It is Kopa/Kula. I'm sorry if that's not okay.

Brown Wolf: I do know that, but you do get some couples like that on the site. Take the most common one for example, Kovu and Nala. People are a fan of them (I personally am not one, but no offence intended for any Kovala fans out there) even though Nala is old enough to be his mother. Personally I can only stand one generation apart, but I don't really like couples more generations apart than that (for example, a what if moment here, Scar X Kiara) because that is a bit too old, but, whatever. All I am saying is, it is common for people to make fancubs where the parents are one generation apart (honestly, I don't know why I had to complicate things) and put them up as guess the parents fancubs.
Plus adding to this (sorry about this! I tend to talk a lot!) SkyeNoMite did say that the father was Kopa. The cub doesn't look like Kopa, so it is easier to try and narrow it down to the cub got it's looks from it's mother (although it could be just a case of genetics, but that does make it a bit too difficult) and as far as I am concerned, most of the dark lionesses have already been suggested and they were wrong. There are mostly light lionesses in the film and in the books, after all

Is 1# is KulaXTojo?

#1 couldn't be a KopaXKula cub. Mainly for the simple reason that Kula is old enough to be Kopa's MOTHER! I think #1 could be the cub of Kula and Tojo.

is 1 Kopa X Kula? I don't mind if I get the cub or not, I just like guessing!

KiaraXKovu

none of these, sorry? Want a hint?

KopaXKiara/KopaXSarafina/KopaXNala/KopaXZira/KopaXSarabi? I am trying for 1.

The father is Kopa

#1. Kovu/Kiara? Kovu/Nala? Kopa/Vitani? Scar/Sarafina? Kopa/Kiara? (In some people's versions, they aren't brother and sister)
