Captain Soto was the captain of the original Destiny’s Bounty and the man who imprisoned Nadakhan in the Teapot of Tyrahn. To do this, he used the venom of a Tiger Widow spider, which slowed the djinn down long enough for him to be captured. Soto hid a map to the Tiger Widow’s island inside a lantern on the Misfortune’s Keep, Nadakhan’s ship. Soto later wound up in the Kryptarium prison, where he encounters the ninja. He offered the ninja information on how to stop a djinn in exchange for their helping him to escape. He later joins Jay’s hastily thrown together team in a last-ditch attempt to defeat Nadakhan.

Captain Soto is a pirate and the original captain of Destiny’s Bounty, back in the long-ago days when it was a sailing ship. A sinister pirate, he perished many years ago but was brought back to life by Lord Garmadon’s Mega Weapon. He seized control of Garmadon’s ship and tried to return to his life of piracy, but was defeated by the Ninja and sent to prison.
