Not even close. Bang is only good for fighting humanoids.
Which most of the MA executives are?
If you’re going by the typical definition of a humanoid, then
Gouketsu
Nyan
Homeless Emperor
The Two Ninjas
Gums
Fuhrer Ugly
Black Sperm/Golden Sperm
Are all humanoid opponents. Only Rover and EC are non humanoid Executives (coincidentally the only MA executives Bang has been placed up against, probably because Murata/ONE knew that the only way to have real tension in a Bang fight is to put him up against non-human opponents). And I guess ENW but that thing almost lost to base child emperor.
So Bang would fare just fine against the majority of Cadres/Cadre levek
For example Child Emperor can defeat anyone Bang can, but there are monsters Bang can't defeat that Child Emperor would be able to. By default there is no real reason to place Bang higher than Child Emperor.
You are grossly overrating child emperor, he would stand next to 0 chance against Gouketsu and Elder Centipede, EC of whom Bang looked strong AF against but I’ll address that down below:
Bang is absolutely no match for most high level dragons. He had no shot against Elder Centipede despite Bomb and Genos fighting with him, it also doesn't help that he's shown age.
Bang stood no chance against elder centipede? We reading the same manga? Bang and Bomb Shattered EC into smithereens, and Bang wasn’t even using his strongest technique which is the abandonment.
I’m not saying he would win, but Bang looked far better against EC than you give him credit for.
You know who would actually stand 0 chance against Elder Centipede? Child Emperor. He is a brain and nothing more.
There are like 7 monsters from the association who would defeat him. He's not carrying the hero association when he's that far down the ladder. Tatsumaki is absolutely needed here.
Okay, let’s look at Bang against the Cadres:
bang vs Fuhrer: lol
Bang vs Gums: lol
Bang vs Homeless Emperor: given that Bang can react to Rover’s light blasts, he shouldn’t have much trouble against HE. HE is essentially Rover lite but with much worse durability.
Bang vs ENW: a weird matchup so Bang probably loses
Bang vs EC: EC extreme diff
Bang vs Nyan: Bang high diff
Bang vs Rover: Rover
Bang vs Black Sperm: Black Sperm
Bang vs Gouketsu: either way
So I count only 5 monsters that if we’re generous, can high or extreme diff him. And frankly that’s just assuming Gums and Fuhrer who bang one shot, are just that much weaker than the rest.
You’re downplaying bang hard bro lol. In one of the audiobooks, Darkshine states that he stands no chance against Bang, and Darkshine is a mid/high dragon himself.
