The Visitor is the eleventh episode of the third season of Ben 10, and the thirty-seventh episode overall.


A mysterious alien named Xylene shows up and wants to return the Omnitrix to its rightful owner, Grandpa Max!


In an arctic landscape, two men riding snowmobiles come across a strange pod in a snowbank. They accidentally open it, and an alien named Xylene exits from it. They become afraid and run away.

Meanwhile at a park, Gwen flies a kite when Wildmutt steals it. She casts a spell on him that causes the dogs in the area to be attracted to Wildmutt. They swarm over him and Wildmutt runs as they chase him. Wildmutt climbs a tree, but the branch breaks and he reverts back into Ben. Ben and Gwen notice that Max looks sad, but he denies it, and says that he needs some time alone. Gwen drags Ben away and explains to him that her mom told her that Max and their grandma first met in St. Louis, so Gwen figures that Max must be feeling kind of lonely without her. Suddenly, the kids at the playground panic as Xylene is present and grabs Ben telekinetically, demanding the Omnitrix. Ben transforms into Heatblast and attacks her. She fights him with telekinesis, but Max arrives, and Xylene recognizes him.

Back at the snowbank, the snowmobilers, along with others, go to the site of the pod, and one of Vilgax's Mechadroids emerges and attacks them. It begins to dismantle the snowmobile. Ben dislikes Xylene due to the fact that Xylene hasn't spoken to him yet and seems rather dismissive of him and Gwen. Max explains that they worked together a lot during Max's early Plumber years. Xylene reveals that she sent the Omnitrix to Earth after being attacked by Vilgax. Max tells Xylene about how Ben defeated Vilgax through sending him into the Null Void though much to Ben's annoyance Xylene believes Max is just overplaying Ben's part and that Max had done all the work before Xylene calls her ship. Ben doesn't trust Xylene and follows her and Max as Wildvine. Xylene asks Max to accompany her and help her out in the galaxy, which shocks Wildvine. Then, a giant Mechadroid arrives and attacks Ben and Gwen.

Ben transforms into Four Arms as Max and Xylene arrive back at the Rustbucket. Four Arms attacks the Mechadroid as Xylene telekinetically trips it. Max shoots it, and Gwen casts a spell on it. Xylene throws it into the Rustbucket. It grabs parts from the Rustbucket and adds them to itself before advancing towards Gwen, Max, and Xylene. Four Arms grabs hold of its tendrils and holds it back before being blasted with a laser that causes the Rustbucket to explode. Xylene and Max cause an explosion on the robot that seemingly destroys it, though Four Arms notices it is still active and so tears it apart before apologizing to Max for the destruction of the Rustbucket, not noticing the Mechadroid going into the woods.

Later, Diamondhead, Gwen, Max, and Xylene work together to put the Rustbucket back together and Xylene asks Diamondhead if he's sure the Mechadroid was destroyed which he confirms. At a ranger station, the Mechadroid steals parts from a car and begins rebuilding. As the rebuilding of the Rustbucket continues, Diamondhead gathers the parts of the Rustbucket before he is criticized by Xylene who tells him that a Galvanic Mechamorph would have been more helpful, to which Max clarifies to be Upgrade. Ben becomes irritated at her and Max attempts to calm him down by pointing out that Xylene could try and help him learn more about the Omnitrix but Max taking her side upsets Diamondhead even more and he begins to reach his limits in tolerating Xylene's attitude towards him. He asks why she sent the Omnitrix to him if he's a screw-up. Xylene informs them that the Omnitrix was supposed to go to Max, but a malfunction had caused it to veer off-course and go to Ben instead. Diamondhead is shocked to find he had gotten the Omnitrix by accident and reverts to Ben, which Xylene believes should have been obvious as she wouldn't have sent the most powerful device in the universe to a child. Angry and disappointed, Ben tells Xylene to take it back and cruise around the universe with Max before he runs off, with Gwen going after him. Gwen tries to comfort Ben about the Omnitrix, but Ben tells Gwen that he's more upset about the thought that Max would go with Xylene because, unlike last time, nothing is keeping Max on Earth, which begins to worry Gwen. Xylene and Max continue to repair the Rustbucket and Xylene apologizes to Max for upsetting Ben and reveals that on her planet, her species are left to survive on their own after they are hatched and so she doesn't know anything about interacting with children. The Mechadroid arrives, knocks Xylene away into the forest and grabs Max and flies away as Ben and Gwen return.

Perk Upchuck's debut

Ben realizes that the Mechadroid kidnapped Max to lure Ben and the Omnitrix into a trap. Xylene says that they can save Max if they work together, and the three declare a truce. Gwen realizes that the Mechadroid probably went to the docks and Ben goes there on his hoverboard to find the Mechadroid controlling Max's Plumber suit. Max tells Ben to do whatever he has to to destroy the Mechadroid but Ben offers the Mechadroid the Omnitrix, and Xylene and Gwen arrive. The Mechadroid grabs Ben, but Xylene frees him. Gwen pushes the Mechadroid away on a forklift. Xylene frees Max and crushes it with a crate, but it merges with the tank that was in the crate and regains control of Max. Xylene tells Ben to destroy the original Mechadroid, unlocks a new alien form in the Omnitrix for Ben and he transforms into Perk Upchuck. She tells Upchuck to eat the Mechadroid and tells him his new alien's power is to eat. Upchuck leaps onto the Mechadroid and begins to eat parts and, upon Xylene's instruction, spits an energy ball. Upchuck continues to eat the Mechadroid as Xylene frees Max. Upchuck eats the original Mechadroid and it deactivates. Upchuck reverts back into Ben who burps out some remaining parts of the Mechadroid.

At the Rustbucket, Ben apologizes to Xylene for his attitude and that if she makes Max happy, then she makes Ben happy. Xylene admits he's more like Max than she thought and gets Ben to promise to look after the Omnitrix as others will come for it. When it comes time to say goodbyes, Xylene knows that Max won't come with her and Max agrees, saying that Ben and Gwen are his whole world and that he will stay for them. Xylene kisses him before she leaves on her ship but not before Xylene states they would always have Roswell. Almost immediately, Ben and Gwen begin to argue while Max looks fondly to the stars.
