I was hanging out on CBR's Black Panther thread and someone posted a scan of T'challa winning a tribal challenge and immediately went... DAMNIT!
I am not a big Kirby fan, so I haven't read his BP story more than a couple times. So I completely forgot about the few panels at the beginning of #8 that detail T'challa winning the throne for the first time.
So, I have gone back and edited Panther Powers #3 to reflect the new information I found.
It is hilarious that you research and read and read and search and read for a post and then find something a week after you finish it. Oh well.
