Trivia

 * Unlike the other characters, Gaige's in-game default skin differs from the one used in the official promotional images. The actual in-game version has a much bleaker, less saturated look.
 * Gaige's Sinful Sweetheart head is a reference to Ema Skye, of the Ace Attorney series, specifically her haircut as an adult in Apollo Justice: Ace Attorney.
 * Gaige's Speak No Evil head appears to possibly be the skinned remains of Max, from Sam & Max, bearing the same beady, black, eyes and razor sharp 'bear-trap' teeth as the franchise's titular psychotic bunny.
 * Gaige's Lovely Corpse head could be a reference to the film and book The Lovely Bones.
 * Gaige's Metal Blood head is a reference to Tali'Zorah vas Normandy, of the Mass Effect series. Like Gaige, Tali is also an engineer with a talent for robotics, and shares Gaige's ability to summon a robotic companion to assist her in battle(in her case, a holographic drone).
 * Gaige's Digitized Death head could be a reference to the Necrons of Warhammer 40,000.
 * Gaige's Grease Monkey head is a reference to Winry Rockbell, of the anime Fullmetal Alchemist.
 * The skin "Horrible Religion" is inspired by the School Uniform of Miku Hatsune, a famous Virtual Idol in Japan. The colors are exactly the same in the right place.
 * The Skins "Streets Ahead" and "Cool Cool Cool" are references to the show Community, as catch phrases for some of the characters.
 * Some of the skins are references to punk and post-punk bands, fitting in with Gaige's "punk" theme/Anarchy/Punk class mods. Miss Ramone (The Ramones), YESFX (NoFX), Horrible Religion (Bad Religion), Joy Divide (Joy Division) and Distorted Socially (Social Distortion). Some reference songs: Sun Blister (Blister in the Sun by Violent Femmes), Ecstatic Tuesdays (Manic Monday by The Bangles), and Don't Call Her Green (Don't Call Me White by NoFX).
 * The skin "It's Always Sunny On Pandora" is very likely a reference to the show "It's Always Sunny in Philadelphia " on FX.
 * The skin "Angry Machine" is likely a reference to Futurama, specifically the character Hypnotoad; the sound effect used for Hypnotoad is also called Angry Machine, and when the skin is combined with the Fragger hat, the hat's colour is similar to that of Hypnotoad.
 * "A Study In Red" is a reference to the detective mystery novel written by Sir Arthur Conan Doyle. Titled " A Study in Scarlet"
