Whoo, missed that post and a couple of the ones around it completely! So yeah, obviously that's the powersphere OF DEATH.
I really love the Levitz/Giffen era Legion. Not even so much for the plot, just for that shiny, Apple computer-ish clean lined vision of how the worlds of the future look and function. I've been looking at a few old Superboy & the Legion issues the last couple days and all the elements are there, but it took that team to really pull them into focus.
