My Name Is Lex

Princess Bubblegum entered her room, tired of almost a whole day of royal duties. From managing simple matters like breaking up a fight to huge things like the grand opening of the Candy Kingdom Museum, Bubblegum's day has been unusually busy. At first, she thought she'll retreat to her beloved science lab, but she changed her mind and went straight to her bedroom. She was going to change to her pajamas when she heard a knock on the door. Lazily, she approached the door and opened it. Outside, there is Peppermint Butler holding a phone.

"A call from Finn The Human, your majesty." He said as he politely handed the phone to her. "Thank you, Peppermint Butler." PB thanked. Peppermint Butler bowed before leaving. Princess Bubblegum closed the door before answering the call.

"Hello?"

"Hey Princess Bubblegum."

"Hey Finn, did you like the birthday party?"

"Heck yeah! And you'll never guess what I found after you guys left!"

"What is it?"

"So, after the party, Jake and I are out adventuring when we found..." PB listened closely, "... another human!"

That statement caught PB completely off guard. She thought it was gonna be something stupid and trivial, but she was completely wrong. "A-A-Another human?!" PB asked in shock. "Yeah, and he's a boy, just like me!" Finn exclaimed. PB remained in shock as Finn told her everything he knows about the human. PB snapped from his shock and promptly said, "Can you, Jake and the human come here first thing in the morning?"

"S-Sure, we'll try." Finn answered. "Okay, thanks." PB said before ending the call.

"Another human..." She muttered. PB's brains are completely blown away. When PB found out that Finn is a human, she was shocked as well but she considered that as plausible. Now there is a second human, the chances are beyond microscopic. Many theories came to her head as to why another could've survived the Mushroom War and why Finn can simply found the human. Suddenly, she doesn't feel so tired at all.

-At the Tree House-

Finn is a bit confused to why Peebles hung up, but Finn shrugs it off. "Did you tell PB about Lex?" Jake asked behind him. "Yeah, and she wanna meet Lex first thing in the morning." Finn said.

Finn looked around the room and said, "Where's Lex?". "He went upstairs to get ready for bed." Jake answered. "Remind me to get a bed for Lex, I don't think he like sleeping on the couch all the time." Finn said. "I will, and we should get ready for bed too." Jake said and with that, they went upstairs.

-Tomorrow morning-

Princess Bubblegum waited anxiously at the gates of the Candy Kingdom, keeping her eye fixed on the horizon. She could barely hold her excitement when they arrived. PB almost let out a scream, but she managed to keep it down. As they came closer, PB gulped. Finally they are now in front of her. Two of them she quickly recognized as Finn and Jake, her friends. But, she is more intrigued by the third one. The other human.

The human is about the same height as Finn, with red eyes and black hair. He's also wearing clothes similar to Finn, but his shirt is red and his pants are black. He's also not wearing a hat or a bag.

"Hi PB." Finn greeted. "PB, this is Lex, Lex, this is Princess Bubblegum." Finn introduced.

"Princess?" Lex said before bowing and said, "Pleased to meet you, Your Tallness."

"Lex, it's your highness not your tallness." Jake corrected.

"Oh, right. Sorry Princess." Lex said while scratching his hair.

"Jake and I've been teaching him how to talk, but he keeps mixing up words that means similar." Finn told. "You just found him two days ago and now he knows how to speak?!" PB said in disbelief. "Not only that, he's also starting to train with Finn about swordplay." Jake added. "Wow, he's one quick learner." PB said, amazed. "Thanks, Princess." Lex thanked. "Shall we enter?" PB asked and Finn nodded.

PB ordered the guards to open the gates and they entered. Once inside, Lex is amazed of the kingdom. "Remember Lex, don't go on an eating spree, the Candy Kingdom need less of that." Finn reminded. "I remember Finn. Don't eat anything that can talk." Lex sighed. "Here," PB chipped a piece of candy from a nearby building, "try it.". Lex took it, sniffed it, licked it and finally, he ate it. "That tasted great!" Lex exclaimed. "Well, shall we continue to the Candy Palace?" PB asked. "Yes, please." Jake answered.

As they walked towards the palace, Lex noticed that the Candy People are eyeing him. "Finn, why are the talking candy staring at me?" Lex asked. "Because we're humans, and humans are pretty rare." Finn answered. Before long, they arrived at the Candy Palace. "Whoa, that thing is huge!" Lex exclaimed.

They arrived at the door and Princess Bubblegum knocked on it. Shortly, the door is opened by Peppermint Butler. "Welcome back, Princess." Peppermint Butler welcomed. Pep But's eyes landed on Lex and he said, "Ah, you must be the other human. Welcome to the Candy Palace, sir.". "Please, don't call me sir, my name is Lex." Lex said. "And you must be... Peppermint Bun." Lex guessed. "Oh no, my name is Peppermint Butler." Peppermint Butler chuckled. "Oh yes, sorry." Lex apologized.

"Peppermint Butler, can you give our guests some drinks while I get my stuffs?" the Princess politely asked. The Butler simply nodded and left. "Peppermint Butler will return with some refreshments, now if you'll excuse me." PB said before she left. After a while, Peppermint Butler returned with three glasses of orange juice. The three gladly drank it.

Shortly after, PB returned with a needle and a small pouch. "Lend me your hand, Lex." She said and Lex complied. Suddenly, PB stabbed the needle to Lex's hand, making him yelp a bit. "PB, what are you doing!?" Finn shouted, concerned for Lex. The needle started to change color, from silver to red. Once the needle is completely red, PB removed it from Lex's hand, leaving a small hole. PB poured a drop of liquid from the pouch to Lex's hand and the wound healed instantly.

"What did you do to me?" Lex asked as he held his wrist. "I just took some of your blood, that's all. I'm gonna use it to run some tests." Peebles said as she put the needle and pouch in her pocket.

"Is that all, Princess? Because, we have somewhere else to go." Finn said. "Where are you going?" PB asked. "To Marcy's place." Jake answered. "You're going to Marceline's? Wait here." PB said before she left.

A few minutes later, she returned with a small box. "Give this to Marceline, okay?" PB said as she gave the box to Finn. "I will Princess." Finn said before he put the box in his backpack. "Goodbye then." PB waved her hand. "See ya, Princess." Jake said as he walked out the door.

"Now, on to the testing." PB happily smiled.

-Near Marceline's Cave-

"Hey, where is Marceline's house anyway?" Lex asked. "It's in a cave around here." Finn answered. "Is it that one?" Lex pointed at a cave nearby. "Yep, that's the one." Finn confirmed. "Nice spotting, Lex." Jake complimented. The group ran to the cave.

"Yo Marceline!" Finn shouted as they entered the cave, but what they saw inside completely froze them. The cave is filled with skeletons. And they can still walk. The shout that Finn made caused the skeletons to turn their attention to the group. Strangely, the skeletons didn't attack or anything, they just stare at the group. After a while, they turned their attention from the group to Marceline's house. Slowly, Finn reached for his Demon Sword. He grabbed the hilt and slightly pulled the sword out of its sheath, making a noise that is barely audible. However, the noise was enough to make some of the skeletons to turn their attention back to the group and go on the offensive.

The group reacted quickly. Finn unsheathes his Demon Sword and held it both of his hands, Jake enlarged his body and his fists and Lex, not knowing what he was supposed to do, put on a slightly awkward battle stance.

Finn started slashing his sword with powerful, one hit kills. Jake backed him up with smacks from his fists and stomps from his feet along with other attacks from his stretchy body. Lex is not very productive with bringing down the skeletons, mostly because he's unarmed and not used to hand-to-hand combat. Because of that, the skeletons surrounded him. Seeing that he's surrounded, he yelled to Finn, "Finn, give me the wooden one!".

Finn reacted quickly. He reached to his backpack and pulled out a wooden sword. He threw the sword to the air and Jake smacked it toward Lex. Lex jumped and caught the sword and as he landed, he managed to hit a skeleton right at its neck, severing its skull. Now that he's armed, he barraged the skeletons with a flurry of weak, but fast attacks. The three managed to defeat the skeletons that are attacking them and turned their attention to the skeletons near Marceline's House.

As they fought, Lex noticed that there is a girl with black hair and pale skin fending off the skeletons with a red axe at the roof of the house. One of the skeletons caught her off guard and pushed her off the roof. Lex immediately ran to her rescue. Lex caught the girl just before she hit the ground, but Lex didn't know how heavy the girl is, so Lex fell to the ground and made the girl fall on top of him.

The girl's face is now just inches away from his and this made Lex have a funny feeling. "Uuuuhhhhh..." is the only sound that escaped Lex's mouth while the girl's face showed a confused look. Suddenly, the girl stood up and raised her hand, her axe flying back to her hand. Immediately, she did a circling slash that defeated the skeletons surrounding them. She did another wide slash that fell many skeletons.

The girl noticed Finn and Jake fighting in the distance. "Finn! Jake! Over here!" The girl shouted at them. Finn and Jake heard the girl's shout and Jake immediately catapulted Finn towards the girl. Finn landed right next to the girl. "Marceline, what's going on?!" Finn abruptly asked. "I'll explain everything later. Right now, can you clear a path from here to my house?" the girl promptly said. Finn grunted, disappointed with her answer, but he still called out to Jake to clear a path. Jake did it by stretching his leg to a lane and stomping it down. Jake then made a hole, transforming it into a makeshift tunnel.

"Thanks, Jake." Marceline said as he ran through Jake's feet. When she got to the door, she didn't waste time opening the door, she broke down the door and entered. Jake stretched back to his regular form and started fighting again. Finn and Lex fought again, back-to-back.

"So I guess that was Marceline, huh?" Lex said as he struck a skeleton.

"Yep, she's the one and only Vampire Queen." Finn said as he blocked an attack.

"She looks pretty." Lex slashed a skeleton.

"Pretty?! This is Marceline we're talkin' about!" Finn cut a skeleton in half.

"So what? Everyone can have their own opinion. I heard you said that." Lex dodged an attack and retaliated with a blow to its head.

"I guess you're right. But, just wait until you actually know her." Finn struck down two skeletons at one swing.

Suddenly, all of the skeletons stopped moving. They all fell to the ground and crumbled to dust. Seeing that the battle is over, Finn put his Demon Sword to its sheath and Lex put his wooden sword in Finn backpack.

"What do you mean by 'wait until you actually know her'?" Lex restarted the argument.

"Look, all I'm saying is that you should know a person's personality before you judge their appearance."

"I'm not judging. It's just my first impression of her. And my first impression is that she looks pretty good."

Their argument is interrupted when Marceline showed up at the door. "Whew, glad that was over." She said. "Marcy, what the heck just happened?" Finn promptly asked. "It's nothing, just a summoning spell gone wrong." The Vampire Queen casually answered.

"By the way," Marceline asked back," What are you two arguing about? Who's pretty?"

"You are." Finn nonchalantly answered. "Who said that?" Marcy asked again. "I did." Lex answered with a blush on his face. "Thanks." Marceline giggled. Marceline then began to observe Lex. "So, you're the new human, huh?" Marceline said as he observed Lex. "Lex, right?" She asked and Lex nodded.

"Marcy, what was that?!" Jake joined in. "Summoning spell gone wrong." Marceline answered. "Thank Glob we came here or maybe you could've got croaked!" Jake said in relief. "Actually, I'm doin' pretty fine without your help, but still, thanks for the help." Marceline said. "Well, guess we should go." Finn said. "Already? Don't you want to play some tunes or something?" Marcy offered. "Nah, we still got to visit LR and FP next." Jake said.

"Oh yeah," Finn reached for his pack and pulled out a small box," PB asked me to give this to you.". "It's about time, Bonnibel." Marceline said as he received the box.

"Well, bye." Finn said as he walked towards the exit. As the group is about to exit, Lex turned around and waved at Marceline, which in turn waved back. Lex then exited the cave, impatiently waiting for their next meeting.

-At the outskirts of the Fire Kingdom-

After their visit to Lady Rainicorn's house, which is uneventful compared to their visit to Marceline's, they went on to the Fire Kingdom, to meet Flame Princess.

"Finn, are we supposed to go in there?" Lex pointed at the Fire Kingdom. "It looks pretty hot in there." He said. "Don't worry Lex, Flame Princess is going to meet us here instead." Finn informed, much to Lex's relief. The group stopped and waited for Flame Princess to arrive.

Before long, a streak of flame came from the Kingdom and stopped next to the group, the flame materializing into Flame Princess. Finn smiled at his girlfriend and she smiled back, but Finn can sense that FP is feeling down.

"What's wrong, FP?" He asked.

"Nothing, it's just that, my dad wanted me to have a bodyguard. Even though he let me choose who my bodyguard is, it still meant I won't be as free as I used to." The Princess frowned. "Hey, don't frown, you won't look as beautiful as you used to." Finn said which made her flame go brighter. "Besides, whoever this bodyguard is, I'm going to tell him or her to back off!" Finn proudly announced and made FP giggle.

"By the way, how long till you're physically stable?" Finn whispered. "Four more months." FP whispered to his boyfriend. "Man, I can't wait till that happens." Finn mumbled.

"Hello Flame Princess." Lex suddenly joined. "Oh, you must be Lex, the other human." FP greeted," It is a pleasure to meet you."

"I hope you turned out to be a hero like Finn." FP smiled. "Trust me, I'm going to be WAY better than him." Lex grinned. "Don't count on it." Finn chuckled.

"We meet again, Finn The Human." A voice from the sky said. The group looked up to see an old man with blue skin, a really long nose and a beard. He's wearing a blue tunic and a crown.

"Is that the Ice King?" Lex asked. "Yeah." Finn sighed. "What do you want, Ice King?" Finn said, slightly annoyed. "I want revenge because you ruined my moment with Engagement Ring Princess! Now, I'm going to ruin YOUR moment with Flame Princess." Ice king said with a laugh. "Dude, you can't kidnap Flame Princess, she's made out of fire." Jake said. "I know, that's why I'm going to freeze her first BEFORE kidnapping her." Ice King said which made FP gasp.

"Say WHAT?!" Finn yelled in anger. Ice King proceeded to shoot an ice bolt at the Princess, but Finn deflected it with his Demon Sword. Ice King shot more ice bolts but it either misses or got deflected by Finn. Jake enlarged his fists and charged them at the Ice King but the Ice King froze his fists. He proceeded to freeze Jake's whole body.

"Too cold to stretch..." Jake shivered.

Enraged even further, Finn jumped high and aimed his sword at Ice King's neck. However, Ice King created an ice shield and blocked the attack. The Ice King knocked Finn away, disarming him in the process. Finn landed harshly on the ground, his sword landing near him. Finn ran to his sword but Ice King shot an ice bolt at it, freezing it. He proceeded to laugh over his victory over Finn and Jake. But, he forgot about Lex.

Finn could feel something being pulled out of his bag. When he turned around, he saw Lex holding his wooden sword and he gave Finn a nod. Immediately, Finn realized what he's going to do and readied his hands. Lex jumped at Finn's hands and Finn gave him a push up. The Ice King, who is still laughing, is caught by surprise when Lex swung his sword right at his head, removing the Ice King's crown but breaking Lex's wooden sword too. Lex landed gracefully on the floor while Ice King landed with a thud.

Ice King looked up to see who his attacker was. "Eh? Who are you?" He asked in confusion. "My name is Lex." He announced proudly. Ice King observed Lex closely. "Impossible," He stared in disbelief, "another human..."

Suddenly, Ice King is pinned to the ground by a giant hand. The hand turned out to be Jake's hand, unfrozen thanks to Flame Princess. "It is possible, boyyyyy." Jake threatened, "'Now, there's gonna be TWO heroes guardin' the princesses, so you better back OFF!"

Ice King tried to grab his crown but Jake saw this so; he grabbed the crown and threw out of sight. Jake then let go of Ice King, now that he's not much of a threat. Ice King quickly ran towards the direction of the crown, while yelling, "I'll get you back someday!"

"Man, I did not expect THAT to happen." Finn said as he picked up his Demon Sword, that is now unfrozen.

"I don't think ANY of us is going to expect that." Lex added.

"Dang it, after that stunt, my dad's surely going to give me a bodyguard." FP grumbled.

"Hey, didn't you hear me back then, whoever's that bodyguard is, I'm gonna tell the guy to scram." Finn comforted and made FP smile again.

"I think I should go back." FP said. The couple shared a hug, before FP transformed into a streak of fire and entered the Fire Kingdom.

"Guess we should head back too," Jake stared into the sun, that is now starting to set, "it's gonna get dark soon.". The others agreed. The trio headed back to the Tree Fort.

Wow, Lex is falling for Marceline already? And what will PB's test reveal? And who's gonna be FP's bodyguard? Read on to find out!

PS. I'm really not good at author notes, so next time I did a short note or didn't do it at all, sorry.
