Tanabi/Fluffy: The forgotten prince

My cub version of that newborn cub that appeared in the end of TLK1 Fluffy that I believe that is also Tanabi, I only believe this because I didn't wanted Simba and Nala to have so many cubs. Tanabi is first born but has been forgotten by his parents, when Kopa was born Simba and Nala only cared about him, Tanabi became a outcast. When Kopa "died" Tanabi was the only one who was happy (besides Zira), Tanabi was jealous of his brother's fame and potential, he also had a crush on Vitani, he was just like Scar, would Tanabi become the new Scar? Should I create a profile for him? I'm also thinking about unite him with my other characters like Naira and the TLK2 plot.
