Putin is the big scary monster heel. Zelensky is the plucky underdog babyface.
Here's how this match will play out.
Putin will dominate early and get the heat on Zelensky. Zelensky will get the comeback, and just when it looks like he's getting the upper hand and he's showboating a little to the crowd, BAM Putin will hit him out of nowhere with a pile-driver and win the match clean with a three-count in the center of the ring.
