you appear in a hellish scenario similar to that of Mortal Kombat, and I appear in front of you

In front of you appears Shaggy, but somewhat distorted and monstrous, with his forearms are separated with only 3 fingers on each hand, his pants are more of an orange color and appear distorted or with blurred motion, and there is a design that resembles a face on his shirt. He has the visible half of his face looking manic, and I find myself standing on his face taking control of it (the left half being white with a mask with an orange-red horn, my eye is yellow pure and has a mouth with fangs). His head and arms also appear to be separate from the torso and float on their own. If one can notice, there is a mouth print on the shirt of this possessed and manic Shaggy

"HEHAHAHA. SURPRISE!!!! REALLY THANK YOU!! I can finally FEEL. I missed reality so much... I'm just SO EXCITED. I've been very busy WORKING AGAIN!! I was CONQUER SOME UNIVERSES!!! ...Not with this universe of course, I wouldn't wanna leave you without a home!"

crouching erratically

"Hey hey hey, did you know... That I might be a little too strong for my own good??? Fighting a buncha so-called super powerful bings is starting to get a little boring so uh. OH YEAH. The red one put up quite the fight!!! I thought I'd lost everything I worked up to but a streak of luck hit me and I WON!!!"

"By the way, remember, I only have 3 earth minutes, if I stay here too long SOMEONE might catch me... Why did you contact me? Do you want one of the 3000 rap battles? That's what I promised!!"

"Oops, I think I rambled for a little too long. I also lied about the 10 years it would take for each one(I think), how about another RAP BATTLE?!?! YOU LOVE THOSE. This would be the second!! Oh maybe this time you'll be up for a REAL BATTLE!!!! (something like that)"

twisting my head upside down

"Just remember that I'll have to contain a small fragment that I have again, or else it would be... TOO EASY"

"Alright, here we go!! Let's BATTLE!!!! HAHAHA"
