===Video Games===
====Sumo Slammer Smackdown====
Sumo Slammer Smackdown is a video game in which the sumo samurai protagonist, Ishiyama, fights and battles against the shape-shifter Kenko, his arch-enemy. It is one of Ben's favorite games, and is also liked by Gwen and Max. It contains at least 13 levels, featuring Robo-Sumos and Samurai as standard villains with boss variants. Players can access weapons by discovering them hidden inside 'Akeni' boxes and fight their way across levels. Solving a riddle by Kappa allows players to jump to any level of their choosing. Like any video game, the "main boss" fight (in this case with Kenko on level 13) is the hardest level.Game Over
In Game Over, Ben and Gwen wound up in the video game when Ben attempted to use Upgrade to cheat at the game and was struck by lightning whilst playing. To unlock and transforms into his aliens, Ben must collect Omnitrix shaped tokens hidden across the game. He eventually collects Four Arms, Cannonbolt and Upgrade, which he uses to trounce Kenko and escape the game alive. Ben recalled the events of this episode in Ben 10: Destroy All Aliens.

*As of Game Over, Ben owns every Sumo Slammer comic book, doubles of every trading card and even eats a Sumo Slammer themed cereal.
*The company purposely includes one bad episode every season to boost interest, so people can buy the toys.Jimmy JonesAndreas' Fault
*The popularity of Ben's aliens with kids made Sumo Slammers less popular by the end of the summer in the original series.
*Kevin is more interested in the games and movies compared to the TV show.The Final Battle: Part 1 Meanwhile, Gwen was interested in Sumo Slammers during the original series. However, she has lost interest by Alien Force.Voided
*The Dimension 23 counterpart of Sumo Slammers is known as Judo Jammers.Ben 23It's a Mad, Mad, Mad Ben World: Part 1
*Sumo Slammers is often used as a meta-reference to the Ben 10 franchise.
**Sumo Slammers: Hero Generation is a direct parallel to Alien Force.
***It takes places 5 years after the original Sumo Slammers series, just like Alien Force.
***Kenko, the villain from the original series teams up with the hero, Ishiyama, just like Kevin and Ben team up.
***Ben mentions how Hero Generation was all messed up and whatnot, a meta-joke on how Alien Force wasn't as popular as the original. Adding to it, Kevin expresses disgust towards the show and Ben opines that it is not as good as the classic, a reference to Ben 10.
***Ben also mentions that in five episodes, it would switch to the original. This is a meta-reference to the change in the writing of the second season of Alien Force to make Ben's personality and the overall storyline mirror the original series.
***Moreover, Hero Generation was the original working name for Alien Force.
**The catchphrase, "It's slammer time!", spoken by the audience in Sumo Slammers IV, is a parody of Ben's catchphrase, "It's hero time!".Duped
*There is a real toy line based on the Sumo Slammers.
*In the online game FusionFall, several other characters like Sumo Slammers such as Bloo (from Fosters Home for Imaginary Friends) and Mandark (from Dexter's Laboratory).
**Oddly enough, both of them mentioned Sumo Slammers during Nano Missions. For example, Bloo needs his Juice box back so he can play Sumo Slammers online and beat "Omnitrixter". Meanwhile, Mandark wanted to find out who "Omnitrixter" is.
