Augmented Version [Futuristic settings]
Augmentations: Neural Uplink, Cloaking Augment
Backstory: Talii and the rest of his pack were involved in a civil war where they came from, and therefore gained plenty of combat experience. Unfortunately, Talii is the only member of the pack that survived said war (as far as he knows, anyway). He suffers from a psychological issue in which he sometimes "sees" his pack members. He has occasionally been seen having a lively conversation with the air, claiming he is talking with one of his pack members. Aside from that, he is a rather friendly person.
Biological Version [Modern or futuristic settings]
Has the natural ability to turn invisible.
Backstory: Talii was happy with his packmates as they hunted, as was their job in the tribe. That is, until he discovered his ability to seemingly vanish, and the rest of his pack did as well. He was abandoned by his tribe shortly afterward
