Shaquille O'Neal is moving on from his longstanding feud with Dwight Howard ... saying he has officially "deleted" his nemesis from his life.
The beef has been well documented over the years ... and initially, it mostly stemmed from Howard taking on the "Superman" nickname, which Shaq was known to use over the course of his Hall of Fame career.
Howard revisited their history during a recent podcast episode ... saying he was so pissed off over it all, he considered showing up at the TNT studios to confront Shaq -- as an old-fashioned beatdown might be the only way to resolve their issues.
