A toy line manufactured by Bandai was originally shown off at Toy Fairs around the world. A possible unintentional leak of official images of the line was released on the website of department store Kmart. Figures that were revealed at Toy Fairs such as Bloxx,[38] Shocksquatch,[39] 16-year-old Ben Tennyson,[40] an 11-year-old version of Ben,[41] and Ben's sidekick Rook[42] were listed on the website. The vehicle play set, "Rook's Truck", has won an award for Best Action Figures/Accessories at the 2012 London Toy Fair.[43] The Omnitrix Touch has a gray color instead of the white it features in the show.

A video game of the same name is developed by Vicious Cycle Studios for the Wii U, Wii, PlayStation 3, Xbox 360 and by 1st Playable Productions for the Nintendo 3DS and Nintendo DS.[44] The action beat 'em up features 15 playable characters on DS and 3DS and 16 playable characters on the other systems. It also features a two-player co-op play.[44] The game follows Ben and Rook in a battle to defeat a fierce villain, named Malware, who has evil plans of destroying the world.[44]

Omniverse also spawned a second video game, which was developed by High Voltage Software for the Wii U, Wii, PlayStation 3, and Xbox 360 and by 1st Playable Productions for the Nintendo 3DS.[45] This game takes place during the events of Frogs of War, where Ben must fight the Incurseans to get back to Earth and stop Emperor Milleous, Attea, Dr. Psychobos, and the Way Bads.
