New guy kinda gives me Saga vibes because of the color scheme.
I don't know if it's because of his colors, because he is the 6th rider or something else but I really have a 6th ranger feeling when I look at him. Like he is the real rival of the hero or something, the one who will grow and get power ups on par with Zero-One.

Gold with blue eyes + Caucasus could also be a reference to Kabuto.
The show has a lot of common points with Kabuto
