Merfish loves Pokemon and he loves GTA V, in fact he says so in the description of his amazing video:
Today I turn 23 years old, and for 17 of those years I have devoted my life to Pokémon. It's one of the few video game series that matches GTA in my heart, so surely a combination of the two would be something special, at least for me. So this is my birthday gift to myself that I wish to share with all of you.
So watch the video below and give some love to the guy, it's a brilliant vid!
