So, Goku has a non-canon move specific to Super Saiyan 3, in which he punches forward. Out comes a golden dragon, said dragon wraps around bad guy and spins around and around.
The art of Blue with Discord made me think of it.
I went with the beginning punch pose. There's a second one where Goku holds his fist up triumphantly at the end.
Discord was supposed to be the dragon, but it looked absolutely terrible. I could add the spiked band things, later. I tried on the right (arm?) And it didn't look all that great.
