Online Pro Wrestling: The Champion of the Network (2004) was a Japan-only PS2 title that embraced the growing trend of online play. Featuring a roster of fictional wrestlers, it allowed players to compete in ranked matches and tournaments over the internet, a novelty for wrestling games at the time.

Gameplay leaned on timing-based grappling, similar to Fire Pro and King of Colosseum, though with less depth. The focus was on connectivity and competition rather than single-player content. While servers were short-lived, the game is remembered as an early attempt to bring wrestling online, paving the way for future multiplayer-focused titles.
