Mayuri smirked as the poisonous vapor surrounded him. Of course the poisonous part didn't affect Mayuri. He burst some dust off his shoulder and laughed. "Is that to affect me?"
"I see you have exposed yourself to many different mixtures haven't you?" The man smirked. Mayuri liked this guy. He was sure interesting. The man could create lots of interesting potions. Mayuri chuckled as he easily blocked another smoke bomb of a new potion. Mayuri pulled out his own potion and threw it at the man.
He caught it calmly and held it up to his face. "This is some good work, I'm impressed…. Tell me…. What is your name?"
"I am Mayuri Kurotsuchi. You are?"
"Teko. That is all you have to call me."
Mayuri smirked. "It will be nice to know the name of a worthy opponent that I killed."
Teko began to laugh. "You truly think you can kill me? He smirked. "I have immunity to every poison ever created… I've even created my own potions in the world."
Mayuri smirked. "As do I…."
Teko and Mayuri stared each other down and then began to throw different homemade potions at each other. Both easily brushed off the other's potion.
Mayuri frowned as another potion of his failed. He didn't need to… he wanted to kill the man now. A burning sensation suddenly sparked along his arm. Mayuri glanced down to see a large welt forming on his arm.
Teko started to laugh. "My own little potion. Nothing like it has ever been seen before. By this time tomorrow you will be dead… In an hour your arm will be swelled up to the size of a watermelon and then it will burst. But that won't kill you. It will just be extremely painful. And there is no cure."
"Really? Not even you have your own cure?" Mayuri smirked.
"Sometimes that is the best way to insure there is no cure."
Mayuri laughed and gripped his arm above where the splatter was. "I guess we will have to see what is going to happen, have you ever used it before?"
"No." Teko smirked. "So I too am interested in what is going to happen as it progresses."
"Oh yes." Mayuri laughed. "This will be an interesting match, won't it?"
