(6)GLaDOS vs (11)Mewtwo 2018

Ulti's Analysis
There are people pointing to this match as evidence of Mewtwo's FRAUDULENCE before the Tifa match even happened, but I highly disagree. This is pretty much exactly what Mewtwo was supposed to do against GLaDOS -- a boring 63-37 type of beatdown that gets chalked up into the ether of forgotten round one matches. Given he was only an 11 seed, only had 59% of people behind him, and is finally back in Smash Bros without DLC, I find this blowout fairly impressive. It's right in line with with the LOL x stats from 2010 and 2013.

As for GLaDOS, this is the best possible outcome for rallybait characters. You can catch and bandwagon and maybe win a contest, but after that your best hope is getting a middling seed and retaining a fraction of strength. GLaDOS and L-Block are the best examples we have of a life after rallybait (I know Portal never won anything, but it took over the internet in 2007 in the same way Undertale did in 2015). Some strength, maybe a win or two, and it's all good. What's happened to Draven is pretty much the exact opposite of what a rallybait character could hope for. We'll probably see GLaDOS and L-Block every year. I'll be shocked if we see Draven again.
