Hypersonic

Brief Overview
Hypersonic (William Puerto) is one of Crimson's villains and is only known around because when he first got his powers, he was mistaken for the hero on his first ever run through the island. He then went on to be a menace to the people of the Isle of Oasis as he could easily penetrate security and take things without actually being seen. He also decided to take it upon himself to 'justify' the wrong done in the world by murdering many people who have been known to rape, murder, abuse and go against the justice system. This is why he goes after the members of the league as truthfully, they are not exactly abiding by laws.

Backstory
Puerto was actually a decorated officer of the police force and had many years behind him as an officer and a detective. This is why his personal mission later turned into an overly 'unfair' massacre on the wrong-doers of the law. In his eyes he is actually just acting how he would on a case: solve the case, find the culprit and solve the problem.

Early Life
His early life is not one of happiness as he was put into care homes after his parents randomly vanished, he did not know any other family members and he did not have any siblings so his life was one of torment as, well he is adopted (and people think that's hilarious) and one of isolation as he never really trusted anyone.

How His Powers Were Achieved
Hypersonic gained his powers in quite an unusual way. He got his powers during the War of The Gods, as at the exact time of the 'Final Punch' occurred, he was on his own cave exploration and had found a crack in space-time. When the punch took place, it spilt a form of radiation (unknown by any records whatsoever) and contaminated William, thus his powers came to light. His powers however, were only discovered after the war as he was hospitalised by a falling rock in the cave because of the shock-wave created by Blazerunner and Crimson during the event.

Crimson's Targeting
Puerto went mostly after the hero Crimson as he has the more-known criminal record because of his early days and also because he once tried to help him solve a case but accidentally got Will kicked off the case and solved it solo meaning Crimson got all of the credit without a praise going to Puerto.
