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.
2005 LEGO Sets
2005 shaped up to be a significant year for LEGO collections. Starting with the fact that LEGO System celebrated its 50th anniversary, we also saw a LEGO set designers change their techniques in set designing. 2006 marked the year that the skin color of the Star Wars minifigures changed from yellow to light nougat which also continued to various other future licensed themes. While this was a simple change, the value of sets saw high growth. 2006 introduced the LEGO City theme which replaced the Town theme, as well as Tiny Turbos under the Racers theme. However, in 2006 LEGO did discontinue Alpha Team and Baby.
