Lion, real name Olivier Flament, joined Rainbow Six Siege with Operation Chimera in 2018 as an attacking operator from the GIGN. His EE-One-D drone scan became one of the game's most recognisable callouts because it forces defenders to stand still or be tracked through walls. Clips of the scan area warning spread through Siege montages, Twitch highlights and soundboards, where players reuse the Enemy Spotted style alert for any moment someone is caught in the open online.
