Zar was born in the Sarpeidon Ice Age, and was the son of Zarabeth and Spock - making him one-quarter Vulcan. Despite being one a quarter Vulcan, his appearance was distinctly Vulcanoid, with a marked resemblance to Spock. His eyes were grey, and he had dark hair. His hearing was exceptional, but although he had the Vulcan inner eyelid, his vision was barely outside human range. His blood type was different than anything the Doctor had ever seen before - a greenish-grey mix. He had spectacular muscle tone from living and hunting in the wilderness, with wide shoulders. McCoy made an observation while Zar was in the Enterprise that at a proper weight, Zar would easily mass more than Spock. Zar also had large keloid scars from an attack by a Vitha - one running along the right forearm from his wrist to his elbow, and another from the outside of his right thigh running nearly to his knee. The only noticable features that belonged to his mother were his jaw and mouth.
Zar was highly intelligent and had amazing telepathic abilities, being able to project strong emotions such as hunger or fear onto other beings. Doctor McCoy also found that when pinching a nerve on Zar's arm, they could both feel the pain. Zar also experienced premonitions, and could pick up on the feelings of those around him.

Zar lived with his mother Zarabeth until she died after falling into a crevasse when he was 19 summers old. Unable to properly bury the body, he placed it underneath an ice sheet in a cave. From that time until he was 25 summers old he lived in complete solitude. To fend off the cold when in the wilderness, he wore a face shield, hood, and furs. Underneath this he wore a leather tunic, under which his emaciation was severe (despite his muscle tone, strength, and endurance). When Zar had 15 summers, he had studied himself in a mirror that his mother had, and then he painted his face on the cave wall along with hunting pictures. After his mother's death, he would sometimes talk to to this face.
He would hunt animals for food, the only real nourishment being meat in the ice age. Because of his ability to mentally project intense feelings, he was able to stop an animal for long enough to capture and kill it.
When Zarabeth was living, Zar found that he could tell what his mother was thinking - but was told that it was not polite to do so without permission. Zarabeth also taught him to read, and would often correct his grammar - before she was exiled to Sarpeidon, she was a teacher. Zarabeth also spoke fondly of Spock to Zar, telling him that he was always loving and caring.
There will be a post about Zar's life on the Enterprise, and afterwards.
