It was way back at PRIDE Total Elimination 2005 when Mauricio “Shogun” Rua burst onto the MMA scene, seeking revenge for his younger brother’s controversial split decision loss to Quinton “Rampage” Jackson at PRIDE 29. The opening round of the PRIDE 2005 Grand Prix started off with a bang, when Rua dished out a beating from the opening bell.  He put Rampage down against the ropes and unleashed soccer kicks of fury until the ref said no more.

When Rampage crossed paths with Shogun after two gut wrenching losses Wanderlei Silva, more head trauma was headed his way. Rua headed into the fight with every career win coming by way of knockout. Rampage was in a world of hurt once Shogun began to land knees to the head. Rua’s unrelenting clinch took the life out of his opponent.

Jackson would sign with the UFC three fights later to avenge an earlier career loss to Marvin Eastman before knocking out Chuck Liddell for the light-heavyweight belt.

After Shogun matched “The Axe Murderer’s” performance on Rampage, he would go on to beat Antonio Rogerio Nogueira, Alistair Overeem and Ricardo Arona to become the 2005 PRIDE GP champion. Shogun then went on to fight Mark Coleman, where he suffer a broken arm less than one minute into the fight. Then he would score four-straight wins before eventually finding his way to the Octagon.

Rua lost  his UFC debut to Forrest Griffin and then he went on to become light-heavyweight champion by knocking out Lyoto Machida, handing the Shotokan Karate fighter his first career loss in one round at UFC 113.

The Muay Thai machine is now set to scrap with Chael Sonnen at UFC on Fox Sports 1: 1 in August. If the Shogun of old shows up, Sonnen can get stopped for the third time in a row and possibly seal the deal on Sonnen’s retirement.
