Miraculous Crossover One-Shots

Really Bruce?

Got this idea from the Ao3 'Another one?' by AnjuSchiffer

~

Marinette is being trained by Master Fu on how to use the miraculous. She was training in Paris since her parents live there. She started training when she was 2. At the age of 4 Marinette is really smart. So one day when she was bored... she used Kaalki to teleport somewhere. That place just so happened to be the Batcave where a sleep deprived Tim was.

Tim was on the bat computer doing god knows what. Suddenly there was a bright light that lasted one second. When he turned toward that light he almost screamed. Standing there was a girl no older than 4.

"What the hell! Who are yo.... Oh god don't tell me Bruce adopted another one!" Tim groaned.

"Who are you?" Marinette spoke in French.

Tim looked at Marinette. "I am Tim. Who are you and what are you doing here?" He responded in French.

"I'm Marinette! I'm sorry to bother you. I was bored and Master Fu was busy and my parents don't ta- anyways I teleported here for fun!" Marinette then disappeared, she really just walked away to explore.

'Am I hallucinating? Maybe I should get some sleep.'

Tim decided to tell his adoptive father about it.

Bruce was just minding his own business, reading a book in the library, when Tim barged into the room followed by his eldest sons.

"DAD! THERE IS A DARK HAIRED, BLUE EYED, 4 YEAR OLD GIRL! IN THE BATCAVE! Did you seriously adopt another child?"

'Did I?'

"No...? Tim are you okay. How much sleep did you get!"

"ARE YOU IMPLYING I'M LYING? SHE LITERALLY POPPED UP OUT OF NO WHERE LIKE MAGIC. SHE SAID SHE WAS BORED SO SHE CAME HERE?"

"Replacement... you have got to be hallucinating." Jason said as he stared at Tim.

"Sorry bro but I'm with Jay. I haven't seen a 4 year old girl around here. Unless... B? Are you hiding something from us?" Dick then turns to his adoptive father.

'I don't remember signing the adoption papers for a new child...?'

"Nope. Never seen a dark hair, blue eyed, 4 year old around here." He then continues reading his book.

"Are you sure? I wouldn't be surprised if you were hiding a secret child behind our backs. She does fit the description. Only if she had a traumatic past." Jason said.

"Or maybe Tim is just hallucinating because he hasn't gotten enough sleep." Bruce said, not looking up from his book.

"I swear she is real! She is like magical or something." Tim argued.

"Like that coffee fairy you talked about the other day?" Jason laughed. Tim huffed.

"No I-"

"FATHER!" In came a grumpy 13 year old holding a 4 year old by her shirt.

"Damian! You don't hold people like that." Dick yelled as he rushes to the little girl.

"SEE! SHE IS REAL!" Tim screamed.

"Damian what is the purpose of this?" Bruce asks, setting his book down.

"This THING was playing with MY cow." Damian growled.

"I-I'm sorry! I d-didn't mean to! I was b-bored." Said a teary eyed Marinette. Damian scoffed.

"Hey sunshine don't cry! Damian is just being a grumpy cat." Dick said.
