Ben 10 Sequence
Ben 10 has one of the most numbers of aliens that he can transformed into. For sure, there are other heroes that can transformed into different being more than 10, but Ben is the only guy that transform into 10 different alien beings. He is not the strongest, the fastest, or the smartest in the world, but his transformation makes it up for all those since it helps him defeat the evil aliens that are out to do some harm on mankind. He likes smoothies that might not help him in battle, but that what keeps him happy most of the time and no one has the right to take that away from him. As we all know by now, he likes to randomly transform into different alien to fight his enemies. And transforming randomly is something that he can take care off as he gets older. In time, Asmutt will give him a better device that can do such and will make him much more powerful than he is now. But, that will take a long time and Ben is contented right now with his transformation.
