For an SCAW Superstar to become a Grand Slam Champion, they need to have had an SCAW Championship reign, an SCAW Internet Championship or SCAW Legends Championship reign, SCAW Zero-One Championship or SCAW Hardcore Championship reign, and a SCAW Tag Team Championship reign. Grand Slam Championships involve a world title (SCAW), a Second-Tier title (Internet or Legends), a Tertiary title (Zero-One or Hardcore) and a tag team title.
