Sunset Dragon seems fitting (8th Gate).

[Megatolium]

Since it's in NB, why not discuss it?

Why is it fitting? A sunset, especially a red sunset is an sign of death in Japanese culture.

And 8th Gate ends in death.

Morning Peacock = Green

Afternoon Tiger = Blue

Sunset Dragon = Red

I'm calling this Higureryuu lol

So, what's Higureryuu gonna be like? Remember that Hirudora and Morning Peacock actually resembles its given animal.

Maybe Dragon Fist? Lol

I think it is going to involve his nunchuck

The pelvic thrust of death

Scrotal rupture of doom.

If it turns out to be Dragon based, it would most likely be Sunset/Midnight Dragon.

Asakujaku: Morning Peacock.

Hirudora: Daytime Tiger

It has to do with the time of day, and since Death would be the end of they day, Midnight or Sunset would make sense.
Also I think it'll look like Master Chen's Leaf Dragon God

But red, due to Madara stating that Guy had to "Use the Red Mist."
I think it's gonna be awesome!

Nothing is blue, Bad translation by Manga panda. They even stated it was green in the past. It is all "Green" hence the nick name "Green Beast" never "Blue Beast".
