Character development is an integral part ofthe growth of most shonen anime protagonists, but in some cases, this takes a back seat to the battles they participate in and the power ups they unlock. In this sense, character development does not refer to a protagonist’s strength, abilities, or fighting style, which obviously see massive development throughout a series, but to their emotional growth and maturity. Hence, some of the most well known protagonists in shonen anime do have a tendency to stay the same at their very core, even if their prowess in combat increases to a great extent.

Some names may immediately come to mind, and there is often great debate around what constitutes development for most. Additionally, the fact that some protagonists do not have great development is not a criticism aimed at their character or at the series as a whole. On some occasions, this canshift the focus from the protagonistto supporting characters, for better or for worse. Alternatively, this approach can even be used explore the way the protagonist actually impacts the world around them rather than having them undergo massive changes in their behavior over the course of several narrative arcs.
