StreetSmash "???" Token

When playing StreetSmash, I recently encountered someone who should have the Shulk token. When I met them, the token said "???" on the token name, and the token image was a giant "?".

In the token select, there is no "???" or "Random" caracter.

btw they have the greeting

I will hack you

I have actually not asked them if they know real hacking, so I think "???" May just be his hacking.

But, I also think it's a waste of time to hack like this, so I think it may be an error with not connect in time, like when the communication get's inturupted.

I can't think of any other reasons of why this glitch/hack occurred.
