The Simpsons Game
Kang (along with Kodos) appears at the end of Mob Rules, when they cause Dolphins to attack humans, cause Lard Lad to assault the industrial zone of Springfield, and invade the mall. However, when they were thwarted, they decided to start attacking Springfield. This causes the Simpson family to enter the game engine to find the creator, but Groening wasn't enough to defeat the aliens because he didn't want to. Soon after God is defeated, God decides to replenish Springfield, returning peace to the city.
