I always assumed it was Toyman, he's had a few different incarnations over the years. But AFAIK his name is never actually mentioned in DKR.
I can't find any reference to Toyman or any other villain in the credits on IMDB.
There's a discussion about his identity on Wikipedia, it seems to be a bit of a mystery...
What is the name of the Joker's accomplice? His name is not mentioned in the article, but he plays a fairly important role in the story, first sabotaging Two-Face's bombs and later aiding the Joker. I'm not an expert on the DC Universe, and all I know for sure is that he's not a really well known villain, and that his trademark seems to be making dolls that explode. I currently don't have access to my copy of DKR, but if someone could check to see if his name is mentioned, I think it would be worth mentioning in the article. Smooth Nick 04:13, 5 June 2006 (UTC)
I can't find mention of a name with a quick scan of DKR. But that sort of thing is typical of DKR, he might be a regular Batman character with a name mentioned somewhere else.--DCAnderson 04:25, 5 June 2006 (UTC)
Is it Humpty Dumpty? It certainly looks like him but there is nothing in the book to actually say either way or the other. 13:27, 9 July 2007 (UTC) Sorry, never mind I had just stumbled upon that and was struck by the resemblance. I didn't think to check the date of his first appearance. Hamptor 13:31, 9 July 2007 (UTC)
