Ben 10: Omniverse

Ben 10: Omniverse is the fourth iteration of the Ben 10 franchise, and it is the sequel of Ben 10: Ultimate Alien.

Summary
Ben was all set to be a solo hero with his new Omnitrix after Gwen and Kevin left for college, but Grandpa Max teamed him up with a rookie, by-the-book partner. Together they explore a secret alien city, known as Undertown beneath the city of Bellwood. Meanwhile, a mysterious hunter, known as Khyber, sets his sights on Ben! With all new alien heroes to choose from, the fun is just getting started. It's a whole new Omniverse!

Lyrics
Ben 10!

He's a kid and he wants to have fun

But when you need a superhero, he gets the job done!

Ben 10!

With the device that he wears on his arm, he can change his shape and save the world from harm!

When trouble's taking place, he gets right in its face!

Ben 10!

When lives are on the line, it's hero time!

Ben 10!

Errors

 * In opening 1 and 2, 11 year old Wildmutt has two Omnitrix symbols.
 * In opening 2, the wrong Omnitrix symbol disappears, but Wildmutt has 2 braces yet.
 * In opening 3, NRG's foot is under Crashhopper's.

Trivia

 * Starting with Ben Again (US Airing Order) and T.G.I.S. (Production Order) for Arc 3, new sound effects were added to the opening. These include the Omnitrix's activation sound and Upchuck, Crashhopper and Rath's sounds.
 * Derrick J. Wyatt confirmed that the opening will be changed in some way to add new aliens.
 * Starting with Evil's Encore (US Airing Order) and Food Around the Corner (Production Order) for Arc 4, the opening changed.
 * In the UK, the opening is different than the USA one.
 * Starting with Something Zombozo This Way Comes (US Airing Order/Production Order) for Arc 5, the opening has been changed for the second time.
 * In Clyde Five, the opening was focused on Clyde Fife.
 * Starting with Rook Tales for Arc 7, the opening gets an electric note in the background during the song.

Trivia

 * The head of the art department is Derrick J. Wyatt, who was also in charge of the art for Transformers Animated, Scooby Doo Mystery Incorporated, and Teen Titans.
 * According to Derrick J. Wyatt, the flashbacks happened during weekend trips.
