Mission Deep Freeze is an Alpha Team subtheme, that ran from 2004-2005. The theme centers around a team of secret agents known as the Alpha Team, and their efforts to stop the nefarious villain Ogel from taking over the world. In 2004, LEGO revised Alpha Team with a new logo, updated character appearances, and replaced Cam and Crunch with Agents Arrow and Diamond Tooth. Vehicles gained an "Alpha Mode" feature for transformation without disassembly and a new color scheme of black, gray, white, sand blue, and transparent colors for details.
