The people on the island are controlled by an evil beast called Makuta, and the Bionicles are the heroes who have sworn to protect them and give them back their freedom.
The robot figures have different masks which you can change around.
Predictions for 2002
A candyfloss maker was named the craft of the year and the craze of the year was a pogo stick.
A new doll whose features can be painted on by her owner won the best girls' toy.
The Toy of the Year was named as part of a five-day toy fair, where the predictions for the top toys of 2002 were released.
We sent a Press Packer along to the toy fair.
