Is it me or did Kuma and Mogura just kinda come out of nowhere?
By the way, their designs are nice. I'm just confused as to how the Zyuohgers got them, because I think only Kirin had a real story to it.

Yes, they did. I think there is a pattern here though. Kirin was a cube that looks like the King's credential. Mogura was in giant cube form. While Kuma was in weapon form. Somehow i think Komori will debut in animal form first
