This trio of figure is from a series of Yuan-Ti snakemen customs I created. Admittedly, it is a stretch to call these "Mythic Legions customs" since they do not use an ML parts (expect for a few daggers), but they were created specifically to go with my ML display (and my other Yuan-Ti custsoms), so here they are.
The base bodies on these are from the Star Wars Black Series Kylo Ren. I wanted my assassins to have a slimmer build than the current Mythic Legions bodies do. Initially, I had planned to wait until 2.0 arrived to make these, but I ended up liking the Kylo body so much, that I went this route instead.
The heads are all from MOTU snakemen, along with the curvy serpent blades. Two of my assassins carry poison-tipped blades while the third one wields a crossbow with quiver that I got from a Spawn Viking Age Troll figure.
The final pic shows the entire series of Yuan-ti customs..
