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 completely revised Alpha Team. The theme's logo was changed, many of the characters had different appearances than in previous years and some characetrs such as Cam and Crunch were removed and replaced with Agents Arrow and Diamond Tooth. Alpha Team vehicles were given a new feature, known as Alpha Mode, which allowed them to be transformed into another vehicle without disassembling them. In addition, The Alpha Team vehicles' color scheme were completley changed, featuring black, grays, white, and sand blue, as well as various transparent colors for smaller 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.
