GHC Heavyweight Championship
In 2003, Suzuki and Yusuke Fuke announced their plan to return to puroresu and invade promotions under the stable name Pancrase Mission. Suzuki began competing for NJPW as a freelancer, where he aligned himself with Yoshihiro Takayama and won the IWGP Tag Team Championship from Hiroyoshi Tenzan and Osamu Nishimura on February 1, 2004. They were stripped of the title later in the year, following Takayama's mounting injuries. In 2005, Suzuki began competing in Pro Wrestling Noah, and would receive a GHC Heavyweight Championship shot against then Champion Kenta Kobashi, but he was defeated. After this, he found an unlikely ally in Naomichi Marufuji, whose style was Lucha Libre (rather than shoot-style). Nonetheless, Suzuki taught Marufuji some of what he knew and they clicked, winning the GHC Tag Team Championship from 2 Cold Scorpio and Doug Williams on June 18, 2005. After losing the belts to Muhammad Yone and Takeshi Morishima in October, Suzuki challenged for the GHC Heavyweight Championship shot against champion Jun Akiyama on March 5, 2006, but he was once again unsuccessful.
