Answer
The answer is Giant Bernard. In 2006, Anderson and Bernard formed a tag team called the "Bad Intentions" and quickly rose through the ranks of NJPW. They captured the IWGP Tag Team Championship in January 2007, defeating Hiroshi Tanahashi and Yutaka Yoshie. This marked Anderson's first reign as IWGP Tag Team Champion and his first reign with any championship in NJPW.
