Sam Sinister, later known as Slyboots, was a villain in Adventurers Egypt theme. He was the partner of Baron von Barron. Both of them were out to follow Johnny Thunder and get the treasure for their own uses before he could. Sinister's personality was never expanded on much, and he dropped out after Egypt, with Baron von Barron becoming the main villain.
When the Dino Island theme came out, the Baron was now named Sam Sinister. When Orient Expedition was released, Sinister donned a new outfit which seemed to combine element from his original and Slyboots'. This whole situation has caused much confusion, leading to LEGO recently joking about it in the bios of the Detective.
Sam Sinister appeared in LEGO Racers as Sam Sinister and LEGO Racers 2as Slyboots (since Racers 2 took place after the name swap). He was also the goalkeeper of the Adventurers Villains team and also an out-field player in the Intergalactic team in the video game Soccer Mania; yet here he is referred to as Sam Sinister, after the name swap. Slyboots appears in five sets, but later disappeared.
