One thing I like about Teba is that he has absolutely no connection to Revali. Like Sidon? Mipha's younger brother. Yunobo? Directly descended from Daruk. Riju? Descended from Urbosa. But Teba? One angry Rito who decided to fight Vah Medoh with only a bow and rage
Honestly? Who would be better suited to carry on Revali’s legacy than someone who decides to confront Vah Medoh out of spite
