>>44232582>>44232588Fighting Pokémon usually get a lot of Normal (which you can't really count), Dark, Rock, some Ground, Steel, Poison, Psychic and some rare elemental moves that are mostly classified as "punch" or "kick". Some rare exceptions get a few, more "radically elemental" moves, like Machamp with Fire Blast, for example. So those are the types we expect a Fighting type to be able to use.
And what do you know, Grapploct is a good example for this. Going off its move selection on showdown, we see that it learns 16 Fighting, 19 Normal, 5 Dark, 1 Psychic, 1 Ice, 3 Ground and 1 Bug move. And - not to forget - 10 Water moves. On a Pokémon that is not a Water type. The only other Pokémon where we expect similar cases of a high concentration of moves of an unrelated elemental type are Normal or Dragon types, and pseudos like Dragonite, who gets a lot of non-stab Water (10), Ice (7), Electric (6) and Fire (6) moves. It also evolves from Dragonair, who has been used as an example for a Pokémon that has a case for Water type before.
Not even Stunfisk and Eelektross, two other Pokémon who are very popular examples for not-Water aquatic Pokémon, learn as many Water moves as Grapploct. Eelektross gets less Water (2) than Dragon (4) or Poison (5) moves, and Stunfisk learns 7.
Grapploct is pretty much a Water type. It even gets the otherwise highly exclusive Soak, which literally turns the target into one. Clobbopus, Azurill and Eiscue are the only other non-Water types who learn this move.
