When the crowd was demanding an encore, Finn's eyes widened and he stared off in space. M.L noticed this and told Gumball. Finn then turned around out of the stage without a word and his band mates followed him, leaving the crowd dumbfounded.

Finn flew into the sky, and Marshall and PG followed him. Gumball borrowed M.L's phone since he forgot his and put it on silence so Finn wouldn't hear it and called Fionna. She said she and Marceline would come.

"No way," Marceline said. "But you have to! Finn leading them to PB!" Fionna protested. "Why do I have to come?" Marceline asked.

"I don't know. Just in case Finn's brain goes crazy and he tries to kill us, you'll probably be able to stop him. Cause you know, you're the queen of vamps." replied Fionna.

"But my brother's gonna be there," exclaimed Marceline. "Well maybe it's gonna take more than just him!" Fionna yelled irritated.

The argument continued for a while and Marceline gave in. The two were off to helping find Bubblegum.

Finn, Marshall, and Prince Gumball arrived at Rock Isle. Marshall and PG tried hard to not make a sound, knowing the slightest wheeze would blow their cover.

Then Finn faced a giant boulder with a figure on top of it.

That figure was Princess Bubblegum.

She was tied with rope coming from the giant rock and her mouth was taped shut. Marshall and Gumball were in shock.

"You're perfect bait as I suspected," Finn's voice was mixed with three different kinds: a hiss, a demonic growl and his normal voice.

"Your friends are already coming to save you. Although two of them are already here, Marceline and my sister are on their way."

PG and M.L's eyes widened.

They're cover's been already blown and they didn't even know it.

Then, spikes of stone formed around them and they were soon in a cave made of rocks. Marshall Lee tried getting them out, but he actually struggled and ended up failing.

"I don't get it," he said. "Why can't I break this trash?! I'm the Vampire King! Maybe of only Aaa and not Ooo but my powers still work regularly any place!"

Then they heard an evil laugh. "Ha, ha. You have no idea how weak you are against me, do you?"

"Finn, you need to stop this! You've gone brain crazy!" Gumball told him.

"Why? Just so you can make-out with your princess?" Finn made kissing noises at the prince, mocking him. Gumball's face turned red with rage and embarrassment.

"It's only a matter of time before you all die in my clutches! Starting with the princess…" Finn cackled and approached PB with his sword.

"No!" PG gasped and suddenly kicked through the cage and ran at Finn. Marshall was shocked at what he witnessed.

Bubblegum must be really important to Pinky, Lee thought as he exited the cage.

Prince Gumball tried to tackle Finn but Finn turned around and got his arm around Gumball's neck.

He back-fisted his face two times, swiped him to the ground and kicked his stomach. Then he picked the prince up by his throat and said,

"You wanna be with your love? Then go join here!" yelled the vampire as he threw the prince on the boulder with Princess Bubblegum.

"Snap out of it, bro! Don't let the tragedy of Marceline dumping you control you!" M.L told Finn.

"No one's being controlled!" Finn protested. "Marceline…don't you see? She's the reason were in this mess! If it wasn't for her, I wouldn't have captured PB, hurt PG or be a vampire trying to accomplish one goal…"

"What's that?" asked Lee.

"The Vampire Queen's destruction," Finn yelled and flaming rocked were shot at M.L.

He blocked them with his axe-bass except for two that hit his stomach and face that caused him to fall to the ground.

Finn grabbed his leg and smashed him against the ground multiple times until he zapped him with laser eyes.

"W-why does my strength feel…out ranked?" Marshall asked in pain. "You fool! You need to face that this vamp is stronger than you!" Finn said.

Lee looked behind Finn to see Gumball trying to untie PB and sighed. He need to stall Finn so they could rescue Princess Bubblegum and hope Fionna and his sister would get here soon.

Finn punched Marshall's face, grabbed his arm and broke it. Marshall hissed in agony. Finn smirked, and kneed Marshall hard in the chest. Backing away, Marshall coughed up blood. He felt his muscles grow weaker and weaker. His vision was becoming blurry.

Before Finn could attack again, he heard the sound of Bubblegum's shoes sliding off the boulder. Finn made hand signs and teleported behind PG. He kicked his groin and elbowed his stomach. He then began to make a series of strikes at the prince, and soon Gumball was laying on the ground on his back bleeding and suffering major injuries.

"Bubba!" PB gasped. Marshall attempted to tackle Finn, but Finn was too fast and grasped M.L's shirt collar…

"Bubba!" PB shook the knocked out royal male. "Bubbs! Can you hear me? Please! Say something! BUBBS!"

Marshall crashed into the boulder, unconsciousness consuming him. He slid down to the ground as Bubblegum noticed his bloody wounds. Finn neared her, his fangs bared. His claws started to get sharper. "You're next…" he whispered loud enough for her to hear.

"Finn!" exclaimed PB. "It's me! Princess Bubblegum! Stop this! You've gone cray-cray!"

Finn went to slash Bubblegum but missed by an inch when she ducked. "Don't let the painful memory of Marceline dumping you be consumed by the vampiric bloodlust!"

"SHUT UP!" Finn yelled and leapt at her. PB tried moving out of the way but Finn grabbed her arm. She struggled, "Unhand me now!"

"Sorry," Finn grinned. "No can do."

He punched her square in the face, and she fell to the ground losing much consciousness and sugar (blood). Some of her marshmallow teeth had been knocked out of her mouth.

Finn stomped on her stomach multiple times until she was gagging on sugar. He took her throat, strangling her, even when she wasn't conscious. Suddenly, an axe-bass flew towards Finn and cut his right cheek. He hissed as he turned to the attacker, "You…"

"The one and only," Marceline smirked as her hand caught her bass.

Finn growled, "Where's my stupid sister? I know she's here! I can smell her scent!" Finn sniffed the air, and furrowed his eyebrows, frowning with a disgusted expression on his face. "She smells like… sweat, alcohol and cherries?"

"Ugh, still?!" Fionna screamed in annoyance as she appeared behind Finn in a puff of snow. "I washed my clothes and took a shower seven times in two days!"

"That's the consequences for being with my bro, Fi." Marceline cackled. "I'm surprised you don't smell like his butt!" Fionna grunted in irritation.

"You should talk," Finn told Marceline. "You smell like strawberries, red wine, zombie poodle, and heroism!" Finn stuck out his tongue on the last word in disgust. Fionna couldn't help but giggle. Marceline's face became red. "Th-the heroism came from you, you doofus!"

"Correction: it came from the old goody-two shoes me. I am a new being now. I've been reborn…INTO SOMETHING BETTER!"

Lightning cracked in the sky at Finn's last phrase. Marceline bit her lip, trying hard not to let it quiver. "B-but…I never wanted you better, Finn…I loved-love you for who you are…" Marceline whispered. "Oh my gosh…I really do still love you!"

Finn approached Marceline, but Fionna blocked his way. "End all of this, brother!" she commanded him. "I don't want it to have to be this way!"

Finn sighed, "Neither do I, sis…"

He lunged at her, hissing with a demonic face and his claw ready to slice open her neck…

CHUNK!

A horrid, shocking, and mournful silence filled the area. Marceline gasped as tears welled in her eyes. "N-No…"

Finn growled. "Urgh…"

Salty tears ran down Fionna's cheeks. "M-Marshall Lee…"

Marshall grunted in pain as he turned his head to face Fionna. Blood oozed down the corners of his mouth. "Hey, Fifi…" Finn's claw in Marshall's in the border of Marshall's chest and stomach began to draw more blood.

"I don't have much time…" Marshall whispered. "No!" Fionna said. "You can't leave me! I won't let it happ-"

"Shh…" Marshall put a bloody finger on Fionna's lips stopping her. "It's too late for me, Fionna. Just promise me one thing Fi while I'm gone…don't ever forget me…"

Fionna shook her head, "Not ever, Marshy. I'll always remember you…"

Marshall smiled. "Thank you, Fionna the Human." Marshall's eyes began to close as Finn ripped away his hand from the vampire king of Aaa. "…And good night to you, my sister, my friends, and my fans…"

He fell to the ground with a thud, and Fionna ran quickly to him. His eyes were closed, and he was still and motionless. She kissed him, and blood covered her mouth but she didn't care and it did no good. Marceline watched silently crying to herself as Fionna bawled on her boyfriend's body.

"Good-bye, Marshall Lee the Vampire King…"

Well that may be the end of Marshall for the rest of this story. I don't know. Prince Gumball might die too. I was originally going to have Finn explain what really happened to Marce's pic of Hambo but I thought of this instead. So that might be explained in the next chapter. Maybe.
