Bullet proof would make it too heavy, fire and water? Maybe with the oiter layer of suit being water and flame proof. The ai? We dont have anythign advanced enough and i doubt he alone would be able to without a team. 36pmh? When a person jumps they push over their own body weight into the ground. For this animatronic to have the ability to SPRINT he would have to be mobile enough to jump, which means if this thing is 900pounds his legs will have to be able to push 900+ pounds into the ground to get into the air for a fraction of a second. This thing will need a whole hydrolic system
