Is that Mario backstory still canon? I mean Metro Kingdom is the closest Super Mairo games ever got to Earth... outside of Mario Is Missing!
I mean I know the DiC-era of Mario cartoons established some lore, they also said the Koopalings were the legitimate children of "King Koopa".
I mean, maybe they are, and after King Koopa's death in the first game is brother Bowser usurped the throne or something.
Didn't Mario were raised by some Yoshi(s) since a baby?
But doesn't that mean Luigi isn't growing up together with Mario?
The story is always changing so I don't remember what's canon anymore.
Some fans just treated it as different universe of Mario like a multiverse.
Once thing that I know Mario's movie is a separated universe,
his movie was even being continued in comic form.
