Simon is a well know hero in the great city of New York. Everyone knew him for his courage and strength, he always managed to save the most needy with his powers...

Loved and respected by adults and children, Simon had quickly become the most popular superhero in the city... but there was one person he hated like crazy: Axel Kitasuka

Axel was a villain, a dangerous and ruthless man, despised even by some heroes in the city. He had regenerative powers, was difficult to capture and always had an advantage in escape.

Also…Axel and Simon were childhood friends, but they both went their separate ways, separating for years.

Currently, Simon was fighting a villain, managing to capture him and send him to prison, but before the villain fainted, the villain held a syringe on Simon's wrist...

Simon had been feeling bad for days after that accident, he had pain everywhere and not even his powers had been able to make him feel better...so...why not try asking for help?

Late at night, wandering through the labyrinths of dark alleys of the city, in the part little monitored by justice, Simon knocked on an old door... Axel's base was not secret, but well hidden. Axel told Simon the coordinates of his base when they were still children, that's why Simon knew where he lived...

Simon knew it was a bad idea...but no one would have helped him except...well, him. Axel was, apart from a dangerous villain, also an expert scientist...
