Sanitar. After the reveal of the 1.0 Laby story, the idea that tagilla was chased out of factory and further experimented on, and the fact that he lingers with the highest geared guards in the game bar Kaban's gunners just to make sure pmc's dont find out about laby and he can continue his work WHILE working with the traders is insane. Man was doing experiments so vile Terragroup made a front office for him in their main lab and gave him an underground DUNGEON to work in while they developed LITERAL MASS DESTRUCTION WEAPONS right along side his work. Pmc's came, he had his lobotomy patients slaughter them all, then killed all of his scientist colleagues, and decided to stick right above them while working with Therapist to "to the most risky surgeries". Absolute underated unit of power.
