab tests running jumping running bullets explosives. So at their maximum it is possible to counter punch with almost equal force received IF the initial attack doesn’t obliterate First.
That said. I’ve always found it a bad idea to try to compete with Anime characters in terms of power levels. SO many world breakers.
There are a few power sets that could beat Saitama. The one I could think of off hand from this WIP would be Silic. Their body can become insubstantial so any pure kinetic force is inconsequential. even if hit Silic will reform them self. Where the real danger comes from is when Silic turns their body insubstantial and decides it would be fun to fly into your respiratory system and carve you into a bunch of leaky cold cuts from the inside out. Anyone up for sandwiches?
