#2. Sage Northcutt (UFC record: 6-2; ONE Championship record: 0-1)
ONE Championship fighter 'Super' Sage Northcutt had the makings of a bonafide MMA star. Discovered by Dana White on his show 'Looking for a Fight', Northcutt showed tremendous potential to be the next UFC cash cow. His supermodel looks and insane skills brought him from the prelims to the main card in just his second UFC fight.
Though his overall UFC record isn't clean, one might say that Northcutt was mounting some momentum with three consecutive UFC wins before signing with ONE.

That's where it all went wrong for 'Super' Sage. The former UFC fighter was matched up against former 7-time world kickboxing champion Cosmo 'Good Boy' Alexandre. Instead of using an obvious advantage on the ground, Northcutt chose to test his might against the striking specialist. In a little over 30 seconds, Alexandre knocked out the American with a right hand that broke multiple bones on his face.

#1. Eddie Alvarez (UFC record: 4-3-1; ONE Championship record: 1-2-1)
Of all the ex-UFC fighters who have ventured to ONE Championship, no one has had a rougher go at it than Eddie Alvarez. The former UFC lightweight champion was welcomed to the ONE Circle in brutal fashion by the relatively unknown Timofey Nastyukhin via devastating TKO.
During his second bout, 'The Underground King' was getting chewed up on the feet by wushu specialist Eduard 'Landslide' Folayang. Alvarez barely survived if not for his come-from-behind submission win.
In his third bout, Alvarez was initially disqualified after allegedly hitting Iuri Lapicus in the back of the head. The decision was later overturned into a no contest after a careful review of the incident. Still, it's not a good look for the former UFC star.
In his fourth bout, Alvarez was handed his second loss in the promotion by Ok Rae Yoon via unanimous decision. Let's see how the former world champion bounces back from his rollercoaster of a run in ONE Championship.
