|“||I don't know, but guys like us, like you, in a town like Riverdale, we don't have a lot of options. So, even if something bad could happen, we go for it, 'Cause what if, for ten minutes or maybe even just for two minutes, we're not alone.||”|
|— Moose to Kevin[src]|
He, along with Midge, were attacked by the Black Hood though only Moose was harmed as he shielded Midge from the gun fire. With the help of Kevin, he was rushed to a hospital where he later made a full recovery.
It is currently unknown whether or not Moose grew up in Riverdale. There's also nothing known of his home life, such as his family. However, his closest friend appears to be Reggie Mantle, as they are almost always together.
With news circulating throughout town of Archie's father being shot at Pop's Chock'lit Shoppe, Moose, his girlfriend Midge, and the Bulldogs joined Archie down at Riverdale General Hospital in a show of support for him and his family during their time of need.
Deadly Days at Lovers' Lane
After learning that Riverdale High's former music teacher, Ms. Grundy, was murdered in her Greendale home the previous night, Moose and Midge attended Retro Night at Pop's Chock'lit Shoppe, where they scored some Jingle Jangle from Reggie in the diner's parking lot. Unbeknownst to them, they were being photographed by Alice Cooper. Later that night, Moose and Midge drove out into the woods, where after taking the Jingle Jangle, they began kissing in the car. However, before they could go any further, a man wearing a black hood appeared from the darkness, shining a flashlight into the car, and firing several shots.
Moose was joined at Riverdale General Hospital by Archie and Reggie after being shot multiple times by the Black Hood. Fortunately, he would survive the attack and Midge was left unharmed due to his heroic actions in which he used his own body to shield her from the gunfire. Archie assured him that he saved her life. After stealing his dessert, Reggie asked Moose if his nurse was attractive. If so, he ran the risk of getting a boner during a sponge bath. Moose laughed in response. Archie then questioned him about the shooter's appearance, mostly regarding the black hood he wore to conceal his identity and the color of his eyes, the answer to which Moose did not provide, as he was cut off by Midge, who entered the room, and described the shooter's eyes as being blank, comparable to the eyes of the devil or Michael Myers.
A couple days later, Moose received a visit from Kevin Keller, who he informed that Midge wanted to thank for saving their lives. He wondered what Kevin was doing in the woods, to begin with, though Kevin turned the question back onto Moose, asking him what he was doing in the woods with Midge, beyond taking Jingle Jangle, which everyone had already been made aware of. Moose claimed that it was Midge's idea. She had a wilder side that she occasionally indulged in. While he had genuine feelings for Midge, he wasn't entirely sure that they were a match. Noticing a trouble looked on Kevin's face, Moose asked him if everything was alright. Kevin replied that he had been making bad decisions lately and lying to his father. He knew it was dangerous, but he couldn't stop himself from sneaking around the woods at night, looking for hook ups. Its as if he didn't even care about his own well being. Moose explained that this was due to the lack of options for guys like them in Riverdale. So, even if something bad could happen, they go for it because what if, for however long, they're no longer alone. As Kevin headed out the door, Moose told him that he could stay or come back at a later time if he wanted to hang out or talk.
In the days leading up to Christmas, Moose and Midge entered the student lounge at school to find Archie, Betty, Cheryl, Kevin, Veronica, Jughead and Josie opening presents as part of a Secret Santa gift exchanged. Moose and Midge were welcomed back by hugs from Josie, Reggie, and Kevin.
Moose was approached by Kevin while at his locker to see if he wanted to accompany him to the Bijou to watch the 2018 American romantic comedy-drama film Love, Simon. Unfortunately for Kevin, Moose had already planned to go with Midge though he did invite Kevin to tag along, claiming that Midge knew all about them. Supposedly, she was cool with it, but Kevin passed on the offer nonetheless.
The following night, Moose and Midge stopped by Pop's Chock'lit Shoppe. There, they found Kevin eating alone. So Midge invited him to join her and Moose in their booth. Midge assumed that Kevin would be meeting someone at the Bijou, but unfortunately, he wasn't. Which Midge found to be unacceptable. She offered to help him find a date, suggesting one of the new Southside Serpents that had recently transferred to Riverdale High following the closing of Southside High. She had heard that at least one of them was gay, Fangs Fogarty. However, Kevin explained that he didn't think he could date someone named "Fangs". Moose interjected that Kevin should at least give Fangs a chance since he was attractive though Midge disregarded his comment. She then asked how Kevin and Moose became friends. Though Moose and Kevin came to know one another through pre-planned sexual encounters, Kevin told her that they were lab partners in Biology.
Moose is an attractive young man with tan skin, hazel eyes, and dark brown hair. He is tall, with an athletic build, due to his place on the football team. He doesn't put much thought into his choice of clothing, typically a jacket or hoodie with jeans.
Like Reggie, Moose embodies several characteristics usually associated with the stereotypical jock. He doesn't appear to be very smart nor does he seem interested in school. Football, and concealing his true sexual orientation are his biggest concerns. However, he has been known to have a more compassionate side; volunteering to help work at Andrews Construction following the exits of Fred Andrews's crew.
Moose is also very heroic, as he risked his own life to save Midge Klump, his girlfriend, from the Black Hood. Due to his sexuality, like Kevin's, he is also very understanding when it comes to relationships with other dudes, and can be very comforting to the other person when they seem to be lost.
- Neither Moose nor Reggie Mantle were cut from the football team the way that Chuck Clayton and a number of other players were, when the scandal of Chuck's "playbook" broke, despite their names being clearly visible in the book.
- Moose drives a 1965 Chevrolet Chevelle Malibu Z16, which license plate is: 3CL 678 as seen in "Chapter Fifteen: Nighthawks". However, he drove a 1972 Dodge Dart Swinger in "Chapter One: The River's Edge".
- Moose had blond hair and brown eyes in the comics.
- Just like the TV series, Moose is in a relationship with Midge Klump in most if not all comics iterations. In 2015 "Reggie and Me" it is revealed that Moose is the eldest of five children.
