Harmir

Harmir is a Froakie who got lost somehow from his home reigon of Kalos, but made it back and is now improving his skills as a Greninja.

Appearance
No different than the average Greninja, but has a wetsuit he can don in the underwater base owned by Croc.

Personality
Harmir is very serious, sometimes well-mannered, and somewhat fancy. He can be easily distraught and annoyed, and when he gets sad he tends to get extremely sad. The idiocy of several Pokémon he's met has made him jaded and less tolerant, and he relishes the opportunity to teach others a lesson in battle.

Finn
His only remaining friend, the Chespin from Kalos that was lost alongside him. He is often annoyed at his lack of knowledge and had decided with his old Frogadier body, he didn't need Finn's help anymore.

Franny
The Fennekin from Kalos that was lost alongside him, he admired and respected Franny and called her Francine. When she abandoned them because she was happy not being in Kalos, he was hurt, but ultimately let her pursue her own goals. Now he can barely stand her constant requests to be put on a pedestal, compared to him or Finn.

Croc
The two have been at odds and ends ever since Harmir was a Frogadier, but he eventually, after much persistance, agreed to join his "CKREW" of underwater and Soaked Pokémon, hoping that he would be fairly judged there. Harmir isn't extremely fond of Croc, but can tolerate him for now. The CKREW fell apart, so they don't really talk anymore, but Harmir may decide to visit Croc again.
