Mi-kun (ミーくん) is a small white cat-like companion in Uchuu Senkan Yamato. He is not a major combatant or crew member, but serves as a cute mascot-like presence that adds warmth and humor to the story. In the series, Mi-kun is associated with Sasha’s pet and appears as a gentle, affectionate animal character rather than a human fighter. His role is mainly supportive and symbolic, helping to soften the tone amid the show’s serious space warfare and dramatic stakes.
