Do we know who robo kid is? Seems weird that someone managed to do this since it seems most ppl in the new world are mostly technological illiterate except for dead doc, shiro and Robin
Given the cruelty needed as well I'm guessing robin did it
Was there some relevancy to the change in the style of cups the master made?
They used to be dark and narrow and straight edged and now are more round and colorful like the bees?
