Lego Bionicle has been a smash hit since its introduction in 1999, and represents the first time that Lego have created a series based on a storyline of their own creation. The Bionicle sets are based in a world inhabited mostly by biomechanical creatures, who wage war on the island of Mata Nui, and permits children to fight with the Toa Mata as they protect the Matoran from the villainous Teridax. The Lego Bionicle series is perfect for young boys, and the Toy Industry Association named it Best Boy Toy of the Year and Most Cutting edge Toy in 2001.

The designs for the Lego Bionicle models is a fusion of conventional Lego designs and more advanced sets like Lego Technic.  As with many Lego series the models vary in size and difficulty so that you can find something that perfectly fits one's interest or capability.  Many of the models feature movable parts, and you can even combine them with Technic pieces like motors to make advanced custom models.

Mata Nui is a tropical island from traditional times, and it is living in fear of the noxious spirit Makuta. Six brave warriors know as the Toa must protect the island and its inhabitants from this malignant force. The Toa must find their masks of power to destory the Makuta, and the noxious Bohrok swarms that come after them. Even the residents of the island must arm themselves and join in the battle. The Lego Bionicle world forms a stimulating storyline for youngsters to take part in, and there are regular new releases that will sustain interest and add new twists to the tale. There are even Lego Bionicle film and computer game tie-ins that will allow kids to get even more involved in the story.

Some of the most well liked Lego Bionicle sets include the Toa Lhikan and Kikanalo Set, in which Toa Lihikan rides on one of the great beasts of Mata Nui, the Muaka and Kane-Ra featuring snapping jaws and adjustable claws, and the Bionicle Jetrax T6 which features retractable turbines, ball-firing jet blasters, and a cockpit which can seat Lego Bionicle figures.

All of the Lego Bionicle models are great fun to build, robust to play with, and feature a battle-against-evil story that will keep kids and teens entertained and excited for a long time.
