@Tanno I'm glad I'm not the only one who knew that lol. Yup. Raiden's original name is inspired from
Raijin as the original spelling, but MK used Raiden. It's funny because people always think "oh Raiden came from BTLC" but actually more so from Japanese mythos, the only thing from BTLC that's the same is the hat other than that, Raiden pretty much is Japanese lore inspired.
And as someone else mention, Fujin is also known as the Wind God in Japanese mythology as well.
