#2 Kevin Owens and Sami Zayn
Fight forever was a chant perfectly created for Kevin Owens and Sami Zayn. Brought up together from Canada into the independents as the closest of friends and eventual partners, the former duo of Kevin Steen and El Generico took ROH and PWG by storm including winning the tag team championships.
However, as it often does, fractures formed giving us the ultimate heel version of Steen to combat the underdog from the underground.
The duo came to highlight the latter years of ROH's past decade, in timely battles of epic proportions all building to a ladder war at Final Battle. The feud and their friendship are so hot, it has carried over to NXT then WWE.
Despite many feeling that Owens has gone way beyond Zayn, who was in fact signed before him, there isn't a moment where Owens has been able to outrun this partnership.
That for any second after Zayn's return by his friends' side, there is a fear that they will fight again means how explosive this relationship is. It's artistry of a higher order between brotherhood and hate, trumped only by one coupling defined by pure love.
