The United Algolian Alliance's flagship, the Rimfire, carried a complement of ten Sentinels. These, and their pilots, were called "Fireflight squadron." Originally I envisioned all ten Sentinels sporting the same red-and-white color scheme, but once I'd recolored their final boss -- the Gigakaiser -- in crimson, I changed my mind. Instead it occurred to me that the Sentinels could be color-coded, much like your Super Sentai/Power Rangers schema. Might make it easier to keep track of changing battle conditions.
Anyway, I grabbed some random free-for-public-use tribal vectors to decorate the individual shields. Can't remember where I found them, honestly. But this was a quick(ish), just-for-fun project, so I didn't wanna sweat these details. Oh, and I added an eleventh Sentinel -- the unknown unit zero. Because, y'know, anime!
As usual, I don't own the lineart for this drawing, I did it for R. Talsorian Games, who owns the art and ideas herein. No infringement intended nor implied, this is just some fan work.
