What's good everybody, TheAwesomeCoolJay is back at it again and that means I must entertain you all, once again. So in today's chapter I introduce a fan favorite from the show. Now the show's creators said they couldn't get this guy's return to work, but TheAwesomeCoolJay decides he's going to stay for the long run. Also to let you know this chapter will heavily be influenced by the movie Venom. Hopefully this guy doesn't try to eat anyone this time.

It was the weekend and Marco was in a good mood as he walked around in Echo Creek. The boy walked down the sidewalk happily thinking about the past events, mostly about the events that had him be important. He bested Hekapoo and got his own dimensional scissors, he defeated another member of the Magic High Commission with Star, and tomorrow he and Jackie will be together at the skatepark.

"Diaz you are on fire!" Marco praising himself.

Continuing his walk, Marco would soon hear screams from a female coming from an alley he was next to. A situation like this, the boy would pull out his phone and call for help but things were different now. He had more confidence and better skills now, and in mind Marco knew he could handle any problem Earth could throw at him.

"Now it's time for someone to catch this heat!" He said running towards the action.

Making it to the scene, Marco hid by a nearby trashcan and watched what was going on. It was indeed a lady screaming, the reason she was screaming, there was some scruffy looking homeless man trying to steal her purse.

"Somebody help!" The lady screamed.

"Come on lady, you knew the risk of walking down a place like this!" The thief explained as continued to pull the purse from her hands. "Just make this easier for both of us!"

Seeing how both hadn't notice him yet, Marco quietly took the lid off and planned out everything he was about to do next. The boy hopped out of his hiding spot and threw the lid towards the man. The lid had hit the man's head, causing him to release his grip, seeing his opponent stunned Marco ran towards and did a flash kick to the man's face.

"Nighty night!" The boy said getting his right hand ready for the knockout.

Marco did an uppercut but for some reason he didn't connect, but when he looked up Marco got that taste of reality again. His arms were to short reach the man's face and things got worse when the homeless man recovered.

"You stupid brat!" The older man angrily said as he kicked Marco away. "Okay lady just give me th-"

Pepper spray went into the muggers eyes, that brief moment he had with Marco gave the woman enough time to reach in her purse and get her pepper spray. The homeless man screamed in pain as he ran away. With him gone, the lady walked over to Marco to check if the kid was okay.

"That was brave of you kid, but you need to know your limits."

"Y-Yeah." Diaz said, not very satisfied with his performance.

Later that day

Marco visited Star's place and in the royal backyard the kids were there playing around with the latter's wand. Currently the princess was blasting herself and Marco's hair with the wand to see which style of hair looked better.

"Keep the pigtails?" She asked while touching her hair. "Or start rocking a ponytail?"

"Do whatever Star."

"Aw come on, I need feedback from someone who has pulled off a ponytail before."

TheAwesomeCoolJay: Remember I did do a chapter about the Saint Olga school and Miss Heinous... Could this be a foreshadow for next chapter though?

"I don't know just pick one." An aggravated Marco replied.

"Okay Mr. Grumpy, if you don't want to talk hair, what do you want to talk about?"

"Sorry Star, today wasn't my day." He said to her in a more calm down tone.

"What happen?"

"There was a guy trying to take a lady's purse, he didn't get the purse because of but he got away because of me."

"Don't beat yourself up on this Marco, at least you stopped him from getting the purse." The princess trying to comfort her friend.

"Still I could of handled that guy, I have the skills but I lack the muscle." Marco explained as he looked at his arms. "When I get older I'll be great, but I can't spend most of my time being a weak joke."

"Marco Diaz, you are not weak joke." Star told him as she grabbed his face and brought it close to hers. "You are already great, and you can be even greater with some magic by your side."

"You really would give me some kind of power or special ability!"

"Well we are best friends, and I plan to do what's best for you."

With that said, Star released Marco and walked over to a bush in the backyard. She began searching inside the bush, Marco was confused to why she did this but would get an answer when Star pulled out the Book of Spells from the bush.

"Why is that-"

"I use it to fool my mom, she thinks I'm studying back here." The young Butterfly giggled.

TheAwesomeCoolJay: Oh Star, you can't be trusted.

Laying the book down and flipping through the pages, Star was confident that she could find the right spell to help Marco. The boy was happy that she was helping him, but was a tad bit worried that Star was just randomly flipping through pages, instead of reading about the spells.

"Ooh here we go." Star, finally founding a spell. "This one is from Great-great-great-great Grandma Crescenta."

"You sure it will work?"

"Crescenta Butterfly created over 5,000 spells, so one of them has got to work."

"Okay, but let's thi-"

"Releaseo Demonius Infestica!"

Star shot the spell towards Marco's right arm and the magic began to do it's work. At first Marco was scared, but he felt a tingling feeling and suspected some form of super strength coming to his arms. Excitement was what the boy was feeling now, but shock came when his saw his arm change to a long, slimy, blue tentacle.

"Star?" A horrified Marco squeaked.

"I'm sure it's harmless." Star hoped.

"I will eat the bowels of my enemies!" The new arm shouted.

"And it talks."

"Yeah that's an evil arm." The young girl said getting her wand ready. "Don't worry I can fix this."

"Wait!" Marco quickly spoke as he put his normal hand in front of the tentacle. "Maybe he can be taught, maybe I can help him understand who his enemies are... and not get him to eat bowels."

"All right, but if things go bad you better hope the spell I use on you is painless."

"Whatever child just let me have my fun." The arm replied, while having a big grin on his face.

Later that day... again.

Walking down the same place in town, Marco expected things to different if he saw that man again but things just felt different having a living tentacle for a hand. Speaking of said tentacle, the monster looked around and saw some of the people walking by. Naturally they were curious or weirded out by such a sight, but the monster arm drooled from seeing things he refer to as prey.

"So many snacks, so little time." Monster Arm chuckled.

"Dude, I vouched for you to stick around so can you please stop looking at my kind as some sort of appetizer."

"That was your mistake, I'm not a nice guy."

"If that was true why didn't you eat my bowels then?" The boy asked.

"We share this body dummy, if you go down I go down."

"Then that makes us partners."

"You're a puppet and I hold the strings."

Before Marco could say something back, the boy saw the homeless from earlier and felt like this was a perfect situation to get Monster Arm some good boy points. Marco quickly but quietly followed the man from behind.

"This looks like the same alley, but there's no way the same lady would-"

"Help!"

Looking back in the alley, Marco saw that it was the same lady in the same situation with that homeless man again.

"You came back again lady, you must want me to take that purse!" The man said trying to take said item away again.

"Oh give me a break, this is my only shortcut to home and work!" She complained.

TheAwesomeCoolJay: The lazy excuse for not driving

"Okay round 2." Marco confidently said getting up from his hiding spot. "Hey mister, it's past your bedtime!"

"Oh not again." The man sighed, recognizing the kid's voice again. "Listen brat if you don't get out of here, I'm really gonna-"

The mugger was silenced when Marco's new arm wrapped around him and slammed him multiple times towards the wall of a building. Seeing that their opponent was defeated, Monster Arm brought the man down and pinned him against the wall.

"That was awesome, I mean ma'am are you okay?"

"Freaky boy, help!" The lady screamed running away from the scene.

"Your welcome." A deadpan Marco replied as he put his attention back on the mugger. "As for you-"

"Lunch time!" Monster Arm announced as he wrapped up his victim.

The homeless man's skin went very pale when he heard that, he even began to sweat profusely when he saw the sharp, yellow, dull teeth. Opening his mouth, Monster Arm was about to feast on this human, but something kept him from doing it. He questioned it for a moment, but remembered he wasn't alone. It was Marco who was holding him back, since the two shared the body they had to agree do something together or be at odds with each other.

"Let me eat!"

"No, we won already!" Marco told him as he kept resisting Monster Arm

As the two of them argued, the homeless man was able to wiggle out of the grip of the tentacle. Once he was free, the man ran for his life, both Marco and the Monster Arm saw this and this angered the latter.

"Great, now you are going to starve me!" Monster Arm accused the boy.

"Look if you're hungry I can help with that."

Later at Emilio's Pizza

Leaving the restaurant, Marco watched as his new arm was enjoying the last slice of pizza. Slurping the last slice, the Monster Arm let out a burp and appeared to have a smile.

"See pizza is better than bowels."

"Debatable... but that food was delicious."

"Hey there Diaz." A familiar female voice greeting the boy.

"Oh no." The boy groaned when he recognized that voice. "Hey Janna."

"Whoa is that a new arm, it's cool." Janna examining the tentacle.

"Is this one your other half?" The arm asking Marco.

"Oh boy."

The next day

At the skatepark, Marco and Jackie were having a great time skating, even if Monster Arm was acting as a third wheel. Marco was actually learning a lot, so much so that Jackie thought Marco was ready for the big ramp. The boy to see the ramp and was surprised to see how big it was.

"You sure that's for kids?"

"Totally dude, just watch me use it." Jackie told him as she heads towards the ramp.

"She is cool." Monster Arm commented.

"Yeah that's Jackie." Marco happily said about her.

"Not just her, everyone you introduced me too." The tentacle said thinking about yesterday too. "That other girl, your parents, and friends treated me like I wasn't a threat."

"See it's cool to be accepted than feared right?"

"Whatever, lets just watch her skate."

Looking back at Jackie, the girl made it to the big ramp and proceeded to skate down it. Going off the other end, Jackie was now in the air and tried to do a trick but she ended up losing her footing on her skateboard. She was going to hit the ground but this was prevented thanks to Monster Arm stretching out and catching her in the air and safely putting her down.

"Thanks for the save dudes." She tells both of them, but notices her board going somewhere. "I'll be right back."

When she went away to go find her board, Marco looked at Monster Arm with a goofy look.

"What?"

"Knew you had some good in you." The boy telling his new arm.

"I don't want to hear this."

Monster Arm decided to revert himself back to Marco's normal arm, once he did that Marco was at a loss of words at that moment.

"Wait Monster Arm you could do that this whole time!?" Marco shouted to his now normal hand. "Hello Monster Arm are yo-"

Monster Arm would quickly return and it looked like he had a frown while looking at Marco.

"Okay if we are going to be partners, can I get an actual name?"

"Oh okay, let me think."

"And it better be good."

"I got it, Eddy." The boy naming his partner.

"Eddy, I like it but why?"

"Because I'll need you ready for anything."

"That was terrible... but we will be ready for anything." Eddy agreeing with his partner.

And that's the end, hope you all enjoyed it. Now Mons- I mean Eddy is with Marco now and makes the boy more useful in combat and plus funny interactions in future chapters. Besides that, Marco could be seen differently by some people, anyway onto the preview.

Ludo is going through the land of Mewni and he has been seeing familiar and new faces. His wand, however, is making him make choices on how to deal with them. How will things be handled?

That's eerie and also next time, so until next time R.F.F. (Review Favorite Follow) PEACE!
