About
Lupine is very smart, calculated and observant. He enjoys intelligent conversations and solving puzzles, and is very fascinated by fear and suffering. That, together with his lack of morality, make him an excellent interrogator. He masks his manipulative nature with charm and eloquence, but doesn't shy away from showing his ugly side if necessary. He has a habit of being handsy with others, having little to no respect for their personal space. This behavior isn't always intentional; he's just very physical by nature, experiencing things through touch. Being an outcast in his past, Lupine has a hard time maintaining relationships with others. He is independent, but also loyal to those who deserve it.

Backstory
Lupine is half-Cybertronian half-Insecticon. He was never treated as an equal on Cybertron and therefore found himself hiding in the shadows, minding his own business. He studied Cybertronian anatomy on his own and started to provide others with illegal upgrades and body modifications. Most parts he salvaged from the Gladiator fights and re-used them in his work. His personal goal was to build a body and give it life, but stealing a Spark for his creation turned out to be much more complicated than he'd believed. Once the Autobot authorities found out about his illegal actions, they arrested Lupine and locked him up. Ironically, one of the arresting officers had been his customer, but no punishment were given to them.

Lupine stayed in prison for some years, slowly sinking deeper into the darkness of his own mind. He wanted vengeance on his capturers, and surprisingly got his wishes fullfilled, once the prison was invaded during the Decepticon Rebellion. He joined the Cons right after being freed.

During the war, he serves as the Second in Command of the Torture & Interrogation Force on battleship Nemesis. His commanding officer is Ripmaw, with whom he remains friends even after the war. On Nemesis, he also meets and becomes close friends with Supercell, eventually enstablishing a romantic relationship with him. Like-minded in many ways, their relationship lasts for a good amount of years. Lupine has never trusted anyone else as deeply as Cell.

Daughter
Lupine's life takes a turn, when he ends up carrying a Sparkling after a quick love affair with another Con, Shadowraker. Out of curiosity, Lupine decides to keep the Sparkling, even though Shadow doesn't want to stick around to raise it. Lupine quickly grows fond of his new daughter, Flytrap. In a way, he gains a new purpose in life; taking care of her. Their bond is unbreakable and stays that way well into Fly's adulthood.
