|Head||8-bit sonic head|
It has a red poptart, red feet with white tips on, a red tail, and an 8-bit version of Groudon's head.
The nyan flies through space and trails the default normal rainbow. The exploding stars remain the same.
There is currently no other versions of nyan Groudon anywhere else.
Sadly, this nyan cannot be found anywhere else, but it could have been once on YouTube and then was unfortunately taken down. This makes both the origin and the theme for this nyan unknown.
