Jack is the main protagonist and player character in the videogame MadWorld.
"A MadWorld... I'll fit right in."
A mechanic and former marine with his primary weapon as a retractable chainsaw equipped to his right arm. Jack is the protagonist and player character of MadWorld, and is voiced by Steven Blum. His other known history is that it was erased prior to DeathWatch's 2019 opening and that no specifics are given beyond nothing is certain and is definitely not as seen in the game or cut scenes.
Jack is the star of MadWorld, the man with the chainsaw on his arm, the cigarette in his mouth, and the biggest swagger to hit Jefferson Island in years. Jack arrives on the scene in Varrigan City without a sponsor, a reputation, and with no obvious reason for being there, aside from the hundred-million-dollar prize that’s up for grabs.
Of course, that’s what he wants them to think. The people in the studio, the folks watching at home, even Agent XIII…none of them knows about the voice in his ear, Amala. Nor does she know about the voices in his head. Jack’s mysterious past and his motivation for entering the DeathWatch Games is revealed in due time—but only to those who live to hear the tale.

"I don't help people. I kill them."
"Amala, I've got a chainsaw on my arm. I'll be fine."
"Let the games begin."
"...and now I found out it's all for the money. I feel so dirty."
"Who wants a piece of the Jack!"
"You're a fucking joke!"
- He competed and won in the 2001 DeathWatch Games. As the winner, he is considered by DeathWatch as the current "reigning champion." In the beginning of the last area, Jack hints at how he has "three games under the belt." It can be deduced that he has competed and won two other times aside from the 2001 games.
- It is unknown how Jack got a chainsaw attatched to his arm. One explanation could be that he lost his original arm in a previous Deathwatch game. Another could be that the chainsaw arm is a gadget placed on his actual arm to be used as a weapon in the DeathWatch games. He had the chainsaw attached to his arm before meeting Agent 13, so it is not a gift.
- One of Jack's finishers is homage to Sub-Zero's Spine Rip Fatality from Mortal Kombat, another ultra-violent game.
- He, along with the Black Baron, Rinrin, Mathilda, and Big Bull appear as playable characters in another beat-em-up game similar to MadWorld, Anarchy Reigns.
- Jacks chainsaw bears a striking resemblance to the chainsaw of Ash Williams from the Evil Dead series.
