Hunter-type Pokémon are incredibly powerful due to their typing, regardless of the Pokémon all Pokémon old and new benefit from the Hunter-Type. The Hunter Type specializes in Attack and Speed although often has poor Special Defenses. They do well against 21 of the 42 types (including themselves) in Generation 10 making them very broken and therefore banned as moves in general as well as Pokemon in tournaments. They resist 17 types, are resisted by 10 types and weak to only 8 types. Hunter Types are also resistant to Sleep and have most moves attached to Sleep under their type.
As of Generation 10, there are 51 Hunter-Type Pokemon making them uncommon overall although common in comparison to other Fanon Types. Approximately 65% of Hunter-Types originate from Generations 1, 2, 3, 4, 5, 6 and 10.
Hunter-type Pokemon consist of mostly animals which hunt and are predators. Hunter type more commonly appears in Fully-evolved Pokemon as well as occasionally replacing "lesser types". Of the re-typing for Generations 1-6 only Spearow, Scyther and Sneasel are Base form Pokemon which can evolve that are Hunter Types and Spearow is the only one of these that wasn't originally a fully evolved Pokemon.
4 of the Starter Pokemon are part Hunter in their final forms, originally Feraligatr and Typhlosion were also going to be part of that group however due to the issues arising of two starters in the same generation sharing a type they were both scrapped from the group. Of these starters Water-types appear more commonly with Samurott and Greninja being Hunter-type.
