Re costume the headdress and face markings are a must for me. She could have the hood when she first shows up though to keep a bit of mystery.
If she actually shows up S2, ....
Costume choice?:
The Same? An update?
She's older, pretty sure the belly shirt is out , the more hooded version?
Serape?
Something entirely new?
And what role do you want her to play?
Is she after the Dark sabre?
After the Yoby?
Is she Competition? An ally?
Seen as foe or friend? Both?
You want just a cameo?
Done in one episode?
A fleshed out ongoing recurring character?
Could this be a back-door pilot for her own show?
