It's not Taka. It's only a fanfiction name made up oleh an outsider childrens' book writer, while Scar's creators ignored his book, and downright denied it on the commentary track oleh calling the cub "Fluffy" instead of tieing the book in.
The film makers have never revealed their own official original name for Scar.
It's left up to fanfiction, profit atau non-profit.
scar has no other name but "Scar". There's no official name diberikan to Scar but a few outsiders who created TLK:SNA buku that diberikan him the name, "Taka" which is not official to disney and is completely ignored from the Walt disney company.
