獣神サンダー・ライガー
Yamada as "Jushin Liger" returned to NJPW on April 24, 1989, at the Tokyo Dome. In the character's debut match, he defeated Kuniaki Kobayashi at Battle Satellite in Tokyo Dome. He has also wrestled all the Black Tigers to date (from Mark Rocco in 1989 to Tatsuhito Takaiwa in 2009). The Liger character underwent changes in conjunction with the Go Nagai anime progressing and its hero powering up. In January 1990, Liger was renamed "Jushin Thunder Liger", a name he continues to use to this day. Early in his career, Yamada's style mostly consisted of high flying. Years later, he started adapting more power moves and started focusing more on grappling and telling a story in the ring; part of this change was due to the fact that Liger had to reduce the stress he was putting on his body after undergoing brain tumor surgery in August 1996, which explained why he lost his match to Último Dragón in the first round of the J-Crown tournament.
