The Chauffeur

The Chauffeur (real name unknown) was a driver and bodyguard under the employ of Tombstone. She was seen several times throughout the show driving Hammerhead around.

Background in other media
It has been speculated that the Chauffeur may in fact be Myrna, an obscure character who debuted in the Amazing Spiderman #114 (November 1972) as Hammerhead's moll.

When asked by fans if this theory was true, Greg Weisman refused to confirm or deny it.
