I have a lot of grievances over how Vitani's Lion Guard was executed in the finale, but I think the one thing that would've saved it [or made it less bs] is to have them all be different animals. Same characters, personalities, voice actresses (and maybe eye-color?), and you can even keep the all-female guard, just different species of animals that would've made the ending come full circle rather than having its narrative be circular.
Like, Vitani's the one-lion on the Guard who's the leader/fiercest.
Shabaha would be a caracal cat since those motherfuckers can jump high and compete with other, bigger predators for food (we were robbed oa caraca, in TLG anyways so this would've been perfect.
Tazama would be a Secratarybird since they can run fast but also have sharp vision as birds of prey.
Imara would be a South African Rock Python, her strength being her coils and jaw vice - In fact, they could've easily saved time and effort by just co-opting the rock python from Season 1, pulling the ultimate Chekov's Gun by turning a background character into a major game player in the finale (also serving as a heroic parallel to Ushari and giving us a non-villainous snake, not enough of which are shown in media)
Kasi as an African Wild Dog (known for their stamina unlike the cheetah, and again, don't get enough appearances in animated animal-based media sans Wild Kratts)
