Zero

ZJ00 or Zero is one of the four main characters on Mega Man X. He is the oldest and the most intelligent robot of the team. He is also considered to be a scientist; although, some of his motives and means of doing scientific research are a bit tacky at times.

History
Zero was built by the ZedEx Robot Company on May 30th, 2996 in Tokyo, Japan. Zero was made for World War III and was designed to be impervious to any physical damage.

At some point in the war, Zero was stationed in vietnam where he experienced a series of mishaps. For example, he was forced to wear a crab costume, earing him the nicknames, "Mr. Krabs" or "Crazy Joe". Zero would return a year later to his regular missions, where he would be under the command of General Cracked-Head, a robot who was an aquavore and was known to brake down, frequently.

After the war ended, ZedEx filed for bankruptcy and scrapped many of their unfinished prototypes in a New York City landfill, steamrolled them, then poured cement over top of them and shot down any other in-development robots.

Now Zero has retired from the war and spends his days, inventing new types of gadgets, fighting crime and living a life in the city.

Appearance
Zero is a caucasian male robot, with long blonde hair, tied into a ponytail and blue eyes. He wears a pair of grey and black skin tight body suit underneath a set of red and white armor with a pair of green head lights and a small yellow fan on his chest, a red and white helmet with a blue head light on top, white gloves and a pair of red boots.

Personality
Zero is the most intelligent and logical of the group. He's often the one to point out the suspicion that grows into chaos. His high intellect and experience had made him the rational voice on the team. In addition, Zero has the most authority over his roommates/team members and has lead them for inspiration.

Despite being a mild mannered and sensible bot, Zero does have his fair share of behavior issues. For Example, he has his patients tested by people around him, at first he starts off with keeping his cool but then quickly, looses his temper when ever the problem escelates into something serious.
