I love Pokemon!!

Hal has paradoxically the most and fewest pokemon of the members of the Justice League. He has several extraterrestrial convergent pokemon, but none he's allowed to use on earth.

We'll be covering only pokemon known on earth, even if they're extraterrestrial.

Wingman: Hal's shiny Skarmory. This one was given to him by his father. After his father's death, his mother never wanted to see this pokemon again in her presence or even spoken about. Has gone everywhere with Hal. Though not a true Green Lantern Corps. member, when out of the ball, Hal constructs him a suit. Even remained by Hal's side during his possession by the fear entity Paralax, trying to free him.

Flyboy: A shiny Braviary that Hal caught during his service in the air force.

Jet: Vikavolt

Minior (Green Core): a common minior that Hal caught in space.

Mouth: Squawkabilly (Green)

Beheeyem: Caught in space. Joined Hal of its own volition.

Softy: Clefable

His Legendary Ally is a pokemon that's been on Oa since the Guardians and the Battery have. In this world, the Emotional spectrum entities are all legendary pokemon.
