Princess Celestia as General Hawk. Specifically his original v1 incarnation when he was still a colonel, operator of the G.I. Joe Mobile Missile System (MMS), and one of the original green 13 (OG 13) G.I. Joe characters/action figures from the 1982 line relaunch.

I wanted to do a version of Hawk in his original appearance, and since I had Celestia in the role for this series, I figured on using the younger pink-maned version of Celestia to go with the younger Hawk. Additionally, both the original v1 Hawk and the more well known v2 version of the figure also have completely different hair colors, so having pink-maned Celestia for this version fits.
