And still. Two words synonymous with boxing champions, and two words that have followed Katie Taylor throughout her professional career, since securing her first world title back in 2017.
Seven years since turning to the paid ranks of the sport, following the disappointment of the Rio Olympic Games in 2016, Taylor has fought 22 times and won them all.
That first world title came after just seven fights, when Taylor defeated Anahi Ester Sanchez to claim the WBA World Lightweight title, and seven fights later, the Bray native became the undisputed champion, snatching that final WBC strap after an incredible scrap with long-time champ Delfine Persoon.
Seven successful defences of the entire lightweight collection, Taylor has accounted for all opponents, including the rematch, where she outclassed former champ Persoon at the second time of asking.
Legacy already assured, Taylor then took the sport to another level altogether, as she headlined, and sold out, Madison Square Garden, in what turned out to be a fight for the ages against seven-weight world champion Amanda Serrano – a split decision ensuring that the unblemished record would remain intact.
With little left to prove, and with the long-awaited Serrano return clash put on ice, Taylor's promised homecoming started to look like it was in doubt, until fighter turned matchmaker, as she called out Chantelle Cameron for this Dublin decider.
And still, Taylor will not want to hear those two words come fight night, as this weekend, champion becomes challenger, with the bout set in the super lightweight division.
At 36-year-old, Taylor is no longer interested in swatting away the mediocre mandatory minnows that are being offered at lightweight, and is now going after all of the big fights in and around her untouchable lightweight division to round off a remarkable career.
Taylor is moving up in weight in an attempt to take Cameron’s belts and will now fight at the 140-pound limit, compared to the standard lightweight 135.
But in truth, the weight class is not the story here, but rather the fact that two undisputed world champions will go head-to-head: a very rare commodity in the modern era of professional boxing.
Like Taylor, Cameron arrives into the Dublin bout with an unblemished record, winning all 17 of her professional fights, while she cleaned up the super-lightweight division in her last outing, defeating Jessica McCaskill in Abu Dhabi in November.
Katie has been here before, however, moving up back in 2019 to become a two-weight champion, defeating Christina Linardatou, to secure the WBO super-lightweight title.
And she has also previously shared a ring with Cameron, going right back to the amateur days when Taylor easily accounted for the emerging English fighter at the 2011 European Union championships.
Cameron admitted that she was starstruck on that occasion as Taylor was proving pretty much invincible a year out from her Olympic gold medal at the London Games.
But Cameron has since gone on to establish herself as one of the top pound-for-pound boxers in the women’s game as she set off on her own professional journey, and that amateur grounding has quite obviously stood to her as she has negotiated her way through the street-tough fighters in the paid ranks.
No more so than in her last outing against McCaskill; a true brawler and tough as nails, and a former foe of Katie Taylor, with the two meeting back in her first world title defence in 2017.
Taylor outboxed McCaskill in that York Hall encounter, however, she was also rocked by the unorthodox scrapper midway through the fight.
Cameron easily accounted for McCaskill, most notably in the early rounds, and there was an element of the Katie Taylors about the way she went about her business, staying on the outside of the dangerous opponent, coming in and scoring well with quick-fire combinations, while also proving more than capable of standing and trading with her teak-tough opponent.
Far from the case of master and apprentice, however, when Taylor and Cameron meet tonight under the bright lights of the Point Depot as big time boxing returns to Dublin.
But rather two incredible boxers who have come through the traditional ranks of the sweet science with both successfully moving out of the technical amateur game and into the white-hot atmosphere of the paid ranks.
During the build-up to most Katie Taylor fights, it has become the norm to discuss how an opponent might be able to become the first to inflict a defeat on the most decorated of sports stars.
Delfine Persoon, came close, Amanda Serrano even closer, losing out on a split decision, and despite the fact that Cameron comes to this contest as champion, she is also well aware of the fact that the pressure is on her to perform.
Taylor wins a straight-up boxing match, no question, however, 22 fights into her professional career, Katie is well aware that such events do not occur in the professional game.
Cameron is used to fighting at the heavier weight, which could indicate that she will possess more power than Taylor, however, she also fought a lot at lightweight and even super-featherweight, so there may have been a more pragmatic reason for going after the super-lightweight division.
The template is there, however, and Cameron will have gone through the Serrano fight forensically to attempt to both mimic that approach, while also adding enough to secure the decision.
Serrano was in peak physical condition for that Taylor fight, possessing the ability to absorb the champion’s pace and power, while also competent enough to slow her down and drag her into a brawl in the centre of the ring.
The naturally lighter opponent on that day just did not have the strength to finish the job when the opportunity presented itself midway through the fight with Taylor very much out on her feet and remarkably getting through to the bell at the end of the fifth round.
So that series of near unfortunate events will give Cameron real confidence going into this bout, and for that reason, expect her to start like a train, and it would not be surprising to see the English fighter approach this bout as a five or six rounder with knock-out proving the only way to securing the win.
Cameron has hinted as much in the build-up, throwing out the idea that the judges will give a close decision to the home fighter, but in reality, it just might be her best tactic to go home with the booty that she brought.
Taylor, of course, is as tough as they come, and while she will not want to find herself in such a situation again as she did during that brutal fifth round at Madison Square Garden, there was a real personal pride that she tested herself to the limit and came out on the right side of the Puerto Rican pummelling.
Two-minute rounds have certainly hampered Taylor in past fights as the short sharp nature of each episode allows opponents to hold on and get to the bell.
But it served her well in New York and it could also prove very useful should she end up in a similar situation tonight.
Katie loves a barnstorming bout every bit as much as those who have the privilege of watching the trailblazer at full flow, and while she will be keen as ever to put on a real display on her first professional bout on home soil, there will also be a professional approach to ensure that she makes it a winning return.
Taylor looked strong at the weigh-in, where both fighters tipped the scales identically at 139.7lbs, and she certainly will have the fitness, speed and skill to dominate against her esteemed opponent.
Expect Taylor to box clever for those opening stanzas, before dominating Cameron through the middle rounds, building up to a closing crescendo.
And should Cameron remain in the contest as the bell rings for the tenth and final time, strap in for two-minutes of spinetingling sporting action in its purest form, as perhaps Ireland’s greatest ever secures the homecoming that she more than deserves.
