Jaguar first appeared as a major character in Episode 2 - Jungle Area of the Kemono Friends anime.
Jaguar is best described as a reliable and helpful Friend. She willingly provides river crossing services of her own accord. In Episode 3 - Mountain, along with Asian Small-Clawed Otter she was also shown waiting near the bus until Kaban and Serval return with the battery. In season finale, Jaguar showed a genuine concern to Kaban's safety.
Role in the Plot
Jaguar gives Otter, Kaban, and Serval a ride to Unin Bridge where the Japari Bus is located. They find the back portion of the bus but no driver compartment. Boss leads the group over to the other side of the river where they find the front part of the Japari Bus. Kaban and Serval initially have Jaguar try and carry the boat over on her raft, which promptly begins to sink due to the weight of the bus. After several other failed attempts, Kaban enlists Jaguar to help her build the makeshift bridge that Serval then uses to jump across the river with the driver's seat.
Within her appearances, Jaguar is sometimes shown standing around with Otter. Otter and Jaguar at least are close enough to know each other's schedules.
In the season finale, Moose tried to challenge a confused Jaguar to a competition of physical strength.
