Rocketfist the Echidna

Rocketfist is an Echidna born on Planet Namek. He doesn't enjoy anything and hates everyone. Rocketfist is known as one of the greatest fighters in the universe and is a power/speed type. Several years ago, he lost his right hand in a fight with Jesus. His missing hand was replaced by a giganto-fist that shoots off like a rocket. His age is unknown even to him. He dyed some of the quills purple and wears a black coat with black shoes and shades. The reason for him being green is he got some radiation poisoning in a fight with a radioactive sludge monster-man. 
Dan the Echidna, AKA "Rocketfist," is an echidna training to be the strongest being in the universe. He is the enemy of sharks worldwide, as he uses them as sparring partners, whether or not they agree to participate. His name comes from his ability to project fist-shaped energy blasts by punching, and more recently, from his ability to fire off his giant fist like a rocket.
History
Not much is known of Rocketfist's past, due to his amnesia and general obscurity. His furthest back memories include his time on planet Namek, where he first began his training to become the strongest fighter in the universe. During this time, he was still just an ordinary red echidna who could not shoot fist blasts, and went by the name of Dan. He spent his days training and seeking out opponents to test his skills, until one day he came across Mo'Dok, the radioactive sludge monster-man. The two became engaged in a fierce battle, and the outcome was not clear. However, after several hours of intense combat, Dan managed to gain the upper hand, and victory was almost within his reach. Mo'Dok could sense this, and being a vengeful sludge monster-man, decided to attempt to take Dan down with him. He used the last of his strength to self-destruct, dousing Dan with radioactivity and turning him green as a result. In addition to his newfound color scheme, Dan also found that he was now much stronger than before, and could now fire energy from his fists with proper focus. Dan, now going under the name "Rocketfist" due to his newfound abilities, sets off to new places to further test his abilities.
Rocketfist soon arrives at Earth, crashing into the Pacific Ocean. It is there that he has his first encounter with a shark. Rocketfists fights off the sharks, but due to the encounter, percieves sharks to be the strongest beings on the planet, and vows to defeat them all in order to further his training. He gets a job as a Coast Guard in order to complete this mission. One day, he is attacked by a rogue shark who gains an early advantage in their fight by catching him off guard. Rocketfist makes a valiant effort to overcome the shark, but in the end, he cannot regain the ground he has lost and is defeated, losing one of his hands in the process. He falls unconscious, and slips into the ocean.
After losing to the shark, Rocketfist wakes to find himself in one of Dr. Eggman's labs with a giant robo-fist to replace the one he had lost. The trauma caused by the event also changed his mind - his defeat has made him bitter. He breaks out of the lab, and sets out to exact his revenge on the shark who took his hand from him.
Personality
While he was still known as Dan, Rocketfist was very dedicated to and focused on his training, leaving little time for anything else. Before he became Rocketfist, he was at least vaguely sociable and would enjoy what spare time he had with the few friends he had made.
After becoming Rockefist, he became even more devoted to becoming stronger, and this desire only intensified after having one of his fists replaced with a giant robo-fist. He completely shut himself off from others, only caring about himself and his desires.
Rocketfist's one defining characteristic is his pride in and devotion to his strength. He named his left and right fists "The Tighty Righty" and "The Defty Lefty," respectively. He continued to use these names even after he recieved his powers from Mo'Dok, but stopped once he lost his right hand to the shark. He frequently cites "The Defty Lefty" as one of his main motivations for getting revenge.
Abilities'''
Due to the incredible amount of training he has undergone, Rocketfist is incredibly strong, even being able to hold his own against Knuckles. He knows a variety of techniques to aid him in battle, including many ranged techniques. He can fire fist-shaped energy blasts from his left hand, and can fire off his right hand like a rocket. He also has many abilities similar to those of Knuckles, including the ability to glide and climb walls.
Appearances in Games
Rocketfist has appeared in several fan games, as a protagonist, as an enemy, and as a cameo appearance.
Rocketfist
His premier appearance, simply titled "Rocketfist," is a re-telling of the fight in which Rocketfist lost his fist. Rocketfist is capable of defeating the shark in this game, resulting in his fist not being lost. His abilities in this game reflect the basic abilities he possessed before his fist was replaced. He can perform a simple one-two punch combo, a dash punch, an uppercut, and a dive punch. The game lacks any significant plot, and consists of a sole boss fight.
Knuckles of Fury II: There's Bingo on the Table
Eggman has obtained several of the Chaos Emeralds, and using their power, builds a device that creates several clones of Knuckles. The clones each guard an emerald, and are sent to retrieve the last remaining few emeralds that Eggman does not yet have. Rocketfist makes a cameo in this as-of-yet unreleased game, fighting against Knuckles and his clones to obtain the chaos emeralds, figuring that he might as well use them to increase his own strength if their locations are known. Rocketfist's playstyle revolves around keeping the opponent at a distance by utilizing his ranged moves.
Weaknesses
Rocketfist's fighting style lacks any glaring flaws, though he is a bit reliant on ranged attacks. He has s bit of trouble fighting at close range, which is why many of his moves move him away from or around his opponent.
Rocketfist also has a slight addiction to chocolate.
Super Forms
Currently, Rocketfist only has one super form, known as Super Rocketfist. In this form, he glows a bright green and gains the ability to fly. His ability to shoot energy blasts is also greatly amplified, though they take the form of bright green orbs instead of fists. His fist-shot technique is also improved, moving at a much quicker speed.
His super form, unlike the super forms of characters such as Sonic and Knuckles, is not activated through the use of emeralds. When he first awoke after losing his fist, his utter disdain at the fact that he had lost his favorite fist was so great that it unleashed hidden powers deep within him. Using these powers, he sought out the shark that had defeated him before. Other than this, he has yet to activate his super form again.
