  • Kenny Tennyson Jr. gets his own omnitrix, but is he responsible enough? The RETURN and REVENGE of Kevin 11,000!

    A very special episode and is somewhat similar to the episode "Kevin 11". Both the Heroes (Ben/Ken) get angry with an elder (Grandpa Max/Ben 10,000), go out of their home/RV, for playing games/a little hoverboarding, where they meet Kevin/Devlin, but they soon learn of their powers of absorbing energy/turning into the monstrous DEVLIN 11, and they decide to absorb the powers of the omnitrix/to help his father KEVIN 11,000 return. The only difference is, when Ben offers Kevin to join him, Kevin attacks him, but when Kenny offers Devlin to join him, he eventually joins them, & he kis the one who defeats Kevin. Despite of the similarities, this episode is Superb.moreless

  • good episode

    In the future, Ben's son Ken is celebrating his tenth birthday, and to commemorate the occasion Ben gives him an Omnitrix of his very own. However, he equips it with a limiter, unwilling to trust his son to defeat villains on his own. Ken soon befriends a boy named Devlin, and the same night Kevin 11 attacks. Unable to locate the Null Void, which Ben has moved after the events of "Ben 10,000", he retreats. Ken, also unaware of the move, endeavors to find it on his own, only to unwittingly lead Devlin, who is Kevin's son and can transform into his father's mutant form, right to it. Devlin releases his father from the void, but is soon heartbroken to learn that Kevin's only interest is in fighting Ben, not in seeing his son. Kevin is ultimately defeated by the combined forces of Ben, Ken, and Devlin, who is later adopted into the Tennyson family.moreless

But, this is a awesome birthday because Kenny gets his own Omnitrix!!! But the Omnitrix only has 10 aliens and times out, nomaster contol for Kenny. Ben10K is too overprotective of his son and Kenny gets ticked. He runs of and meets Devin, who happens to be Kevin 11's son! Devin gets Kevin out od the Null Void only to find his dad doesn't want anything to do with him. Kevin hurts Kenny and Ben goes Way Big to squash him like a bug. Devin helps put his dad back in the Null Void and gets adopted by Ben10K.

Trivia, Notes, Quotes and Allusions


  • TRIVIA (23)

    • This episode actually happens in alternate future since it is not canon and it also not coincide with the events in Alien Force. Ben will probably marry Julie Yamamoto instead of Kai and it can be assumed that Kevin becomes a superhero alongside Ben and Gwen instead of villain.

    • Look Closely: On the pop-up trivia version of this episode it says that Ben married Kai and they had two kids, Ken and his sister. If you remember all the children at his party, there is one that looks similar to Kai and could be Ken's sister.

    • Look Hard: When the Omnitrix flashes red when Ken/XLR8 is stuck in the goop, the flash comes from his lower body instead of the Omnitrix's symbol.

    • Think Back: The part when Kevin throws Four Arms and later there's a cloud of dust then Ben turns into Diamond Head and gets shattered is similar to what happened in "Secrets," but instead Vilgax throws, and the only reason he turned into Diamond Head was because of an Omnitix power surge.

    • How come when Ben wants to put aliens in the null-void, he reverts to his human form, but in the fight with Devlin, he was still XLR8?

    • Look Hard: Near the end of the episode Ken was holding a null-void egg. When Kevin took the egg away using XLR8 speed, the trail behind him was blue and black when it should have been black and white.

    • When the Omnitrix timed out with Ken, it should have been a green flash. Because he had something similar to the master control, and the flash was green with Ben too.

    • Ken says he deactivated the limiter in his Omnitrix and says he could switch forms at will. Isn't he supposed to have the master control instead? The only way Ken would be able to turn into other aliens without the master control is if he touched the Omnitrix's symbol.

    • Once more, Heat Blast has no dialogue in this episode.

    • Cannonbolt's face isn't seen in the episode.

    • When Ben mentioned Snakepit and Sandbox, it gives you a hint of what they might look like. Snakepit being a snake alien and Sandbox being a sand alien.

    • Look Closely: When the intruder alarm goes off at first, Ben's pajama sleeve is intact, but when Devlin shows (impersonating Kevin 11), Ben's sleeve is ripped.

    • Some of Kevin 11,000's alien parts resemble Ben's adult alien forms (like the Heat Blast shoulder and Four Arms arm), but some other parts look the same as young Ben's (the XLR8 tentacle has blue stripes, and the Wildmutt arms still have quills).

    • Way Big's upper lip is white in this episode, instead of the black color that it was in Ben 10: Secret of the Omnitrix.

    • Devlin's mom (Kevin's wife) isn't mentioned. Ironically, wouldn't Devlin be with his family inside the Null Void?

    • Look Closely: When Way Big says, "How dare you!" he has rather long ears, but when he begins to punch at Kevin, the ears are gone.

    • There are eleven candles on Kenny's birthday cake, not ten. Either this was a drawing error, foreshadowing Kevin 11,000's appearance in the episode, or just one to grow on.

    • Look Closely: The tattoo on Kevin 11,000's chin changes from red to brown.

    • Everyone seems to have changed in appearance since "Ben 10,000." Gwen and Grandpa Max have different figures. But considering this is about 12 years from when present Ben probably came along, that could make sense.

    • Ken's mom is not mentioned or featured, nor is her absence mentioned or questioned. Though it's possible for Kai to be Ken's mother because of his darker skin.

    • After Ken deactivates the limiter, the Omnitrix still times out, because he was too weak to fight.

    • It's never explained fully how Kevin and Devlin can change between their human and mutant forms.

    • In "Ben 10,000", Max had the same body type as he does in the present, but in this episode he is very thin.

  • QUOTES (10)

    • Ken: (Ben turns into Benmummy, who has a straight face and helps Ken get out of an air vent) Don't look at me like that!

    • Ken: (is Buzzshock and electrocuted an enemy, but Ben finished him off) Dad, I had him!

    • (Ben sees Ken weak and on the ground and supposes that he is hurt badly, so he turns into Way Big)
      Way Big: How dare you!!!! (starts punching Kevin like crazy)

    • Ben 10,000/Four Arms: (about Vulkanus) I do not have time for this. I'm not gonna miss another one of his birthdays, so I'd appreciate it if you just chill out in the Null-Void. (reverts to his human form and sends Vulkanus to Null-Void)
      Ben 10,000: Some scum just can't take a hint. (turns into XLR8)
      (XLR8 runs to his HQ and reverts to his human form)
      Ben 10.000: Told you I wouldn't miss your birthday.
      (Ken sees him and hugs him)
      Ken: Thanks, Dad.
      Ben 10,000: You only turn ten once.
      Ken's Friends: Happy birthday, Kenny!

    • Devlin: Dad, stop, you've proved you're the best.
      Kevin 11,000: You think I have something to prove? (throws Devlin) I already know I'm the best! I'm doing this because I like it!!!

    • Gwendolyn: Kenneth Tennyson.
      Kenny: Aunt Gwendolyn!
      Ben 10,000: Actually, she's your first doofus cousin, once removed.
      Gwendolyn: Will you EVER grow up?

    • Kevin: I suppose I should thank you. With all that time I spent in the Null Void, I was able to absorb a few tricks from all the aliens you locked in there with me. (transforms into his mutant form) Ben 10,000, meet Kevin 11,000!

    • Four Arms: (finding Kenny and Max tied up) Not much of a trap. Or was I supposed to think my family tied themselves up?
      Kevin: Oh, Ben. You always were too smart for me. Or was that the other way around?

    • Kenny: It's our danger alert. The call comes in, and my dad takes off to, you know, save the world!
      Kid: Wow! My dad's just a boring old dentist!

    • Kenny: (referring to Max's Hoverboard gift) At least I got one present that isn't completely useless.
      (Kenny's pet stone puppy stares on dejected, but Kenny doesn't notice)
      Ben 10,000: Where does he get that attitude from?

  • NOTES (42)


    • Kevin 11

      This episode is very similar to the episode "Kevin 11." Both the heroes (Ben/Ken) get angry with an elder (Grandpa Max/Ben 10,000), go out of their home/RV, for playing games/a little hoverboarding, where they meet Kevin/Devlin, but they soon learn of their powers of absorbing energy/turning into the monstrous DEVLIN 11, and they decide to absorb the powers of the Omnitrix/to help his father KEVIN 11,000 return. The only difference is, when Ben offers Kevin to join him, Kevin attacks him, but when Kenny offers Devlin to join him, he eventually joins them.

    • The Emergency Alarm
      Ben 10,000's alarm system is very similar to the one used by the Teen Titans in their tower. Which makes sense, since Ben's future headquarters is very similar to Titans Tower.

    • Kevin 11,000: Appearance
      Continuing the Naruto references, Kevin 11,000's appearance is similar to Orochimaru, one of the shows major antagonists. He also bears a resemblance to The Riddler in The Batman (sans the mask).

    • The Null-Void Traps: Pokeballs
      The ball-shaped traps Ben 10k uses to trap his enemies are similar to the Pokeballs from Pokemon.

    • Ben 10,000: Sideburns
      Ben, now at least 40 years old, is sporting sideburns that are white, much like Reed Richards of the Fantastic Four.

    • Johnny Quest
      The Tennyson family by the end of this episode is a lot like the Quest family of Johnny Quest fame. There's a scientist (Max/Dr. Quest), a muscular guy (Ben 10,000/Race Bannon), the son (Ken/Johnny), the adopted son (Devlin/Hagi), the strong independent young woman (Gwen/Jessie) and the dog (the golem thing/Bandit).

    • Devlin: Hairstyle
      Devlin's hairstyle is very similar to that of Duke Devlin from Yu-Gi-Oh!

    • Devlin: Appearance
      Devlin's appearance in human form is very reminiscent of Sasuke Uchiha's of Naruto fame. Note the hairstyle and the wrappings around one of his legs.

    • Billy: Cameo
      The alien Ken is talking to in the beginning of the episode, who responds to Ken's story with 'Wow! My dad's just a dentist,' is modeled closely after Billy from The Grim Adventures of Billy and Mandy, right down to the clothes, massive nose, and even voice actor, Richard Horvitz.
