I understand they're designed that way - but that doesn't mean the design make sense. Someone design this
thing, too. Even if they're designed to hunt in a particular way - why on earth would a monster that has claws the size if its face suplex its foes? It wouldn't, it would cut it up.
If you read the entire thing, I reference all recent starter Pokémon, it isn't specific to Incineroar. I feel the same way about Decidueye and Primarina. I didn't like any of this generation's starters as Pokémon. Their concepts could be worked into a design with a bit more subtlety. Let me put it like this: if Jigglypuff was a recent Pokémon, they'd probably be wearing a tutu since they attack by singing.
There's quite a few Pokémon with exeggerated concepts like those. One of those, Clawitzer, is one of my favorites of all time. It has this insane hand cannon they'd logically use for hunting, but it also works as a monster species.
