Baby Yoda is from The Mandalorian an space western web television series that premiered on Disney+ (streaming Service) on November 12, 2019. There are lots of awesome characters in the Madalorian but the one that stole the show would have to be Baby Yoda.
Baby Yoda could be the love child of Yoda and Yaddle from the Phantom menace. The other option is that baby Yoda is a clone of the original Yoda. We don't know as of yet.
All we know is baby Yoda is cute and deserves an image for making memes on this site.
