Trade-Off is the thirty-seventh episode of Ben 10: Alien Force.

Plot

The episode begins with Darkstar studying in a warehouse when Kevin breaks in. Kevin wants to send Darkstar into the Null Void, but Darkstar quickly defeats him and says that he wanted Kevin to find him due to the fact that both of their lives depended on it.

Darkstar releases Kevin on the condition that he listens and he says that he has discovered an artifact called the Dominus Librium that will transfer their energy in order to make both of them normal and neutralize their powers. However, it is on an island and he needs Kevin to help him retrieve it. Afterwards, Kevin agrees to help Darkstar. Meanwhile at Ben's house, Ben and Gwen try to call Kevin but he doesn't answer. Ben transforms into Jetray and he flies with Gwen to a mission. Darkstar and Kevin arrive at the island in a hovercraft and enter into the temple where the artifact is located and it is flanked by ugly statues. Kevin triggers a booby trap that brings the statues to life and they attack him and Darkstar. Kevin and Darkstar fight with them and retreat. They enter into the temple. The statues are too large to follow them. While they are inside, Kevin and Darkstar discovered the Dominus Librium and Darkstar tries to retrieve it, but it is protected. Kevin goes up to it and is able to take it. Kevin is closed in two enormous hands of a statue surrounding the Dominus Librium.

Darkstar frees Kevin, who has the Librium. The temple starts to collapse and Kevin and Darkstar run, while barely escaping, and evade the statues. The island floods as Darkstar and Kevin get into their hovercraft and fly away. They enter into an isolated spot and use the Dominus Librium. The Dominus Librium works on Kevin and Darkstar and they are transformed back into normal, although their powers are gone. Then, Darkstar punches Kevin, takes the Dominus Librium, and tells him to stay away from him. That night, Kevin arrives at Ben's house and presents that he is human and powerless. Gwen is concerned about Kevin's black eye, but he lies about it. The team drives to a warehouse to fight the Forever Knights. Gwen tells Kevin to wait outside due to the fact that his lack of powers make him a liability. While inside, Ben tries to transform into Humungousaur, but he transforms into Big Chill instead. Big Chill and Gwen fight the Forever Knights and Kevin comes inside and fights them as well. The Forever Knights attempt to flee, but Big Chill freezes their truck and transforms into Ben. Kevin reveals that he sabotaged the engine and Ben admits that Kevin is still an important part of the team. Later, Kevin asks Gwen to do something with him, but she senses Darkstar in his aura and declines.

  • The plot of this episode, mainly Kevin's role, is similar to The Thing from the 2005 Fantastic Four film, in which The Thing is assisted by a villain in reverting to normal from a disfigured form, but decides to re-mutate himself in order to save his friends from the same villain.
