[@Holy Soldier] I don't think you'd have to rewrite the whole bio, he creates stuff with his mind so it's not beyond the realm of possibility to control it with his mind too. Letting a construct human get shot and then making a construct helicopter go down because of it doesn't make much sense either when he could literally just imagine another human construct in the other's place. There's also the option of creating a vehicle construct for somebody else to pilot/drive. 

Creating objects is one thing, creating life... even as a construct, is a bit too God-like and it needs more limits somewhere. The Dog Tags being his only real weakness is also a problem and contradicts itself. When removed he is powered down to a normal human, but without them he'll fall victim to his own imagination? Which is it? He either has powers when they're on or off, but still... that being his only weakness is a problem. And HE created them? He was trained by the government but now he's a scientist/inventor as well?

Upon closer inspection those bits need more work, but still I like the general idea of this guy.
