Hey guys! I'd like to know what you think about the characters. (Badass, douch bag, misunderstood, etc .). So let me know what you think in the reviews! If I get enough reviews, I'll make a chapter on Jeff's origins!


Finn could literally feel the energy coming off of Jeff. It was immense, even more than his. Suddenly, in a flash, Jeff had thrown Finn out through the ceiling of the Tree Fort and catapulted him into the ground outside. The ground shatred around Finn as he slammed into the Earth. Jeff had come down on top of Finn, driving him further into the ground. Finn kicked Jefferey off of him, but Jeff sprung back up as soon as he touched the ground. Finn climbed out of the small crater in the ground. "This could actually be a challenge.", Finn said confidently.

"You have no idea.", Jeff responded. He threw a energy ball at Finn, but he dodged it. Jeff had intented him to. He rushed at Finn and delivered a crushing blow to his stomach, sending him flying back. Jeff appeared where Finn was headed and kicked him upwards. He appeared in the sky and swiped him back down to Earth. Finn slammed into a rock, and it shattered around him. Jeff flew down at Finn, but he caught Jeff and launched him at an old building. Jeff slammed through it, and it collapsed around him.

Finn approached the rubble to find Jeff, impaled on several large, thin slabs of rock. There were three going through his upper body, one in his leg, one on each of his arms, and one...directly through his brain. "Oh well then. I thought I'd be the one to kill you, but it looks like the building did it for me.", Finn said, chuckiling.

"Not dead yet.", Jeff broke the spikes and swiped at Finn, causing him to fly back. Finn stood up, "How are you still alive?! Even I wouldn't be able to survive that!"

"What can I say? I'm indestructible.", he responded.

"Anthing that walks can die, and I'm happy to prove that."

"Well then I guess you're no exception." Jeff blasted Finn directly in the chest, knocking him down. He grabbed Finn by the hair, brought him up, and slammed his head back into the ground. "You stupid...little...shit...you don't...know...the first...thing...about combat!", Jeff said between slams. Finn was out cold, and his body changed back to normal. Jeff's glows faded away, and he regained his composure.

He dragged Finn back to the holding cells where Princess Bubblegum was waiting. He opened the doors and walked in. "Oh my god! What happened to you two?!", Princess Bubblegum questioned.

"My job.", Jeff responded. He tossed Finn in a cell and activated the force field. "Now, what did you want to tell me before I left?", Jeff asked.

"Oh...I...Well, you're not the only one with the last name Mertens."

"What?"

"Your brother is alive."

"What?! Where is he?! Princess Bubblegum pointed at Finn. Jefferey's face went pale. "Jeff?", Princess Bubblegum sounded concerned.

"We've got one hell of a sibling rivalry to work out.", he responded sarcastically.
