Play Fight Fighters

You head over to Fight Fighters, one of your favorite games.  There's a kid there playing, a young boy with a blue hat with a pine tree on it.

"Hey!" he says.  "I'm Dipper.  Want to play head-to-head?"

"Sure!" you say.  You put in a quarter. 

"CHOOSE YOUR FIGHTER!" the system booms.

"You go ahead and pick first," Dipper says.  "But be careful.  This game can be pretty crazy."
