Can you use a thunderstone on luxio?

You can't use a Thunder Stone on Luxio to evolve it.

Here's why:

* Luxio evolves into Luxray by leveling up at night. It doesn't evolve through any specific item.

* Thunder Stones are used to evolve certain Pokemon into their Electric-type forms. However, Luxio is already an Electric-type Pokemon.

Let me know if you have any other Pokemon evolution questions!
