Lion Knights is the name collectors use for the knights with the lion crest, one of the first Castle factions of 1984. LEGO did not give them an official name for years, and catalogues called them Lion Knights in the United States and Australia and Lion Crest in Canada.
1987 LEGO Sets
1987 reshaped core worlds: Futuron and Blacktron established a new Space rivalry, and the Forestmen arrived in Castle with woodland hideouts and outlaw flair. Early computer-control experiments appeared in the Technic ecosystem, foreshadowing later programmable systems. Across the portfolio, factions and clearer narratives became a defining design focus.
