You have inspired me to post my characters as well.
Name: Viktor
Tektek:

Species: Felis Sapien
Age: In his 30's, not quite sure the exact age yet.
Bio: Viktor is one of the only two whom were able to take the many Human language manuals aboard Red Dwarf, and actually read them the way humans read them (with his eyes, not his nose.) He became interested in the engineering textbooks, and became an expert at repairing all sorts of broken machines. His most recent achievements include repairing the light beam of a hologram that was on board a deserted space cruise ship, and rewiring the circuitry to the motherboard of a basic food-generator.
Name: Aura
Tektek:

Species: Felis Sapien
Age: Same as Viktor, she's his twin.
Bio: Aura is the second of the Cat race to figure out how to read with one's eyes instead of their nose. Like Viktor, she became obsessed with learning human knowledge, but chose to read medical textbooks and understand how to use human medicine and medical equipment. Her knowledge alone has prolonged the lives of many of her fellow cats.
Name: Felicia Harris
Tektek:

Classification: Ex-human hologram
Former Occupation: Travel Planner for the Space Corps Cruise Ship, the Trailblazer
Current Occupation: Assistant Engineer
Age of Death: Mid 20's.
Days Since Death: A century.
Bio: Felicia is the hologram that was brought back online by Viktor. She was amazed to find out that the Felis Sapien found a way to keep her online without depending on her former ship, the Trailblazer's power supplies. Ever since, she's sought to repay this "life debt" by reading hologramatic copies of Viktor's engineering texts, and then giving him directions as to what methods and tools he has to use. Catching onto to the mechanical textbooks was easy for Felicia, as she had a bright mind. She sometimes laments how she could have been an engineer, if only her family hadn't struggled with poverty.
