Sub-Zero Bros

Sub-Zero is the younger brother of Sub-Zero, who died and became Noob Saibot. When Sub-Zero tied, Sub-Zero changed his name from Tundra and took up his brother's mantle of Sub-Zero.

Sub-Zero is the worst competitor in Heir to the Throne history. Sub-Zero isn't very good, either.

2-Player Duos
The Sub-Zeroes were entered into the round 3 match between Scorpion & Smoke and the Super Mario Bros, where they were eliminated.
