This is supposed to be him during/just after his first fight against Reborn Garmadon.
Also I know that the ninjargon on his gi in this drawing says “energy” and not “ninja” like it does in the show, but I added that part last night when my only reference was a Lego magazine and not actual pictures from the show so please bear with me.
Also a video will be coming out on the channel tomorrow of the process of drawing this so look toward to that!
