Lumine is one of the more powerful villains in Megaman X. Her abilities are definitely very impressive and I don’t think Flashy Flash would be able to last very long against them if he didn’t have so much speed. We can’t ignore the speed though as it shapes the entire fight. Lumine just won’t be able to do anything against that level of ability. Flashy will remain one step ahead of her the entire time and even if she were to fire off her complete arsenal at once none of the hits would even come remotely close to hitting this S rank hero. Flashy Flash is just too far above her level. Flashy Flash wins.
