Fans attending the May 16, episode of TNA iMPACT will more than get their money's worth as they'll be witness to the "biggest" main event in the show's history.

The Champion's Challenge has been announced by TNA's resident Director of Authority Santino Marella and will see all champions in TNA Wrestling face their challengers in a colossal 16-person intergender tag-team match. The teams break down as follows:





At this time, there's no word on whether there will be any type of prize for the winning team, and it's believed that this will be a non-title match. With that said, the winning team will have plenty of bragging rights going forward.

This match could have huge ramifications for TNA's next monthly special event, which will be Against All Odds. The show will take place on June 14, from the Cicero Stadium in Cicero, Illinois. At this time, no matches have been confirmed for the show.

The May 16, episode of TNA iMPACT will also see Ash By Elegance take on second-generation star Xia Brookside. Alan Angels will face off against the high-flying Leon Slater on the show.
