Hudson is a friend that Stewie makes in the park in "Pal Stewie".
While trying to assassinate Lois with a drone, another boy named Hudson interrupts Stewie and stops his plot. They quickly become friends and when Stewie shows him his weapons collection as part of his attempts to kill his mother, he is convinced to give up his plans so that they can stay friends and buries his weapons. But at preschool, Stewie discovers that he's the only one who did not receive an invitation to his party and decides to get revenge.
Stewie manages to knock out all of the other children at the party and confronts Hudson where he discovers that he did receive an invitation but never responded back. Brian arrives and reveals that he destroyed the invitation because he didn't want to lose his own friendship with Stewie, who points out that they are more than friends in being family.
Hudson is voiced by Andre Robinson.
