How many cubs does Simba have?

[SweetNala]

Ignoring fan theories, Kiara and Fluffy.
So 2 cubs

So 2 cubs

But, Kiara is the official entity of Fluffy. So, officially (but not canon), Fluffy is Kiara at the end of The Lion King. So, in the official movie universe, Simba has one cub. If deny Simba's Pride in your personal canon, Simba still has one cub, "Fluffy".

Kopa and Kiara. I think Kopa died between tlk1 and tlk2

[WindAnnWise]

As far as I know, he just has one, Kiara.

[Kovi73]

i think that simba have 2 cubs, Kiara and Kopa, but Kopa was kill by zira as revenge for the death of Taka or Scar, well i think that happened

Going off of theories, sub-canon/storyboards, and actual canon, Simba has quite a few children.

Theories:
"Fluffy"
Tanabi

Storyboard:
Chaka
Shani
Aisha

Sub-canon:
Kopa

Canon:
Kiara

(I realize that most of these are just name variations and options that were considered, but sometimes people like to make each one into a unique character. I find it interesting, myself.)

There are a lot of theories that can go with all of these, and many of them can be interesting.

I always thought he had just 2, Kopa and Kiara.. But now I'm starting to doubt that..

I disagree with your categorization. First off, Fluffy shouldn't be categorized as a fan-made (or theory as you put it) character like Tanabi. Out of the cub names thrown around for Simba in the fandom, Fluffy is the most canon of them all, as he/she appears in the canon movie, and was named by the filmmakers that originated The Lion King on the audio commentary.

I would say Kiara is official, as she was directly created by Disney, but not by the original filmmakers, so she can't be canon. In my opinion, I feel Kopa is non-official.

Anyway, your list inspired me to make my own, and here's my list:

Fanon:
Tanabi
Fentali
Naba
Naline
Nyala (sister to Thembekile and Zenani)
Thembekile (brother to Nyala and Zenani)
Zenani (sister to Thembekile and Nyala)

Working Names:
Shani (working name for Kiara)
Aisha (working name for Kiara)
Chaka (working name for Kiara according to this magazine article; supposed son of Simba and Nala for TLKII)

Non-official (in my belief):
Kopa

Official:
Kiara

Canon:
Fluffy

I find it weird that real lionesses give birth to an average of five cubs every two years yet both Simba and Kiara were the only ones in their litter. Simba should have at least twenty before he dies. Poor guy!

Anyway, I think the list that Lion Prince provided is a pretty good representation. However, I'm confused to how Kopa is unofficial. It is true that is contradictory to SP, but saying he is unofficial gives the impression that Alex Simmons requested to make him and Disney granted his request. I don't think that is how it happened. Disney Publishing policies back in the early 1990s would have been the exact opposite. In fact Grolier Publishing (who published the Six New Adventures) acquired Disney Publishing's assets back in the summer of 1994 in a huge agreement. Source: Hartford Courant. August 1, 1994

Chaka (working name for Kiara according to this magazine article; supposed son of Simba and Nala for TLKII)

I don't know if you've seen the email I uncovered by Tad Stones, but it's a second source to confirm Chaka was indeed a working name.

Ah, I think I should've clarified why I put Fluffy in the "Theories" category. He's in there mainly because Fluffy is made into fanon characters from what I've seen, as provided by your own list. But you did compile a pretty good one.
