Shoulder angel
A shoulder angel is a plot device used for either dramatic or humorous effect in animation and comic strips (and occasionally in live-action television). The angel represents conscience and is often accompanied by a shoulder devil representing temptation. They are a useful convention for depicting the inner conflict of a character. Usually, the angel is depicted on (or hovering near) the right shoulder and the devil or demon on the left, as the left side traditionally represents dishonesty or impurity.
Iconography
The shoulder angel often uses the iconography of a traditional angel, with wings, a robe, a halo, and sometimes a harp. The shoulder devil likewise usually looks like a traditional devil with reddish skin, horns, barbed tail, a pitchfork or, more precisely, a trident and in some cases, cloven hooves. Often, both resemble their host, though sometimes they will resemble other characters in the story who are responsible or mischievous. In Western culture the idea develops the Christian concept of a personal guardian angel, who was sometimes considered to be matched by a personal devil who countered the angel's efforts. Especially in popular medieval dramas, like the 15th century The Castle of Perseverance. In both this and Christopher Marlowe's play The Tragical History of Doctor Faustus, of about 1592, the "Good Angel" and "Bad Angel" offer competing advice (Act 2, scene 1, etc.) to the hero.
Origins
The non-canonical Early Christian book, The Shepherd of Hermas, of around A.D. 140–150,[1] has a reference to the idea of two angels, There are two angels with a man—one of righteousness, and the other of iniquity. (Sixth Commandment, Chapter 2). These angels in turn descend into a person's heart, and attempt to guide a person's emotions. Hermas is told to understand both Angels, but to only trust the Angel of Righteousness. The concept is similar to ideas of personal tutelary spirits that are very common in many ancient and traditional cultures.
In some traditional Christian belief, each person has a dedicated guardian angel whose task is to follow the person and try to prevent them from coming to harm, both physical and moral. At the same time each person is assailed by devils, not usually considered as single and dedicated to a single person in the same way as the guardian angel, who try to tempt the person into sin. Both angels and devils are often regarded as having the ability to access the person's thoughts, and introduce ideas.
Similar beliefs
There is a similar Islamic belief of Kiraman Katibin, two angels residing on either shoulder of humans which record their good and bad deeds. However, these angels do not have influence over the choices one makes, and only record one's deeds. However, there is a concept much similar to the shoulder angel and devil which is of the Qareen. The Qareen, according to Islamic literature, is a personal companion, and there are two with each individual, one from the angels and another from the Jinn. The word qarīn literally means 'constant companion'. The angel pushes the individual to do good and obey God while that from the Jinn does the opposite.
Modern representations
In several modern fictional stories, a character can be marked as especially evil or mischievous by receiving similarly bad advice from both shoulder figures, having a second shoulder devil instead of the angel, or being persuaded by the devil to kick the angel out.
One may view this image in Freudian terms, with the Angel representing the Super-ego (the source of self-censorship), counterbalanced by the Devil representing the Id (the primal, instinctive desires of the individual).
The Disney animated film The Emperor's New Groove, its sequel Kronk's New Groove, and the animated series The Emperor's New School feature the concept of shoulder angels and devils, most notably in the character of Kronk. His appear at various points of moral crisis in the franchise for Kronk, but often spend more time antagonizing each other than actually trying to take Kronk down one path or another. The Oscar-winning Disney short Lend a Paw also featured Pluto being influenced by a shoulder angel and devil, and Pete has similar manifestations—though simply colored white and red rather than depicted with wings and a halo/horns and a pitchfork, respectively-in episodes of Mickey Mouse Clubhouse.
The film Cloud Atlas is an example of utilizing a shoulder angel plot device in feature film, in which the character of Hugo Weaving whispers bad and good advices to the character of Tom Hanks. Old Georgie (Hugo Weaving) appears only in critical points of the story, where Zachry's mind (Tom Hanks) is split between right and wrong choices.
BYUtv's sketch comedy series Studio C makes use of the concept in several sketches, with the physical comedy aspect of the angel or devil-a full-sized being played by an actor-having to physically climb up onto the shoulder of the one they are attempting to influence for good or evil.
It is speculated that the two main protagonists of Neil Gaiman and Terry Pratchett's Good Omens are supposed to represent the angel and demon on your shoulder as the Demon Anthony J. Crowley tempts people into sin/ baser nature while his counter figure the Angel Aziraphale encourages people to do good and rise above their baser instincts, however neither forces people into following their examples allowing free will to be exercised unimpeded.
In The Simpsons episode Whacking Day the concept that everyone has a good and a bad self is discussed at the end of show while Homer imagines his evil version dancing on the grave of good Homer while singing 'I am Evil Homer, I am Evil Homer' indicating that within him the battle for good and evil has long ago been won by his bad angel.
In fiction
In the Discworld novel Nightwatch by Terry Pratchett the killer Carcer was considered by the hero Samuel Vimes to have a demon on each shoulder rather than an angel and a demon, but not opposing each other, just in competition to urge Carcer on to worse deeds. It was said that if Vimes looked deep into Carcer's eyes, he could see the demons looking back.
The The Adventures of Tintin comics used this concept in at least two stories The Red Sea Sharks, where Captain Haddock's good and bad angels try to convince him to drink a bottle of whisky. The bad one is able to convince him, but the bottle smashes before he is able to drink it, leaving the good angel victorious. In Tintin in Tibet Snowy is tempted by his demon to enjoy a huge bone rather then deliver a vital message. His good angel loses the argument leaving in tears, and he gnaws the bone while the message blows away. Realizing his mistake, Snowy makes amends by reaching a local monastery and brings the monks to help.
In both examples, the angels resemble good or bad versions of their subject, with horns and angel wings.
Sluggy Freelance comics has made use of this theme, with all three of the main characters; Riff, Torg and Zoe having been shown debating with their shoulder angles and demons. Despite being good and bad they both still reflect aspects of their owner - both Riff's are unwilling to commit to a course of action saying 'don't know' when asked for guidance. Torg's angle and demon are both childish while Zoe has her bad demon dressed in revealing outfit, while her good one wishes she could dress in the same fashion.
