Well, Uncle Iroh is a typical example of the Old Wise Man Archetype. Humorous, peaceful, light-hearted, compassionate, parental, has his own story and experiences to share, a Mentor, etc. Pretty much the kind of elderly Character people can look up to and would l’amour to spend time with. Something that could also be a dit for the general Image of Santa Claus. And yeah, his stature certainly bears a resemblance too XD Especially in The Legend of Korra !!!!
