Multiverse: Federation

On Earth-24245, superhumans are called "chojin", because Japan is where they first began to appear. For a time, there was anarchy as people, emboldened by new powers, began to act out every suppressed urge and act, even as their own acts and powers began to warp their bodies into strange, even MONSTROUS forms. Luckily, other superbeings rose to the challenge to stop these new criminals. Thus was formed the Federation, an international group of chojin who fight to protect the world and humanity. Years have passed since the initial founding, and now a new generation of heroes has risen.

Hydrozoa: Hailing from the frigid climbs of Russia, Hydrozoa is a chojin with supreme mastery of hydrokinesis, the power to control and manipulate water in all its forms. His body has transformed into a being of living water held in humanoid form by a semi-permeable membrane, not unlike a jellyfish. Hydrozoa's control over every cell of his body is such he has been seen materializing pieces of his own human skeleton, such as his ribs or spine, and making them emerge from his skin to capture enemies and hold them while he delivers blows.

Checkmate: A homeless child from Monaco, the boy who would become Checkmate was among a group of orphans taken in by veteran hero Sunshine to train as potential successors. Sunshine was a strict and disciplined taskmaster, driving his students to train until the breaking point so they could grow stronger, but it worked. Checkmate grew into Sunshine's prized pupil and came to the Federation with his head held high. Checkmate's powers are... unusual to say the least, giving him the power of the three chess pieces represented in his armor. His most frequently seen, or BASE mode, is King, which grants him amazing intelligence and tactical cunning. When activating his Knight power, he transforms into a black-armored centaur with super speed, and his Rook power turns his body to stone, making him incredibly strong and nearly invulnerable.

Tusker: A powerful young Chojin from Ireland, Tusker is from an old family of fishermen, so it made sense when his powers manifested, his body transformed to take on traits from a powerful sea animal, in his case, a walrus. As a teenager, Tusker's father died in a storm, leaving him to look after his mother and little sister, Dorothy. Tusker entered the Federation's training program in the hopes of becoming a top hero so he could make money to send home to his family. Possessing immense strength and durability aside from his amphibious nature, Tusker is normally a friendly and easygoing young man, but get him angry and he will revert into a primal mind-set attacking his enemies like a savage animal with his claws and tusks until either he or his opponent falls.

Terry the Kid: A proud son of Texas, this young embodiment of the American dream is the son of veteran hero Terry "The Grand" Kenyon. Inspired by his father, a normal human who fought alongside heroes with such amazing skills and powers, Terry decided to follow in his father's footsteps and join the Federation himself one day. He threw himself into his training, honing his body to the very pinnacle of human perfection before travelling with his father to Federation headquarters to be presented. Though, like his father, he has no real superhuman powers, Terry has frequently faced down monsters and criminals several times his size and strength and come through, proving himself every bit the hero his father was.

Kid Muscle: Mantaro Kinnikuman is the son of legendary hero King Muscle, an alien Chojin from the Planet Kinniku, a large, mountainous world with gravity roughly 30 times that of Earth, which causes its natives to develop musculature far greater than a human. King Muscle was a founding member of the Federation and spent many years leading the fight against evil before marrying and taking his rightful place on Kinniku's throne. Born later in his parents' lives, Mantaro was something of a disappointment to his family dynasty, as he preferred scholarly pursuits to training and fighting in his people's traditions, even going so far as to call his father a musclebound brute who resorted to violence over diplomacy. Everything changed for Mantaro when a group of villains attacked Kinniku's capital city and he saw his father don his uniform to fight alongside the royal guard and protect their people. Sadly, King Muscle's age got the best of him after the battle and he was rendered bedridden to recover from the strain. Seeing his father's virtue and courage for the first time, Mantaro took his father's mask and uniform and travelled to Earth to carry on his family legacy.

Kevin Mask: Born and raised in London, England, Kevin is the son of legendary Chojin hero Robin Mask. Kevin's upbringing was strict, as Robin expected him to take his place in the Federation one day. Kevin was never allowed to play with other children in his neighborhood or go to a normal school. Instead, his every waking moment was spent training and being drilled in his father's fighting style. The boy was even punished severely for simply removing the heavy armored helmet Robin made him wear all day every day. Finally, Kevin couldn't take it anymore. He beat Robin within an inch of his life, destroyed his father's armor and trophies and ran away from home. Kevin would not be seen for almost ten years, having moved to Wales and made a life for himself, including having fallen and love and marrying a small-town girl and finding a job at a local supermarket. One day, returning home, Kevin discovered a group of street toughs trying to break into his home and chased them off. Comforting his wife, Kevin swore to drive the criminals out of their neighborhood forever and dug out his long-hidden mask and armor once again. The young knight had finally found a quest of his own.

Gazelleman: A talented young Chojin from Tanzania, Gazelleman is the prized student of founding Federation hero Buffalomon. Seeing the boy possessed amazing speed and agility, but lacking much in the way of strength or endurance, Buffaloman took the boy under his wing and trained him in how to use his own powers to counter those like Buffaloman himself, who specialize in strength and power-based moves.

Jaegar: Burn in Munich, Germany, the boy who would become Jaegar never knew his real parents. Most of his childhood was spent being raised by a kindly couple he refers to his aunt and uncle... until they were murdered by a gang of anti-Chojin thugs while he was out getting groceries for them. His guardians' last request was that he grow up to be a good and honorable man. Orphaned once more, Jaegar sought out the strongest Chojin in Germany, former Federation member, Broken Jr.  When he found him, Brocken was living as a drunk and was uninterested in doing anything to help himself, much less someone else, but when Jade showed off how strong he already was without any training, Brocken changed his mind and sobered up. Jaegar's training during this period was intense, involving karate chopping a scalding hot cauldron, doing reverse push ups with Brocken on his back, and running through the rain with a cathedral bell tied to his waist by a rope. As a man, Jaegar has perfected adapting Brocken's techniques into his own fighting style, including his master's famous "Red Rain of Berlin", a karate chop delivered with such strength and speed it can cause wounds on an enemy that spray blood like a fountain.
