There is no one individual who can be called the "world cricket king" as cricket is a team sport and individual performances alone cannot determine the success of a team.
However, there have been many legendary cricketers who have contributed significantly to their team's success and are widely regarded as some of the best players in the history of the sport. Examples include Sachin Tendulkar, Sir Don Bradman, Vivian Richards, Brian Lara, and many more.
It's worth noting that cricket is a sport played by many nations around the world, and different players may be considered as the best in their respective countries or regions.
