Thomas Tracer is an ordinary modern boy who is a host to a dragon named Viper. They have a symbiotic mutualistic relationship, but that dosen't mean they always agree. Thomas tends to be sarcastic, but with the dragon as a part of him, to those who don't know him well, he is cold-hearted and emotionless. He is very good with mechanics, and can fix and use almost any mechanical utility.
Viper shares his draconic abilities with Thomas, allowing him to time travel and whatnot. Viper has a very definite mission, to protect the timeline while looking for a way home. He urges Thomas to follow that mission, and Thomas does so, not always willingly. Thomas and Viper can seperate forms, but not for long, as the atmosphere and magic-less enviroment will eventually turn Viper to stone. Thomas is normally in a half-dragon, half-human form, he is mostly human, but he has a few scales on his legs and arms, and half of his face is covered in scales, as well as draconic horns protruding from his head. He wears an arcane cape (a.k.a, part tech, part magic.) and hood that hides his horns and most of his scales. He has an arcane bow that also functions for melee purposes.
He can travel to alternate dimensions and universes, and he will do anything to protect the timeline. It is his first priority, and will destroy anyway to assure that it is safe.
He tends to wear modern clothing, except for his cape. He has special technology kind of like cloaking, but instead, people just dont notice or percieve him.
He is a master at making technological and magical weaponry, and sometimes takes up assassination missions.
