Many annoying コメント from ファン who believe Kopa is Fluffy which isn't true.

Here are 10 different コメント from them from Youtube:

1. "that can't be Kiara, in these 映画 the males are yellow and the females are beige-colored, and that baby is yellow."

2. "that's there first child Kopa....he is a boy and Kiara's older brother."

3. "ok at the end it is not Kiara it is Kopa before the making of the lion king 2 they changed it 2 Kiara instead of being it Kopa =3."

4. "I am not a ファン of lion king, but still kopa is true!"

5. "the cub is not Kiara. It's supposed to be Simba's and Nala's son, Kopi. The reason he wasn't in the 秒 because he died as a cub. Sad I know. Look up on the story of Kopi. You'll learn more. Sorry to be a downer."

6. "OMG KOPA" XD (pointing out at Fluffy)

7. "2:18 Here comes Simba and Nala's cub, Kopa. That cub is not really Kiara (I'm not wrong). Kiara is really born on Lion King 2: Simba's Pride."

8. "Kopa, actually. または that's the most "official" name we have for him (comes from a series of 本 published the same 年 the film was released). He got cut from the sequel (where his name would have been Chaka). That's why the majority of ファン use him to fill the plot holes in Simba's Pride. The only thing we're clear on is that "Fluffy" there is clearly NOT Kiara. He has ear rims, he's younger, he's presented later in the day, and he's male, indicated によって his belly fur."

9. "That cub at the end isn't Kiara, that is a male cub named Kopa. Kiara is born in Lion King 2. Look at the ears of this cub at the end. He has もっと見る golden color, has a bit hair, dark stribs around his ears and a もっと見る red color nose. If あなた look at Kiara in Lion King 2, she is もっと見る light. She does is もっと見る light, but does not have dark stribs around her ears and she has a darker nose."

10. "Kopa is the baby cub they 表示する at the end.....he is the first born child of Simba and Nala but the people at ディズニー didn't use him in the 秒 Lion King, but they used Kiara, Kopa's young sister......he is in the 本 and if u just 検索 on youtube, "Kopa's Story" it will give a pretty good explanation of what happened to him."

But there's also ファン who know that Fluffy is Kiara.
Which considers that they been ignoring the 本 and comics. :)

Well, the Kopa believers can't hold their breath, since TLK filmmakers ignore the 本 and ディズニー doesn't want Kopa または any of TLK:SNA non-canon characters be part of the film. Known these 本 are from the outsider illustrators and the creators of these 本 never worked with the ディズニー Co. Alex Simmons who created Kopa and the 本 he exist in says that Kopa is his creation all the way.

Disney has made it clear that Kiara is Fluffy and no one else.

Kiara's original デザイン makes her look male によって her pelt color and black rings on her ears.
But that doesn't make Fluffy (Kiara) being male just because of it's markings and colors.
Kiara looks somewhat like her grandmother, Sarabi によって her ears and her pelt color can be created for females as well as known reality lions of both genders are the same Colors（色） and being golden yellow, a 雌ライオン, ライオネス can be created the same.
Chances of all, Mufasa can be taken after his mother and Scar taken after his father, since TLK:SNA 本 aren't canon. Mufasa's mother could possibly have a golden yellow pelt color like him. So, that can't make Fluffy being a boy によって the pelt color. によって Fluffy's belly 毛皮 doesn't 表示する were it ends since it's chin is covering it.

But now that Simba is having a second-born cub, a male named Kion in a new film/show called "The Lion Guard which will be aired on ディズニー Jr in 2015. Kion will be an official TLK character unlike Kopa which is just a profit fiction character in just a few 本 that are release only in USA and no were else with Disney's stamp placed on them.

Here are some of the 名言・格言 and many other official stuff about Fluffy that is true:

"You think it's a king but it's a queen" によって one of TLK 2 creators on a magazine.

"Here's Fluffy, Simba's and Nala's little cub. Let's just end it on Fluffy" One of the filmmakers of TLK on the 1995 commentary laser disc.

"Rafiki welcomes her to the サークル, 円 of life." one of the golden 本 of TLK.

Fluffy's appearance in the TLK 2 trailer for baby Kiara.

名言・格言 from TLK 2:

Timon: "Ah, Pumbaa, look at that little guy. a chip off the old block. and あなた gotta know who's going to raise him."

Pumbaa: "His parents?"

Timon: "Okay sure, get technical. but who's going to teach him the really important stuff? like how to belch (burps) and dig for grubs? I'm telling ya buddy.. it's gonna be like old times. You, me and the little guy."

Rafiki: (chuckles) "It is a girl."

Timon: "Girl."

Timon & Pumbaa: "GIRL! Oy!"

Nala: "She's just like あなた when あなた were young."

Simba: "Exactly, do あなた realize the danger we put ourselves into?"

Nala: "You mean the danger, あなた put us through."

Kiara is well much like her father being mischievous like Simba as a cub.

Kiara will grow up to become a royal クイーン she will find her king and take her place as queen.
