Chaka was the once twin of Kiara (aka Shani), but was dropped from the story early in TLK2's production. There aren't any official concept art sketches of him, so I just combined the best parts of Mufasa and Simba to make this cubby. His colors include Nala's eyes, Kiara's belly and eye sockets, and equal parts Scar, Mufasa, and Simba main fur colors. His other name from TLK production was Fluffy, hence the fuzz.
So a screenshot of TLK2, in an alternate universe. Voila
Here Chaka is with his sister getting the same "everything the light touches" shpeel Simba once received as a cub on Pride Rock.
I like Lion King, what can I say?
