This rewrite in terms of plot development and development of secondary characters is better, but when we talk about the development of MC is much worse than the original story, in this rewrite lacks common sense and intelligence, he became a generic protagonist, when the charm that this MC had in the previous story was his prudence in using the Omnitrix to save others and did not use it as blatantly as in this version and most importantly showed a certain selfishness that made it more realistic.
One of the best hits of the previous version was how the MC created a technology company, in that world there are many geniuses so it would not be strange that the MC would pass for one of them and also with gray matter would be in the top of the most intelligent of the Marvel universe, perhaps only one or 2 would be above him as Reed Richards.
