Which of these characters was created first?

Mickey Mouse is my boss.

Yess I read the story about Walt Disney 👍🏼👍🏼Mikey mouse is my favourite cartoon 😍 when I was child I watched many times on TV.

I love Mikey mouse ❤️

I thought scrooge is old so absolutely it will be an older character my bad

Fun fact: Walt Disney was afraid if mice but created Mickey Mouse

I got a Mickey Mouse plush from Disney Land when I was 15.
