Simba's pride and Kanu's pride's evil leader will go into war.
During Kanu's stay with the Pridelanders, he'll fall in love with Vitani in which even after the war with the evil rogue is over Kanu will decide to stay with the Pridelanders. Also, the evil rogue that held Kanu's pride hostage met a lone lioness walking near their water hole. He decided to let her stay and they fell in love. The evil rogue's name is Kia and the lone lioness he found's name is Zuri.
In the 100 chaptered sequel, it's about Zuri trying to get revenge for her mate Kia because Simba won the war and killed Kia.
She found an abandoned cub by the name of Chaka and will raise him to kill Simba and Kovu.
It won't happen because Chaka will eventually fall in love with Akeyla and despite the two pride's fuels with each other, they'll secret meet.
They will be in love and just like Kovu and Kiara, they'll stop the war between the 2 prides. (Spell Akeyla's name Akeylah instead but pronounced Akeyla).
I'm thinking that maybe Rami and Binti can run into a male Leopard cub by the name of Amari and become best friends with him?
