Name: Coal (obviously :( )
Weapon of choice: Twin Nunchaku
Back story: As a young boy, Coal was fascinated with the Nunchaku, a weapon that originated in his birthplace and hometown; Tokyo. He always wanted to know how to use it and, even more so, how to become the best fighter in his country. All this came true, but not in a way you would expect...
At the age of 18, he was already a veteran martial artist and he was a VERY experienced one as well. Just one kick from could break your bones and two punches would make you realise that you don't have a chance. One year later, he decided to travel round the world for one reason, "The fighters here are far too weak. I want to search for a worthy opponent that doesn't get hurt too much by my techniques."
And he did, however, his journey came to a sudden halt when he entered a strange cavern. In it was a shrine, he touched it. Suddenly, the ground shook and Coal shook with it. This had never happened before. Then, he saw a strange, white light. He took one step forward, only to have a gigantic stalactite fall onto his leg, breaking it. Coal yelled in agonising pain. "It can't be..." His mind spoke, "Is this the end of my life?! I'm far too young to die now!.......SHIT!!!!"
It caved in. Hours passed until he, somehow, woke up. It was a blank room he stood in. A dark-blue hand reached out to him; it was Yoyo. "Welcome" he said.
"Who are you? And where are we?"
"I'm Yoyo and this is Stickpage. You're a new RHG AKA Rock Hard Gladiator. RHGs challenge other RHGs to a duel. There is gore, but every RHG is immortal."
"Y-you mean no one dies here?"
"They do, but they get revived after that. By the way, I have something for you, Coal."
"Nunchucks?"
"Yes."
"Show me my first opponent."
"Ah, you'll have to wait for that"
So yes, Coal is basically a martial artist that got his 2 wishes and a second chance in life.
