Tybe was a minor character in the fourth season. He is portrayed by actor Darcy Laurie and appears only in "Heavy Lies the Crown".
Tybe was an Ice Nation chief. After Farm Station crashed within Ice Nation territory, Tybe's group fought against them. Tybe was the one who killed Monty Green's father. His group also enslaved various people, including other Grounders and at least one Farm Station survivor, Riley. Some point after Pike's group moved to Arkadia, Tybe's group took over the station.
In Heavy Lies the Crown, Bellamy Blake, Harper McIntyre, Nathan Miller, Bryan and Monty travel to Farm Station to retrieve a hydro generator. Tybe allows the group to take the hydro generator but refuses to let them near the slaves. The group staged a rescue mission for the slaves, blowing up the generator to kill most of the Ice Nation slavers. Tybe survived but was attacked by the group and pinned down. Monty released the slaves from their chains, allowing them to beat Tybe to death.
