Triple Changers (Triplebots for Autobots and Tripletrons for Decepticons in Japan) are Transformers that can transform from robot into two different alternative modes.

Triple Changers were introduced into the Transformers toy line in 1985. They were named among the top selling toys in 1985 by Playthings magazine.

No particular origin was given to the Triple Changers in most storylines. According to the Dreamwave Productions comic, The Triple Changers were the result of experiments by Shockwave to produce a robot with more than one alternate mode. Failed attempts resulted in the Duocons. The first successful Triple Changer was Springer, followed by Blitzwing. Later, they were joined by Astrotrain, Broadside, Sandstorm and Octane. Triple Changers can change between their multiple alternate modes twice as fast as most Transformers.

The original commercial for Scorponok described him as a Triple Changer, despite it not being mentioned on the box. Dreamwave's More Than Meets The Eye series additionally described the Headmaster Horrorcons Apeface and Snapdragon as Triple Changers. In 2005, an E-hobby repaint of Blitzwing named Overcharge was released, making him another Triple Changer by default.
