In the game, Luigi moves the ball...without his hands. Basically, Luigi uses psychic powers to toss the ball at the goalie. :/
Wario eats the ball, blows up like a balloon, then shoots it at the goalie at high speeds.
These are just a few of the very strange and unusual powers the Mario gang has kept hidden from the public until this time. And all it took was a very angry soccer game to bring them out.
So to answer your question, I guess I like Wario and Luigi's mega strikes.
