I thought it was less? O.o Oh well, just ignore that. Relied on my friend's word rather than on Serebii or Pokemon Database xD

Luxray has a base speed of 70, while Umbreon has 65.
So, Levi would only be a tiny bit faster than Zuria, if at all. In a realistic setting I think the difference would be negligible.

Zuria still has HP and Defense though. Like, seriously. Luxray has 79 Defense and 79 Special defense while Umbreon has 110 def. and 130 special def. Luxray may have a higher attack, but It's still gonna take a few hits for Levi to do any real damage, especially if she hits you with just spark or something, since Luxrays special attack is only 95.

Luxray's attack is 120, though. So....yeah, get hit by Wild Charge, and yeah, you're gonna hurt a bit xP

If anything, I'd say Levi is a glass cannon that can do massive damage, but can't take much damage herself. Zuria is a wall that's able to heal herself with moonlight xP
