Los Santos Kings is a Hockey team based in Los Santos. The team's logo resembles that of the LA Kings.
The LSK (Lost Santos Kings) is known as a failing and violent team, as mentioned in Radio Los Santos in GTA V:
"Our home team, the LS Kings has just lost another game to those Venturas assholes... But, LSK being mostly ex-gangsters and mobsters, several players of the Venturas team got beat up, and three of them are currently in Mount Zonah! Go Kings!"
