I spent a lot of time here at Camp Secret when I was just about your age and do you know what ..... It pretty much .... Ruined my life.
~ Jack Shepard.

Jack Shepard (aka "Captain Zoom" or "Zoom") is a superhero that appeared in the 2006 film ZOOM of the same name. He is the leader of the original Zenith Team along with his older brother Connor Shepard (Concussion). He is also the leader of the new Zenith Team, which consists of Princess, Mega Boy, Houdini, and Wonder.

Jack is portrayed by Tim Allen, who also portrays Tim Taylor in Home Improvement, Scott Calvin in the Santa Clause film series, Dave Douglas in The Shaggy Dog, and Mike Baxter in Last Man Standing, and voices Buzz Lightyear in the Toy Story film series.


During his prime, Jack Shepard and his older brother Connor Shepard led the original Zenith Team that consisted of Ace, Marksman, and Daravia. As a team, they saved countless lives, but eventually, the team's leading scientist Dr. Grant had both Jack and Connor exposed to an experimental substance known as Gamma-13. The substance made Jack faster and stronger, but Connor was turned evil due to the effects of the substance. Jack eventually battled his brother and sent him to another dimension, leading him to lose his powers, his brother, and his team.

30 years later

30 years after the events led him to lose his powers, his brother, and his team. Jack became a very bitter man who worked at a small auto repair shop. It wasn't long before Dr. Grant and his assistant Marsha Holloway came and took him to Area 52 in order to train a new Zenith Team. The team composed of Cindy Collins, Tucker Williams, Dylan West, and Summer Jones, and the military offered him a payment of $500,000 in order to train the team in order to prepare them for Connor's return. At first, when Jack starts training them, he is not putting his heart into his work.

Jack eventually realizes he needs to face the facts and start really teaching the new team. He eventually improved his method of teaching and as a result, succeeded in his job. Eventually though, the military plans to expose the team with enough Gamma-13 to take down Jack's brother. This all changed when Marsha helped the team escape and use the FE-12 Flying Saucer to get to the location of the portal that would return Connor to Earth. Upon Connor's arrival, Jack greeted him, however, Connor attacked him and realized that Jack had lost his powers. Afterwards, the military attempts to use the sonic net Dr. Grant had designed, but Connor deflected it towards Cindy. Before it hit Cindy, Jack's powers return and he saved her before she was killed.

With his powers fully restored, Jack returned to Area 52, suited up, and returned to the site as quick as possible. Now being called Zoom once more; he started creating a vortex while the other members of the new Zenith Team got Connor in the middle of the vortex. Jack managed to actually close the vortex this time and managed to get his brother to produce a sonic blast that knocked him out of his evil ways. Three months later, Jack continued working with his brother and the new Zenith Team.

Powers & Abilities

Super Speed: Zoom was born with the natural ability to propel himself at superhuman speed. According to Marsha Holloway, Zoom's natural speed was superior to that of Superman, Quicksilver, and the Flash all combined. When he lost his ability to run that fast, he still had a remnants of his power left, mostly assisting him as a human blender.

They made him a special suit out of polycarbonate silicon in order to keep him from vibrating out of his clothes. When his powers did return and he ran to suit up at Area 52, Zoom actually comedically tripped through the desert and rolled several meters before coming to a halt and then continued on his way.

Personality & Traits

In his youth, Jack was known to have been a very brave and true superhero, defending justice at every turn. After losing his powers, brother, and team. Jack became a very bitter and sarcastic man and demonstrated this to many people, including the new Zenith Team at first. Despite everything though, Jack maintained a nice guy attitude that resurfaced when he started putting more heart into his work. Once he became Zoom again, he regained what it meant to be a superhero. Apparently, when both he and Connor were growing up, Jack hated being called "Jackie" by his brother.
