Even if you remove her "Spirit of Truth" aspect (which would be silly, like removing Batman's detective aspect--oh wait--or Superman's friend to everyone aspect--oh wait),
It has to do with the setting changes. Short version: The Wonder Woman Mythology as filtered through the Stargate. There's more to it (About a hundred years of history beyond that) but that's the short version.
I'd like to think I hit the nonjudgemental and sureness without arrogance aspects, as well as the compassion/understanding. The other issues have yet to come up. But I'll probably touch on them soon.
