Dr. Martin Brenner is the director of Hawkins National Laboratory and quickly appears as an antagonist in Stranger Things. He is in charge of the program conducting experiments on Eleven, using his telekinetic and telepathic abilities to carry out espionage missions in particular.Brenner appears to be manipulative and ruthless. He is very strict with Eleven since he took her away as a baby, but represents the father figure and lets the girl call him daddy. It is rather difficult to know if Martin Brenner has emotional feelings for her, or if the latter is just a means to feed the excessive ambitions of this mad scientist.Shortly after the incident that freed the Demogorgon, Martin Brenner shows himself ready to do anything to cover up the affair and find Eleven who escaped from the laboratory. He and his team leave the bodies of innocent people behind and do not hesitate to cover up evidence or create false evidence. He will even go so far as to create a fictitious corpse of Will Byers to make it look like he drowned and stop the police investigation led by Chief Hopper.Martin Brenner's POP action figure is like the character in Stranger Things: a relatively old, cold and ruthless man. His grey hair is perfectly coiffed and Brenner wears a perfectly tailored grey suit. He stands must, tying the knot of his tie as if he were in the middle of a reflection with his frowning eyebrows.Funko has pushed the details to the point of depicting the wrinkles on Martin Brenner's forehead and the dark circles under his eyes, trusting the character with the stern look he gets when he's upset?
