So, I was thinking of a Boss and Enemy battle sprites!
I made a Snarbolax sprite concept drawing, with a attack details and other things, but i currently have no way to upload it QQ.
I was thinking this Sprite could move on the ground along with the other sprites like Jelly King and Vanaduke. They would have a mind of their own, with a Battery bar, which would act like a health bar! They wont die, but will come back to you when at 0% and recharge
(1 minute to recharge fully at level 50)
