King Boo is not that evil as he is in the Mario games. While he does pull off some evil schemes, they are ridiculously stupid and usually fail. He was kicked out of scare school as well.
He was actually Poyo Rides first rival in Mario and Sonic. Anyone can say this if their first game was the Wii edition of winter Olympic games, but Poyo is talking about the London 2012 Olympics for the Wii.
- This is one of the reasons why his favorite event happens to be Dream Sprint.
He is Poyo Rides 3rd favorite Mario Kart Character, next to Bowser Jr. and Dry Bowser.
