Chapter 3

Finn's POV

Finn wasn't surprised by the blade arm, and the armor wasn't much of a stretch. What really surprised him was the fact that Alex's speed had at least doubled. He was across the room before Finn could raise his sword. Finn found himself staring at the point of Alex's blade, held in the air by his throat.

Alex momentarily dropped his armor and gave Finn a cold glare, "I suppose I can't blame you, after all, I did try to kill you. Well, let's get this over." he told Finn.

Finn suddenly found himself falling as Alex's hand separated from the rest of his arm. Finn was confused for a moment, but the he remembered, Marceline had gone invisible. He'd have to thank her after this fight was over.

Finn then had to scoot backwards quickly as Alex's blade arc toward him while he sat on the ground. Finn barely managed to avoid becoming minus one leg. He then sprang to his feet, sword swinging. his blade met Alex's, whose armor was back. Finn was at least relieved to see that Alex's left arm was gone. Then Alex's left hand punched him in the face.

Alex's POV

The boy he'd been fighting flew backwards across the room. Alex then placed his foot on his severed hand. The hand melted and the biomass rejoined his body. Alex then turned his attention on the other people in the room.

The old man and dog had taken the time he and Finn had fought to encircle him. The pink girl had disappeared, probably running for help, or to save her own skin. The dog began to advance, while blue light began to shine in the old man's hands. Alex switched over to his claws and attacked the dog. the dog had some strange powers, he kept shifting and changing shape. Alex would be fighting him in one place, and get hit by a giant fist from behind.

Next eventually the dog changed tactics, surrounding Alex in a dome of orange, pelting him from all sides. Alex swung his blade left and right, but no matter where he swung the dome would move away from him in that direction, and slam him from behind. Finally Alex jumped into the air, the dome stayed in place, as Alex had hoped. He grabbed the dog dome and twisted it. The dog screamed in pain, and he kicked it to the side of the room.

Then everything went cold.

Finn's POV

Finn blinked his eyes open, shaking the dizziness from his head. He scooped his sword up and leapt to his feet, to be greeted by an unexpected sight. Alex was frozen in a block of ice. Bringing the Ice King in to help had been a smart move after all. The princess was gone, but she was probably safe. Finn went over to talk to the others.

Jake sat to the side nursing a few bruised ribs, though largely unharmed. Finn walked over and sat down next to him.

"Hey Jake," Finn said, "what happened?" Jake smiled and said "I started kicking his buns, until he threw me. Then the ice king froze him." Finn scanned the room "where's Marcy?"

Finn's question was answered by a pinch on the arm and a disembodied voice saying "What am I, invisible?" Then the grey skinned vampire girl slowly faded into view. "Nice to see you awake again sleeping beauty." she said sarcastically. Finn blushed slightly, "Hey, Marcy." "Yeah Finn?" "Thanks for the save back there. That guy would have taken my head off." Marceline smiled and gave him a light punch on the shoulder, "Any time Finn."

Suddenly a loud cracking sound filled the room and everyone was pelted with chunks of ice. Alex Mercer stood, free from the ice. He glared everyone in the room and said,

"Round two"

Alex's POV

Alex leapt into the air, and cut the cord holding the chandelier in place. It came crashing to the floor, lighting on fire, which left only a small circle of light to see by. He then stood upside-down on the ceiling, a little trick he'd perfected while locked in the vault. From here he was completely hidden, and used this opportunity to survey his opponents. He saw the two adventurers, and the old man standing on the floor, huddling near the fire. For a second he could have sworn there was a fourth person, a girl he hadn't seen before.

When he once again felt a heavy chop to his back, he realize three things. One, the girl was, and had always been there, just invisible. Two, she somehow could see in the dark, like he could. Third, somehow, she could either walk on walls, or fly. Alex then got an idea. He switched his vision over to the thermal spectrum and took a look around.

He could see three people around one bright spot. The rest of the world was light blue. Then he saw a dark blue, humanoid shape raced towards him. It swung something towards him, and Alex formed his blade and blocked. Then he began to truly battle.

Finn's POV

Finn stood in the light of the flames, Jake on one side, Ice King on the other. Marceline was somewhere in the shadows, invisible, using he night-vision to fight their hidden enemy. The clashing of weapons filled the air, as the two invisible forces clashed. Somehow Alex had found a way to detect Marcy.

Suddenly a wet chopping sound is heard, the sound of a heavy blade hitting a person. Blood rains from the void in a thin stream, forming a grisly pool at the edge of the firelight. Finn held his breath in anticipation. Marcy must have gotten a hit on Alex. The sound of the fighting had stopped.

Then something fell.

It hit the ground with a thump. This was it. The fight between Alex and Marceline was over.

It was Marceline's axe.

Alex walked into the firelight, dragging Marceline's limp form behind him. He lifted her up for them all to see, and threw her towards them. She had a large stab wound in the stomach, the blood on Alex's blade leaving no doubt about what had caused it. She wasn't moving, save for a few faint breaths. They had to end this fight quickly.

Or Marceline would die.

Then, as if the answer to a prayer, a bright warm light shone behind Alex. A single candle, burning against a black background.

She'd gotten his call.

Several hours ago

Finn picked up the phone, dialing a number he hadn't called in weeks. Ever since they'd broken up, and his girlfriend, the Princess of Flame, had taken over her father's kingdom, they hadn't talked at all. On one hand, he didn't want to put her in any more danger, but on the other, she was the one of the most powerful people he knew. He needed her help.

The phone began to ring. Finn waited.

"Hello," a bored voice said, "this is the receptionist for the Flame Queen, how may I help you?"

"Yes this is Finn the Human speaking, I'd like to speak to the queen."

"Thank you for notifying us, we will relay your request and send a reply in a few months."

"WAIT, THIS IS AN EMERGENCY!"

"What kind of emergency?"

"The kind that could threaten all of Ooo! We need the queen at the Candy Palace."

"Thank you. We will send this to the Flame Queen at some point today and she may or may not be able to help. Have a nice day."

The total honesty law that the new queen had imposed in the Fire Kingdom could get annoying at times. She would probably not come, but he had to hope she would help.

Present

Now here she was, dressed in golden armor that swirled like magma. She surveyed the scene, and almost immediately seemed to understand what was going on. She raised her hand, and a large fireball formed over it.

Alex's POV

Alex was ready to finish them. If he couldn't get information through cooperation, he'd just consume them and get information that way. Then suddenly his eyes, still on the thermal spectrum, noticed an increase in temperature. He slowly looked behind him, and was blinded.

Switching back to normal vision, he saw that the source of the incredible heat was a girl, about fourteen or fifteen. She gave off light, and heat, as if she were made of fire. then she tossed a fireball at him. He sped out of the way, barely avoiding a nasty burn. Then he jumped up to the roof again.

Alex knew he couldn't fight her head on, so he tried another unorthodox tactic. He switched over to his hammer fists and, taking full advantage of being mostly invisible, started hammering away at the roof above her head. Soon it began to fall, and he jumped clear of the rubble as it fell. Soon it was just a pile of rocks where she once stood. Then he leapt back on top of the pile, and face the others.

"Is there anyone else I should know about?" he asked sarcastically. The three remaining people had looks ranging from fear, to concern. He then began to notice the floor heating up below him.

The a tower of white-hot flames incinerated him.

Hmmm, didn't feel all that strong in some parts, let me know what you think.
