A teenage thug who left a 16-year-old boy disabled after smashing his skull with a homemade club in an attack inspired by TV's The Walking Dead has been jailed.

John Callis-Woolsey, 18, bludgeoned his victim with the sinister-looking baseball bat which was daubed with the word "Lucille" and had sharp nails protruding from it.

After launching the brutal assault the teenager then celebrated by doing the "Floss" dance from the popular computer game Fortnite.

The victim's mom is now warning of the impact violent games and TV programs can have on youngsters after Callis-Woolsey was jailed for eight years on Thursday, Feb. 20.

Her son was left hospitalized for nine months and now requires full time care due to a lifelong brain injury which has left him being only able to walk with the aid of a frame.

His mother said:

"This was a mindless and unprovoked act of extreme violence. I was shocked when I saw the hideous looking weapon that was used."

"I would like the producers and creators of such programs to know the influence the content has on immature minds."

"The assault has changed our lives forever, my son is serving a life sentence and doctors have advised that he will remain disabled for the rest of his life."

Derby Crown Court was told police were called to reports of an assault in Middleton-by-Wirksworth, Derbyshire, England, on November 13, 2018.

Detective Constable Derek Ellis said after the case:

"This was an act of extreme violence which was planned, orchestrated and carried out by a teenager for a somewhat trivial matter."

"His actions that night have dramatically altered the course of two young and bright promising lives, one of which was his own."

"The victim and his immediate family have had to come to terms with the consequences of that night."

"Their fight, spirit, and support for each other has been nothing short of admirable."

In The Walking Dead, the character Negan, played by actor Jeffrey Dean Morgan, uses a baseball bat wrapped in barbed wire to kill zombies.
