Captain Grime is a towering green toad and former commander of Toad Tower, feared across Amphibia for his immense strength, booming voice, and commanding presence. A seasoned warrior and brilliant military strategist, he believes strength, discipline, and loyalty are earned through hardship. Although gruff, intimidating, and often blunt, Grime possesses a surprisingly dry sense of humor and develops a genuine fatherly bond with Sasha Waybright, training her into a formidable fighter and supporting her even when she chooses a different path. Once driven by ambition to overthrow the kingdom, Grime eventually abandons conquest in favor of protecting Amphibia alongside Sasha and his allies against King Andrias and the Core. Beneath his hardened exterior lies an honorable soldier who deeply values loyalty, courage, and the people he calls friends.
