Mouse and Supermouse: Petey Pate builds Supermouse robots to replace Mighty Mouse, but they become corrupted, so Mighty terminates them.

The Bride of Mighty Mouse: 20 years later Mighty is married to Pearl, running a motel and raising their son, but is threatened by Howard Hack (a parody of Howard Roark from Ayn Rand's The Fountainhead) rivaling with his own motel.
