Any idea why Bug Bite doesn’t get a boost from Strong Jaw? Considering the multitude of real life bugs with devastating bites, it seems only natural that there should be Bug-types with Strong Jaw that uses Bug Bite as its primary attack… How cool would a Bug/Fire ant Pokémon with Strong Jaw-boosted Bug Bite and Fire Fang be?!
Well, I expect it’s for much the same reason as Sucker Punch isn’t boosted by Iron Fist – in Japanese the move’s name doesn’t literally refer to a bite. Bulbapedia translates the move’s name – むしくい – as “Bug Bite,” but when I plug those characters into Google Translate it offers me either “Furious” or “Moth” so who knows. What we call a bug “bite” in English is very often not a literal bite but more of a stinging or piercing action so I could very easily see this being one that doesn’t apply across languages (in French the move is called Piqûre – “Sting”).
EDIT: Of course it is true that the move’s effect (consuming an opponent’s berry) points to a literal “bite” of some description, but it would also be fair to note that a lot of insects don’t really have “jaws” in the vertebrate sense.
