He'll always be Kopa to me.

Here is a theory about Fluffy aka Tanabi in my opinion as well as another theory:
Fluffy was just a nickname to Prince Tanabi, but the cub disliked it. Tanabi was bullied because of that nickname which was given by Simba. Due to this, he bonded more with Nala [his mother] then Simba [his father]. One day Simba lost his temper and clawed Fluffy/Tanabi's face giving him a scar on his left eye [which looked a lot like Scar's scar] due to disobedience. Tanabi ran away later that night and never returned which made Simba regretful. Three days later, the pride found Tanabi dead near the outlands [although Tanabi was faking it] and they were all upset but Simba was the saddest. Zira was the one who attacked Fluffy/Tanabi and was exiled for it [think of Not One Of Us but it is about Zira and the animals are more furious, oh and a cheetah gives Zira the bite/scar on her ear]. Tanabi woke up after everyone was gone and left and started his own pride and had twin cubs with a white lioness named Abla.
Kovu and Kiara's cubs theory:
Kovu and Kiara became queen and king and their cubs may have been Nyeusi, Adia, Tanabi Jr., and Erevu/Shani II.

As I said in MY THEORY Kopa is Fluffy, so please don't try to explain everything to me it's MY theory not yours.

Kopa doe not exist in the movie universe

In my theory Fluffy is Kopa, because they both have ear rims, orange fur, and other things similar to baby/cub Simba. Therefore, I believe Fluffy's true identity is Kopa.

The page was created because it's a genderless cub that was later changed to Kiara in the sequels, and directors (jokingly) named it "fluffy" (and people in TLK fandom tend to freak out over every single lion character).
But people naming their fancharacter based on this cub "Fluffy" is indeed weird xD

its name isn't really fluffy...during the commentary they just named him that as a joke but oh well

Disney said the cub was genderless

Lion King verse is too complicated.

SOOOOO CUTE
