LEGO BIONICLE Accessory sets weren't standalone sets in the traditional sense, but rather supplementary products that complemented the main BIONICLE sets and themes. These accessories added depth to the Bionicle universe and allowed fans to customize and interact with their Bionicle figures in unique ways.
2007 LEGO Sets
For collectors, 2007 proved to be an important milestone for with the release of the Modular Buildings theme which initially included Café Corner (10182-1) and Market Street (10190-1). Also, the Star Wars license with LucasFilms was originally planned to end that year, but is renewed. To celebrate Star Wars' 30th anniversary, LEGO released a free, 14-carat gold C-3PO minifigure. 2007 also saw the discontinuation of a number of themes including Aqua Raiders and Knights' Kingdom II but also so the introduction of the Thomas and Friends theme.
