Misty is the protagonist of the Emerald LP. She is the most cynical and prone to anger of all of Chorocojo's characters, and ends up hating the entire region of Hoenn rather quickly. Appears to be somehow related or friends with Roxy, judging by how she appears and kills Gatorface at the end of the Crystal LP. Her rival could not be named (and so was called Brendan) but she considers him to be a huge jackass. He briefly gained some credibility after giving her HM Fly, but quickly lost it.
Roxy is the protagonist of the Crystal LP. She loves cute things and suffers heavily from Cuteness Proximity. She gets very serious if cute Pokémon are threatened. Her rival hated weak Pokémon and only used strong ones for battling, and so he was jokingly named Smogon.
Foxy is the protagonist of the Quartz LP. She seems very nice and is the cousin of Roxy from the Crystal LP.She eventually gets sent to a mental hospital because Misty shoved a TM into her Ludicolo's body, and the TM didn't work, but the Ludicolo tried the TM again, leading to Foxy going insane. (The LP was actually done by Zorak, but Chorocojo contributed heavily.)
Lady is the protagonist of the Platinum LP. She is sarcastic and wisecracking, in contrast to her hyperactive rival Jorge. She is often played as the Only Sane Man with the exception of Professor Rowan, who she regards as the best professor ever.
