What you guys think will happen when the 100th brawler comes?

So, we're not really near the big number, but i just Had the thought.

There's still a space for 1 more trio to Make 33 different trios (and to consideration, 99 brawlers), meaning the 100th brawler is going to be unique in a way. What are your theories? What you think they have in mind for the special day?
