Ever since "Ben 10" came out in 2008, gamers have wanted to play a "Ben 10" online game. The story goes something like this. Ben was a normal ten-year-old boy who ends up obtaining a watch that allows him to turn into various aliens whose DNA has been encoded into the watch. Ben uses the watch to transform into those ten different aliens who have varying powers and weaknesses. The idea behind the watch is effectively used in online games on the internet.
- "Ben 10 Ultimate Alien Challenge" In this game, you play as Ben and use the various characters and aliens in order to solve problems.

Then again, Cartoon Network has the money to back a game like this.
- "Ben 10 Power Splash" This game is a side scrolling game where you swim through various levels, fighting the enemies that get in your way. The controls are simple enough.
