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 cinta to spend time with. Something that could also be berkata for the general Image of Santa Claus. And yeah, his stature certainly bears a resemblance too XD Especially in The Legend of Korra !!!!
