I just imagine if Jaune have Big Mom as her aunt.
.....
Team RWBY and JNPR in class with no Jaune.
Ruby: "Oh hey guys. Where's Jaune?"
Yang: "Yeah, is VB coming late today?"
Pyrrha: "He said he had to make something at the kitchen. It sounded urgent so we didn't want to bother him."
CRACK!
The grounds began to shakes, as books falls to the ground. Students quickly take cover under table.
Ruby: "W-What's happening!?"
Yang: "Is it a Grimm attack!?"
Blake: "An earthquake!?"
Unknown woman voice: "CROQUEMBOUCHE!!!"
Weiss: "What. Was. That?"
Ren: "Whatever it is, the sound seems to be near."
CRACK
Unknown woman voice: "WHERE IS IT!?"
Oobleck: "Class dismissed. Everyone, please get to safety!"
Blake: "It seems to be coming from Emerald Forest."
Nora: "Wanna go there?"
Yang: "You bet."
Both team quickly went to Emerald Forest. Then they saw the source of the voice and shaking. A large woman, wearing a pink dress who was tearing through the Emerald Forest and coming towards Beacon.
Large woman: "Croquembouche! Where is it?"
Nora: "T-That's Big Mom. She's a well known figure on Mistral."
Yang: "So who is she?"
Pyrrha: "Big Mom. She is a former Pirate, inactive Huntress and current largest producer of sugar of Remnant!"
Weiss: "Any reason to why she is tearing through the forest and making way to Beacon while shouting croquembouche?"
Ren: "I heard about it but never seen it. This is apparently one of her Hunger Pangs, a condition where she is hungry and begins to search for a specific dish and won't calm down until she eat said food."
Blake: "In this case, its croquembouche."
Grimms began to come at Big Mom and surrounds her.
Big Mom: "Annoying pests! Get out of my way!"
Big Mom throw away Beowolves, squished Ursa with her hands and tore apart King Taijitu.
Nora: "She just squished the Grimm!"
An Elder Goliath was now in the way of Big Mom to Beacon.
Big Mom hug squished the Elder Goliath before making her way again to Beacon.
Beacon Tower,
Headmaster Office.
Glynda panicking as she saw Big Mom almost to the tower.
Glynda: "Ozpin, what are going to do? She's almost here!"
Ozpin: "I already contacted James for help but the fleet won't be here for at least another 2 hour."
Glynda: "There won't be much of the Academy by then."
Ozpin: "I suppose but I do wonder why Big Mom is here."
Ding.
The elevator opens and Jaune rushed out.
Jaune: "Out of the way!"
Jaune was carrying a large croquembouche with him while heading to one of the glass window.
Glynda: "Mr. Arc! What-"
Jaune opens a window and jumps out to Big Mom.
Glynda: "Mr. Arc!"
Jaune: "Look over here." *Jaune use Aura Burst to leapt in the air.*
Big Mom turned around to Jaune.
Big Mom: "Huh? Don't get in my way!" *Clench a fist and throw a punch at Jaune. Jaune dodge it.*
Jaune: "Eat this!"
Jaune toss the large croquembouche into Big Mom's mouth which the large woman slowly but surely swallow.
The students and teachers of Beacon Academy watch with worried look as Big Mom swallow and eat the large croquembouche.
Big Mom fall to the ground, her face change from hungry to happy.
Big Mom: "It's delicious!"
The students and teachers let out a sigh of relief.
15 minutes later.
Jaune: "So this is my aunt, Auntie Lin-Lin."
Big Mom: Hello everyone.
RWBY and JNPR: *Worried gaze.* "Hello."
Night.
Jaune: "I managed to make her go to sleep. Before we go to sleep, anyone got questions."
Yang: "Yeah, we do."
Ruby: "Is her semblance something that made her big?"
Jaune: "No, she was involved in an experiment by one of Atlas Scientist which caused her large figure."
Nora: "She's really your aunt?"
Jaune: "Yeah, she's married to one of my uncle."
Weiss: "I can't believe the Headmaster is okay with your Aunt sleeping at Beacon."
Jaune: "I believe the word of the Vale councilor was 'Better Beacon than Vale'. Makes sense, the don't want the city to fall to her Hunger Pangs."
Pyrrha: "I heard the headmaster have allowed you not to attend class so that you can focus on ensuring your Aunt full and happy. Is this true?"
Jaune: "Yep, Professor Goodwitch wasn't happy but needs must."
Blake: "Speaking of your aunt, the damage that she needs to pay must have cost a lot."
Jaune: "She's also very rich. Maybe below SDC but only because of her Hunger Pangs attack. In any case, she need a lot of food for her body and has the money to pay for any damage she caused."
Ruby: "She's that rich?"
Jaune: "She got her own several private islands. Her main island is called the Whole Cake Island. I actually learn some cooking from that island."
Ren: "Anything else you want to tell us before we all go to sleep?"
Jaune: "I promised to make her red bean soup and a chocolate chip cookie before she go back."
