The past part 1

Sincere knocked on Casey's window and climbed in, his body filled with bruises for the first time ever. "Sin!" Casey. exclaimed and helped him on the bed. "I'm alright." Sin groaned rubbed his wounds. "What happened?!" Casey asked demanding an answer as he treated the wounds with a first aid kit. "A new vigilante, he's incredible strong, I held back because he reminded me of someone, but I don't know why." Sin explained and sat up. "If he was that strong to leave a bruise on the perfect body, are you sure you can beat him?" Casey asked and finished wrapping Sin up. "If you're asking if I'd lose to a new vigilante, nah, I'd win." He said with a smirk.

The next morning

Sin stood on a building with his costume on. "Where are you?" He muttered to himself and as soon as he turned to his side he was greeted with a punch to his face which sent him flying into a vent on the building. "You are so stubborn you know that!" TNT yelled and ran towards Sin to send a kick. "Take your attack back!" Sin punched his kick and sent him back. "Who are you man! Heroes aren't supposed to fight heroes!"

Tnt threw punches at Sin and Sin did jumped on his head with one foot and kicked him down. "Who do you think you?" Sin said with a laugh.

As TNT struggled to get back up, Sin approached him with a confident smirk. "You may be strong, but I've faced tougher opponents than you, I beat Killer Croc on my first try."

As the battle raged on, Sin couldn't help but feel a sense of familiarity. There was something about TNT's fighting style, but he couldn't quite put his finger on it. The thought only fueled his determination to defeat TNT and uncover the truth.

TNT then pulled out a knife and attacked Sin who immediately countered with his vampire sais. "Finally some action." Sin smiled and the two began attacking each other. Their movements were a blur, a deadly dance of blades and fists. Sin's vampire sais clashed against TNT's knife, each strike accompanied by a shower of sparks. The air crackled with intensity as the two heroes fought, their determination driving them to push their limits.

Sin's agility and speed allowed him to dodge TNT's knife strikes with ease, while his precise strikes with the sais kept TNT on the defensive. But TNT was relentless, his attacks fueled by a burning desire to prove himself.

Sin threw a tornado kick at TNT which broke and cracked his tnt helmet. TNT covered his face then eventually revealed himself as…
