Since I am hyperfocused on the comic I don't have the energy to work on full illustrations and I feel anxious about it but I can still deliver doodles. Here's a Legion headcanon: As slaves wear rags with an X, Soldiers, specially the ones with tribal background, are physically branded with the same mark on their skin. This could happen in a sort of a very important rite of passage into the military or something more akin to a purely sadistic humiliation ritual. Either way it stays as a scar that reminds them who they belong to and that they are still subjugated slaves even if they manage to get promoted into very high ranks.
That's my excuse to draw topless Vulpes.
