Tell the whole The Lion King story

Not all of you will know that Scars real name is Taka and his dad Ahadi killed his mum Uru and the fact tha Kiara wasn't Simba and Nala's first born, it was a little boy called Kopa who love Vitani and was killed by Zira to get revenge for killing of Taka (Scar) ans in the second film with Kiara that is why Simba is very overprotective of her, but they don't tell you that, Kopa had a tuft of hair that went darker as he got older so look at the baby at the end of the first film and see the tuft.
