In season 13's "War of the Worlds", an alternate universe Kevin appears as a Prophet loyal to Michael in Apocalypse World. He meets Lucifer and the latter informs him of his counterpart's status, which shocks him. Having a more black-and-white view of the world, Kevin sees Lucifer as evil due to his status as the Devil and apparently can't tell that Michael is just using him and doesn't care either way as Michael promises him a better life once he gets to the Winchesters world. Kevin finds a spell on the Angel Tablet that will open a rift to the Winchesters' universe, but it requires the grace of an archangel so Michael drains some of Lucifer's. Kevin's spell succeeds in opening a rift, but Lucifer uses the opportunity to escape through the rift which closes behind him. Kevin is excited by his success despite the fact that the spell only opens the rift long enough for one person to go through. Kevin is ordered by Michael to fix the problem.
