Comparison between Manga and Movie
In the Manga, Dester's large body revealed to be a mini-mecha piloted by Desta himself. Also, when Desta escaped from the rocket, he had short fight with the gang only for subdued with Air Cannon, destroying his mecha and knock him out in process.
In the movie, he is just wearing an armor and weakened by Doraemon who accidently rammed him with his head earlier, and when he woke up and came out from the portal, he's still in the pain that he passed out again before the gang had the chance to subdued him.
