Snowstalker

Snowstalker is an animal in the Beast Wars portion of the Generation 1 continuity family

The majestic predatory cat Snowstalker once prowled the distant frozen lands and mountaintops of prehistoric Earth. Like all members of her species she was typically a loner, but a chance encounter with the Maximals would change her life... and also prematurely end it.

Snowstalker was the animal template scanned by Tigatron's stasis pod. With his memory circuits damaged, Tigatron felt like he was more animal than robot, and he chose to stay in the wild alongside Snowstalker. The two roamed and hunted together, apparently forming a strong pair bond--Optimus Primal was aware of how special Snowstalker was to Tigatron. By a cruel twist of fate, in a heated battle with the Predacons an errant shot from Tigatron caused a rockslide on the mountain Snowstalker was climbing, and she was crushed to death. In his grief, Tigatron marked her final resting place with a crude representation of her made out of stones. At the time he swore he would never be able to bury another friend and thus could no longer participate in combat of any kind, though he soon had to reconsider.
