It started off as a normal day for Aelita. After completing a day of school, she and the Lyoko Warriors decided to head to Lyoko to investigate a digital signature, believing it to be a possible XANA attack. But as they investigated the digital signal, it became clear that something was off. When Aelita arrived at the digital signature, Aelita suddenly found herself in a dark room. Aelita looked around, trying to figure out where she was.

Aelita: Jeremy? Jeremy!

Aelita only got silence. At this point, Aelita became deeply concerned. Suddenly, Aelita was approached by a tall, slender woman with ivory skin, pointed ears, maroon lips, and golden eyes. She had long, untamed gray hair and a gold tooth.

???: You too, kid?

Aelita: I'm....I'm sorry, but do I know you?

???: You don't know me? Eda the Owl Lady? The most powerful Witch in the Boiling Isles?

At this point, Aelita became even more confused. Suddenly, a ray of light was shined on her and Eda. Aelita and Eda look to see five others. Another light soon falls on a large table with 6 individuals.

???: Aelita Schaeffer. Edalyn Clawthorne. Alucard. Samurai Jack. Itachi Uchiha. Obi-Wan Kenobi. Goliath. You have all been summoned by the Tribunal. I am Arygyn, Guardian of Atmos. The are my colleagues Ozpin: Headmaster of Beacon Academy and reincarnation of Ozma, Dr. Liara T'Soni: Asari Scientist and Shadow Broker, Yoda: Grandmaster of the Jedi Order, Gandalf: Wizard and Protector of Middle Earth, and Iroh: Dragon of the West and Grand Lotus of the Order of the White Lotus.

As Arygyn introduced himself and the Tribunal, there was a moment of silence. After a moment, Obi-Wan was the first to speak.

Obi-Wan: Master Yoda? What are you doing here?

Yoda: Your Yoda, I am not.

Eda: Okay, I'll bite. I'm sure this is the part where I find out this is some kind of elaborate illusion from Belos and this is also the part where I bust out and give him and the castor of this illusion some serious black eyes!

Itachi: This is no illusion. At least...I don't believe so.

Ozpin: You are right, Itachi Uchiha. This is no illusion. What you see is very real.

Aelita: Why....why are we here?

Iroh: We should tell them.

Yoda: Agreed. Deserve the truth, they should.

Samurai Jack: What truth?

Arygyn: As some, if not all of you believe, your worlds is the only one that exists. However, each of your worlds is but one of countless worlds that spans the infinite Multiverse. The Tribunal is tasked with maintaining the balance and stability of the Multiverse.

As Arygyn said this, Aelita and the others showed varying degrees of shock. It wasn't long before Goliath stepped forward.

Goliath: There is a reason that you have summoned us. What is the reason?

Arygyn: As we speak, the Radio Demon Alastor and interdimensional arms dealer Black Hat are embarking on a deadly game.

Ozpin: Black Hat is an interdimensional arms dealer that provides products and services to Villains across the Multiverse. It's most likely that Black Hat has done business to the Villains in your respective worlds in some way, shape or form.

Gandalf: A former serial killer in life, Alastor is notorious entity in Hell and one of its many overlords. Alastor has also been known to travel across the Multiverse and make deals with people in exchange for their eternal souls.

Iroh: And it just so happens that these two are....intense rivals.

A projection of Black Hat and Alastor was shown to the group. To some, they had never encountered such terrifying beings. But Alucard soon began laughing.

Alucard: Is that all? Why not let these two Demons kill each other.

Liara: It is not that easy, Alucard. If Black Hat and Alastor are left unchecked and allowed to play their twisted game, it could destroy the boundaries between all worlds across the Multiverse and cause them to collide with each other, destroying them and everyone in them. Your worlds would suffer that fate.

Yoda: Stop Black Hat and Alastor, you must.

Aelita: But...how are we supposed to stop them.

Liara: We have searched the Multiverse to assemble a task force of the finest the Multiverse has to offer. We believe you all capable of stopping Black Hat and Alastor before their game destroys the entire Multiverse.

As Liara said this, Aelita felt an immense weight on her shoulders. She had just been tasked with stopping two interdimensional beings from destroying the Multiverse. The lives of trillions upon trillions were in the balance. After a moment, Eda speaks up.

Eda: This just might be the craziest thing I've ever done. But I'm game.

Alucard: This should be....amusing to say the least.

Goliath: If the lives of innocents hang in the balance, then I will do what I must to save them.

Samurai Jack: You will have my sword.

Obi-Wan: The Force brought us all together for a reason.

With that, Aelita soon found the courage to step forward and embark on this journey. Despite not knowing what was ahead of her, she at least wouldn't be alone.

Aelita: I....we won't let you down.

Arygyn: The task ahead of you will be difficult, but we have faith that you will rise up to the challenge.

As Arygyn said this, he and the rest of the Tribunal raised on hand, creating a road of brilliant blue light.

Arygyn: Follow the road. It will take you where you need to go.

In that moment, Aelita and the group set out on their mission to preserve the Multiverse. The mission to stop Black Hat and Alastor had begun.
