Why a character chooses not to do something in any given situation is up to the writers. It has nothing to do with retcons. There are many instances in which we, the viewers, having a "bird's eye view" of the situation, as well as the benefit of hindsight (on occasion), can see how a different course of action would've been better than the one chosen by the characters. However, if you take them to be real people, the fact is, they didn't see things our way. Why didn't Ben use [insert transformation name here] to fight against [insert villain name here]? Maybe because he didn't think it was a good idea. Maybe he just didn't think of it. Maybe it would've taken time to scroll through the 60+ aliens to get to the right one, and he couldn't do it.
