First Appearance Ken 10

Kenneth "Kenny" Tennyson also known as Spanner is the son of Ben Tennyson and Kai Green. On his tenth birthday, he received a duplicate Omnitrix from his father. He made his first appearance in Ken 10.


Kenny bears a striking resemblance to his father when he was his age. His clothes are modeled after his father's. These include a white t-shirt with black accents and borders at the sleeves, and his trademark baggy green cargo pants. Kenny's eye color is even the same as Ben's. But his skin tone is slightly tanned which he inherited from Kai.

Spanner full body


In Omniverse, he is a bit older and the black and white on his shirt is now switched. The cuffs near his leg as well as his belt is now green and he has black pockets instead of white. The circle around his belt buckle is now white. His eyes are a darker color.

As Spanner, he wears a white armored jumpsuit, along with a green scarf and a white helmet. He appears to have some-sort of equipment on his wrists.


Kenny is very much like his father was when he was 10 years old. One example of this was his immediate friendship with fellow troublemaker Devlin Levin. Like Ben, Ken had access to only 10 alien forms in the beginning with his Omnitrix, but he later gained access to more. He was also shown to be slightly more resourceful than his father as he used Grey Matter to hack the Omnitrix and unlock the Master Control.


Ben 10


In Something Zombozo This Way Comes, he appeared as a mysterious white suited hero and protected Ben from getting hit with a shoe from one of the Zombie Clowns. However, by the time Ben could turn around to see who was behind him, he vanished in a green light.

In Animo Crackers, Kenny appears again as Spanner and attacked Dr. Animo, along with Animo's future self, revealing his alias. When Ben arrived, the Animos split up, and Spanner immediately pursued the future Animo. Both he and Ben were subdued by this Animo. Spanner then instructed Ben to contact Lieutenant Steel, which led Ben to discovering that Steel's group was under attack. Ben, Rook, and Spanner arrived at the scene, Ben using Gutrot to defeat the Animos. Spanner then teleported away with the future Animo, and Ben wondered who he was.

In Cough It Up, Spanner appears frequently to aid Ben and Rook while they defend Argit. Because he and Jimmy Jones, who also appears in the episode, never appear at the same time (and he also seems to be a fan of Jimmy), Ben and Rook believe that Jimmy is, in fact, Spanner, though he states he doesn't even know who Spanner is.

In Fight at the Museum, he revealed himself to be from the future, where Ben and Kai are married. While trying to save the first alien artifact that Kai and her grandfather found together, he tries to make sure Ben and Kai end up together at all costs. Knowing that it's for the greater good, Spanner steals the emptied artifact and returns to the future where he sees that Ben and Kai are still married.

In The End of an Era, Spanner assisted Ben 10,000 in battling Maltruant, before revealing himself to in fact be his son Kenny, who wanted to prove himself to be a true hero after Ben took away his Omnitrix, and was given a device by Professor Paradox that would allow him to travel through time.

Powers and Abilities

Kenny wears an Omnitrix made by his father on his left wrist. His list of aliens are:


He possesses a technologically advanced, full-body suit (provided by Professor Paradox) that is armed with wrist-mounted blasters and jet-boots, which allow him to fly. He possesses an object, that allows him to travel through time.
