Alternates

Alternates, initially known as Coldsnaps, and sometimes called Sideline Characters are characters who are not necessarily initially in an Heir to the Throne tournament that gain entry when competitors in other matches have matches that end in a tie.

Ice Age
Perhaps the most high-profile use of an Alternate was when Gill tied with Mr Freeze in the first round of the Ice Age tournament. Both characters' names were thrown into the list of Alternates, and they were replaced by Frost Walrus. Frost Walrus, in turn, defeated Sub-Zero, who was a heavy favorite to win the tournament. Meanwhile, in round 2, Gill was randomly pulled as a replacement for the tie between Spheal and Vanilla Ice, and then went on to win the entire tournament.

2-Player Duos
In this tournament, run by Brandon A. Mayo, a third team was mentioned in each match, described as being Sideline Characters; if Team A and Team B tied, there would be a Triple-Threat rematch, now involving Team C. In the finals of the tournament, FIVE teams got involved after Sonic and Tails and Earthworm Jim and Snott tied.
