On Remnant, silver eyes only work on Grimm because they are the only things there that are pure destruction (or whatever criteria they use). However, in a crossover it's possible for there to be other things that meet those criteria. What do you think they are? Bonus points for mentioning fanfics where Ruby uses her silver eyes on them. To start, here's the fanfics that inspired this question:

• In An Honest Soul, Ruby uses her silver eyes on chaos daemons from Warhammer 40k.
• In Windows to the Soul, Ruby uses her silver eyes on the Maverick Virus from Mega Man X.
• There's also a Marvel crossover I forget the name of where she uses them on vampires.
