The Utroms are an alien race from Dimension X. Though once unified in the name of peace and prosperity, their unity was shattered by a scientist named Kraang who conquered and enslaved the majority of them to his will. The remainder who resisted renamed themselves the Utrom Tribe and worked in secret to try and stop the newly dubbed Kraang faction from its goals of war and conquest
- The main Utrom tribe members are named after a certain chess piece: Queen, Rook, Bishop, Knight and Pawn. Only missing the King.
- Kraang Subprime was known as Knight before he joined the Kraang.
