Hermes and Barbados have always been rivals, as the latter always wins a competition every time the two have met. In the 3004 Olympics, they competed against each other in the limbo games. Hermes, who hadn't limboed in twenty years due to a traumatic accident involving limbo, wore a Flabo Dynamic Suit. The suit pushed Hermes' center of gravity closer to his knees, giving him a skinny physique which Barbados mocked. As the limbo race began, it seemed that Hermes would win. However, when the suit tore, Barbados won as usual.
In 3008, Hermes' head was accidentally chopped off and had to be preserved in a jar while his body was being repaired. LaBarbara left him and re-married Barbados, as well as having Dwight's surname changed. However, when Hermes used his bureaucratic mind to assist the Earth fleet in retaking Earth from the Nude Alien Scammers, LaBarbara took him back. Barbados swore that they haven't seen the last of him, but then said "Goodbye Forever". As he exited the bridge he was pinned down by the sliding door.
In The Mutants are Revolting, he can be seen dancing with LaBarbara at the Planet Express 100th Delivery Party.
He was seen in The Bots and the Bees where he was sadly looking jealous of Hermes and LaBarbara expressing love to each other before Hermes left for work at their house. In an alternate interpretation of the scene, he was surprised at Hermes' appearance, implying that Barbados and LaBarbara had been interrupted after sex.
He can be a reference about the Jamaican sprinter Asafa Powell.
Barbados Slim is often referred to as a mahogany go
