The Conqueror's Return

After walking down a dark and cold passage, they have reached their destination. Hunson and Flame Princess have arrived in the PIT which located at the outer core of Earth. It was like the Fire Kingdom but has more lava and fire flowing around. The demon used his power to pull out the nine prison cells from the ocean of molten magma and placed them all on solid rock. Before he unlocks them, he faced the fire elemental and asked her again. "Are you sure about this, princess? Releasing these nine terrorists is a cosmic crime and you will cause death and destruction to all Reality. Are you ready for this responsibility?"

Now that he mentioned it, Flame Princess was unsure if she could do it. Committing a cosmic crime. Causing death and destruction to all Reality. Not a single being is crazy enough to do this. She has some second thoughts.

The nine prisoners looked at their savior, the one who could free them from their cells. They started to whisper to her, making her do what they wanted her to do. "Free us."

"I can't." Flame Princess said. "I can't do this."

"What did you say?" Hunson pretends that he did not hear it but hearing her answer just made him smile big. "What did you say again, princess?"

"I can't do it. This is too much."

With her answer caused a powerful uproar from the nine prisoners. "FREE US! FREE US! FREE US!"

Then, a massive shock wave was heard above them, above the PIT. Hunson can feel five souls heading to their direction. Five souls, familiar and strange. The ceiling of the PIT explodes and those five souls that the demon felt dropped and landed in front of them. Flame Princess covers her face from the rock and dirt while the prisoners continues their screams for freedom.

"Who dares invade my kingdom?" Hunson transformed himself back to his monstrous and hideous demon form.

"It's them." Flame Princess lights up her fire sword and prepares to face the counterparts.

Prince Gumball, wearing PB's suit, leads the attack. "Stop her before she releases those prisoners!" Fionna, Marshall and the Flame Prince leaps towards their enemy with their own weapons. Then Marshall Lee and Hunson were surprised to see each other. "Whoa!" But then, Hunson's army of demons and Flame Princess's army arrived and joined in. Both armies thought Hunson and Flame Princess began to fight each other and so they fought for their superiors.

Fire elementals versus demons.

The battle between the two groups has gone intense.

On the distant reality, Finn, Jake, PB and Marcy were given a tour around the Land of Uuu by the Flame Kid. He showed them the tree house which was owned by the savior of the land. "Now you see the home of Uuu's most beloved hero, Finn the Human, who sacrificed his own life to save our world from the Lich Titan."

The curious Finn raised his hand, has a question in mind. "How did he defeated the... uh, Lich Titan?"

"Oh, it was an awesome battle. He used the cube and slings it towards the Lich Titan's head. That caused a massive reality explosion and the monster and the human disappeared in the bright light. Some theories about Finn's survival stated that he and the Lich are still alive but they are trapped inside the cube. Princess Bubblegum and her team of extra-dimensional experts are trying to figure out how they free Finn."

PB felt ignored by the kid. He did not recognize her as a counterpart. So she asked the boy, "What is the princess looked like?"

The boy answered with a creepy smile. "Oh, she's beautiful. Her bubblegum hair is gorgeous and sweet. But her new form was a little out of place. Not a good match with her hair color."

"What do you mean by that?"

"A year ago, she tried to make a perfect clone of Finn. However, one of experiments exposes her and her bubblegum body replaced with human bones and flesh. She has become half-human after that."

"Uuuhhh..." The princess made the same reaction before. Her eyes twitched after hearing her counterpart's back story.

Jake suggested, "We should think of something how to get back. Man, I can't imagine what's going on back there. Lady must be worried sick right now."

Marceline has an idea. "How about we meet this Princess Bubblegum? She can help us. Hey, kid, can you take us to the Candy Kingdom?"

"Sure. Follow me."

After the tour, the kid showed them the passage to the Candy Kingdom. He pulled a lever from the candy trees and opened the tunnel which leads underground. He sets up a torch and leads the way. The five arrived at the kingdom heavily guarded by Gumball Guardians and has taller walls than the ones at Ooo. The kid pulls out his trumpet from his backpack and blows it hard. The sound of the horn echoed and the candy people knew who it was. They threw a large welcome party. "The Prince is here! Hooray!"

The gates opened and the candy people immediately approached the boy but they rudely ignore the four who were with him. Finn, Jake, PB and Marcy were just shocked that they were ignored by many. The kid turned to them, giving one last instructions before celebrating with his friends. "Meet the princess at the castle. The password is Pink is much sweeter than Red."

Marceline got an awkward look to Bonnibel when they heard the password. The two women looked away from each other while Finn and Jake remembered the password. "Okay. We will be on our way." The four proceeds to the castle where they will meet the only person who can take them back home: Princess Bubblegum of Uuu.

Back to the Land of Ooo, the Ice Queen guards the dungeon where the only prisoner was locked up. Simon creates snowballs and threw them to the wall with boredom. He wondered why his beloved blond maiden locked him up. He thought they are having a great time when she jumped over him. He sighed with sadness and then questioned to reality. "Oh, why can't I get a princess?"

Hearing his words, the Ice Queen can feel the same way. "Hey! Don't feel bad. I don't get a prince too."

"Really? Is it really hard?"

"It is. Gumball did not see how much I loved him. He keeps on ignoring me. He only pays attention with that human girl Fionna!" Ice Queen expresses her hate to her arch-nemesis, shooting her ice bolts everywhere. Ice King calms the lady down. "Easy there! You might hit the lock and freezes it. If that happens, I could break it and escape."

"Well, you are right. I must be careful." The pale lady sat down and tries to take some little meditation.

Simon thinks of something that can calm her nerves. "I can show you something that might help you relax."

The Ice Queen turned to him with a suspicious look. "Alright. Show me this 'something' and I might release you here."

"Okay!" He showed her his smile which was nasty and innocent at the same time.

"But promise me that you will return to your prison cell when they come back."

"I promise." Ice King crossed his heart and raised his hand, making a sign of promise.

Flame Princess has taken care of her counterpart, pushing him to the river of lava and washed him away. Now it was Fionna's turn to attack the fire elemental with her crystal sword. "You'll regret this, princess!"

"You're the one who is going to regret being here!" Flame Princess dodges the crystal blade and then makes her attack.

Fionna easily blocks the fire sword with her own and pushed the princess away from her.

Hunson and Marshall Lee have some conversation while they were fighting. Marshall Lee makes a powerful strike with his guitar axe however, his attack was stopped by Abadeer's impenetrable demon skin. "Okay! Answer this! What did you take from my counterpart's meal?"

"Her fries?"

"Oh, mine's a big burger."

Prince Gumball and Cake were trying to get out from the battle between the demons and the fire elementals. Cake commented, "Whoa! This is chaotic!" The prince agreed with her, "Indeed. Our mission here is to stop the princess from releasing those terrorists."

The prisoners screamed even louder, chanting their word. "FREEDOM! FREEDOM! FREEDOM!" One of the nine remained silent and waited patiently for the battle to end. He sat down and watched the chaos outside his cell. He hides his dark tendrils for it was not the time to use them. He waited in the shadows of his cell.

"Psst." One of the nine called him, "So, what do you think? Do we get a chance?"

The dark entity nods, made sure that they will be free.

Fionna and Flame Princess made their fight mighty as their skills in combat were tested. Fionna's skill of using her crystal sword and Flame Princess's ability to shape and control her fire. The fire soldiers and the demons saw the glorious battle between the powerful women that they have ever saw. But their fight caused more destruction around them. Prince Gumball can see that the Flame Princess's flame almost hit one of the cells. He looked at his device and analyzed any probabilities that might set those prisoners loose. After scanning, the device showed the prince that there is a 90% probability that it will happen.

He approached Cake, "You must stop Fionna!"

"Why? She is in her zone! She loves this kind of fights."

"You don't get it! Her fight with the Flame Princess has a probability that can release those prisoners!"

But his warning was too late. Fionna make a big leap to the princess and swings her crystal sword. Flame Princess also swings her fire sword and clash it with the crystal sword. The two swords collide and caused a strong spark of power. And that spark struck all the locks of the cell and opened all up. Cake was surprised to see those nine prison opened that easily. "How is this possible?"

"The locks are indestructible. No mortal blade can break it. They can only be unlock my the demon who used them. However, those locks are weak with emotion sparks."

"What is an emotion spark?"

"It is a powerful force when strong emotions, like rage, clashes. Fionna and the Flame Princess puts on their rage in their attacks and caused this spark."

Cake saw the cell doors opened and the nine strange-looking figures came out. "Um, now what?"

Everyone in the PIT paused as the nine prisoners, who once threaten all Reality, came out and revealed themselves to them. The fire soldiers, Flame Princess, the counterparts, the demons and the Lord of Evil were shock and afraid to see them free and begin their quest to conquer all Reality again. One of them showed his sinister grin, made of hell fire. "It's show time."
