@Mangaicc Not to mention Buu's colonoscopy and the Super Genkidama

[Javier L (Highwind) @BasNorth]

@Mangaicc Skip Buu saga? You're asking me to skip the Great Sayaman, Videl and Gohan, the Tournament, Dabura, Majin Vegeta vs Goku, Mr. Satan befriending Buu, Super Buu, Gotenks and his 'Ataque Kamikase de los Super Fantasmas', Gohan Mistico, Super Vegito and the whole series finale?
