Hello everyone, and welcome to" My Baby Brother Luigi". It about Mario raised his baby brother Luigi, who was turn into a baby by Kamek. Now, Mario have to raise him. Anyway, I do not own these characters and they are belong to their owners. I hope you guys enjoy it and see you all in the next chapter, bye!!!

Luigi stood by helplessly watching Mario and Bowser fight it out while Princess Peach is lock in the cage. Mario wouldn't dare let any of his princess come to harm because of him, especially by the hands of a monster like Bowser.

Watching this was hardest on Luigi, this was his big brother, if it didn't end well he would lose him. Sure he would be the next hero of the Mushroom Kingdom, but for a green Italian man, losing his only true family, well that was worst loss of all. Luigi couldn't stand by any longer watching.

"Hey" Luigi yells "that's my brother." Kamek then suddenly appears in front of him, not knowing he was coming Luigi took a steps backwards, a rainbow smoke suddenly surrounded Luigi, everything went in slow motion after that for him, falling to his knees, then to the ground.

Mario, without knowing, manages to defended Bowser, in the tail and sent him flying in the air, he then unlock the cage and save Princess Peach.

"Oh Mario," she said, "thank you so much for saving me, what would we do without you?" the princess then kiss his nose as Mario blush.

"And thank you too, Luigi." She then notice that Luigi wasn't here except they heard a crying of the baby. Mario turn around and saw a baby crying.

Mario and Peach quickly come and saw Luigi as a baby. "Kamek must somehow de-aged him into a baby!" said Peach. "Maybe Rosalina can change him back!" Mario nodded as Luigi looks up at Mario with a big crocodile tears on his face, holding his arms out to her and whimpers wanting to be held. Mario picks him up "Hey Luigi" he says kissing his forehead..

In Peach's Castle, they are in the castle library. Mario's eyes go wide "So he basically will have to grow up again?" The blue princess simply nods.

"I'm afraid so, I don't know about this spell, it new to me, I never see this spell before. So I had to check thought ever spell books I had in my observatory library."

Peach looks at Mario then down at Luigi "What will he remember?" she asks not taking her eyes off him.

"Not much, only what a child that age would. Faces will be it, I can have him recognize you both" she motions to both of them.

"No" Peach says stopping her "just Mario."

"Peach, what are you saying, he needs to recognize both of us" Mario says.

"I'm aware of that Mario, but I think you can handle the baby, and beside, I have a books about baby." she takes Mario's hand.

"I can't Peach, there is no way I can raise him, I don't know about baby, I don't if he going to be a same the Luigi we know in love" tears where quickly filling Mario's eyes.

Peach gives him a sad smile "You have me and your friends to help, you can do this. I have faith that you can raise him well. He loves you Mario, and I know how much you love him, you can do this, I know you can, have faith in your heart Mario."

Mario looks down at Luigi, then over at Rosalina. "Alright, I can do this" he says with a teary smile at the two women.

"Ok Mario" Rosalina says, she takes the few steps over to Luigi "Luigi will recognize you Mario as his older brother; in his mind he will remember you as the one taking care of him up to this point."

Rosalina was about to change him then Mario says "Wait" he holds up his hand "what about Daisy? Luigi and Daisy are in the relationship, won't he need to remember her too?"

"Oh yeah, I forgot about Daisy" Peach says. She takes a second and said "but I know she cares for you and Luigi, so I will let her know what happen."

"Ok, here we go" Rosalina states. She waves her wand to Luigi, and she quickly magic's him in a diaper and green footie pajamas.

Luigi woke up and looks up at Mario with a big grin on his face, laughing and playing with his big nose. Mario chuckle "Hey Luigi" he says kissing his forehead.

And so, Rosalina went back to her observatory and Peach give Mario a book about babies. So then, Mario took Luigi home and he then unlock the door, turn on the light. "Well Luigi, look like it just you and me, how about we watch some shows before we go to bed."

Mario then put Luigi in his lap, and they watch a kids show on Television just as; The backyardigans, Barney, Wubbzy, Sesame Street, Wonder Pet, Toot and Puddle, Blue's Clues, and Rugrats. After they watch all the shows, Luigi fall asleep. Mario turn off the tv and went to the bedroom upstairs.

Mario wear his red pajama and put Luigi in his red bed. He turn off the lamp, he look at Luigi snuggle in his chest. Luigi yawn and he close his eyes and he snuggle and went to sleep. Mario look at his baby bro and give a small smile. He kiss his brother brown hair and went to sleep.
