Look at those eyes...staring into your soul..
I've been a fã of Rosalina since I was in kindergarten, and I know a lot about her. So when Mario Kart 8 came out, a new unlockable character was in the roster. This was Baby Rosalina of course, and I bet most fãs would be excited that Rosalina finally has a baby version of herself. I, on the other hand, think that there is no way she could be related to, or be the past Rosalina.
She can't be the past form of Rosalina, and here's my evidence. If you're a true fã of Rosalina, you would've played the game Super Mario Galaxy. Once you unlock the kitchen, you also unlock another room, The Library. In there, every time you defeat Bowser, Rosalina will read you a new chapter. This story she reads is none other then her backstory of how she got to be the Mother of the Stars. When she was about 8 years old, a Luma crashed into her yard, stating it was looking for its Mama. Rosalina looked into a telescope for months trying to find it's mother, with no hope. She then decided to fix Luma's o espaço ship and fly around. In the storybook, Rosalina's hair was laranja and she didn't have a bang over her eye. She was also definetly NOT a baby when she got into space, so this proves Baby Rosalina is NOT Rosalina's past self.
Baby Rosalina also can't be Rosalina's offspring either, and Mario and Luigi Partners in Time proves it. As many of you know, Baby Bowser was indeed Bowser in the past, and Bowser Jr is Bowser's offspring. This means that the word "Baby" in front of a character's name shows that the character is for example, Mario from the past. The word "Junior" after a characters name means they're a character's offspring.
As I just proved in the segundo paragraph, Baby Rosalina is not Rosalina's past self, and her name isn't Rosalina Jr, and if it was, that would mean she's Rosalina's offspring. So who or WHAT is Baby Rosalina? A wannabe Rosalina? No. I, for some odd reason, think she's an evil robot created por Bowser to spy on Mario! Weird, right? Let me know what you think!
