[6] The main event of the telecast was a twenty-man Gauntlet for the Gold match in which 20 men sought to throw each other over the top rope and down to the floor in order to eliminate others, until there were two men left who wrestle a standard singles match to become the first ever TNA-era NWA World Heavyweight Champion.

[6] Ken Shamrock defeated Malice to win the vacant championship with Ricky Steamboat as the guest referee at the event.

[5] That same day, TNA were scheduled to produce their Sacrifice event, in which both Cage and Team 3D were to defend their respective championships.

[7] On the card, Cage was scheduled to defend the NWA World Heavyweight Championship against Kurt Angle and Sting in a three-way match.

At the first episode, broadcast on tape delay on May 17 Angle introduced himself as the "new TNA World Heavyweight Champion".

[1] but later on, Cornette stripped Angle of the TNA championship due to the controversial finish of the match at Sacrifice.

This match type involves five participants racing to gain a pinfall or submission to become eligible to hang a championship belt to win.

[14] The next bout pitted Chris Harris against James Storm on the June 7 episode Impact!, which ended in a double disqualification, therefore neither man advanced to the King of the Mountain match.

[15] The final qualification match was won by Christian Cage over Abyss on the June 14 episode of Impact!.

[16] Angle ended up winning the King of the Mountain match at Slammiversary over Joe, Cage, Styles and Harris, who was a mystery participant chosen by Cornette, to become the "undisputed TNA World Heavyweight Champion".

On the February 23, 2021, episode of Impact!, Executive Vice President Scott D’Amore officially sanctioned Moose's self-proclaimed championship.

[23][24] * Angle and Hardy wrestled another draw on the September 16 edition of Impact!, which led to Eric Bischoff making the final match at Bound for Glory a three–way.

Seven of the eight men were former TNA World Heavyweight Champions including Jeff Hardy, Chris Sabin, Bobby Roode, James Storm, Kurt Angle, Austin Aries, and Samoa Joe.

The eighth would be determined later in the night in a gauntlet match, which was eventually won by Magnus last eliminating Kazarian and Sting.

The center plate had faux diamonds aligned along its multiple rounded edges, similar to that of the Big Gold Belt.

Over the center plate was a large TNA Wrestling logo and below it the words "Heavyweight Champion" engraved in silver.

[32] This belt—modified with a white strap—returned in April 2020 after Moose declared himself as "TNA World Heavyweight Champion" following defeating several past TNA wrestlers, and with then-reigning Impact World Champion Tessa Blanchard being absent due to COVID-19 pandemic travel restrictions.

Moose's title would remain unrecognized until February 2021, when it became officially sanctioned and recognized by Impact executive vice president Scott D'Amore.

Following Slammiversary XV, both the TNA and original GFW Global Championship belts were used in tandem to represent the unification of both titles.

To reflect the change, TNA President Scott D’Amore presented Alex Shelley, who was the last champion under the Impact name with a new belt.

The center plate added more height with the top and bottom each pointed like a V-shape with the sides having various shapes.

The inaugural champion was Kurt Angle, who won the championship by defeating Christian Cage and Sting in a three-way match on May 13, 2007, at TNA's Sacrifice event.
