SD64CT II: 2nd round (beat Vampire Wario, lost to Samus)
Waluigi got a #4 seed, but soundly trounced by the Yoshis. At #9, he has another challenge, Marth-killer Vampire Wario. Ultimately, even if he does win, it's not good for Waluigi, as he has nothing that could stop Samus.
Comments
"Hopefully he'll have a better chance against Vampire Wario then everyone's favorite dinosaur. But once Samus comes to town, will any of this matter?

"He's gone in the 1st round, plain and simple. Lost to Yoshi as a #4 seed, so he's going down."
