His introduction to Rick Grimes (Andrew Lincoln) and his group was certainly something none of them will ever forget, but if taking out one of their own with a studded baseball bat didn't prove he's someone not be reckoned with, what's to come from Negan (Jeffrey Dean Morgan) on The Walking Dead will.

During a masterclass at the Edinburgh International TV Festival in Scotland, executive producer Gale Ann Hurd revealed that Negan would be a bit of a game changer for the show overall.

"In this new season Negan is the game changer, and whatever we did to someone was going to be unhappy...so we promised we will be picking up where that left off; we are not going to draw it out," she said.

Fans will recall that the season six finale saw a large portion of Rick's group trying to get Maggie (Lauren Cohan) to the Hilltop for medical attention after her pregnancy became complicated. After Negan and his saviors blocked every path they could take, they group became captives. They-Rick, Maggie, Carl (Chandler Riggs), Abraham (Michael Cudlitz), Sasha (Sonequa Martin Green), Eugene (Josh McDermitt and Aaron (Ross Marquand)--were reunited with Rosita (Christian Serratos), Michonne (Danai Gurira), Glenn (Steven Yuen) and Daryl (Norman Reedus) and all placed in a line-up. Negan than chose a victim and started to beat their head in with his bat (Lucille), though the scene was shot through the victim's point of view, and fans won't know their identity until the season 7 premiere.

Several theories have been floated since the April finale about the person who met such an unfortunate end. Many have believed the victim would most likely be Glenn, Daryl or Abraham, though others have suggested it could be Maggie. The only ones who are generally deemed safe are Carl and Rick, since Negan referenced each of them before he took the bat to his victim's head.

The Walking Dead season 7 premieres Sunday, October 9 at 9 p.m. on AMC.
