Jinsei Shinzaki
Even though Battlarts' style was based on shoot wrestling, the promotion often cooperated with other federations and styles, including RINGS, Kingdom, Michinoku Pro and Big Japan Pro Wrestling. The biggest co-promotion occurred on October 17, 1999 when Battlarts and The Great Sasuke's Michinoku Pro Wrestling presented "Michinoku Pro vs. Battlarts", which was headlined by a tag match pitting the owners of both promotions (Great Sasuke and Ishikawa) against Jinsei Shinzaki and Alexander Otsuka.
