Hero + Villan =

The sun was just rising in New york as Ace arrived, not a cloud in the sky. Ace shook to get rid of any random static, Ace grinned "Good now it's time to make a name for myself in this city".
Ace picked the city because it was always seen in movies, he'd actually never seen a super hero movie that wasn't set in New york, it also had the most amount of attacks per year on average.

As 7 o'clock approached he was ready, he had his costume on under his clothes and his phone at the ready for a quick escape. He thought "maybe there will be a couple of robbers no biggie" He didn't know how wrong he was.
(Sorry if it's too short I rushed it a bit)

Sin hummed quietly to himself as he retracted his bones back into his skin and wiped some of the blood off of his arms. The bank was more like a morgue now, a small pile of corpses stacked in the middle of the room, a single, huge bone piercing them through the middle. Sin hopped over the counter and walked around to the back of the bank where they kept the money. The security guards had been no problem, but he had set an alarm off which meant police were sure to arrive on the scene within minutes. He had to be quick.
Sin set about starting to prepare for busting the vault when he heard it, a high-pitched crackling sound was audible in the distance. Probably just a loose circuit or something he told himself and went back to work on breaking the vault open.

Ace was wandering past a bakers when he heard a alarm, as masked as it was I was an alarm. He ran towards the noise, as he got closer the source he saw people dead and mortally wounded "Oh crap " the thought to himself then he saw it, the alarm was attached to a bank where several people were dead huge cuts through their middle like cat claws except bigger. Ace was cursing in his head. He stripped to his costume and headed towards the vault door, he powered up "it's not good to leave open wires" Ace said as he shot a bolt into the back of the villain.

Sin hears the faint crackling noise get louder and closer, the buzzing was getting annoying and distracting him from his work cracking the vault open. "It's not good to leave open wires" says a voice from behind him and Sin whirls around and ducks as he sees the newcomer fire something at him from his hands, the vault behind Sin melting slightly on the impact. The figure was wearing some kind of outfit, obviously someone trying to be another hero.
Sin smirks, thinking that it's just some tryhard kid with some fancy gadgets. He shrugs his shoulders and pushes his shoulder, forearm and back bones through his skin and hardening them, forming a grotesque armour of sorts. Sin then pushes another set of bones outside of his arms, shaping them into a spear-like shape and preparing to fight. He throws one of the bones at the hero then springs towards him slashing with the other with his superhuman speed and strength.

Ace watched in horror as bones moved from places in his body and hardening in place, "his power is moving bones " Ace thought "hehehe moving bones" Ace's thought was interrupted by a man with blood stained bone claws dashing towards him with super speed. He reacted as quickly as he could electrifying the floor and jumping through just as the man lunged at him.

He found himself in a basement, it was dark, damp and smelled,well better than upstairs but still not good he looked to his left and saw he had been cut, a gash above his left arm, he gritted his teeth and electrified it, it stung for a bit but at least he could move it. He saw rats and water pipes "geez this is low tech for a bank, ok time to get out" thought Ace "wait water pipes, water can carry a current so I can get out, I just need to break that pipe" Ace charged at the pipe.
