Brennan Mulwray is a fictional character on the television series Mutant X. He is portrayed by Victor Webster.


Brennan Mulwray is one of the genetically engineered superhumans called "New Mutants". Brennan was the son of a Vietnam War fighter pilot who was imprisoned and killed after his plane was shot down behind enemy lines. Brennan and his stepfather never got along. He had begun using his abilities to boost cars by the time he was 10 years old. He and his buddy Cole Thatcher pulled crazy stunts like racing stolen cars on icy lakes; Brennan almost died once when his car went through the ice. In high school, faced with the court-appointed choice between juvenile detention and counseling, he chose to see psychologist Dr. Victor Palance, the first person he trusted enough to tell about his New Mutant abilities. After high school, Brennan lived in a small apartment with his high school sweetheart, Becky Dolan, until she conned him out of money and left him. Brennan continued his life of petty crime and grand theft auto. He felt guilty after recommending his friend Dennis "Denny" Logan for a bank job which turned out to be a set-up, getting Denny thrown into prison. Brennan had just moved his gang up to armed bank robbery when he encountered Emma deLauro running from The GSA. While attempting to protect her, he was captured by GS Agent Frank Thorne. Brennan chose to join Mutant X after they rescued him from Genomex's employ. In later seasons of the show he was also given the ability for low grade flight (high jumps/hover). Brennan was a former thief but later became a member of the benevolent organization Mutant X. Brennan also has a romantic history with fellow New Mutant Shalimar Fox that developed in later seasons.


Brennan is a reader of Walt Whitman's poetry books which helps him relax. He also bounces tennis balls to help him think and spends about $50 on fresh, hot, gourmet coffee. He is a big sucker for fast muscle cars like Cutlasses, Camaros and Ferraris. He is also a motorcyclist as seen in an episode of season 2 where he is cleaning his motorcycle. He somewhat plays the electric guitar. Brennan does not like missing the previews when he is at the movies. He also gets a hot temper like in the final season opener where he gets infuriated with Eckhart about the disappearance of Adam. Brennan is also helpful to the team. Brennan's biggest fear is having his powers used against him.


Brennan is an Elemental, which means he can project or channel electrical energy from his hands.

Electrokinesis: He can manipulate electrons in his body and other objects to create intense electrical charges. Brennan can throw Tesla coils from his fingers, allowing him to jump-start cars and cardiac arrests, open electronic locks, and electrocute enemies. Brennan needs a period of rest between voltage uses, and cannot use his abilities when he gets wet, lest he short out or electrocute himself. Brennan can be grounded by wrapping his arms in chains or holding something that's touching the ground.

  • Electronic Disruption: Brennan can use his powers to disturb electronic-based machinery, open electronic locks and electrocute computer systems. He can also restart inactive machinery by charging it with definite amount of electricity.
  • Reactive Electro-Jet Propulsion: After further mutation, he can create reactive electric jets to make high leaps and even levitate and fly.


  • Water: Water is Brennan's main primary weakness as it shorts him out and he cannot use his powers when he is wet or he electrocutes himself.


  • Martial Arts: Like all the other members of the team, Brennan is a skilled martial artist.
  • Thievery: Before he was a member of Mutant X, Brenna was a skilled thief. He was able to rob places like banks with his criminal associates.


Shalimar: Well, I guess it is true.

Brennan: What's that?

Shalimar: The bigger they are, the faster they run.

Brennan: That's because he knows I can light him up like a Christmas tree.
