The Hunter is one of the worlds most proficient heroes, despite not actually having any super powers, like so many of his fellow heroes. He is simply a master martial artist (one of the best in the world) with great tracking skills.
Lee Shen Dai had dedicated his life to mastering the martial arts of the world. Growing up in the hidden city of Shambala Vale, he began by mastering one of the most powerful styles known to man. After coming of age, he set out into the wider world in order to learn many more. He eventually arrived in America where he encountered a number of masked heroes and, more worryingly, super powered criminals. Dai resolved to use his skills in the martial arts and his uncanny ability to track down just about anyone to help his new found hero friends and make the world a better place.
