>>98034148Did it say he'd never be able to change, or just that he'd have difficulty using his other forms? Its been a while since I've seen it. I just remember that it was supposed to be bad for you to do it, and that was part of the reason why the Omnitrix had such a short timer. The other part, of course, being how much energy the transformations required to sustain.
I also got the feeling with Bullfrag that there is a special set of circumstances that allowed him to be another species for an extended period of time that wouldn't apply if Ben was just using one form over and over again. Azmuth called it something special, like FormLock or LifeLock or something to that effect, and it required a special code to enable.
As for feedback, it was kind of weird. The implication was that Ben was literally getting addicted to being him. I'm not sure if its because the way he was using feebacks powers was addictive or if the feeling of simply being in that form was more enjoyable. It never really got too in detail.
It was an interesting concept, and I liked the story arc, don't get me wrong, but then after all this build up we never really saw much of him again. Maybe two or three times, plus him being the last Alien Form to hold in the power of the Big Bang in the finale.
