Jian-Guo was always going to succeed in life. His favourite uncle convinced him to follow him into a career in aviation, and Jian-Guo proved himself a superb pilot, even gaining the attention of the military. Before he could be accepted into the airforce, however, Jian-Guo was involved in a horrendous crash when a military helicopter he was co-piloting was struck by a severe thunderstorm. The helicopter was carrying explosives and exploded when it was forced to crash land after its rotors were disabled in the storm. The helicopter erupted into flames, forcing the crew out of the front windscreen. Jian-Guo managed to shield his pilot and saved his life. It was discovered that Jian-Guo was an uber, so instead of joining the airforce, he was diverted into the uber programme.

While undergoing training and research into his uberphysiology, Jian-Guo met and fell in love with one of the experts in ubergenetics, Tai Jing-wei. He was the ideal subject, willing to serve his country without question, and undertake any kind of experiment of assignment.

When the Immortals were reorganised, Ox was assigned, and while he was initially tagged to take on a leadership role, he was overlooked in favour of the new Rat. Ox wasn't overly concerned, although there is a kind of rivalry between the two men, and celebrated his new assignment by proposing to Jing-wei.

Shang Jian-Guo is a competent man, able to handle himself equally well in a cockpit as well as on the front lines of a natural disaster. He has taken to his role as a Defender of China more easily than any other member of the Immortals, and upholds the ideals of his country and the public image of his name. He is devoted to his wife, but such devotion is pale in comparison to his devotion for his country.

“Gawkers to the side, Ox is coming through!”

Ox possesses uberhuman strength and durability, which is reinforced even further when he is running. He is capable of extreme running speeds, and while doing so is virtually unstoppable and impervious to the most excessive of physical damage.

Jian-Guo has always been powerfully built, and since he has reached adulthood his physical bulk has been shaped by his ubergene. He has very broad shoulders and powerful leg muscles. As Ox, he wears the Immortals costume, including head gear and shades which protect his identity, and most importantly his wife. Out of uniform, Jian-Guo has very short cropped hair and a pleasant smile which reflects his general confidence.
