If a Pokèmon is holding an Eviolite, can it still Mega Evolve?

Question

If you fully evolve a Pokèmon then give it an Eviolite, can it still Mega Evolve? Or will it just stay as the normal form of that Pokèmon?

Ok im stupid thanks
Lol

Answer 1

In order to mega evolve (unless ur names rayquaza), the Pokemon must hold a mega stone. So if ur Pokemon is holding a different item, which in this case is the eviolite, then no, it won't be able to mega evolve. Also, all mega evolutions that exist are fully evolved Pokemon, and eviolite wont give the defense boosts to them.

Confirming that Rayquaza can mega evolve while holding eviolite: https://replay.pokemonshowdown.com/gen7anythinggoes-1076465422

Apparently I'm stupid when it comes to pokemon stuff.

Answer 2

It cannot Mega Evolve, due to it not holding a Mega Stone and instead holding an Eviolite.
