The Eggman Cometh is the twenty-seventh episode of the third season of Ben 10: Ultimate Alien, and the forty-seventh episode overall.


When vicious dragons invade Bellwood, it's up to Ben and an all-new alien named Juryrigg to battle the flying demons and return the peace.[note 1]


Natalie is preparing chocolate chip cookies in her kitchen, following a recipe on the radio. She is interrupted by Gwen, who tells her she is off to Kevin's house and has to borrow her car. After Gwen leaves, Natalie continues cooking when the egg which she took from a carton in the fridge begins to crack open.

When Gwen arrives, she finds Kevin with a Plumber weapon in the middle of a battle with Fasttrack. Just when things are seemingly turning bad, she steps in. The two begin to explain that they were only training to learn Ben's new aliens' abilities when Gwen gets a call from Natalie who says she saw a dragon-like creature in her house. Gwen promises that they'll come and check it out.

Juryrigg's debut

In Kevin's car, Ben sees the "dragon" (actually a pterodactyl) flying through the trees nearby, outside the window, and warns the others. Kevin then changes direction to follow the creature off-road. Ben attempts to transform into Jetray to help them catch up to it, but the car makes a sharp turn, and the hologram shifts before he transforms, transforming him into Juryrigg instead. Juryrigg psychotically begins to tear apart the brakes, causing the car to spin out of control. Kevin picks him up and toss him back into the seat, just before barely stopping the vehicle by absorbing it and breaking through the floor using his feet.

Clockwork viewing the past with his abilities

In Gwen's kitchen, Natalie explains that the pterodactyl broke through the wall, where there is now a huge hole. The four try to figure out where it came from with Gwen suggesting that Ben should use one of his new aliens to help, but he is still scared from the Juryrigg incident, although he eventually does transform into Clockwork anyway. By viewing the past, they discover the pterodactyl emerged from the egg Natalie was using, which was produced by Animo Farms, where Dr. Animo is raising the same pterodactyls.

Ben, Gwen and Kevin go to see the town's sheriff, who is concentrating on a crossword puzzle. The sheriff states that "on paper, Dr. Animo is a good scientist" and news of pterodactyls getting out would ruin the opening of the new foundry and kicks them out. As the three depart, Ben remembers that his family has a carton of eggs in their house, too.

When they arrive at Ben's house, they find a group of baby pterodactyls having a riot in the living room. Ben transforms into Swampfire, but the cold-blooded creatures tackle and overpower him because of the heat he produces. Gwen begins blasting the pterodactyls off of him with her mana, while Kevin opens the door to their basement, then Gwen uses her mana to shove the pterodactyls in, trapping them. Gwen suggests reporting to the sheriff again, thinking he will listen this time, but Ben decides to investigate Animo Farms instead.

Once the team arrives, they break into a barn after Ben transforms into Humungousaur and discover a secret lab with a machine that Animo uses to put the pterodactyls into the eggs and a computer that has all of his plans. They use it to discover that Animo is planning to sabotage an experiment that is supposed to end global warming (which is going to happen tonight), which would hurt his pterodactyls because they're cold-blooded. They quickly leave, but unknown to them, a pterodactyl (the same one who hatched in the beginning) picks up a phone and alerts Animo.

The weather balloon is destroyed

In the desert near where the weather balloon is going to take off, Animo drives up in a truck that has a missile launcher on it and fires at the balloon. The team drive in and Ben becomes Fasttrack again (as Juryrigg had done some damage to the brakes in Kevin's car because of which they couldn't catch up with Dr. Animo) before racing to stop the missile. Unfortunately, despite giving all of his effort and speed, Fasttrack fails to stop the balloon from being destroyed by the missile, setting the project back months.

At the foundry, more pterodactyls wreak havoc because they want the heat from the melting steel. Ben, Gwen, and Kevin show up (with Ben transforming into Big Chill) and easily stop them by entrapping them in ice. Meanwhile, Animo tells the dragon that he promises to make him ruler when the pterodactyls take over the Earth. The leader says he deserves a name which Animo tries to decide before the team breaks in. Animo uses some of his eggs to hatch more fully-grown pterodactyls that Gwen and Kevin battle, while Ben uses Juryrigg to disable the ray, but again goes on a rampage and tears it to shreds.

Kevin threatening Animo

Meanwhile, after Gwen and Kevin beat the pterodactyls, they threaten Animo to tell them how to reverse the ray's effects. Animo says that changing the polarity of the ray will evolve the pterodactyls into birds, just like the dinosaurs. But Ben had already destroyed the ray as Juryrigg. Luckily, Gwen figures out breaking things isn't Juryrigg's only power and so Ben once again becomes Juryrigg to repair the broken ray and changes its polarity.

Jetray flies around the town with the ray (which was converted into a smaller version with straps) around his chest and evolves all of the pterodactyls to chickens, along with accidentally evolving the Sheriff's intelligence to superhuman levels.

  • The episode's title is a reference to the play The Iceman Cometh.
  • The commercial with Dr. Animo is a parody of the Joker Products scene from Batman.


  • When Natalie is cooking in the kitchen, the bowl she uses to mix ingredients changes size between shots.
  • Melinda stops speaking on the radio once Gwen opens the door to the kitchen.
  • When Gwen talks on the phone, Kevin has six cartridges instead of seven.
  • When Kevin is teasing Ben when he wants to continue their training, when Ben raises his Ultimatrix arm up, the Ultimatrix is overlapping his jacket.
  • In Kevin's car, Ben moves from the left to the right and then to the middle.
  • In one shot, Kevin is not wearing a seatbelt.
  • When Ben scrolls through his aliens before turning into Juryrigg for the first time, the aliens' holograms face away from him. This error occurs again before Ben turns into Fasttrack for the second time, and Juryrigg for the second and third times.
  • Given the floorplan of Gwen's house, it is actually impossible for the kitchen to exist in it. The Pterodactyl can be seen running into the street from the wall to the right of the refrigerator. It can be inferred that the kitchen should be at the front end of the house. However, the window seen is too small to match up with the window seen in exterior shots of the house, and if that were to be the case, the window above the sink would look into the entranceway of the house rather than outside.
  • When Clockwork views the past in Gwen's house, Natalie does not say "What is it, honey?" like in the original scene. Furthermore, her line "Okay, but don't eat any peanut butter sandwiches" is cut, as she just says "sandwiches". Melinda's voice is also not heard from the radio.
  • When the trio leave the police station, they leave the door open, but in the next scene, the door is closed.
  • When the scientist is talking, Ben's jacket stripes are gone.
  • In the old steel mill, before Ben becomes Big Chill, the garage-type door behind him is open, but after he transforms, the door is closed.
  • Before Ben becomes Big Chill, his hologram doesn't appear on the Ultimatrix.
  • When Gwen blasts the wall behind Dr. Animo, the area behind it is shown to be outside, but in the next scene, it is shown to be another room.

XLR8's hologram

  • The episode's title is listed as The Egg Man Cometh on Amazon Prime Video.
  • It is revealed that Ben and Kevin train with Ben's new aliens to find out their powers.
  • XLR8's hologram is briefly seen when Ben is cycling through his aliens.
  • During production, Stan Berkowitz was concerned that higher-ups would have an issue with this episode, as it touts both evolution and global warming as facts.[SB 1]
