This is it, Jack. I waited thirty years for this.
~ Concussion to Captain Zoom.

Connor Shepard (A.K.A "Concussion") is a superhero that appeared in the 2006 film Zoom. He is the older brother of Jack Shepard (Captain Zoom), former leader of the original Zenith Team, and now leader of the new Zenith Team. After being exposed to Gamma 14, Connor turned evil and killed his teammates, excluding his brother. Connor was then accidently sent to another dimension, but promised to return to kill his brother. Returning thirty years later, Connor was turned back to normal by his brother, and befriended the new superheroes.

He is portrayed by Air Bud star Kevin Zegers.


During his prime; Connor Shepard was one of the leading Zenith Team members alongside his younger brother Jack Shephard. He and the team saved countless lives and fought off many threats to the world, however, this all changed when Dr. Grant subjected both Connor and Jack to an experimental substance called Gamma 13. This caused Connor to turn evil and kill Marksman, Daravia, and Ace, leaving only Jack to combat him. After Jack tried to use a mega vortex to snap Connor out of his evil ways; he accidentally sent him to another dimension.

30 Years Later

30 year later, Connor remained trapped in the dimension he was sent to, however, he was working his way back home in order to obtain his revenge on Jack for betraying him. This led Dr. Grant to report this to General Larraby, who ordered the immediate reinstatement of Jack in order to train a new team. Jack wasn't made aware that Connor was alive until Dylan West's mind sight powers revealed Larraby's true intentions were to use the new team in order to distract Connor while Grant used his sonic net to trap the former superhero.

When the new Zenith Team arrived to combat Connor, Jack was there to greet Connor upon his arrival. Eventually, they both sparked a brief argument before Connor shot Jack in the air several times, which helped him realize that his brother had lost his powers. After almost killing Jack, Mr. Pibb managed to distract him while the Zenith Team prepared for their confrontation with Connor. After the sonic net was fired, Connor re-directed the net towards Cindy Collins, who was then saved by Jack, who has regained his powers.

After Jack returned, Connor was knocked within a vortex caused by Jack and, after several attempts to break out, Connor emitted a concussive blast in hopes he would escape. This, however, backfired when the vortex actually sent the blast at Connor, knocking him out of his evil ways. After returning to normal; he was greeted by the new Zenith Team and became part of the team once more.

Powers & Abilities

Concussion is known to have the power to emit powerful concussive sonic blasts at his enemies. A single blast is capable of knocking down a whole platoon of soldiers and send an individual several feet in the air. He emits such blasts just by punching at the air and his blasts are clearly visible to the naked eye. He can even make smaller ones as well.

Another power that was possible ability that he possessed was the natural ability to not age as fast as an average human; however that could have been either because of the dimension he was in or because of the Gamma 13 he was exposed to 30 years prior to the events in the film.

Personality & Traits

Connor was known to be just as brave hearted and true as his younger brother. He is known to have possessed the same desire to bring bad guys to justice and stop them at every twist and turn. This eventually changed, however, when he was exposed to Gamma 13, which caused him to become selfish and vengeful as well as a cold blooded killer. He did, however, also put the lives of the new team in danger as well. After being snapped out of it by the mega vortex created by Jack, Connor regained his old personality.
