My character's issues he contends with in no particular order:
1) A relationship with his
Imzadi (an original character of my creation, a human female) which ended seven years earlier. She worried over the distance between them. He truly loved her, and she was a crewmember on
USS Voyager's journey into the Delta Quadrant. He had no idea as to her fate, but hadn't given up hope that she still survived, but the not knowing whether
Imzadi lived or died played havoc with his mind. Even if they had 'broken up'/given each other space the inescapable fact that he still loves her is still there.
2) Survival Guilt. Before entering the Starfleet Asymmetric Warfare Group he'd served as an Explosive Ordnance Disposal (EOD) operative (hence his reasons for recruitment to that force) doing demining operations in the DMZ. He and his team defuzed over 450 separate Cardassian and Maquis improvised explosive devices within their first forty days in the DMZ. He had lost two of his teammates to devices, to include the youngest of his team members over that timeframe. He carries the empathic echoes of both deaths on his conscience.
3) The Dominion War. While having no qualms of killing enemy soldiers that threatened his life when he carried out the various special operations missions he still carries those empathic echoes of deaths of friend and foe, ranging from the shock of a Cardassian soldier he killed with a photon grenade on a mission to the prolonged agony of a severely wounded and dying Federation soldier that died on an operating table beside him when he was wounded on assignment.
4)
Imzadi's return. As I have both him and his
Imzadi serving together on Deep Space Nine after
Voyager's return, he's going to have to contend with how the past seven years changed both of them in profound ways. While
Imzadi's tour on Voyager was no picnic, she had been spared the horrors of the Dominion War and in the case of my male lead, perilous behind the lines missions.
Imzadi is going to find a greatly careworn, and haunted individual standing before her after her return from the Delta quadrant and reconciling that with the romantic, idealistic man that had first called her
Imzadi can make for some interesting storytelling.
Just because the character is 1/4 Betazoid, doesn't mean he would have weaker abilities. The only 1/4 betazoid I remmeber seein in an episode of ST was in TNG's S3 episode "The Price".
It might even be possible for a 1/4 Betazoid to have full telepathic abilites, empathic abilites or no abilites.
Well, I remember Deanna Troi, who's half Betazoid, seeming to have weaker telepathic/empathic abilities than her mother due to her having been half human.
