Love this fusion it looks amazing. But I'm curious are you doing more with this character. Sense dbs is giving higher forms for everyone maybe you could have this fusion have ultra instincts and a few more things adding onto the design do to all the odd powerups they are giving everyone and maybe it could have another character in the fusion like merged zamasu or who he was based on Xicor. The fact he is a half saiyan and half Kai means he would naturally make God ki and can get zenkai boost far better than merged zamasu. Also he have ssj4 and ssj5 so it could make it seem even more menacing.
