Acid is a generally hyper-fixated guy, setting his mind to anything, though he doesn't normally always succeed. Acid is easily offended, going as far as to start repeatedly chanting "I am so offended," Acid though can be easily calmed down if someone says his idea was good, if he was already happy, that'll just make him extremely excited. Acid can make his limbs come and go, seen multiple times before, and has a sort of ego.
