New chapter!
Finn took Abadeer and relentlessly pounded him into the ground. Finn then took him and said,"By the way your daughter is great in bed." This angered Abadeer and he smashed Finn through a building."The pain! It feels so good!", said Finn. Finn lunged at Hunson and continued to relentlessly pummel him."I can't stand by and watch this!",said Marceline.
"No!", said Bubblegum, grabbing her by the shoulder."We need to approach this logically!"
"Fuck logic!",screamed Marceline. She rushed at Finn but was instantly swiped to the side."Stay out of this bitch!",screamed Finn. Jake caught Marceline and took her into the candy castle along with Bubblegum. Bubblegum rushed to the lab and unveiled a super laser."When did you build this?",asked Jake.
"The last time the demon attacked. I guess now would be a good time to use it."
"But won't it kill Finn?!"
"Jake I know you're concerned, but that's not Finn anymore."
"No! He's still in there!"
"Jake, I don't want to do this anymore than you do, but it needs to be done.", said Marceline. Jake nodded with a tear in his eye. Bubblegum started up the machine and Marceline yelled,"Dad get out of the way!" Hunson dodged the beam and it Finn head on. After the dust settled, Finn stood there with the energy surging through his hand."H-he absorbed it?!",Bubblegum said, shocked.
"It tickles!",yelled Finn. He then threw the ball of energy back at the lab."Get out!", yelled Jake. They ran out of the room as it burst into a fiery explosion.
"Now, back to business.",Finn said turning to Abadeer."This has gone on too long." Finn's arm extended into a blade. He had absorbed the sword, and it was now part of him. He attempted to slice Abadeer, but he vanished. Hunson appeared behind him, but Finn kicked him through a wall. He stumbled to his feet, tired and weak."That's the problem with you! You feel pain, you get exhausted, but I embrace the pain, and the longer I fight, the stronger I get!" Hunson would be able to beat him, but he didn't have enough soul energy to get through the fight. Finn took his sword and swung it as he could. Suddenly there was a clash of metal, and Marceline stood there with her axe bass, preventing Finn from striking her father."I thought I told you to stay out of this!",shouted Finn. Marceline swung her axe bass at Finn,but he dodged it and slammed her into a wall. He took his blade and put it at Marceline's throat."Stop this!",shouted Jake."Finn, please look what you're doing! You're hurting all these people, and you're about to kill your girlfriend!"
"But I don't want to stop."
"W-what?"
"It's so much fun. All this destruction and death, it's all so exciting!
"Y-you don't m-mean that! That's just the demon talking!"
"Oh believe me, I'm speaking my mind. These people don't care for me. The only reason they help me is because they're scared of what would happen if I turned on them, which I have." Jake stood there, baffled at what Finn was saying. Finn continued on,"These people wouldn't lift a finger to help me! Now they get what they deserve!" Marceline saw that Finn was distracted,and kicked him back. She rushed at him with her axe bass,but Finn swiped it to the side and grabbed her by the throat. He raised his blade and Marceline screamed"Finn no!" She closed her eyes waiting for the inevitable.
