Ever wondered what a Metapod would look like if it was combined with a Bulbasaur? How about an Ekans with a Pikachu? Now you can find out with Alex Onsager's hilarious Pokémon Fusion site, featuring numerous Pokémon from the old-school original 151.
What's particularly great is that by swapping which species of Pokémon comes first will change its dominant physical  characteristics—also you can randomize. (There's also social media integration so you can share favorites with friends.)
This one can safely be filed under the ever-expanding list of internet time-wasters, but it's definitely good for a laugh (try mixing a Psyduck and Haunter if you don't believe us). Here's hoping for more in the future.
