Belladonna (the evil grinning lioness at the top) has nothing in common with Zira. In one episode, Belladonna is in alliance with Tonga to kill Kimba, and when she meets him, she pretends to be Kimba's aunt, and tries to knock Kimba who ends up hanging off the edge of a cliff (hence the picture). At the end of the episode, Belladonna asks Kimba for forgiveness and dies, and Kimba pursues Tonga.
Meanwhile, Zira has her own motive to kill Simba, and never seeks forgiveness for her actions. Given the heat Disney took for supposedly plagiarizing
Kimba the White Lion with the first movie, it's highly unlikely they would do it again for the sequel, and believe they'll get away with it.
