Jackknife is the secondary antagonist in the 2007 American adult-animated series Superjail! and an Inmate at SuperJail.

He was voiced by the series' creator Kristy Karacas, though he never actually speaks a word of English, communicating only through grunts and screams.

Biography[]

Past[]

Jackknife appears to have gotten his criminal ways from his father who is also shown to have had a total disrespect for others' lives. This included his own son's happiness which was displayed in the form of him selling his toys in order to get booze. The recollection of this memory causes Jackknife so much pain that he sobs at the thought, and pushes a boy away from his toys so he can play with them.

Superjail![]

In the show's present Jackknife is a low-level criminal who appears in the openings of most episodes committing crimes before getting captured and beaten up by Jailbot, where his subsequent journey back to Superjail makes up the opening credits sequence. He is often seen escaping the jail during the murder sequences in the first season and periodically throughout the next two seasons. He never speaks and communicates only by way of animalistic grunts and shrieks.

Jared has labeled him to be Superjail's most vile inmate due to his upbringing and near lack of any form of morality. In the episode Oedipus Mess, Jackknife is revealed to have fathered a son with one of Ultra-Prison's inmates. Having recognized the child as his, Jackknife escaped while the Warden created 10,000 clones of Jackknife that run amok worldwide until all but the original are killed off.

Personality[]

Jackknife is depicted as a violent, greedy, short-tempered and misogynistic low-level criminal and pervert with a lack of apparent morals, judgment and sophistication. His various poorly planned criminal activities are seen at the beginning of each episode and inevitably end up drawing Jailbot's attention and getting Jackknife severely beaten and hauled back to Superjail.

Despite this however, Jackknife has still been able to not only survive all of the riots and massive chaotic events that happen in Superjail but also escape several times with ease whereas only a handful of other inmates have been able to do this, showing that Jackknife is a gifted criminal.

Although his criminal nature is generally a constant, in the episode "Oedipus Mess", the Doctor states that he has "a microscopic quotient of selfless love". This is later showcased when, in the same episode, Jackknife presumably crafted a hanging mobile for his genetic son and taught him to tunnel through walls.

Trivia[]

  • In the season 3 premiere, Stingstress, a female version of Jackknife, is seen causing chaos at a male strip club before being hauled to the UltraPrison, implying that he has a sister or a wife.
  • Although it looked like that Jackknife was killed by Hunter in the episode "Hotchick", it is possible that the victim in question was actually a similar-looking inmate. This is because the victim's hair was down instead of straight up and the camera angle may have zoomed into Jackknife to confuse viewers.
  • In contrast to most episodes, he is not seen escaping in "Combaticus", "Don't Be a Negaton", "Dream Machine" and "Mayhem Donor", and only does so off-screen each time. He was also sent to a regular prison in the episode "Time Police, Part Two" which he later escaped from.
    • In total, whether it be on-screen or off-screen, Jackknife has escaped Superjail at least twenty-nine times.
  • In the episode "Ghosts", Jackknife is seen making up with his father (suggesting that he has since passed) before they started to attack each other. Back in the space between crossing over they can still be seen fighting by stabbing each other. This marks the first time Jackknife has actually died even though he was still technically alive because he is not actually seen dead as a corpse.
  • Jackknife's prisoner ID in his first appearance is "52A2L20RE".
  • The only two episodes Jackknife never appears in is the season two episode "The Budding of the Warbuxx" and the season three episode "Stingstress".
  • During the early stages of development for Superjail!, the little girl from the episode "Cancer" was planned to eventually be revealed to be Jackknife's daughter. One of Adult Swim's "Bumps" even shows artwork of them together.
