Bionicle
LEGO's buildable biomechanical warriors, sold in collectible canisters and wrapped in a sprawling island mythology kids argued about at recess. Part toy, part epic saga — you built the heroes, collected their masks, and followed the lore across comics, books, and films.
Bionicle launched in 2001 (after a late-2000 test run), growing out of LEGO's earlier Slizer/Throwbots line. Instead of stacking bricks, you assembled poseable, ball-jointed figures — the heroic Toa and the villager Matoran — and collected the Kanohi masks that gave them powers, snapping in disc and Zamor-sphere launchers along the way.
What made it more than a toy was the story. LEGO built an elaborate mythology around the island of Mata Nui, the Great Spirit, and the villain Makuta, and told it across comic books, novels, four direct-to-video films, and video games, with writer Greg Farshtey scripting most of the comics and books. Kids collected, traded, and fiercely debated canon. First-year sales brought in £100 million, it won Toy of the Year for innovation in 2001, and it became a major contributor to LEGO's recovery from its late-1990s financial troubles.
The launch wasn't without controversy — LEGO drew criticism for trademarking Māori words and renamed the "Tohunga" villagers to Matoran after reaching an agreement. The original line ran through 2010, with a brief reboot in 2015–16, but for a generation Bionicle is the great LEGO saga of the 2000s.

K'NEX
A construction toy of colorful plastic rods and connectors that snapped together to build structures, vehicles, and elaborate motorized contraptions like Ferris wheels and roller coasters. Invented by Joel Glickman and launched in 1992, K'NEX was the rods-and-connectors alternative to LEGO's bricks, and it rewarded imagination and structural thinking with click-satisfying mechanical systems.
Beyblades
These spinning-top battle toys from Takara launched a worldwide mania in the early 2000s. You loaded a Beyblade into a rip-cord launcher, shouted "Let it rip!", and battled rivals in plastic arena bowls called Beystadiums. Customizable parts (attack, defense, stamina types) and the anime tie-in made them trading-post essentials.
Bakugan
The spring-loaded battle-toy franchise from Spin Master and Sega Toys (Bakugan Battle Brawlers), tied to an anime series that launched in Japan in 2007 and on Cartoon Network in the U.S. in 2008. The toys were marble-like orbs that popped open into fierce little figures when rolled onto magnetic metal battle cards — a successor to the Pokémon and Beyblade collect-and-battle craze.
Puppy Surprise
"How many puppies?" The plush mother dog with a velcro-sealed belly hiding a litter you couldn't count until you opened her up—three, four, or maybe five. The suspense (and the long odds on getting five) was the whole toy.
