AceShowbiz - Before creating The Boys, Eric Kripke was the showrunner for the first five seasons of Supernatural. Fans of both series have noticed a significant crossover in cast members, as Kripke clearly enjoys working with familiar actors across his projects. In total, 13 actors from Supernatural have made appearances in The Boys, enriching the gritty superhero drama with familiar faces from the Winchester saga.

The connection between the two shows isn’t just limited to casting. While The Boys does not heavily lean into its ties with Supernatural, it occasionally includes subtle nods to the Winchester brothers’ story. A notable example is the Season 5 reunion of Supernatural stars Jensen Ackles, Jared Padalecki, and Misha Collins on The Boys screen, which delighted fans of both series.

However, many of the Supernatural alumni have appeared in smaller but memorable roles throughout The Boys, some more recognizable than others. The following list covers all 13 actors from Supernatural who have appeared in The Boys, highlighting their characters and the impact they made.

13) Rob Benedict as Splinter

Rob Benedict is known for playing Chuck, also known as God, in Supernatural. In The Boys Season 4, he portrays Splinter, a supe who can replicate himself. Splinter is a friend to Firecracker and works as a political commentator. Despite his unique powers, his role in The Boys is brief, ending at the hands of Butcher. This cameo offers a humorous twist for fans familiar with Benedict’s Supernatural role.

12) Christian Keyes as Nathan Franklin

Christian Keyes plays Nathan Franklin, A-Train’s brother, in The Boys. His character serves as an important moral figure in A-Train’s storyline. Before this, Keyes had a short role in Supernatural as the archangel Michael, a supernatural antagonist who arrives from an alternate universe to challenge the Winchesters during Season 13.

11) Lesley Nicol as Connie Butcher

Lesley Nicol appears as Connie Butcher, Billy Butcher’s mother, in The Boys Season 2, Episode 7. In Supernatural, she had a one-episode appearance as Katja, a witch who kidnaps and manipulates victims in Season 10. Her character in The Boys attempts to reconcile Billy Butcher with his father, showing a more nurturing side compared to her villainous Supernatural role.

10) Alvina August as Monique Milk

Alvina August plays Monique, the wife of Mother’s Milk in The Boys Season 1. Although Frances Turner later replaces her in the role, August is one of the many Supernatural actors cast in the series. In Supernatural, she appeared in Season 12 as Tasha, a witch, but her role in The Boys gives her more depth as she navigates the consequences of her husband’s dangerous work.

9) Adrian Holmes as Dr. Park

Adrian Holmes has taken on minor roles in both shows. In Supernatural, he appeared as a demon in Season 3 and later as James Turner, Missouri Moseley’s son, in Season 13. In The Boys Season 2, he portrays Dr. Park, a Vought scientist assigned to monitor Becca and Ryan, though his character’s backstory remains largely unexplored.

8) Isaiah Adam as Lance Corporal Dan Miller

Isaiah Adam plays the small role of Lance Corporal Dan Miller in the The Boys Season 2 premiere. His character features briefly in a video with Homelander and Queen Maeve. In Supernatural, he appeared as a forensic technician in Season 7, though his role there was unnamed and minor.

7) Kai Bradbury as Young Kenji Miyashiro

Kai Bradbury has minor parts in both shows. In Supernatural Season 13, he plays an unnamed clerk, while in The Boys, he portrays the young version of Kenji Miyashiro, Kimiko’s brother, appearing in Season 1, Episode 6. The adult Kenji is played by Abraham Lim in the current storyline.

6) Nathan Mitchell as Black Noir 2

Nathan Mitchell takes on the role of Black Noir 2 in The Boys, the replacement for the original Black Noir killed by Homelander at the end of Season 3. This version speaks and has more personality, appearing unmasked more frequently. Mitchell also had a brief two-episode role in Supernatural as Kelvin, an angel who allies with Castiel during Season 12, though his Supernatural role was less prominent compared to his part in The Boys.

5) Jim Beaver as Robert Singer

Jim Beaver’s role in The Boys is a clever nod to his beloved Supernatural character. He plays Robert Singer, a politician nicknamed "Dakota Bob," with a strong anti-supe stance. His character is imprisoned for plotting the assassination of Victoria Neuman in Season 4. In Supernatural, Beaver portrayed Bobby Singer, a father figure and family friend to the Winchesters. Although his The Boys character doesn’t interact with the Winchester actors, there are subtle references to his iconic role.

4) Jensen Ackles as Soldier Boy

Jensen Ackles is a standout in both series, playing very different roles. In Supernatural, he stars as Dean Winchester, a sarcastic and protective older brother who is a natural hunter. In The Boys, Ackles takes on the role of Soldier Boy, a less heroic supe from the original batch of Compound V who is the genetic source of Homelander. Ackles’s portrayal of Soldier Boy brings charisma and dark humor, making him a key figure in the expanding The Boys universe.

3) Jared Padalecki as Ryan Butcher

Jared Padalecki, who plays Sam Winchester alongside Ackles in Supernatural, appears in The Boys as Ryan Butcher, the son of Billy Butcher and Becca. Ryan’s character is central to the series, grappling with his identity and powers. Padalecki’s role marks one of the most significant Supernatural actor appearances in The Boys, contributing emotional depth to the storyline.

2) Misha Collins as Ezekiel

Misha Collins, known for playing Castiel in Supernatural, portrays Ezekiel in The Boys. Ezekiel is a scientist working for Vought who becomes involved in the development of Compound V and the creation of new supes. Collins’s presence adds an intriguing layer to the series, linking the two shows through his involvement with complex, supernatural elements.

1) Jim Beaver’s Character Name Reference

It’s worth highlighting once more that Jim Beaver’s character name in The Boys—Robert Singer—is a playful homage to his Supernatural character Bobby Singer. This subtle detail is a treat for fans who appreciate the connection between Kripke’s two creations and enjoy spotting these Easter eggs throughout the series.

In summary, the crossover of Supernatural actors in The Boys enriches the viewing experience for fans of both shows. From leading roles like Jensen Ackles’s Soldier Boy to brief cameos like Kai Bradbury’s Young Kenji, Eric Kripke’s casting choices reflect his ongoing collaboration with familiar talent. As The Boys continues to develop, it’s likely more Supernatural alumni may appear, further entwining the two distinct yet connected universes.
