Hobsy is a very tall and classy male butler for Mrs. Astor. He is a butler of sorts with a British accent and presumably lives in her mansion in the Waldorf Asteroid.
The Planet Express crew visited the mansion in September of 3010 on their 100th mission to deliver a soufflé Mrs. Astor had ordered from Elzar's Fine Cuisine. Hobsy fed the soufflé to a few dozens of dalmatians Mrs. Astor keeps in an isolated room. However, as the souflée contained a few drops of dangerously explosive nitroglycerine, the dogs who ate it could have been badly injured, or even killed.
He was later seen in the New New York with his boss, who demanded that Mayor Poopenmeyer cleaned up the city from the sewage left on the streets by the sewer mutants, and assisted the official declaration of mutant freedom.
