Yuusei Shonen

Yuusei Shonen no Kyohaku Sekkou (Planet Boy of the Space Patrol) is an open source character created by Simon Kirby and released via MSN Group in 2005. Loosely based on early 60s Japanese cartoons (Astroboy, Gigantor, Prince Planet, etc), Yuusei Shonen follows the story of a young extra-terrestrial warrior defending the Earth from alien menaces.

Synopsis
A vast shadow has fallen over the planet Earth in the "far-off future" of 2010. The shape-shifting Zykons, one of the most hated species in entire the galaxy, have begun infiltrating human society via its smallest and most defenseless members: young children.

While this secret invasion goes unnoticed by most of humanity, The Supreme Galactic Council has sent its greatest warrior to deal with the Zykon infestation. Armed with the power and technology of a thousand worlds, Yuusei Shonen undertakes the most important mission of his career - to protect an entire planet from the most dangerous creatures in the universe.

His orders are simple: hunt down and exterminate the Zykons before they can breed. Failure is not an option; if the aliens manage to propagate, The Galactic Council will be forced to destroy the entire solar system.

The fate of the Earth is literally in Yuusei's hands - but how can he even hope to succeed against such a devious and dangerous enemy?

Powers and Abilities
Yuusei's greatest asset is his superhuman intelligence: like most of his species, he can learn entire languages in a matter of moments and perform complex calculations faster than the most advanced computers. In addition, he is roughly six times as powerful as the average human being in his "powered down" state; the result of his race evolving on a massive G-type planet (Galacta). This innate strength is enhanced through various force fields generated by his bio-suit, granting him near-invulnerability, resistance to most forms of radiation, and the ability to survive in space for extended periods. Within the Earth's atmosphere, he has been known to fly in excess of mach 6, sheering through reinforced steel to send ICBMs plummeting from the skies. When extending his powers to the limit, he is easily a match for high-level superhumans such as Excelsior or Selina, though he can only maintain this state for around two hours due to the drain on his energy reserves. Consequently, Yuusei tends to rely more on strategy than brute force to accomplish his ends.
