1992 saw the formal launch of LEGO Dacta, later LEGO Education, integrating bricks into classroom learning. DUPLO introduced the Toolo subtheme, using toy screwdrivers and bolts for mechanical exploration. In Castle, the Wolfpack faction debuted, representing outlaw knights, while Space Police II modernized the LEGO Space law enforcement narrative with updated designs and continuity from Blacktron II. LEGO also expanded into Asia with the founding of LEGO Japan, solidifying its growing international reach.
