Teba is a character from The Legend of Zelda: Breath of the Wild. He is a Rito warrior and the husband of Saki. Teba also has a son named Tulin who he wishes to raise up as a warrior equal to Revali's skill.
For the moment Teba's role in the Zelda series is only composed of informations with an unconfirmed timeline placement and should stay this way until we have a definitive answer, so please don't add any information regarding the timeline placement without OFFICIAL confirmation, thanks.
Before his meeting with Link, Teba tried to disable the Divine Beast Vah Medoh.After Link speaks with him and explains that he also want to disable the Divine Beast, Teba requires him to complete a training exercise at the Flight Range to prove he is strong enough to fight in the air since he is an Hylian and as such is not very suited for that kind of fighting.After the exercise has been completed, the two of them head into the sky to fight Vah Medoh. During the battle, Teba assists Link by getting the cannons of the Divine Beast to focus on him, giving Link an opportunity to shoot them down. Once the cannons have been taken out, Teba reveals that he was injured during the fight with Vah Medoh, and thus must return to the Flight Range to rest. He leaves Link to enter the Divine Beast on his own, wishing him luck in the trials waiting for him inside. When Link gets back to Rito Village after freeing Revali's soul, Teba thanks him for his efforts and hard work. He then leaves to take his son out to the Flight Range.
