The series centers on Ben Tennyson, a 10-year-old boy on a summer vacation road trip with his cousin Gwen and their grandfather Max, who is secretly a member of an intergalactic organization called the Plumbers. On their first night camping in their grandfather’s RV, nicknamed the Rust Bucket, Ben finds a mysterious watch-like alien device which sticks itself upon his wrist, giving him the ability to transform into several (initially ten but later more) alien life-forms, each with special abilities. During their vacation, the Tennysons are attacked by various enemies, ranging from aliens such as intergalactic warlord Vilgax, bounty hunter duo Sixsix and Kraab, Ectonurite high king Zs’skayr, an 11-year-old delinquent named Kevin Levin who has the ability to absorb energy, mad scientist Doctor Animo, mysterious paramilitary organization the Forever Knights, supernatural entities such as interdimensional sorcerer Hex and his niece Charmcaster, and clown mastermind Zombozo and his Circus Freak Trio.
