Perfect Day is the fortieth episode of Ben 10.


Ben seems to be having a perfect day: a bus full of cheerleaders breaks down in front of him, unreleased games fall off a truck and Grandpa Max makes food Ben considers edible, to which he unleashes an explosive belch, rumbling the ground, right in front of Gwen.

However, when another Gwen and Grandpa Max show up, they claim that the other Grandpa Max and Gwen are impostors planted by Enoch. Then Lieutenant Steel appears and claims that the two aren't really Ben's relatives and they are Limax sent by "Vilgax". Vilgax appears trying to trap Ben in the Null Void using a projector. Ben defeats "Vilgax" and aims the projector at Gwen and Grandpa Max (still not believing the two).

Gwen tells Ben that if real "Vilgax" came, he would try to steal the Omnitrix first. Ben's convinced that Grandpa Max and Gwen were telling the truth so he discovers that Enoch and the Forever Knights have trapped him in a dream world while they attempt to remove the Omnitrix from his wrist. Everything that happens to him during his dream was warped to make it better: the bus of cheerleaders saw him wearing his blue-and-red sumo-slammer boxers for example.

It was turned into a scene where the cheerleaders adore Ben (as Diamondhead). Revealed, Enoch (removing his Lieutenant Steel disguise) turns the dream into a nightmare... Ben's school!

Ben, Gwen and Max chased around by monster versions of Ben's nemeses such as Kevin 11, Cash and J.T. Ben figures out that his dreams are to his mind's command. After managing to take control of the dream and escape, Ben traps Enoch in his own dream world. After leaving, another Forever Knight, the "Forever King", decides to leave Enoch to his fate because of one too many failures and decides to finish off the Tennysons himself.
