Lego and Cartoon Network collaborated to make a line of LEGO toys for Ben 10: Alien Force.They came out in 2009. A total of six of them were released: Swampfire, Humungousaur, Spidermonkey,Chromastone,Jetray, and Big Chill.

They only lasted one wave before they were discontinued.

Assembling ThemEdit

The pieces of the figures connect when compatible connectors are snapped into their appropriate sockets. In this way, a complete model can be created, along with a vast number of other combinations.  The pieces are compatible with other LEGO products, especially those which also use the ball-and-socket system.  The figures also glow in the dark.
