I was always fascinated by this character that appears to serve Horde Prime in the episode "For Want of a Horse" from She-Ra's season one. Not only does this episode give us a better look at the mysterious location surrounding Horde Prime, but we also get to see some wonderful special effects; the mysterious green glow and almost hellish red make for a striking image. The messenger looks very different in design to what we almost expect in the She-Ra series, and although obviously weak and in servitude to Horde Prime, the being looks very creepy, his mask covering his entire face, insect-like in appearance! Oddly this character never reappeared in the series, but was due to appear in the episode that never made it to screen, "The Silaxian Wars."
