23 Things You Probably Didn’t Know About Pikachu

Some fun facts to celebrate everyone’s favorite electric mouse.

Summary (TL;DR): Pikachu remains one of Pokémon’s most beloved characters in the franchise. Over the years, the electric mouse has appeared on airplanes, parades and even protests for climate change. Here’s a list of 23 things you might not know about Pikachu.


Out of all the Pokémon out there, Pikachu holds a special place in my heart. In the anime, he wasn’t just Ash’s Pokémon — he was a friend, a partner, and in some cases, an equal. He was kind and always had Ash’s back, but he also had a rebellious side and wasn’t afraid to show it.

I’m not the only one who’s a fan of the yellow electric mouse. Since his debut in 1996, Pikachu has arguably become the most popular and recognizable Pokémon. Not only is he adorable with his brightly colored fur and cheerful expressions, but he’s also an absolute badass.

In honor of Pikachu’s enduring popularity, here are 23 interesting facts you might not know about this iconic Pokémon:
