Kevin is the only knighted Minion
In the Minions movie, Queen Elizabeth knights Kevin, conferring him as the only knight-Minion or Minion-knight. He earned this title for all of his work that helped save the Queen’s throne and crown. In the movie, they accidentally uncovered a hidden commercial broadcast for villains advertising Villain-Con.
Scarlet explains her plans to steal the Imperial State Crown from Queen Elizabeth II, promises to reward the Minions if they do it successfully, and threatens to kill them if they do not. In the end, the plan gets reversed, and the Queen gets her throne and crown back and rewards Kevin with a knighthood.
