After being on air for 15 years, Supernatural ended in November 2020, but with the prequel announced last year, it is safe to say that the Supernatural universe is here to stay. The prequel will revolve around John and Mary Winchester and is set to be narrated by Dean, but whether there will be any appearances from Dean or other major characters is still unknown. The possibility that the viewers might get to see some familiar faces is extremely high, especially angels and demons because many of them existed before the birth of Sam and Dean and thus, can make an appearance in the prequel.
Apart from major characters, there are many minor characters in the show that the fans have loved and can show up in the prequel. It will definitely be fun to witness the backstory of those characters that have burrowed their way into people’s hearts in a short span of time. There are even some characters who had an appearance in just one episode but managed to leave an impression on the fandom.
10 Jesse The ‘Antichrist’ Kid
Jesse Turner is one of the most interesting minor characters to have ever appeared on the show. He is a young kid who appeared in episode 6 of Season 5, ‘I Believe the Children Are Our Future’.
It’s a shame that fans don’t know anything about his whereabouts after that episode. Even though he never appeared again, fans loved to speculate about his return, as he certainly had powerful abilities. He could have been a huge help to the Winchester brothers throughout the show but the ‘Antichrist’ storyline was unfortunately dropped.
Supernatural introduced many angels throughout the 15 seasons and one of them was Ishim, who appeared in Season 12 Episode 10. He was the commander of a flight of angels in which Castiel once served.
Ishim’s appearance helped shine a light on how much Castiel has changed since he met Sam and Dean. He reminded the fans how Castiel turned from a heartless soldier to a caring friend. He didn’t appear again because he was killed in the episode, but the fans would have loved to explore his past relationship with Cas.
8 Cassie Robinson
The first serious relationship Dean Winchester ever had was with Cassie Robinson. Cassie came in Season 1 Episode 13, ‘Route 666’. She is a reporter and the daughter of Martin Robinson, who died in the episode.
Cassie was a great character, as she was adamant in figuring out the cause of her dad’s death, even when the authorities brushed it off as a mere accident. She never appeared again and was never mentioned again, even though she is still alive. She could have shown up later in the show and it would be great to see her reaction to how much Dean has grown and changed.
Season 5 had many memorable monster-of-the-week episodes and one of them was episode 7, ‘The Curious Case of Dean Winchester’. The antagonist of this episode was a 900-year-old witch, Patrick.
Patrick’s charm and his mastery of poker were compelling and kept the viewers on the edge of their seats. His storyline wasn’t neatly wrapped up as he maintained his hunger for immortality at the end of the episode. So, he may be still stealing 25 to 50 years off of people’s lives. The Winchesters should have done something about him as he is pushing people to their graves much sooner.
Madison came in episode 17 of Season 2, ‘Heart’. She was a werewolf with whom Sam fell in love.
What made her memorable was how she was ready to die after knowing about the damage she was causing and how quickly she became so important to Sam. Even though Sam had to kill her, it was probably the hardest thing he ever had to do, as he was in tears during the act. She is later mentioned multiple times in Season 4 and Season 6, demonstrating her impact on Sam’s life and on the show.
5 Lee Webb
Lee Webb was a close friend of Dean when they were kids and he used to hunt with Dean and his father, John. He appeared in episode 7 of Season 15, in which Dean and Lee are reunited.
It was heartening to see Dean so carefree with Lee and the fans got to have more insight into Dean’s childhood. Lee turned out to be a monster in the end and Dean had to kill him but he revealed a side of Dean that is rarely ever shown in the latter seasons of the show. Also, it’s surprising that Dean doesn’t mention him to his brother when he returns after killing him, urging fans to ponder how much else he has kept from Sam about his life.
Sully is one of the most important aspects of Sam’s childhood. However, the viewers don’t get to see Sully until Season 11 in episode 8, ‘Just My Imagination’.
The episode sheds a light on Sam’s childhood and psyche brilliantly and at the center of it is Sully. Through Sully, Sam’s lonely and rough childhood is put into perspective and it shows how much he craved a friend when his family abandoned him. He is mentioned again in Season 15 in a flashback scene of Sam and Dean’s childhood.
3 April Kelly
April Kelly was the name of the vessel of an unnamed reaper, who had a single appearance in Season 9’s episode, ‘I’m No Angel’.
April was a key character during the human phase of Castiel as he tells the Winchester brothers later that his time with her was very educational. This leads to him revealing that he had sex with April before she tortured and killed him, which was his first time having sex with anyone. All in all, Cas gained a new perspective on humanity and a deeper understanding of human desires because of April. She was mentioned again in episode 9 of the same season.
A Supernatural fan can never forget the 200th episode of the show, ‘Fan Fiction’, which featured the Supernatural musical play. The director of the play was Marie, a student at a girls’ school.
Marie was a headstrong girl who did not like the ending of the Supernatural books written by Carver Edlund so, she wrote her own ending to the story through her play. She was supposed to be a representation of the actual fandom of the show and it was a great salute to the fans. Since she was so relatable to so many people in the fandom, her showing up again would have been a pleasant treat.
1 Mrs. Butters
Mrs. Butters was a wood nymph who appeared in episode 14 of Season 15, ‘Last Holiday’.
The fans get to see some of the most heartwarming scenes in this episode where the brothers are having moments of peace, happiness, and celebration after hunting monsters and Mrs. Butters plays a huge role in this. Her character forced viewers to see Sam and Dean as humans and not just heroes. It leads one to wonder what else she could do with her powers and she may have helped Sam and Dean fight Billie and Chuck in the latter episodes of the season.
