Anime heroes are diverse individuals who come in all shapes and sizes. In the end, they are all heroes, whether they are mild-mannered and friendly or violent and unpredictable. Heroes, especially if they tend toward the more violent end of the spectrum, still put the welfare of others above their own.
Although the more aggressive and authoritative anime heroes may not demonstrate 'nice' attributes and can occasionally be unpleasant and foul-mouthed, more often than not, they stand up for what is right. Most of them share a concern for their loved ones and a willingness to do whatever it takes to ensure their safety.
