Autobots and Decepticons are mechanical aliens who can transform between large bipedal robots and vehicles. The movies and the costumes are very popular among boys of all ages. The Transformers series of movies, and the toys and old television show they're based on, tell the story of the million year war between the Autobots and Decepticons. The movies take place on Earth, where these two factions, along with help from military and civilian humans, battle it out for domination.
The leader of the Autobots, and one of the more popular Transformers costumes, is Optimus Prime. He's a red and blue robot who turns into a big rig truck. He fights for freedom and equality for all. His oldest friend is the Autobot, Ironhide. He is metallic gray and can transform into a large pickup truck. He's old but a skilled warrior and the Autobot team's weapons specialist. One of the most popular Autobots is Bumblebee, the yellow and black robot who turns into a Camero. He is a scout for the team as well as the bodyguard for the main character, Sam. Bumblebee is a favorite among kids because he often comes across as childlike, himself.
