Lawrence Okolie, for a moment at least, stole the limelight on the night 78,000 fans descended onto the Principality Stadium to watch fellow Londoner Anthony Joshua defend his heavyweight titles.
The 24-year-old, like Joshua, has yet to taste defeat during his short professional career to date and there was no sense of the zero on his record disappearing in the Welsh capital on Saturday night.
For the first time in his first five fights, Okolie was taken the distance against Blaise Mendouo in his last bout, but it was clear the cruiserweight had no intentions of playing the waiting game again.
The Hackney-born fighter's career only started in late March, this year. However, it's now six wins to his name and it seems as though he has the potential to follow in similar footsteps as Joshua.
Okolie, too, is a former Olympian with a ruthless streak himself. And Mancunian fighter Adam Williams stood no chance against the Londoner who is quickly racking up plenty of experience.
The up and coming London fighter came out on the front foot trying to make a spectacle of his undercard fight, fully firing and landing some heavy hooks.
Okolie makes light work of Williams
However, despite Williams' defiance and bravery, Okolie made it clear he wanted the Mancunian down and out as quick as possible.
Williams was quickly forced onto the back foot as the 24-year-old made the most of having the upper hand by firing through the Manchester fighter's guard.
And the bout was waved off in the third round as Okolie refused to take prisoners and downed his sorry opponent with a destructive knockout.
Both referee and Williams' corner were in agreement, the 36-year-old had taken enough punishment and it was, quite rightly, time to call it a day.
A promising 2018 awaits Hackney fighter
However, while there was little to take from the bout for Williams, Okolie will be looking on at what lies ahead for him in what should be an exciting 2018 for the Hackney fighter.
Fight fans are now just hoping, and fair to say somewhat expecting, that Joshua can deliver a similarly destructive job against Carlos Takam.
