Nature: Quiet
Good endurance

Haejigoku, the only Pokemon Aero would outwardly call a friend, has psychogenic mutism brought on by past trauma. Very few Pokemon know the extent of what happened to him, Aero being one of those rare few due to their unlikely bond. While this has left him unable to speak, Haejigoku is still a perfectly capable team member with a quick wit, able to get the Ghostly Gang out of some sticky situations. Nobody's really sure what his opinions on the others are though, as he is fairly difficult to read in general.

Main four moves:
Leaf Blade
Growth
Sludge Bomb
Sleep Powder
Capable of using most other moves from movepool
