Love him or hate him, Quinton "Rampage" Jackson is one of MMA's most memorable personalities.
The former UFC light heavyweight champion may not be the man he used to be inside the Octagon, but he is still out to prove something.
Even if he is the only many on earth that believes he can still be the "Rampage of Old," Jackson has left us with memorable performances both in and out of the cage.
Tonight at UFC on Fox 6 we could see the last fight of Jackson's memorable career.
Here is a look at what brought him to this point.
Although Jackson would lose his third fight to Marvin Eastman, he would go on an impressive eight-fight winning streak.
During this streak, Jackson would pick up four wins by submissions, yes submissions, and two by TKO.
Jackson was starting to get noticed by bigger companies, one of course being PRIDE.
In 2001 Jackson made his PRIDE FC debut against Japan's own Kazushi Sakuraba.
Sakuraba was one of Japan's most beloved MMA fighters at the time, and was coming off of a loss against Wanderlei Silva.
Although Jackson lost the fight to Sakuraba, he put on a good show, slamming the Japanese wrestler and putting up a good fight despite being the less experienced of the two.
Jackson would go 9-1 in his next 10 fights.
Of those nine wins, seven were by (T)KO.
This includes wins over former UFC champions Murilo Bustamante, Kevin Randleman, and Chuck Liddell.
The wins against Bustamante and Liddell set up a fight in the 2003 middleweight grand prix final against Wanderlei Silva.
During Jackson's run in Pride, the man to beat was Wanderlei Silva.
Silva was the most brutal fighter in the company and was its middleweight champion at the time.
If there was ever a fighter that could stop Silva, many thought it was Jackson.
The two men first met November 9th 2003 in the final of Pride's middleweight grand prix.
During the fight Jackson took down Silva and caused him to bleed. After the ref stood the fight up, though, Silva took advantage and gave Jackson his first career knockout loss by knees.
In their second fight nearly a year later, Jackson started off getting the upper hand on Silva.
Jackson floored Silva and scored some takedowns in the first and second rounds.
But Silva was able to take advantage once the fight got back on its feet and ended the fight once again by devastating knees to Jackson's head.
Jackson would have the last laugh when they met for a third and final time at UFC 92. After testing each other out, Jackson scored a knockout victory with a left hook.
The Jackson-Silva rivalry is known as one of the greatest in MMA history thanks to each one ending in a brutal knockout.
In between the first two Silva beatdowns, Jackson faced off against Ricardo Arona.
Arona was one of the top prospects coming into the fight and like Jackson, he was looking to challenge Wanderlei Silva for the middleweight title.
While going for Arona on the ground, Jackson got caught with an up kick that bloodied him.
Arona eventually caught Jackson with a triangle.
Instead of trying to use Jiu-Jitsu to maneuver his way out, Jackson picked up Arona while still in the triangle, and slammed him.
The slam was and still is one of the most memorable KOs in MMA history.
After the second loss to Silva, Jackson would go 4-1 in Pride and WFA.
Following his win against Matt Lindland, Jackson's WFA contract was picked up by the UFC.
Jackson's debut was against the man that gave him his first career loss, Marvin Eastman.
Jackson avenged that loss with a first-round knockout of Eastman.
Nearly four months later, Jackson found himself in a title fight against Chuck Liddell.
At UFC 71, Jackson faced off against Chuck Liddell for the second time in his career.
Much like the first time, Jackson knocked out Liddell in the first round. Liddell was the most beloved UFC champion at the time, and despite Jackson's resume, some may have been shocked that it was Liddell, not Jackson, laying on the canvas.
In his next fight, Jackson unified the Pride middleweight and UFC light heavyweight titles when he defeated Dan Henderson by unanimous decision at UFC 75.
Jackson would square off against The Ultimate Fighter 1 winner Forrest Griffin next at UFC 86.
Jackson and Griffin had faced off months prior to the bout as coaches on The Ultimate Fighter 7.
Although the bout was close, Griffin ended up winning by unanimous decision.
Jackson not checking leg kicks proved to be his downfall in the fight.
Although there were talks of protesting the decision and an immediate rematch, Jackson was involved in an hit and run incident that involved energy drinks and a police chase.
Over the next four years, Jackson would go 4-1.
This includes wins over Lyoto Machida and the last knockout victory he would have to date against Wanderlei Silva.
This time period also includes a feud with Rashad Evans, which ended with Jackson breaking a door on TUF 10, losing many of the fights he coached, retiring from MMA to play in the A-Team, and coming back to lose a subpar match at UFC 114.
While Jackson burned some bridges when he left the UFC to go act, he still was able to climb back into title contention to face Jon Jones at UFC 135.
Although he looked to be in great shape, Jackson earned his loss by submission in the UFC to Jones.
Jackson was looking to get back in the win column when he returned to Japan for UFC 144.
Although he claimed he was injured, Jackson showed up five pounds overweight for the fight.
Bader still accepted the bout and defeated Jackson by unanimous decision.
Shortly after the bout, Jackson announced that he was leaving the UFC once again.
Win, lose or draw, tonight's matchup against Glover Teixeira will be Jackson's final UFC bout...for now.
While it's hard to trust anybody's retirement talk these days, the bad blood between Jackson and the UFC could hold up.
Despite having a memorable career, Jackson has lost many fans over the years because of his mouth and antics outside of the Octagon.
Nevertheless, he is still one of the most entertaining figures the sport has ever seen.
