Anyone heard of Pokemon 731?

It scares me just typing the name...

I SWEAR THIS IS NOT A CREEPYPASTA, and this may be a bit disturbing to some people.

Apparently, in the original Japanese version of Pokemon Red and Blue, a strange pokemon appeared in Route 7 on the 31st tile of grass. Known only by it's arranged number, 731, this thing was basically a bunch of pixelized pictures that kept flashing over and over. Those pictures, though, had a meaning. One of the pictures had a resemblance to Shiro Ishii, the commander of Unit 731. Another picture looked like a picture of surgeons operating on a person (for lethal human experimentation...) which was a kind of procedure Unit 731 carried out. And the last picture was a picture of the place where Unit 731 disposed of the "bodies"... if you know what I'm saying. Unit 731, in a nutshell, was a place where they conducted experiments on... well, by this time you'd already know.

This is not a creepypasta. Look up Unit 731 on Wikipedia and then Pokemon 731 on YouTube. You will see it is not made up.
