Jimmy Jones

James "Jimmy" Jones is a kid who is a major fan of Ben and his alien heroes. He runs a website with pictures of aliens around the world including, every alien Ben has ever turned into, even dating back to when Ben was ten years old. He always refers to Ben as Mr. Tennyson.

Jimmy wears a hoodie similar in design to Ben's jacket. Jimmy sent out a video that finally showed the world that Ben has the ability to turn into aliens, as he thought Ben would like the fame and money.

Ultimate Alien
Jimmy first appears in Fame when Ben finds out that Jimmy has been posting things and a video about him and his aliens on a website. The team realize that Jimmy is pretty useful so they let him do what he wants.

In Andreas' Fault, Jimmy told Ben about the Forever Knights and where they can go to find the castle.

In Eye of the Beholder, Jimmy gave Ben "relationship-advice".

In The Big Story, Jimmy was trying to get some footage of an alien ship but instead finds a plant alien trying to take over Earth. Jimmy was able defeat the plant and plant copies of Ben, Gwen and Kevin using peanuts which proved to be the plants only weakness.

In The Ultimate Enemy: Part 1, Jimmy and his mother are transformed into Esoterica.
