One of the strongest characters to come out of Avatar: The Last Airbender was the General of the Fire Nation and former heir to the throne, Iroh. Serving as a kindhearted, funny, and wise mentor figure to Zuko, the Prince of the Fire Nation and his nephew, the character soon endeared himself to all the viewers.
There is no doubt that Iroh is one of the strongest characters in the world of Avatar: The Last Airbender, but the show has alluded to his power multiple times, even when he is not fighting in a combat situation. The character is very spiritually attuned, something that usually indicates how powerful a character is in the world of Avatar: The Last Airbender.
Iroh could be as strong as the Avatars themselves
General Iroh is a competent fighter in the world of Avatar: The Last Airbender, earning the monicker of the Dragon of the West for his exploits. The character is also shown to be very open-minded and spiritually attuned, which is demonstrated by his various spiritual feats, mostly accomplished only by Avatars, who serve as conduits between the spirit and the material worlds.
One such example is the fact that Iroh can see Avatar Aang’s spiritual form when he sees him fly over the Earth Kingdom with Roku’s Dragon. Spirits usually can be invisible to human begins, but the fact that Iroh could see their astral projections, puts him in the same ballpark as the Avatars. Iroh has always demonstrated that his philosophy draws from the four dominant cultures of the world of Avatar: The Last Airbender, which allows him to develop his own techniques and be a competent fighter with a calm and collected thought process, that is humble and kind.
Iroh was also one of the few characters we saw in the Spiritual Realm in Avatar: The Legend of Korra
Thanks to his strong spiritual energy, Iroh is able to appear in the Spirit Realm and impart wisdom to characters like Korra. Iroh is considered to be one of the wisest characters in the world of Avatar, drawing wisdom from all paths of life, and being a beacon of hope for Zuko. With how spiritually competent the character is, we are shown that the character manifests himself in the Spirit World, something that we have only seen Avatars do.
Iroh is widely considered to be one of the best characters in the world of Avatar, whose wisdom guides characters and audiences alike as they go through the challenges of life. The character has also been shown to be kind and understanding, despite his immense power. He is considered one of the best mentor figures in fiction and has been able to make quite an impression on the Avatar fandom.
