Hi! Do you mind if I use this for a Sith Empire vs Republic Fanon Wiki Project? XD I'm including some outside-Star Wars species because, well... yeah. Anyway, I'll credit you in the image description and trivia section for the character.
nah, the claws would be used as a secondary weapon for things the sabre don't need to be drawn for. it's more convenient to ignite claws with a force operated switch for moments when there is no duel to be had than the sabre.
Can't say I approve predators as sith. I mean Predators are 100% mendolorians, think about it: great warriors, hunters, they honor honor and strength, combat is their way of life, they fight for both cultural and personal developement, they prefer conventional combat to guns & sh..t.
