|Occupation||The Company's agent|
The Constrictor was a Company agent who confronted Echo.
The Constrictor accompanies his partner, Agent Howard, in a mission to retrieve Echo DeMille. They approach Echo after witnessing him use his ability to ward off a dog that was chasing him. When Echo attempts to flee, the Constrictor wraps himself around Echo, squeezing him tighter and tighter. However, Echo is able to break free by using his ability on both Company agents.
The Constrictor then gets up and grabs his partner's gun as Echo starts running. He fires two shots toward Echo, but Echo keeps running. The Constrictor then shoots his partner in the head, and calls Bob on his cell phone. He tells Bob that Howard is dead, and that the situation is worse than they thought. He then looks at his phone to view a picture of Echo embracing a woman, commenting "It's a shame... She's so pretty". The Constrictor then walks in the direction Echo ran.
The Constrictor sneaks into Echo's house and takes Echo's girlfriend Gina as a hostage. When Echo locates them, he uses his ability to force the Constrictor to set Gina free. Afterwards, the Constrictor seems powerless to stop Echo from taking him by the throat and directing a concentrated sound into his right ear. The sound passes through the Constrictor's head, spattering blood out from his left ear onto a nearby wall and killing him.
The Constrictor has the ability to mimic a constricting snake. He can literally squeeze the life out of people quickly, or slowly, at his preference; and can numb people with his touch.
- According to NBC.com's character reference, the Constrictor has an identical twin and is part of a gender neutral clan that is highly protective of one another.
