Today, The Pokémon Company group revealed that Mega Hawlucha, a new Mega-Evolved Pokémon, is making its debut in Pokémon Legends: Z-A when the game launches on October 16, 2025, for Nintendo Switch 2 and Nintendo Switch.
You can watch the reveal video on the official Pokémon YouTube channel and find additional details on the official Pokémon Legends: Z-A website.

This look’s cool, but i kinda wish they just let players discover it when the game releases and not spoil the surprise.
I think they are trying to get ahead of leakers who I despise the most.
I think this is because of the massive Gamefreak hacked that happened last August of last year. The company behind the franchise wants to make sure nothing else gets leaked so no further surprises be leaked online without their written approval.
