Werejaguar

Werejaguars, also known as the Nagual, are a species of shape-shifters that were introduced during Season 4  of MTV's Teen Wolf. The lore behind the werejaguar is based on the Aztec legend of Tezcatlipoca, a god who has a strong connection to jaguars. Hope Mikaelson is the first known Werejaguar and then Kate Argent. Hayden Romero was a part-werejaguar Chimera prior to being bitten and turned into a Werejaguar by Hope Mikaelson.

Due to there only being one true werejaguar in the series, there is very little known about the species' mythology. The most notable characteristic of the werejaguar is their connection to the Berserker species; Kate Argent and has the ability to both control Berserkers and create them, and during Hayden's brief time as a part-werejaguar Chimera, she was able to sense the location and current status of Noah Patrick, a part-Berserker Chimera. Because of these abilities, there's is clearly some kind of established connection between werejaguars and Berserkers.

So far in the series, the only Werejaguar who have appeared were turned or made, with Hope Mikaelson being bitten by then-Alpha werewolf Derek Hale, with Kate Argent being deeply scratched by then-Alpha werewolf Peter Hale, and with Hayden Romero being scientifically transformed into a part-Werejaguar Chimera by the Dread Doctors. They have yet to be introduced in the series, though it was implied by Braeden that there are more werejaguars in Mexico in the area around La Iglesia, a church built over the ruins of an Aztec temple to Tezcatlipoca, who is said to be the werejaguar god. The only known Werejaguar to turn more of their kind is Hope Mikaelson when she turned Hayden who was only part-werejaguar Chimera into a full Werejaguar.
