But when the Omnitrix starts behaving strangely, Ben begins to transform from one alien to another without being able to stop. Part Two: As the Omnitrix is still uncontrollable, Ben asks a mysterious friend of Max to repair it. But when three bounty hunters — Tetrax Shard, Sixsix, Kraab — land to recover the watch, Ben has to try and fight them despite his current predicament. Part Three: The gang heads into the forest to prevent Ben's transformations from causing too much damage. Meanwhile, Vil, who seems to be the same species as Gax, lands nearby. He helps Ben discover his powers, but Ben quickly realizes that this new friend is in fact an opponent. Vil brutally locks Gax, turning Ben to human form, and restoring his true form, the intergalactic warlord Vilgax, who quickly defeats Ben and the three bounty hunters, who are revealed to be fighting against Vilgax. This also results in Ben eventually switching through all his aliens, unable to revert to human form. Part Four: After his meeting with Vilgax for first time, Ben continues to transform rapidly without stopping or being able to revert to human. While Vilgax tries to take the energy of a volcano to recharge his ship and return home, Ben gets the idea to "upgrade" the Omnitrix by modifying it with Upgrade itself, giving him enough power to rapidly shift through his transformations and defeat Vilgax to save the earth. Omnitrix alien debuts: Gax
