Something just popped into my mind about Vitani.

[Elton John]

You know how the second born cub of the royal family gets to lead the lion guard?

Now I don’t remember if she had that mark or roar powers but... if she did....

Nuka was first born which would make her second born.... to Scar... meaning Zira and Scar were mates....

Assuming my memories of Vitani having the power of the roar be correct...

[Stormy]

iirc she only gets the mark and roar after Kion gives it up. before then no, because she talked about not needing the roar to lead the guard when she was up against Kion.

so i dont think she had it originally had it while the old guard was gone. they kinda just took over themselves without any sort of mark or power.

ahaha

my memory failed me
