I.N.S.T.I.G.A.T.O.R. (an acronym for the Integrated Neural System Techno-Intelligence Gyroscopic Atomic Tactical Organic Robot) is a former student of the H.I.V.E. Academy and an enemy of the Teen Titans.
The exact origin of I.N.S.T.I.G.A.T.O.R. is unclear, but at some point he was recruited as a student into the H.I.V.E. Academy. Cyborg later infiltrated the institute to discern the latest plans of its then-current headmaster, Brother Blood; in the wake of the resulting conflict the academy was destroyed and most of its students, including I.N.S.T.I.G.A.T.O.R., went freelance.
At some later point of time, I.N.S.T.I.G.A.T.O.R. was recruited into the Brotherhood of Evil and participated, along with Steamroller, in the capture of Thunder, in which they succeeded. When the Titans mounted a final assault on the Brotherhood's base, I.N.S.T.I.G.A.T.O.R. fought against Hot Spot and when the firy Titan launched a flame blast, the mechanical villain was defeated and ended up flash-frozen along with the majority of the assembled villains.
Powers and abilities
I.N.S.T.I.G.A.T.O.R. appears to be either a merging of human and robot or a sentient robot; his exact nature remains unexplained. Owing to his robotic systems, he possesses superhuman strength and resilience. Since he is a robot, he may possess some amount of knowledge in robotics and technology. His exact fighting prowess wasn't seen, but when capturing Thunder, he was able to stretch his arm.

- I.N.S.T.I.G.A.T.O.R. is similar to the Marvel Comics supervillain, MODOK, as both have enlarged heads housed in a robotic exterior and both have names that are acronyms, MODOK's being "Mental Organism Designed Only For Killing".
- He was one of the few H.I.V.E. Academy students that wasn't a part of the H.I.V.E. Five at some point.
- Although he has not spoken in the cartoon, and although no one is credited for voicing him, he has yelled once (while capturing Thunder). Even though he was seen talking to his friends in "Deception", his voice is never heard.
- In the episode "Deception", I.N.S.T.I.G.A.T.O.R. was about 10 feet tall, but in "Calling All Titans!", when he was sent to capture Thunder, he was the same size as Steamroller (both were about 20 feet tall) and the giant bricked wall they broke through. Oddly enough, after Thunder blasted them, Steamroller was taller than I.N.S.T.I.G.A.T.O.R. So this could possibly be that I.N.S.T.I.G.A.T.O.R. had a "growth spurt". Either that, or it was an accidental writing error.
- In the Teen Titans Go! issue 11, the blue robots are similar to I.N.S.T.I.G.A.T.O.R.
