Companions are controlled via the Companion wheel. Companions are special non-player characters who follow the player, aid them in combat, and provide a unique perk as long as they're in the player's party (whether following them or waiting the perk stops applying when they're dismissed).From left to right: Rex, Rose of Sharon Cassidy, Raul (Vaquero outfit), Lily, Boone (assault armor), ED-E, Veronica, and Arcade. All eight permanent companions in Fallout: New Vegas.
