After seven seasons, Marvel's Agents of S.H.I.E.L.D. has officially come to an end at ABC with the two-part series finale "The End Is at Hand" and "What We're Fighting For." Ahead of the episodes airing, Gabriel Luna -- who played the character of Robbie Reyes/Ghost Rider in Agents of S.H.I.E.L.D.'s fourth season -- marked the occasion by sharing a throwback behind-the-scenes photo of himself watching the show alongside Robbie's creators, Felipe Smith and Tradd Moore.

The photo in question shows Luna, Smith and Moore watching one of Agents of S.H.I.E.L.D. Season 4's Ghost Rider scenes together. Luna shared numerous other photos from his time on the show as well, featuring the actor hanging out with his co-stars, doing some mo-cap work and even holding a toy version of Robbie's iconic black 1969 Dodge Charger. "In honor of the tonight’s series finale of [Marvel's Agents of S.H.I.E.L.D.], here is photo of me, [Felipe Smith] and [Tradd Moore] watching the show together back at my old apartment in Hollywood," Luna wrote on Instagram. "As you may know, Felipe is the creator of Robbie Reyes and Tradd was the OG artist on All-New Ghost Rider, Robbie's debut comic. I've thrown in a few other BTS pics as well. To the cast and crew of S.H.I.E.L.D., working with y'all was some of the most fun I've had in my career. Thank you for [seven] great seasons."

Created by Smith and Moore, Roberto "Robbie" Reyes first appeared in the 2014's All-New Ghost Rider #1, staking his claim as Marvel Comics' new Spirit of Vengeance. Played by Luna, Robbie made his way to live-action in "The Ghost" -- the premiere episode of Agents of S.H.I.E.L.D. Season 4 -- in 2016. Robbie was the focal point of the first half of Season 4, later turning up again for that season's finale. Luna is the second person to play Ghost Rider in live-action, following Nicolas Cage -- who played the original Johnny Blaze incarnation of the character in Columbia Pictures Ghost Rider film duology. Following his run on Agents of S.H.I.E.L.D.'s fourth season, Luna was tapped to reprise his role as Robbie for a solo Ghost Rider series on Hulu, though that project ultimately fell through.

Marvel's Agents of S.H.I.E.L.D. stars Ming-Na Wen, Chloe Bennet, Henry Simmons, Iain De Caestecker, Natalia Cordova-Buckley, Elizabeth Henstridge and Clark Gregg.
