Oh. My. God.
This is the coolest thing I’ve ever seen, and I mean that without any sort of hyperbole. Some benevolent genius has decided to bless us with the invention that is the Pokemon Fusion Machine, where you select any two Pokemon (up to #78 Rapidash at the moment, but more will surely be added) and you combine them with another Pokemon, creating the kinds of hilarious and awesome hybrids you see above.
Up there we have Ratdrill, Maduck, Butterape (hah!), Alacruel, Golbell and Squirtwag. But the possibilities are endless! Well not endless, but pretty damn extensive, and anyone who is good at math can come up with an exact number of combination to be made. But remember, a Ratatta plus a Beedrill is not the same thing as Beedrill plus a Rattata. One field takes the body, the other the face and color, creating two different creatures for each pair, doubling the number of possible combinations.
If you don’t spend at least the next five minutes playing with this, I’m surprised you’re reading this site at all.
