Ruby

So! Thought it would be a good idea to list all of the Pokemon Ruby has on hand, complete with pictures.

Nana, the Mightyena.
Coco, the Delcatty.
Zuzu, the Swampert.
Popo, the Castform.
Mimi, the Milotic.
Ruru, the Kirlia.

All of them are used mostly for contests, but are very able fighters since Ruby is a talented Pokemon battler. Even though he hides it most of the time.
