Hello readers this is my new AT fanfic it consists of both worlds it, includes my own original character Rhys the Demon king And his gender swap hope you like it

Marshall thought about the other universe and how this school was interdimentional. He had seen weird things at this school when his brother went here but now that it's him here he had mostly focused on the gender-swapped universe. He sat next to his best friend Bubba Gumball who quickly whispered "Who has an assembly the first hour of the first day of school"

"Yeah I know"

"This is so boring" there friend Riana said

As their first class started their teacher stood up he had a long shaggy beard teal blue skin and wore a tunic, a noticeable feature was his crown. "Hello class I am mister Petrikov" he said "are first activity will a partner activity will be assigning"

The class Groaned "Bonnibel you'll be with Marceline and Fiona"

"Finn you'll be with bubba and Marshall Lee"

"No wait let's make it boys vs. girls separate on to different sides of the room"

"JESUS" Rhys Screamed

"WHY THE HELL AM I ACCEPTING THIS" Rhys Screamed

"Rhys Finn Marshall and bubba detention 2 hours tonight" said the ice king (the kid's new nickname for him)

"Ugh thanks Rhys I had a date with Ashley tonight" Exclaimed Marshall

"Ashley, That girl is a bitch" replied Rhys

"I agree" the prince said

"Hey it's not nice to call someone a b- girl dog" Finn said avoiding to curse. Finn grabbed his sword and tossed towards Marshall. Marshall picked up the sword and merrily stabbed Rhys in the arm which faded away "How do you like my shadow-saber"

Marshall grabbed his sword and thrust into his chest. Rhys clenched his fist and bent over holding his chest. The three stared at Marshall in fear anger and awe.
