Sorry anon, but no. No Gardevoir or anything from its line from what I saw. I was hoping for that myself though.
A Machamp did show up during a later sequence when the villains Ditto turns into a bunch of different things to beat up the MC.
I was hoping at least one of my main team would show up, and since they're Gardevoir, Aegislash, Toxapex, Tsareena, Ditto and Porygon-Z, only one of those showed up but it got a cool scene so I'm pretty happy.
