Kevin Holland is basically Batman at this point.
The UFC star just took matters into his own hands and stopped a crime dead in its tracks -- AGAIN -- this time, subduing a gunman at a sushi restaurant.
The 29-year-old welterweight was at Ra Sushi in the Highland Village of Houston around 11:30 PM on Monday ... when witnesses say someone entered the restaurant and fired a gun into the air.
But while most of the folks in attendance ducked for cover, three customers -- including Holland -- rushed to stop the alleged shooter.
