On this day in 2008, a certain blue-eyed Angel strolled on into a barn and directly into all our hearts. 😍

17 years of Castiel. 💙 Eternally grateful to @mishacollins.bsky.social for bringing one of my most favorite characters to life!

Happy 17th "Birthday," Cas! 🎉💙 #HappyBirthdayCastiel #SPNFamily

I am bad at math but I'm pretty sure this is at ✨almost✨ a quarter of a million dollars. If you have $18 to spare it would be neat if we could reach that milestone in honor of Castiel's introduction to the Supernatural universe give.randomacts.org/campaign/724...

Misha Collins dressed as Castiel holding a young child (my son Max) who is dressed as a bee. They both look adorable. This was a photo op taken by Chris Schmelke at a Creation Entertainment Supernatural convention.

Another Cas Day favorite: Thank you for watching the bees 💜

The date popped up suddenly in my feed....

People who celebrate a fictional character's birthday are weird. Yes, that's me, so #HappyBirthdayCastiel

Thankfully, he will have his vessel to lead him to getting registered and to the voting booth. Odds are that he will join the campaign to get everyone, especially the youth to vote. (Especially if you are in one of the swing states #happybirthdaycastiel #SPNFamily #SPN #mishacollins #seventeen

Please bring him baaaack! We need him, we really do

Happy birthday to the “stiel” part of my mental illness. 17 years ago you burst through some barn doors showering sparks from overhead and changed so many lives.

Also can we take a moment to appreciate the look on that BAMF’s face?? I got that op back and about died.

#HappyBirthdayCastiel

Thank you for making him the iconic Angel, that he is. #HappyBirthdayCastiel

#HappyBirthdayCastiel, I wish you all the hamburgers of Heaven 🥰

17 years ago today an Angel of the Lord had his dramatic entrance in Supernatural. The rest is history, as they say. But without him the show would‘ve been half as good and lastet half es long.

Cas, you‘ll always be my fave. Happy Birthday, Angel!

P.S.: Also, Cas is gay 🌈

It’s that time of year when I share this photo (and my birthday) with my favorite baby eldritch creature. Happy birthday, Cas - I hope you soar higher than your Chrysler building true form this coming year. 🎈

Castiel came onto the show and into our lives 17 years ago and irrevocably changed everything! Here's to the angel with too much heart! To the one who refused to follow the script. Who rebelled, fell in love, and gained a found family along the way. #HappyBirthdayCastiel

Happy birthday, Cas. We might not always see eye to eye (because I’m 5’ tall) but I still love you. #happybirthdayCastiel

Every legacy show needs a character with an immediately recognizable and iconic silhouette. And Castiel came in 17 years ago and said "I'll show you recognizable and iconic." Happy Birthday to the character of all time. #HappyBirthdayCastiel

Happy birthday to the fictional character that became for me a life changer #happybirthdayCastiel

Thank you @mishacollins.bsky.social for creating such an amazing character. 💙
You taught the world that kindness flies on quiet wings beneath wide skies, spreading hope where pain has been... 🩶

"So spare me your contempt Castiel, the self-hating Angel of Thursday. You know what every other version of you did after 'gripping him tight and raising him from Perdition?' They did what they were told. But not you. Not the one off the line with a crack in his chassis." 
#HappyBirthdayCastiel 💙

Happy Birthday to my best friend, Cas. You changed ME and I love a lot of people because of you. <3

#HappyBirthdayCastiel

17 years of Castiel and 17 years as an spn fan for me. I'm glad all of this and all of you are still in my life #HappyBirthdayCastiel
