From ThreeA Wiki
Harold, most commonly referred to endearingly by fans as Harold the Fucktard, is a robot created by Rothchild. The Harold AI is known to be extremely faulty and this is represented in more than one story in the WWR Books. The term Harold the Fucktard comes specifically from a story from the first book where Harold is specifically the main focus.
This robot has not yet seen release in figure form, but we do know that he is in production. He sports two RPGs for arms and is mobile via tank treads.
