獣神サンダー・ライガー
Barr made his New Japan Pro-Wrestling debut as "American Machine" in Summer 1994, wrestling under an old American Love Machine mask. He made his debut by teaming with Black Cat and Black Tiger II in a winning effort against the team of Shinjiro Otani, El Samurai and Jushin Liger. Liger apparently had big plans to feud with Barr, but they never materialized after Liger broke his ankle. A match was planned for January 4, 1995 at the Tokyo Dome for the IWGP Junior Heavyweight Championship, but again this never materialised due to Barr's death in November 1994.
