- "His type usually end up in one place: jail."
— Jeff Tracy
Warren Grafton is a villain from Brink of Disaster.
Grafton was a greedy, scheming businessman who tried any way possible to get rich quick, even if others had to suffer. He became the President of the Pacific-Atlantic Monorail Corporation, but started the business without obtaining the necessary permits.
He visited Lady Penelope hoping she would invest in his latest project: a fully Automatic Monorail. Whilst he was waiting in the library, he located Lady Penelope's hidden safe that contained her priceless jewel collection under the floor and jammed the alarm systems.
After Lady Penelope refused to invest with him, she let him know about another business man interested in transportation named Jeff Tracy. After getting in touch with Jeff, Grafton calls a meeting with his fellow business men who were dangerous criminals. Two of them, his chauffeur Malloy and another man named Selsden would go to Creighton-Ward Manor and steal Lady Penelope's jewel collection whilst he is in America discussing business with Jeff Tracy during a trip on his latest monotrain.
Soon the automatic monotrain is taking its journey, Jeff is also accompanied by two of his associates Brains and Tin-Tin. Grafton tries to assure them that there is no danger on the train, even showing the main automatic control unit, but Jeff and the others aren't convinced, rightly thinking that he cares more about making money than people's lives.
Later a thunderstorm strikes down one of the safety helijets that was observing the monotrain and the impact of the fallen jet destroys most of the bridge and cuts off the automatic signals causing the monotrain to go out of control.
Grafton panics and can think of no way to prevent this disaster. Jeff calls International Rescue and Brains, after several attempts manages to slow the monotrain down.
After being saved by International Rescue, who carefully lift their carriage off the bridge and set them down safely on the ground, Jeff tells Grafton that he will be pressing charges for this act of criminal negligence and he, along with rest of his cohorts, including Malloy and Selsden who failed to burgle Creighton-Ward Mansion are imprisoned.
- In the Young Corgi novelisation, he is called Warren S. Grafton.
