Let’s talk about Elgyem here for a little bit. It’s pretty much generally accepted that it’s an extraterrestrial Pokemon, and its appearance on Earth is shrouded in mystery, possibly because it’s able to change memories. It challenges foes by squeezing their brains. The dex entires say that it causes massive headaches, but I’m pretty sure that’s not all you suffer if your brain is being squished.
And somehow, it’s still a helpful and intelligent alien that flies around and tries to protect people. And it flashes its little hand lights! Imagine a bunch of Elgyem and Beheeyem suddenly communicating with their hand lights over your neighborhood in the middle of the night. I bet it looks amazing!
