Serena versus Luke
The Nathalia Strogueher knockout was not sudden, but a consequence of combinations of several factors. From the beginning, Nebezial made it clear that he was superior, both by his posture on the field and also by how he watched each Playoffs battles paying attention to the skills and techniques of his potential opponents.
Still, it was a disappointment that Nathalia couldn't even make Nebezial bleed; in fact, no one could. And that was it, just a disappointment, not a surprise.
In the same way, it would not be a surprise if the 'Half-Wolf' lost now in the semi-final against Serena Daren. To many, she was like an alternate version of Nebezial, but with an overwhelming charisma and without a grumpy face.
