The concept of the "composite hero" is a way to think about how narratives like this:
Can be compared to narratives like this:
Rosen, probably drawing on the work of famed Ramayana scholar Robert Goldman, notes that in the Indian epic the characters of Rama, his brother Lakshmana, his wife Sita, and his follower Hanuman (pictured above), all complement and complete one another. (For a quick synopsis of the Ramayana, read this link or, better yet, get this book!) Rama is the paradigmatic leader and king, Lakshmana represents brotherly loyalty, Hanuman stands for strength and devotion, and Sita is the exemplar of faithful womanhood. (Sita's portrayal has been seen as problematic and its cultural meaning is, at the least, debatable.)
The novel Watership Down, which is one of my absolute favorites to have read with Xander, has much the same dynamic.
The book tells the story of a group of rabbits fleeing a disaster and trying to establish a new warren. For those who haven't read it, the book is remarkably erudite and is in many ways a version of the Aeneid, but for kids...and with rabbits. Hazel is a caring, natural leader, Bigwig is tough and resolute, Bluebell provides humor, Dandelion tells stories for the group, Fiver is a kind of prophet and seer, and so on. None of these rabbits would be able to make it as an individual, but by pooling their talents, they are able to survive and create a new home.
A currently popular mythic narrative speaks to the same sense of composite heroics.
