An Absorbascommenter wrote me a private email about the idea of applying our "Dynastic Centerpiece Model" to teams instead of individuals. Let's!
For those who've just joined us, the Dynastic Centerpiece (DC) model is the loose application of a set of character archtypes to building a mythos around a central figure, a "dynastic centerpiece". Here's an example: Centerpiece (Batman), Junior Version (Nightwing), Sidekick (Robin), Black Sheep (Huntress), Elder Statesman (NONE), Animal Companion (Bathound), Female Version (Batgirl), Authority Figure (Commissioner Gordon), Civilian Companion (Alfred), etc. This model applies to many of DC's iconic characters to varying degrees.
To some degree, I guess, it applies to supergroups as well. Centerpiece (JLA), Junior Version (Outsiders), Sidekick (Teen Titans), Black Sheep (JLElite), Elder Statesman (JSA), Animal Companion (I'm not sure the Legion of SuperPets counts!), Female Version (expand the Birds of Prey a bit...), Authority Figure (DEO), Civilian Companion (nothing there).
