I believe Kimba may have been a possible influence in some regard(at least prior to Roger Allers coming on board and changing the story to the Hamlet-esque plot). However, a lot of those "scene comparisons" are absolutely utter nonsense or just grasp-strawing. The only single one that's worth noting is the lion in the clouds similarity(although Mufasa appeared as a ghost in the clouds, whereas the Kimba one's just a cloud formation). A good example of this article just trying to trick people into thinking that it is a rip off if that cliff dangling comparison. In truth, Kimba is actually just trying to climb out of a small hole with a spiked trap at the bottom of it, and the female lioness herself gets herself caught in trouble soon after that. A lot of these comparisons are pretty much just a classic case of grabbing similar looking screen captures, and pairing them together out of context to fool people into thinking the scenes themselves are exactly alike. I have no doubt that Kimba played some influence very early on in production, but plot-wise, they're significantly different at the end of it. This old article really needs to have a bullet put its head. It's caused so much damage and warped the whole thing into an unnecessary "rip off" controversy.
