After Luffy saved Koby and defeated the Alvida Pirates. Koby became a Marine officer who trained together with Helmeppo under Vice Admiral Garp's supervision. His appearance and personality had changed completely when you last saw him. Under Garp's instruction, Koby's timidity has been replaced with confidence, although he remains polite and apologetic if he feels he has done something overly ambitious. He continues to be an emotional, compassionate person who can easily be driven to tears.
