A long time ago, there lived a boy named Harry Potter. He was a brilliant wizard who was in his fifth year of Hogwarts. He was studying for his OWLs, going over his notes out on the courtyard. Suddenly, a big red and black floating battleship came flying in the sky. Ron and Hermione looked up at the thing.

"Sorry, but the OWLs will have to wait." Harry pointed to the big thing. It shot a big red laser, destroying the Bell Tower of Hogwarts.

"We must tell Dumbledore!" Hermione alerted.

"We can't!" Harry replied. "Umbridge has replaced Dumbledore, remember?"

"Oh yes." A big red beam shined down from it, and from it came a short blonde-haired woman in a red robe with gold trim and golden laced high heeled shoes. The expression on her face with her ruby red lips meant that she was to be feared.

"Who are you, and what do you want with Hogwarts!" Harry yelled, pointing his wand at the woman.

"I am Aris Van Pandora, leader of a multiversal empire known as the Muspelheim Empire." She called to her battleship and her goons, which were robotic ninjas with laser guns started firing at Hogwarts.

"Um, excuse me, but Muggle technology doesn't work in the Wizarding world." Hermione told Aris. How does that thing work in Hogwarts?"

"This is no mere Muggle technology." Aris laughed. "This is tech engineered by multiversal aliens from the cores of the multiverse!" She drew her scepter and shot fire from it. Ron blocked the attack with his Protego spell.

"Diffendo!" Hermione yelled. The attack had no effect, because Aris absorbed it.

"Fool, Celestial magic is stronger than Earth Magic, so even an Unforgivable Curse will do NOTHING TO ME!" She used her staff to fire a laser blast at Harry, but a spiky haired duelist blocked it with his Waboku Trap Card.

"You look like someone who belongs to a British punk band." Harry reacted to the strange man.

"I am Yami Yugi, Pharoah of Ancient Egypt and King of Games." The spiky haired duelist announced. Ron and Hermione apparated to safety, while Yugi summoned Slifer the Sky Dragon.

"Jump on if you want to live!" Harry jumped on Yugi's dragon and escaped the crumbling Hogwarts.

"You haven't seen the last of me!" Aris shrieked.

"So, do you know anything about this woman? Harry asked Yugi.

"Apparently, this woman does have some connection with the origin of Duel Monsters." Yugi began to recall his past lives.

"Duel Monsters?" Harry gasped. "What's that?"

"It's a card game which my universe is based around." Yugi explained. "In one of my past lives, I was a Greek Senator named Atemus, and I knew someone named Pandora. She was the Greek Trickster Goddess. Perhaps Aris is a descendant of the Greek Trickster Goddess?"

"Well, whoever she is, an alien or a big-headed astronaut, we will give her a taste of justice, because she destroyed my beloved Hogwarts." Yugi and Harry flew away to safety, in hot pursuit of Aris and her evil army.
