Spear master of the imperial guards in 《水浒传》, framed by the official 高俅 after Gao's adopted son set his eye on Lin's wife. His flight to the outlaws is the classic case of 逼上梁山, being driven to revolt.
His breaking point is the chapter 林教头风雪山神庙, 'Instructor Lin at the mountain-god temple in wind and snow': sheltering there, he overhears that the fodder depot he guards was set alight to kill him, kills the men who did it and flees to Liangshan.

His nickname 豹子头, 'Panther Head', fits his looks: the novel gives him 豹头环眼, 'a leopard's head and ringed eyes', the very words 三国演义 uses for 张飞, and he fights with Zhang Fei's weapon, the eighteen-foot serpent spear.
