Chainsaw Man

I don't know, it seems to me you are making an already overpowered villain even more powerful. As if it was a demon king in a sword & sorcery fantasy series.

He felt like he was supposed to be the series big bad to me. Or at least, the long-term goal.

What's the point of making the devils based on a very particular thing if the plot doesn't stick to it?

Dunno. But what part of blood is about making weapons like hammers and swords? But that's still a thing Power does.

That's far more interesting than it being able to do everything by itself, in addition to the huge destructive power.

He's also be working in conjunction with other devils. There's already been 3 working with him we know of. Like you said earlier, there could be some kind of Secrets Devil or something.

I feel like the devils that had been powered up by pieces of the Gun Devil weren't working with the Gun Devil. I would go as far as saying they were random devils the Gun Devil powered up for no particular reason or for experimentation. The Gun Devil is so strong it can afford to do it. If it can track its own body parts later, like you suggested, then it could have also counted on those devils being defeated by the agency, which would allow it to see where those body parts end up to.
