Reggie comes from a medium-rich family. He isn't as wealthy as resident heiress Veronica Lodge, but he always has the latest electronics. Reggie's father works for a newspaper printing company, where he is the boss. Reggie sometimes uses his dad's job to influence others to get what he wants. Reggie's dad looks a lot like him, except his hair is graying and he is balding. Reggie's mother is very rarely shown in any of the Archie comics. In of her appearances, she is depicted as a slightly overweight, dark-haired woman who is very nice, contrasting with her son's personality. Reggie is an only child, but he has several cousins, including a very petite little girl named Marcy, and a wise-cracker named Regina.
Reggie is a typical bully-type. He loves playing pranks on everyone around him. Most of his antics are typically harmless, but immature. Reggie has a number of gadgets and toys that he usually brings around, like a fake ice cube with a bug in it, a rubber hand, and some pepper-flavoured candy. In one issue it was revealed that Reggie was Riverdale Prank Store's biggest customer, and that he personally knew the owner. Reggie keeps a calendar marked with dates that he pulled particularly amazing jokes on people. However, not all of his pranks go the way they're planned to. In many stories, they backfire, and Reggie's the one who ends up getting tricked!
He enjoys making fun of his nemesis, kind Archie Andrews. Tripping up Archie was once declared his favorite hobby. In truth, he's jealous of Archie because he's dating Veronica, who Reggie has a slight crush on. In some issues, Archie even seems to be better at sports than he is, adding to the jealousy. Reggie denies this whenever Archie points it out, though. Reggie's other victims include Dilton Doiley who is Riverdale's resident boy genius, Jughead Jones who is Archie's best buddy, and sometimes even Moose Mason, a big bodybuilder who isn't very smart. Sometimes Reggie even goes as far as to try to pull one over the teachers at Riverdale High, Ms. Grundy, Mr. Flutesnoot, and Mr. Weatherbee. In one story, Reggie placed a fake recording in Mr. Weatherbee's office that makes meowing noises. Thinking it was a cat, Mr. Weatherbee looked for it all afternoon.
Reggie is also somewhat of a player. He has dated girls that range from baseball players to local models. However, none of these girls last very long with him. His status is still single, and he likes it that way, although sometimes he'll long for a girl just because she has "forbidden fruit" appeal.
Reggie has a super ego that could sometimes be described as the size of a continent. He thinks he is God's gift to women, and he doesn't hide it. His bragging can be a turn-off for many people, though. He doesn't seem to realize it. Sometimes he'll go off talking about himself, and it'll be hours before he even realizes that they've stopped listening to him! Most of what he brags about are great accomplishments he's made in sports teams. Reggie's ego also forces him to carry around a comb and a pocket mirror at all times, in case the wind messes his hair up. Also, he is often shown combing his hair and staring at himself in the mirror. He once held a record in Jughead's "`Riverdale Records" book for the most hours spend staring at himself in the mirror (8). He is the only Archie character to have gone through many different hairstyles, keeping up with what was popular at the time that the comic was written. Reggie's nickname for himself is "Mantle the Magnificent", while others call him "Mr. Ego".
Reg is on many sports teams featured in his high school of Riverdale. He has been in track, volleyball, tennis, basketball, football, soccer, and basketball, among many. Once he lost a dare and had been forced to join the cheerleading team. He has been shown to be proficient in sports and has set many school sports records. In some issues, he is portrayed as being the best player in the team. Reggie takes much pride in the fact that he's one of Riverdale's best athletes, and he doesn't let people forget it.
Despite everything, Reg has a softer, kinda side. This was demonstrated when he was caught by Betty reading to an old woman named Mrs. Finklehoff in a senior's residence. Reggie made Betty swear never to tell anyone, and said that he preferred it if he could keep the "bad guy" attitude he worked so hard to get. Also, in one issue, when a boy was crying during Christmas, he proceeded to buy him a teddy bear despite being shown to be disgruntled.
Even though Reggie constantly fools Archie over and over again, in many issues the two are considered very good friends. Archie often helps Reggie out when he's in a tight spot, and vice versa. The two sometimes double-date with Betty Cooper and Veronica Lodge. Jughead Jones is one guy Reggie seems to be rarely on good terms with. Reggie is constantly trying to trick and manipulate Jughead. However, Jughead almost always wins his battles with Reg, proving that he's smarter than his shabby appearance deems him.
Reggie may be a player, but Veronica Lodge and Midge Klump are two girls that he falls for over and over again. Veronica, or simply "Ron" or "Ronnie", is a spoiled rich girl who lives in a huge mansion. Her father is Hiram Lodge, who Reggie can easily charm into letting him date Veronica. Ron, however, doesn't really like Reggie, preferring Archie over him because Betty also likes Archie and also because Reggie has an even bigger ego than she does. But on occasion she does date Reggie, if only to try and make Archie jealous, or if she's sick of Archie constantly unable to pay for their dates, and wants a change of guy.
Midge Klump, Reg's other crush, is a nice girl with short black hair. She's dating Moose Mason, Riverdale's strongest guy, which makes her all the more appealing to Reggie because he can't get her that easily. Moose is very jealous of anyone who flirts or even talks to Midge, and beats up any guy who tries. Reggie is very careful to avoid Moose on the rare occasions that Midge and him go out, but somehow Moose always finds out and beats him up. However, this does not stop Reggie, and he is still planning ways to get Midge all for his own.
Betty Cooper, a sweet blonde girl, is someone who Reggie is in extreme contrast with. But in one issue, Reggie saves her from being hit by a speeding truck, and Betty develops a crush on him. She knits him a sweater to show her love. Reggie later returns the crush, and the two of them go out for a while, much to the displeasure of both Veronica and Archie. This romance seems to be true love. But it doesn't last, once Reggie realizes that he's not staying true to his bullying self and Betty also realizes that Archie is the one for her, and that she's dragging Reggie down. The two broke it off, but still remain close friends, if in secret.
Big Ethel is Riverdale's ugliest girl. She has a major crush on Jughead, and if she sees him, she'll start chasing him. Jughead doesn't like her at all. Reggie once tried an experiment to see how someone's behavior changes. He showered Big Ethel with attention. Ethel, in return, falls for Reggie. To Reg's shock, he realizes that he likes her too. The story ends with Reggie telling Jughead that he's a lucky guy for someone like Ethel to like him. However, the Ethel/Reggie romance was never in any story again.
Reggie is the bassist and background vocalist of the Archies. However, it is not made clear whether Reggie plays the guitar or the bass. A few times fans called him one of the greatest guitarists of all time. This is curious because normally a typical band would have a guitarist and a bassist, not both of either instruments.
