"Lord" Sam Sinister/Sanister aka Baron Von Baron/Barron aka Mr. Hates aka Evil Eye, and not to be confused with "Slyboots", who was also called "Sam Sinister", is the main villain of the Lego "Adventurers" theme including the "Orient Expedition" subtheme. He is the arch–enemy and rival of hero Johnny Thunder and is clearly inspired by the Nazi enemies of Indiana Jones. His multiple alternate names are due to inconsistency on the part of Lego.
His official description from Lego: Lord Sinister is Johnny's arch enemy. He is selfish and evil, with no limits to his ambition or greed. He has a huge private collection of ancient and valuable treasures from around the world and is always on the hunt for more.
