Today's Smash Bros. Dojo update reveals an item specifically for the Adventure modes. The Trophy stand is an item you use to capture different enemies in the game. First you weaken them, and then you toss the little disc at them to reduce them to a miniature for your own personal collection. Yep, it's pretty much a Pokeball (or "Pokedisc") like in the Pokemon games. You can even take out the major bosses this way, and you can come back later to just fight the bosses; so you don't have to capture them the first time around.
