“Kaz” is considered by many to be the strongest of the strong, and it’s hard to argue. The winner of the ’80, ’81, and ’82 WSM contests, Kazmaier was barred from competing in 1983 by the event’s organizers because it was assumed that so long as he competed, no one else would ever get the chance to savor victory. Kaz was the first man to lift all five McGlashen stones, which weigh between 90 and 160 kilograms (about 200 and 350 pounds). His 661-pound bench press stood as the world record for years, and if not for a pec tear shortly thereafter he would have surely bested it himself. His 2,425-pound total, set back in 1981, is still the record for raw (no bench shirt, no squat suit) powerlifting today.
Despite having been rivals with Gol D. Roger , Whitebeard held much respect for him. Not long before his death, Roger met with Whitebeard on an island to have what seemed to be an entirely cordial drinking session, with Roger even offering to give the location of Raftel to Whitebeard, and when Whitebeard asked Roger about the Will of the D. , Roger willingly told him about it.  Upon learning that Ace was his rival's son, Whitebeard did not see his bloodline as an inconvenience, and even tried to inspire Ace to respect Roger as his father.
