Origin Revealed History
Neptune Perkins is a human/dolphin hybrid, and received his powers from his conception before a magical energy source known as the Vril.
The Vril was brought to Earth by an alien race known as the Dyzan, and was discovered in the 1800s by Neptune's grandfather, Arthur Gordon Pym. Pym used the the power of the Vril to control the remaining Dyzan and pillage ships on the high seas.
Neptune's father, Ross, was the result of a short-lived marriage between Pym, who had taken the surname Perkins, and a wealthy woman that did not survive childbirth. Ross Perkins was raised by Pym until the age of ten, when he was sent back to the United States.
In 1912 Pym sank the Titanic and took some of the ship's survivors and the wealth on board. One of those survivors would later become the mother of Neptune Perkins after marrying Ross.
The couple hoped that by conceiving a child in the presence of the Vril, the child would grow to be a powerful force for good, and someday exact their vengeance on Pym.
Upon his birth, Neptune's parents were told that their young son was a mutant with a sodium salt deficiency and webbed hands and feet. Neptune's sodium salt deficiency required him to remain in a salt bath to survive. Neptune spent most of his early life in the saltwater of the ocean, and became an excellent undersea diver and swimmer.
Nazis murdered Neptune's parents in hopes of following him to his grandfather, but he was still unaware of the location, or even the existence, of Pym. Neptune lived a life of almost complete isolation from humans, and wrote a book about sea life.
At the outset of American involvement in World War Two, Neptune and Johnny Quick were captured by a Japanese submarine off the coast of Santa Barbara, California. The submarine was there to destroy nearby oil fields, and had eliminated a United States Coast Guard cutter in the process. Firebrand, Liberty Belle and Starman rescued the captured heroes.
The humans on board were killed in an explosion of the submarine in the battle. Miya Shimada, known by the name Tsunami, survived the blast and fought Neptune. She managed to overpower him and escaped the fight with her life. Neptune would later fall in love with Tsunami when they teamed up to aid the All-Star Squadron in the fight against Axis Amerika.
Neptune fought alongside his grandfather and the Young All-Stars when Adolf Hitler attempted to take control of the Vril and the Dyzan. Pym died in the assault and the Dyzan returned home.
After the War Years ...
Neptune became a successful author after the war, when his studies of marine life were published. His love for Tsunami was returned and she bore a child named Debbie. Neptune believed Debbie to be his daughter, but a sorcerer from Atlantis named Altan was her true biological father. After the end of his relationship with Miya, Neptune decided to move to a home on land.
Years later, all the nations of the seas were called together by Aquaman to take on Rhombus. Neptune, Miya and Debbie, now known as Deep Blue, all answered the call. Rhombus claimed to be Debbie's father, but Miya did not clarify the child's true origin.
Neptune would later become a successful politician, winning election as a United States Senator from Hawaii. He used this position to build a committee to oversee the activities of Young Justice. Neptune and Dan Dunbar formed a team of former sidekicks and called themselves "Old Justice".
While defending the city of Sub Diego (a portion of San Diego that had been claimed by the sea) from the Secret Society of Super-Villains, Neptune was killed by the villains Shark and King Shark. At his death in the February 2006 issue of Infinite Crisis, Neptune still believed Debbie to be his daughter.
Skills and Abilities
Neptune's mutation allows him to communicate with sea life, mostly dolphins, and hold his breath for up to seven minutes. He also possesses webbed hands and feet, which allows him to swim with speed and endurance far beyond that of even the greatest human swimmers.
