Not so long ago I just noticed he has the same tail design as Rumble.
And yes, He is. But the color line are swapped. Rumble mane are for the upper lighter grey and the lower one is darker grey and the tail for the upper one is lighter grey and lower one is darker grey. Cyan one the other hand is the reverse for the tail upper emerald, the lower azure and for the mane are upper azure while the lower one is emerald.
So cute! I love his design! :3
