Rockruff looks cute, but is really gutsy: No matter how much it gets beaten it'll keep standing up to its enemies until it beats them. It greets people by pressing the rocks attached to its neck against them, which is kind of painful for the recipient. Its body is small, but it hides a secret.
Rockruff are very friendly Pokemon but their personalities become rougher as they grow. Howling at dusk is evidence their evolution is near. When evolving, they will seperate from the trainer and return once their evolution is complete.
- The starters and Rockruff share a yet unconfirmed secret.
