"...Really?" He questioned. "I mean, I'm already overqualified. But hey, always up for a fight. Good or bad." He stepped through the portal, arms folded as he came through in...what was this place? He looked around, trying to figure it out--
"Hey! What do you think you're doing in this ring? Get out of here! This is a sacred fighting ground, not some tourist destination! Now get lost, before The World Champ makes ya!"
"..." He snickered. "Perfect." He pointed right at the champ.
"I hereby challenge this world champ! And once I'm done taking him out with ease...I think I'll have proved myself for your little contest."
"You think so? Well you cocky little amateur, I will show you what it means to be...THE CHAMPION OF THE WORLD--"
"Shut up."
"What did you say, you lil punk?"
"Just tell me who you are."
"Do you live under a rock? My name's Hercule Satan, C-H-A-M-P-I-O-N and--"
"Yes yes." He replied with a dismissing wave, done with that nonsense before smiling smugly.
"I'll be sure to write that on your grave." He took his stance, readying. "Come at me when you're ready."
*one extended beatdown later*
He gripped the unconscious Satan by the collar, the champ half slumping against the ground...make that fully, landing in a heap on the floor as Mercury let go, running a hand through his hair.
"Didn't even break a sweat. Hopefully one of you is more challenging."
