Suggested by iKnowledge This should be a pretty good fight. Ferus trained at the same time as Anakin Skywalker and was said to be close in ability. Ultimately the gap between them grew though and Vader took him out pretty quick. Meanwhile Lumiya is a character who kept growing stronger and even stalemated Grand Master Luke Skywalker. I remember reading a comic with her and her betrayal was handled really well. As a secret agent she just makes for a fantastic character and it’s nice to hear that she ended up being such a powerful villain. Her whip would be too much for Ferus to deal with on an initial encounter. Lumiya wins.
I think Ferus would still put up a good fight. Considering the woman who trained him’s feats: https://comicvine.gamespot.com/profile/fated_xtasy/blog/siri-tachi-respect-thread/101945/. (You’re welcome to use these for future battles involving her, by the way). And given that Adi Galli was her master, the possibility is there of Ferus giving it his best.
Yeah Ferus is definitely a tough fighter for sure so it wouldn’t be crazy one sided or anything. That said, Lumiya’s just had a lot of great moments on her side as well
