The Multiverse Brawl

Tabuu: After Tabuu's defeat by the hands and claws of the trophy worlds mercenaries, he was lost in his own altered dimension. Rid of his wings, and his powers he was left with no options. But then, he saw a light, and he reached for that light. That light was the key to ultimate power. That light was a connection to a new dimension that would give Tabuu infinite power under one cost: To become mortal.

When he came to this new world, he came to one that was blank. It was a completely blank planet. Nothing but a white endless plain. But with his new powers, he had the power to create. He knew this was going to be different this time, he would be smarter this time. So he created a world of his own, with its own species; skeletons.

In his rule over the skeletons he got bored. He decided he needed some sort of sport to watch. So he created the Multiverse Brawl. But he was too lazy in his mortal form to take care of all of the preparations every single year. So he looked to the first chosen dimensions of the Multiverse Brawl and found, GLaDOS, Doculus, and Atlas.

Dimension Stories

1 The Heroes of Olympus:

2 Dimension 2: This world is a world of magic, mercenaries, and mingling between one teenager and a cat lady from another dimension. Throughout this teenagers years, he has been imprisoned by a king named King Engorged, rescued by a mage named Lelf, brought through a huge journey to bring along a bunch of random people to kill a demon who was beginning to destroy the balance of space and time, and found true love.

When Tabuu first looked at the dimension, he saw loads of magical power in it. He knew they would put up a good fight in the games. He went to find a good leader, but they did not have a leader. They were all divided into five regions. So, with his powers, he brought all of the leaders to his presence at once and threatened them to give out tributes to the games. They immediately agreed to his terms.

In this dimension, Tabuu found Doculus turned into stone and decided to revive him. In return, Doculus would make everything weapon/destruction related happen in the games.

3 Adventure Time:

4 Super Mario World: Tabuu had been in this world once before, but not like this. This was not the trophy world. It was just Mario's world. Tabuu already had enough information about this world, and he was going to destroy it.

With ease, he destroyed the Mushroom Kingdom and Desert Kingdom. All that layed before him was Bowser. However, this Bowser was different, he loved the ideas of the games, he loved Tabuu, he practically worshiped him. Tabuu took a liking to Bowser as well, so he asked Bowser if he wanted to join the games, and Bowser was happy to oblige.

5 Dragon Ball Z:

6 COD:

7 Halo:

8 Team Fortress 2:

9 Assassins Creed:

10 DC Universe: When Tabuu first arrived in this dimension, he was intrigued by the amount energy emanating from it. This dimension was perfect for the games. Thinking the most powerful being in this world was its leader, Tabuu immediately went to Super Man.

When Tabuu asked Super Man to agree to his terms, he said no. With that, the hardest fight Super Man had ever faced had begun. Super Man, along with his fellow meta-humans fought against Tabuu with much difficulty. Eventually this led to war between Tabuu's dimension versus DC earth.

Killing most of the Justice League's heroes, Tabuu prevailed in taking over DC earth, and making them part of the games. Most of the non-meta-humans like Batman, and Green Arrow, survived.

However, his job was not done yet, for Wonder Woman, daughter of Athena, fought against Tabuu along with the other Olympians. Except Ares, who took advantage upon the conflict and went to kill the Olympians himself. Ares was now satisfied, he was now the most powerful being in the universe.

Now that he ruled DC earth, he could start never ending conflict. Though this power was nothing compared to the fight with Tabuu. So when Tabuu asked Ares to give out tributes, he made a deal: He asked to link his power from DC Universe to Tabuu's dimension for the energy from the conflict. Tabuu happily agreed to his terms, and DC earth has been part of the games ever since.

11 Fairy Tail:

12 MLP-FIM: (Note: This is before the Mane Six were even born.) When Tabuu found this world, it was flowing abundantly with an incredible amount of magical power. He sensed a probable leader in the most unpredictable place he could think of (Sarcastically.), a city on the side of a mountain.

When he confronted Celestia, he was shocked to see the world was inhabited by ponies. He didn't really notice the species of the guards as he was killing them. But then he noticed.

When he asked for her to give tributes, she immediately said no. Tabuu then threatened to destroy the dimension. She didn't think he was serious at first until he ripped a hole in space to the void. Celestia attempted to use the Elements of Harmony, but to no avail. The beam bounced off of him like a bee to a window. With a bunch of pointless fighting, Celestia agreed to his terms. She could not let all the ponies die at once. Plus she panicked.

And then she cried in her pillow for the rest of the day.......
