I kind of think it makes sense to call it The Lion Guard since Return of the Roar is the subtitle of the movie/pilot ep. But that's just me, I'm sure either way we can figure it out. I also kind of like having it in the Jungle next to the stuff about the Timon and Pumbaa show since this is also a TV series. And it would be easy to find. And the Hakuna Mata section wouldn't be so lonely in the Jungle all by itself. xD
