Character appearance and disabilities
Fictional character biography
Harold is a mute hunchbacked man who is expelled from his house in Gotham City and subsequently travels to Hub City. Initially his full name is not revealed and he goes only by 'Harold'. His first appearance in a Batman comic occurs the first part of the story arc Penguin Affair. Harold is initially cast as a henchman for the Penguin, who had conned Harold to work for him and build deadly machines with which he could threaten Gotham City. Months after putting an end to Penguin's scheme, Batman finds Harold in an abandoned building and saves him from a mob of angry parents have mistaken him for a child molester due to his appearance.
After rescuing Harold, Batman gives him a home and a position in the Batcave, working as a technological aide in his war on crime. A diary entry in 'The Batman Files' explains Alfred's first encounter with Harold. The newcomer is delighted to have advanced technology to work with while Alfred has doubts. Batman explains Harold's poor living conditions and Alfred is pleased at Harold's rescue.  Harold's assistance continues even after Bruce Wayne is disabled while fighting the villain Bane in the Knightfall storyline. Harold builds a unique wheelchair for Wayne, which includes multiple surprises such as emergency shelter. During the story arc Knightsaga, the new Batman Jean-Paul Valley ejects Harold, along with Ace the Bat-Hound and Robin, from the main Batcave. Harold and Ace managed to sneak into a hidden subsection of the cave where Harold continues to work there, eventually aiding Nightwing, Robin, and Bruce Wayne to retake the cave from Valley. Harold resumes his position as Batman's technological aide and also designs a new costume for Nightwing. He worked with Azrael (Jean-Paul Valley) by request of Batman for a time before the death of the former. During this time he live in Azrael's new home, a converted castle. 
Hush saga and death
In the storyline Hush, Harold had been tricked by the titular character into undergoing surgery to repair his voice and his stature. In exchange, Harold was made to place a hidden circuitry relay onto the Batcave's main computer which gave off subliminal signals which affected Batman's mind. Harold attempts to reveal Hush's identity to Batman, but Hush prevents this by shooting him fatally. In his final words, Harold states "I knew that even if I had been tricked...you [Batman] are my hero. You would always win." Batman responds that he can forgive Harold's betrayal. He understands how powerful the desire to be happy can be. Harold is then buried in a grave overlooking Wayne Manor. Harold's last name Allnut is revealed by Batman who 'did some digging' and his full name is engraved onto his gravestone.
