More than one enemy? Tom and Marco's heated reunion!

"What are you doing here!?"

"Is that how you treat old friends?" Tom's mouth twitched with excitement, "Where's my warm welcome, pal?"

"Don't give me that bullshit, Tom," Marco's temper was beginning to flare, him just being here meant bad news for everyone, "We were never friends."

"Fine, have it your way then," Tom had begun walking up to Marco only to stop a foot away from him, "despite my appearance, I came here on business."

Before Marco could react, Tom had punched him in the stomach. The force used in the punch, clearly meant to kill a normal human, merely caused Marco to stumble back a few steps and dispense his breakfast on the ground. Tom's interest was peaked as he witnessed the mortal try to catch his breath.

"Seems like you can take a punch, I that's going to make this much more interesting than I thought." He launched himself towards the stunned target at a great velocity. Cocking his arm back, flames engulfing his fist, he threw a punch with much more force than earlier. As it was about to make contact with his target's skull, it stopped, baffling the demon.

"Huh?"

"I can do more than just take a punch." Marco had caught the fist in his hand, ignoring the burning sensation on his flesh, he started to squeeze until he could hear the crunch of bone. Before Tom could assess what just happened, he was now on the ground several feet away with a broken nose gushing out a black substance. The demon blood in Tom's veins allowed for it to completely heal as he got off the ground and brushed off the filth from the asphalt.

"You can throw quite a punch, for a human, that is." Tom started to stretch, preparing for the imminent battle.

"Before I stomp your ass, answer me one question," Marco got into his battle stance as he felt Tom's evil presence become more intense, "Why are you doing this now? Star isn't here anymore and doing this won't change anything between you and her."

"Dumbass, I'm not doing this for star, I guess you have no idea about the price on your head," he explained, "Two very generous gentlemen offered me quite a sum for the elimination of Marco Diaz of planet Earth. No questions asked, I accepted, Now I hope you can keep up with the King of Demons, lowly human."

They charged at each other and met in the middle, both throwing punches with incredible force causing an explosive shockwave as their fists collided. They stepped back, noticing the crater on the ground from their first real attack, sizing each other up before charging again in a flurry of punches, blocks, and kicks. The buildings around them trembled and windows shattered at their show of power. This battle would mark the beginning of something much more sinister.

"Goddamnit. Tom is a complete disappointment, not only was he unable to kill Marco Diaz swiftly, but he also gave him a clue as to our identity." Crius was fuming, red faced with a vein throbbing on his forehead. He slammed a fist down onto the table which had a monitor, the battle between the demon and human clearly visible.

"Well, I only see one way of fixing this problem, Crius", Goya cuts in on Crius's tantrum, "Specimen One should be sent out to take care of the situation, he seems more than capable of handling these weaklings."

"Intruders eliminated. Awaiting orders." A tall, bulky, man speaks out to the two scientists. He had slipped into the room undetected, he was soaked in a red liquid.

"Ah, Specimen one, I'm glad you could take care of those Mewni soldiers. It was extremely rude of them to try to infiltrate our base," Goya said, " I have some new orders for you. Go to planet Earth and see to it that you dispose of Tom, King of Demons. Also, subdue and bring back Marco Diaz, we're making our move now."

"Eliminate Tom, King of Demons. Subdue and retrieve Marco Diaz." Specimen One repeated before using his hand to slice open a dimensional portal.

"Your highness, there's suspicious activity going on in dimension 56-c, two dimensional portals have opened up there in under 24 hours," A military officer called out to the princess, "There also seems to be two large sources of life force energy emanating from a planet called Earth, this isn't looking good."

"I have a hunch this might have something to do with Marco, assemble a strike force and we shall leave for Earth shortly" Star declared in a voice filled with determination.

"As you wish, your highness" The man bowed and ran off to another part of the castle.

"HI-YAH!", Marco threw his arm full force towards Tom, the impact hit him full force as he was sent through several buildings. Marco winced as he just took note of his own injuries; Several fractured ribs, dark purple bruises all over his body, and a broken left arm that forced him to fight with only one arm. Tom however was in a much worse state, the demon had taken several attacks head on which resulted in a completely shattered ribcage and two extremely injured legs. A normal person wouldn't be able to move but Tom was beyond such mortal limitations.

Tom was running purely on adrenaline and sheer anger at the fact that a human could force him into a corner in a brawl. He got up from the impact crater, determined to end Marco in one final assault, but it would require a lot of energy from within. Demon Ki is highly powerful but unstable at times so he would need to concentrate it to a certain part of his body and launch the attack from there. Tom slowly made his way back to where Marco was by flight, for both his femurs were badly fractured.

"Marco Diaz, I applaud you for putting up such a brave effort against me," Tom's index finger was slowly being surrounded by black electricity, which he hid behind his back, "but I think it's time to end this silly fight and take your head with me" He landed some distance away from his target.

"You'll never defeat me, Tom! Just give up now before I have to kill you" Marco braced himself for the oncoming onslaught.

Tom's attack was now ready to be launched, in a moment Marco will be dead, his eyes glowed red as a dark aura seeped out of his body giving him a sort of glow.

"Now witness my DEATH BEAM-!" He paused as a portal was ripped open in between the fighters.

They watched in confusion as a man stepped out and looked over the two of them. His eyes flashed as he analyzed the condition of their bodies and energy left.

"Targets found...Commencing attack mode."
