Final Smash Explained (Finally)

It seems that we've been given two nice updates to the SB Dojo site once again. Together, the two explain the "Final Smash" item that we have seen in the trailer. It is an item that, when picked up, will cause your character to glow. While they are in this state, you can press a button to use their final smash, a powerful, often long-range attack. So far, they have only shown us Mario's, which consists of a large blast of fire.
