This Haunter is a Ghost/Poison-type Pokémon used by Morty, the Ecruteak Gym Leader.
It battled Ash's Cyndaquil and Noctowl. Haunter was able to use its hands independently from the rest of its body since its hands were not physically linked to the rest of it. It was able to reach into Cyndaquil's Smokescreen and pull it out before using its Lick. It also attempted to use this strategy against Noctowl after defeating Cyndaquil. Haunter was eventually knocked out by Noctowl's newly learned Confusion.
