The royal guards-including Luna's bat-winged guards-were featured in a cut scene from Slice of Life in which, in the absence of other ponies, they would have joked around doing impressions of Celestia and Luna.
Michael Vogel suggested an episode about the royal guards, but it was never produced. Procession of trumpeters in The Cutie Mark Chronicles. The unicorn guards first appear in the show's title sequence, standing at the feet of Princess Celestia's throne. Their next appearance is in The Cutie Mark Chronicles. Set in Twilight Sparkle's flashback, eight gray unicorn guards play fanfare for Princess Celestia as she comes on stage and raises the sun for the Summer Sun Celebration. The guards remain expressionless throughout the ceremony.
