I guess I expressed myself poorly. I meant to say Flash Man and Time Man have similar frameworks on a lore level: in Mega Man 2 Wily created robots that are arguably enhanced designs over Light's originals.
I think Flash Man is pretty broken as is, at least when playing against him as a bot, but that's likely because he can spam FS a lot as a bot
Oh I see what you want to say about the character lore.
The problem with bot Flash Man is the infinite ammo. The Flash Stopper use up every single bit of ammo and can't regenerate till the effect still active. This mean you can not shot during Flash Stopper. But the bot has no ammo at all. If it stop the time, Flash Man still able to shot because the unlimited ammo. This is really overpower as an AI.
Maybe if we limit the shot itself. For example Flash Man can shot only once during the Flash Stopper, or shot out less in his burst during that time. Oh and of course it must be accurate to the NES boss: so if a stopped enemy receive a hit, the stopper effect will immediately disabled.
But this is just my opinion. For some reason I like to see some Flash Stopper + Shot combo in a balanced way.
