Yeah, Batman has built robot suits (and also built the Beyond one). But has he built the IRON MAN suit, is what I'm saying. Instead of building numerous single-application disposable tinfoil suits, just build the one you will wear for the rest of your life and consistently kick ass in. Batman's best suit, by far, was the Beyond getup and even then, it didn't measure up to an iota of the Iron Man's capabilities. It still required Terry to do much of the work.
I don't disagree that the suit is iconic, though.
