The live-action version of Reggie is portrayed by Ross Butler and Charles Melton in Riverdale and Vedang Raina in The Archies.

(Reggie seems to show journalistic aspirations himself, often working as the editor of the high school paper, Blue and Gold.

Another cousin, Regina, displays Reggie's cruel humor and bullying tendencies, but after a date with Jughead she appears to have enjoyed herself.

Reggie Mantle's chief characteristics are his love of sarcasm and practical jokes, his vanity, his athletic abilities, and his interest in dating multiple women.

[9] These looks have lasted months (rather than been contained within a single story) and have included several incarnations of sideburns, pomaded, short, shaggy, and even a ponytail in the early 1990s.

Reggie is one of the founding members of the band The Archies, serving primarily as their bassist and occasionally as lead guitarist.

He views himself as the most important and talented member of the group—and has gone to great lengths to prove it, such as hiring groupies to scream his name during concerts.

He has expressed horror at the idea of being tied down to one solitary female, saying that, "having one girl is like having one peanut, one potato chip."

Other than Veronica, Reggie is romantically interested in Midge Klump, the girlfriend of brawny but dimwitted athlete Moose Mason.

A running gag in the series features Reggie attempting to spend time with Midge without attracting Moose's anger and jealousy.

Another arc features Reggie falling in love with Veronica's cousin Harper and developing a long-distance relationship with her.

On certain occasions, Reggie shows a kinder side where he will come to the aid of his friends or total strangers, although he prefers to keep these good deeds secret.

He immediately regrets his actions and tries to carry Hot Dog to a vet, failing that, he takes him to Jughead's lawn so that he can die at home.

Reggie survives with the others on the road, growing increasingly bitter towards Archie for becoming a natural leader and thriving while he is continually wracked with guilt for starting all this horror.

Reggie eventually goes out hunting with Kevin and tells him how he caused the apocalypse, how he killed Hot Dog, how he fears he might be a sociopath and how he thinks the only way to end the zombie plague is by offering himself up to the horde so they can have their revenge and hopefully stop their rampage.

The zombified Hot Dog walks forward, and Reggie kneels before it, expecting it to kill him and accepting his fate.
