Tsukimi

Dr. Tsukimi (ツキミ博士) is an old man who appears in Enel's cover story. He created the four wingless Spaceys on Machine Island. He has a passion for moon watching, as his name implies. One day, he saw a giant explosion, which led him to die from shock while choking on the dumpling. His Spaceys put him in his coffin and cried. After his burial, his Spaceys swore revenge on whatever made the explosion on the moon that killed their creator.
