In Batman: The Animated Series, Rhino and Mugsy were two thugs who joined the Ventriloquist's gang. Named for his hulking size and a tattoo on his right arm, Rhino was the first to join the The Ventriloquist's gang. When his sleeve was partially ripped in a robbery, Batman was able to identify him by the tattoo and confronted him. Rhino didn't tell him anything, but afterwards rushed to Scarface, revealing the villain's identity to Batman. Partner with Rhino, Mugsy was also 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.
