10 Most Powerful Supernatural Characters
7. Castiel
Our favourite angel in the entire show, and with a soft spot for Dean to boot. Castiel made his first appearance in 2008 and has become a huge fan favourite, helping the Winchesters at every crossroads. Well, except one.
There are few things more frightening on a show like Supernatural than seeing a main protagonist transformed into a villain. We got a taste of it in Season 5 when Lucifer took over Sam’s body, though the far more frightening event was Castiel’s turn to the dark side.
By absorbing all of the forgotten souls in purgatory, Castiel was able to achieve ultimate power and declare himself God, hoping to take over since the existing God, aka Chuck, was still lounging about on Earth somewhere. While his transformation lasted for only a single episode, we know just how powerful he was and could have remained if people did not intervene.
Castiel remains a fan favourite, and while his God-powers would’ve made many events in the show since then go over much more smoothly, I’m sure we’re all glad to have our good old Cass back instead.
