Ghostfreaked Out is the twenty-fourth episode of Ben 10.
A boy throws a frisbee and it gets stuck in a tree. The boy climbs the tree to get it, but can't come down. Ben and Gwen show up and see this, and Ben becomes Wildmutt to climb the tree and get the boy. Wildmutt strangely talks just like Ben and tries to reassure the boy, and the boy turns around, having Ghostfreak's eye and in Ghostfreak's voice, he says that he wants to be let out. The whole setting changes to a giant Ghostfreak and giant Ghostfreak tells Wildmutt to let him out. Ben suddenly wakes up and falls out of bed. The whole thing was a nightmare.
Ben begins having strange feelings about Ghostfreak, as Max drives Gwen to a school she wishes to attend, Bancroft Academy. Ben callously calls the school a "school for snobs and posers". Upon arriving at the school, they are given a tour by a snobby student named Tiffany. During the tour, Ben begins to see strange things, such as Ghostfreak's shadow and Ghostfreak's eye in a beaker, telling Ben to let him out. Ben's behavior is making Tiffany start to think that Gwen isn't Bancroft material and Gwen was about to punch Ben until they hear a noise coming from the gym. It's the Circus Freaks, and they have come to rob the school.
Ben arrives and the Circus Freaks recognize him. Ben tries to become Heatblast, but transforms into Ghostfreak. As Ghostfreak battles the Circus Freaks, Gwen and Max notice that Ghostfreak is fighting very viciously and not the way he fights his enemies at all, even scaring Gwen in a strange manner. The Circus Freaks escape, and Ghostfreak gives chase.
The Omnitrix times out and Ghostfreak reverts to Ben, but Ben realizes that Ghostfreak has escaped the Omnitrix. Ghostfreak explains to Ben that he has entered the Omnitrix to possess Ben in order to take over the world and has now been freed from the Omnitrix. Zs'Skayr removes his second layer of skin, revealing his true form. However, Zs'Skayr has also revealed a new weakness; his real body cannot resist light. Ben escapes from Zs'Skayr's clutches. Zs'Skayr then possesses a Bancroft boy playing a tuba and realizes he can't be destroyed by sunlight when he's in a host body. Zs'Skayr finds the Circus Freaks hiding in a shed and makes them his minions by possessing Thumbskull, throwing him around as a threatening tactic. Ben tells Gwen and Max about Ghostfreak escaping and then they begin searching the school for him.At night, Ben notices some Bancroft students running away screaming and becomes Four Arms to see what's going on. The Circus Freaks come out, with Zs'Skayr possessing Acid Breath. He leaves Acid Breath and tries to possess Four Arms, but realizes he can't possess Ben in alien form. Zs'Skayr then possesses the Circus Freaks to fight Four Arms, but Four Arms defeats them all. Zs'Skayr then possesses Gwen and fights Four Arms. Zs'Skayr as Gwen climbs up a wall and Four Arms follows, reverts back to Ben. He holds a sungun at Zs'Skayr, but Zs'Skayr tells Ben he will make Gwen die unless Ben surrenders to him. Ben decides to surrender, and Zs'Skayr leaves Gwen, but has the Circus Freaks battle Gwen and Max.
Ben becomes Grey Matter to avoid being possessed by Zs'Skayr and then begins to make the Circus Freaks fight each other. Zs'Skayr then chases Grey Matter into the clocktower. Grey Matter soon reverts to Ben and Zs'Skayr has another opportunity to take over Ben. But sunlight approaches and Ben pulls down the curtains. With the sunlight revealed, this kills Zs'Skayr. The police come and arrest the Circus Freaks, and Gwen now has no chance of attending Bancroft Academy. Ben cheers her up by saying none of the students would have been able to stop Zs'Skayr or the Circus Freaks, while she could.
