All of Mario's voice clips from Super Mario Strikers, provided by Charles Martinet and reused in Mario Strikers Charged. This is perhaps the most energetic Mario has ever sounded in a game, and his voice is arguably even more highpitched here than in Mario Kart 8. Can't say I blame him, what with the Strikers games being far more intense than any other Mario spinoff.
