Lei Wu-long's "Comet Kick" is directly inspired by Korean super-kicker Won Jin's technique "Heaven's Knife Whirlwind Kick" from the Hong Kong movie Kit ji jin si (1992). It first appeared as a shot for shot recreation in Lei's ending movie from Tekken Tag Tournament (1999), and then became added to his move list from 鉄拳 Tekken 4 (2001) onward.
