The LEGO Technic Supplementary theme, active from 1977 to 1997, consists of a variety of accessory sets designed to enhance and expand existing Technic models. These sets provided additional parts, such as gears, wheels, axles, and motors, allowing builders to add more functionality and complexity to their creations. Notable sets in this theme include the "870 Technical Motor," which introduced a battery-powered motor for motorizing models, and the "8710 Supplementary Set," a collection of gears and other essential mechanical parts.
1997 LEGO Sets
1997 saw LEGO’s first major sales decline, prompting experimentation and digital expansion. LEGO Island introduced the brand’s first open-world video game, setting the stage for future digital storytelling. New subthemes included Divers for underwater exploration, Fright Knights for gothic medieval fantasy, and Time Twisters as a sequel to Time Cruisers. LEGO Space added Roboforce and UFO, shifting toward alien-focused designs, while Aquazone expanded with Aquaraiders. Despite challenges, LEGO’s creativity remained strong across both physical and emerging digital platforms.
