I have talked to my team of advisors and after skimming through the internet, our movie collections and a few other odds and ends here and there, they think it'll be a good idea to write a monster Marco story…yeah, totally original, we know, but they gave me a few suggestions and I think you guys might like it. Enjoy the first chapter.

Star Butterfly and her parents Moon and River stood in the main foyer of the Butterfly castle while Moon and River talked to various guests. Star groaned in annoyance and looked out the window and spotted the Forest of Certain Death in the distance. She looked at her parents and saw their backs were turned towards her. She smirked as she tightly held her newly required wand and snuck out of the foyer.

Star walked around the forest and looked around, "I'm glad I got away from the castle. I would've died of boredom if I stayed," hearing a twig snap, she looked back and saw a boy around her age with brown hair, wearing a red hoodie, "What are you doing here? This place is crawling with monsters,"

"Yeah…that's why I'm here," Star looked confused and the boy coughed, "My name's Marco by the way…I uh…I really don't know how I got here,"

"Um…Star Butterfly and why do you mean by that?" Marco shrugged his shoulders and Star frowned, "So…are you here hunting monsters or what?"

"Nah, I don't think it'll be a good idea to hunt my own kind." Star's eyes widened as she held her wand out and it began to glow, "You hunt monsters?" Star narrowed her eyes and Marco sighed, "Good, kill me, kill me and end my suffering!" Star looked confused and Marco cried and shook his head, "Please just…just kill me! I don't want to carry this curse anymore!"

Star sighed and put her wand down before slowly walking up to Marco, "What are you talking about? Aren't monsters ruthless killers?"

"I don't know what monsters you know, but…where are? We're nowhere near Echo Creek, and I don't know anywhere on earth that has a forest dedicated to nothing but monsters and…"

"Earth? You mean you're not from Mewni?" Marco looked at her in confusion and arched a brow, "You claim to be a monster…you look pretty normal to me,"

"I'm not…I don't even know what monster class I'll fall in…I don't know…I don't know," Star frowned and placed a hand on his back, "Kill me…please just…just end my suffering,"

Star shook her head, "Why don't you tell me what happened? Why are you calling yourself a monster?"

"I…it's…hard to explain…I was with some of my friends…and then…all of a sudden…two…two creatures jumped out from behind the bushes and started fighting with one another. In my group of friends was this girl that I liked named Jackie and I didn't want her to get hurt, so I pushed her back and then I felt a sheering pain in my back and my neck and…"

"Whoa, slow down, I can't keep up," Star sighed and Marco frowned, "Why don't you tell me what happened after you felt that pain,"

Marco sighed and nodded, "I felt my insides fighting…each organ trying to tear another apart and then…I started growing fangs, claws, fur, my ears started to point upwards…my eyes flashed yellow and red…as it turns out…the creatures were a vampire and a werewolf…mortal enemies…and I got the venom from both of them coursing through me…tearing me apart!" Star's eyes widened and Marco began panting, "I can't sleep, I can't think…I can't do anything without the venoms fighting with one another!" he grabbed his head and howled in pain before falling to the ground and hung his head as he cried.

"And…and what of your friends? Did they offer any type of…?"

"They went home…I thought they were going to get help…no…they were looking for ways to kill a hybrid…they wanted me…they wanted me dead!" he began panting again before letting out an unsettling howl.

He continued to cry and Star knelt beside him and rubbed his back and he looked up, "How did you end up on Mewni?"

"I…I don't know…I saw a black portal and I figured…this will kill me and end my suffering. I jumped through it, saw several monsters roaming around and I thought I died and gone to hell,"

"Well…you're not in hell, you're on Mewni," Star frowned before standing up and helped Marco up, "C'mon…you look like you can use a shower and a nice meal."

"You…you're helping me? But why? I thought you were going to kill me,"

"Marco…while it is true I come from a family of monster haters…you really haven't given me a reason to hate you. I can see that you're scared and alone…and from the sound of it…you can use a friend right about now," Marco looked at her in confusion, "Well…I used to date a demon, so I think I can befriend a monster like you,"

"Used to?" Star frowned and nodded, "Um…if it's not too much trouble, what happened?" Star bit her lip and Marco looked down, feeling ashamed, "I uh…I'm sorry, I just thought since you're being nice to me, I can try and be nice to…"

"He…he tried to force himself on me," Marco's eyes widened and Star rubbed her arm, "I wasn't comfortable doing that. I tried to tell him, but he kept persisting. I broke up with him, kicked him where it counts and left,"

"Do you want me to rip his entrails out," Star looked at him, wide-eyed and Marco sighed and shook his head, "I…I'm sorry, that wasn't me, that was the werewolf venom." Star nodded and Marco frowned, "Are you sure you want to invite me to your place. You said so yourself, your family hates monsters and I'm not exactly in control of the venoms,"

"I won't let them hurt you," Star assured with a small smile Marco frowned and nodded before the two of them turned and started walking back towards the Butterfly castle.

Okay, enjoy the first chapter. I've noticed there are vampire Marco stories, I think I'm the only one who wrote a werewolf story and now I decided to add both into one. This is rated for a list of reasons my advisors don't want me getting into right now. Please enjoy everyone and please let me know what everyone thinks.
