"Yeah, I can fly, shoot lasers and lift buses, but do you know what my real power is? Looks"
Zachary can be described as.... Tony Stark's son. He is smart, funny and sarcastic to say the least. However, he also holds with him a great sense of heroism, and can not force himself to stand by while people get hurt or killed. For that reason, Stark took him up as an apprentice and showed him the ropes. Although Zach isn't stupid, he isn't a genius either.
Stark gave him all the information he needed to know to use his suit, and with that, Mech was born. Zach dispises his greedy father and has cut ties with the man who forced him and his mother to the streets. Since Zach learned and studied Tae-Kwon-Do, he became an instructor to earn money for them. So, he is actually a good fighter, but does not prefer to be in them regardless.
Zach keeps with him at all times:
His MP3, Cell Phone and watch. He isn't one to forget these few items, and when bored will use them to entertain himself.
Zach was born as the heir to the Atlas corp, a rising weapons manufacturer. His father, Jeffrey Conway, was greedy and overall a bad person, and attempted to steal the Iron Man blueprints. However, he was caught and sued rightfully, causing the family to lose EVERYTHING they had except for a house. This bred a deep resentment for Zach's father, rather than Tony Stark. Afterwards, they never really spoke again.
His mother sick, Zach was forced to take up a job in order to support them after she divorced, and thought it best to instruct kids at a Tae-Kwon-Do dojo. As such, he has a smaller pay, but he does know how to fight very good. That being said, he doesn't go on the lookout for fights.
One day, Tony Stark himself offered Zach something he couldn't resist, and Zach, having no hard feelings because of the circumstances, accepted gleefully.
(If needed, I will elaborate on bio.... Also, again: Don't reject, tell me what's wrong and I'll fix it. IT TAKES FOREVER to do this.... :D)
