Partners with Rhino, Mugsy was one of the Ventriloquist's henchmen. Being the more subtle of the duo, Mugsy and Rhino assisted their boss in two occasions. The first one was when Scarface committed several heists with clockwork precision, which attracted Batman's attention.
A tall, thin, wide-eyed man, Mugsy was apparently the only member of Scarface's gang who fully understood that the Ventriloquist and Scarface existed as two separate personalities in the same body (that of the Ventriloquist), as evidenced by his refusal to execute the Ventriloquist on Scarface's orders after Scarface suspected him of betrayal.
