Dalip Singh Rana or The Great Khali, is an Indian-born American wrestler and actor, known for his stints in WWE between 2006 and 2018. He won the World Heavyweight Championship once in 2007. In 2021 he was inducted into the WWE Hall of Fame.

His first matches were in All Pro Wrestling in the United States, where he fought under the ring name Giant Singh. He was directly involved in the training accident that claimed the life of Brian Ong on March 28, 2001, the victim of a move made by Singh himself. Singh's responsibilities were actually not many, as two other people were present to guide Ong in the fall.

In the face of a correct execution of the move by Singh, there was an incorrect arrival on the ground of the young wrestler who died from the consequences of the fall. All Pro Wrestling was forced to compensate the wrestler's family with an amount of approximately one million three hundred thousand dollars.
On January 2, 2006, Singh became the first Indian wrestler to be signed by World Wrestling Entertainment (WWE); he was sent to their developmental promotion, Deep South Wrestling, where he wrestled under his real name.

The third of eight children, Singh started working as a teenager to support his family. Before joining the Punjab police force, he worked for some time in the mines of the Himalayas; in this period he began to practice various sports, succeeding well in each of them. Of all of them, Singh had a particular fondness for bodybuilding.
