From Star Trek: Theurgy Wiki
Scosche Bellde'side was a stowaway who was killed in action. Before his death, Scosche Bellde'side briefly aided in the opposition against the parasites that compromised Starfleet Command in the end of the 24th century.
Born to Kortpoh of Narendra III, a disgraced Klingon, and Betana Bellde'side, a Betazoid botanist, on Tau Ceti III, Scosche, Sco to his friends, was raised for the first few years of his life with both parents, until his father regained his honor amongst the Klingons and returned to Narendra. His mother, who, while devastated by the loss of his father, strove to provide a loving environment for her son. She returned to Betazed, where Scosche became an official citizen. While not having the full telepathy of a Betazoid, he did have the expected empathy of a half-Betazoid, helping him to fit in on the planet. As he grew older, he became more and more attracted to the physical sports, though he long denied his Klingon violent tendencies. He learned to channel all his energy into gymnastics, developing a long, lean body over what might have been expected of a Klingon, the large-muscled, heavy bodied appearance most found amongst his father's side of his lineage. His mother's career bloomed, as well, and the attention garnered her trickled down to him, earning him a spot on the Betazoid team to the Earth-sponsored galactic Olympics at the age of 14, the youngest age anyone from any planet could be admitted. At the age of 18, he'd eared his first gold medal and gained fame on multiple planets.
On what he'd considered to be a flattering, if unauthorized, tour of the USS Theurgy by a very attractive petty officer, whom he'd hoped to bed, he found himself trapped aboard when the ship came under fire and escaped into warp. The woman he'd come aboard with had hidden him, worried about what might happen to him, and herself, should it be discovered she'd brought him aboard without permission. For months now, he'd hidden away in an isolated cargo hold, the petty officer bringing him meals. To keep himself from losing his mind, he focused on his training, keeping himself at his peak physical condition. With nothing but time on his hands, he'd wrangled together a practice beam, along with flying rings, and a pair of uneven bars, the room she'd secured him in just barely large enough to accommodate his routine if he used one at a time.
There had been several times where he'd been knocked about, what he assumed were battles the ship had been in. And, days ago, he'd gone through the weirdest invasion of his empathic abilities. For hours, or days, he lost track of time, he'd felt nothing but the urge to copulate with someone, anyone, but without someone with him or near him, he simply focused on his exercises, driving himself to exhaustion. Now, however, it had been several days since his petty officer had been to see him, the supplies she'd left him starting to run thin. He would have to venture out and risk being discovered.
As with most athletes, Scosche has an air of confidence about him, sometimes termed as arrogance. Having achieved at such a young age what others older have attempted, however, gives him a certain feeling of accomplishment, a sense that his confidence is well-deserved and not misplaced. He sees himself as a competitor, a champion and not as his father would have liked, a warrior. The abandonment of his father early in his life left him with a patriarchal anger toward his Klingon side, and though he has certainly used his natural talents to his advantage, he still resents his father's absence.
His attitude toward sexual relations is typical of most Betazoids, open and uninhibited, though his religious beliefs are more scientific, as inherited from his biologist mother and the conflicting views of his Klingon father.
