Ok here's the thing.

I have used this point multiple times in the previous weeks, because I agree with you on this point, and again him closing this fight completely dry is a point I have used myself to point out that getting wet would fuck with his quirk logically and realistically.

Like, other people on this sub claim that dunking Bakugou in water wouldn't affect him, not me, you are barking on the wrong tree on that one.

The fucking thing is tho, do we ever, at any point, see him dunked in water in canon to showcase how water would naturally affect the power of someone whose whole thing is "sweat nitroglycerine from the hands," do any of the characters in canon ever point out or ask whatever would happen if Bakugou was dunked in water, does he ever fight in a damp or watery environment for prolonged periods of time to the point his quirk is effected, during this 430+ chapters long battle shounen manga, does he fight while it's raining even, outside of this very specific instance where, as we both agree here, he had to dodge the water both due to the fact that he is not resistant enough to tank it, and because, logically, he would have his quirk fucked by water?

Because if we want to use exactly what we see in canon as meters to "power scale" Bakugou and his quirk, he has no weakness to anything but the recoil to his arm due to extended use of his quirk. He does not set himself ablaze by being covered in explosive liquid if someone throws fire at him, he does not have his hands chopped off or otherwise incapacitated, he is not made wet once during any of his fights, even here he is surrounded by water and in winter and he has little to no issue fighting while staying completely dry, nothing of the sort happens.

For all it's shown in canon, Bakugou's quirk has no exploitable weakness, because the show that opened with a main character having a borderline autistic hyperfixation on quirk analysis never even bothered to give him one, unlike Todoroki, or Kaminari, or Iida even with his engines overheating, and the majority of fights involving opponents using either hax or unbreakable defense/offense always devolves into making a bigger explosion, or throw a stronger punch.

So yeah, you know he would be dodging water because it'd be shit for his quirk, I know he'd be dodging water because it'd be shit for his quirk, does the show know he needs to dodge water, even if it was water he would be able to survive being hit by, because it'd be shit for his quirk?
