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.
2004 LEGO Sets
2004 was a shakeup year at LEGO, coming off of 2003 with record losses. Some significant events include the release of the QUATRO System for very young children, and most notably the replacement of many long-standing LEGO colors including gray, dark gray, brown and violet and the introduction of some new colors like light nougat which ultimately became the skin tone for many minifigures. In 2004, The LEGO Group created a partnership with Ferrari and a number of LEGO Ferrari sets were released that year based on Ferrari’s Formula 1 racing cars. New themes released in 2004 included Maersk, Knight's Kingdom II and Ferrari under the Racers theme. LEGO discontinued the Adventurers Orient Expedition, the original Spider-Man theme, LEGO World City and Gravity Games.
