A link in one of the comments on one of Nadra's pictures on TLKFAA led me to a site dedicated to archiving Disney comics, including -- naturally -- Lion King comics.
However, my excitement at this was short-lived, since the archive only seems to have tiny scans of the first pages of each comic. Many of the TLK comics have already been translated into English (like the ones with Malka, King Joe, etc.), but a lot of them are completely new to me, and I'm sure to many others. Here's what I found when I searched for "Simba".
(Interesting how the English translations of some of the titles are quite different than the ones we've grown used to, i.e., "New Kid on the Block" instead of "Simba's New Brother", "Tojo's Tiny Tots" instead of "The Orphaned Birds", etc.)
It's kind of painful, seeing these tiny hints at these comics that could reveal even more new semi-canon characters, yet there doesn't seem to be any was of accessing them. One of the comics even features a female hornbill that Zazu is infatuated with (looks like Binti's got some competition!)
Anyway, just thought I'd get this out there.
EDIT: The comics in this list that are complete and translated can be found here
(except for "The Family Tree", which you can read here
