Henchman 24 is a recently deceased Henchman of The Monarch, the arch-nemesis and rival to Dr. Thaddeus Venture, father of The Venture Bros. (the title of the adult swim television series).
Henchman 24 is notorious for his strangely pitched voice, his lanky build, and his resemblance to Jerry Seinfled, once his costume is off. He is seen most frequently, in fact always, with Henchman 21, his cohort and friend.
Henchman 24 is killed by a car bomb when he mistakenly gets his seatbelt stuck in what was supposed to be a parked Monarchmobile.
The Monarch has not only hired Henchman 24 as his henchman, he at one time was a "Shadowman" with him under the employ of Phantom Limb, during his time with the Guild of Calamitous Intent. At that time, Henchman 24 was known as Shadowman.... 24.
He currently haunts his old friend, 21, though it is still disputable as to whether or not he is in fact a spirit returned from the dead or a figment of 21's damaged psyche at the loss of his one and only friend.
Henchman 24 ran from Brock Sampsons as fast as his feet could carry him, being his life depended on it.
