Simba

Simba is the protagonist from The Lion King, its sequels, and the 2019 remake.

Looks
Simba as a cub was a more browninsh-gold colored lion with amber eyes with a cream underbelly, chest, toes and undereyes. The inside of his ears is outlined by a bit of black and the tip of his tail is a bit browner than his mane. Growing up, he also had a few short hair tufts on his head that he referred to as his "mane", but they were the same color as the rest of his fur.

As an adult, he got a bright red mane, like the one from his father Mufasa, but was not yet as large as his late father. In the Lion King 2, his mane had grown and he had matured more, increasing in size and likely strength.
