Titan Legacy
In 2020, a mysterious energy appears on Earth. Earth's scientist do everything they can to identify it and it's uses, but they don't make any headway. Instead, it is a lone martial artist from China by the name of Li Jie who discovers the energy's true nature.
The energy turns out to be capable of strengthening the human body, making people into superhumans capable of things nobody thought possible.
Soon people from Earth begin making use of this energy, and dojo's that specialize in the teaching of the energy appear.
But it is quickly made apparent that all that is only the start of things to come, when a tremendous occurrence takes place one year later. Something big enough to shock everyone on Earth, and set the gears of change moving at a rapid speed.
This is the end, or perhaps just the beginning?
