I love the idea of Aizen being nerd and being fascinated by the evolution of life on earth. He would love paleontology, I think.
Hi! This actually made me thing of a little historical AU. Picture this:
It's year 1860. Charles Darwin just published his groundbreaking evolutionary research.
A young, brilliant biology student and naturalist set sails to a small island across the ocean to start his own research on an endemic species. His name is Sosuke Aizen.
And you can add his rival scientist Urahara, or another character just for fun. Cause you know, this sale is looong, and the island is lonely, we need to have some fun interaction along the way.
