Pokémon fans, listen up, Professor Oak's had a makeover.
The new prof looks totally different to the Samuel Oak we know and love.
He's swapped his white laboratory coat and short hair for sunglasses and long hair and a beard.
And Oak's not just got a laid-back look, he's got a new name too - Grand Oak.
It's part of a new app, Pokémon Home, being launched by Nintendo.
It's a cloud service that lets users move Pokémon they've caught and trade them on the go, launched on several platforms including Nintendo Switch and Android and iOS devices.
The new-look character Grand Oak will take users through the process of joining up.
