In Grand Theft Auto: London 1969 and Grand Theft Auto: London 1961, the protagonist is a character chosen by the player to follow the game's story. Whatever the choice, it will not change game's plot.
Like Grand Theft Auto, players are given the option of choosing one of out eight protagonists in both Grand Theft Auto: London, 1969 and Grand Theft Auto: London, 1961, each having their own default full name (which the player can change), but otherwise have very little difference in gameplay aside varying colors of clothing (aside the bell-bottom pants they wear in GTA London 1969, which distinguish them from the GTA and GTA London 1961 renditions).
Unlike GTA and GTA 2's protagonists and GTA London's in-game depiction of other characters, the protagonists are depicted with hand-drawn, stylised art direction appropriate for the 1960s setting the game is set in, and appearing solely as Caucasian men in 1960s fashion and hairstyles. The appearance of certain characters are also based on various real-life celebrities as they appeared around the time.
List of protagonists
Grand Theft Auto series
|Maurice Caine||His name and appearance are based on famous British actor Michael Caine. Most notable is his performance in the 1971 crime film, Get Carter. Maurice is Michael Caine's real first name.|
|Mick Casey||Casey is depicted as a beefy and rough thug, in contrast to most other protagonists who display some degree of fashion sense and generally appear less oversized.|
|Johnny Hawtorn||The character somehow looks like Johnny Cash, but with Elvis sideburns and the threatening attitude of James Dean.|
|Winston Henry||Henry's attire is an apparent nod to both the beatnik subculture as well as the newer mod subculture, donning a trilby as well as featuring a turtleneck and sideburns.|
|Charles Jones||Jones' long-haired and thick-bearded appearance appears to be inspired by the hippie sub-culture. The name 'Charles' and his beard are also references to Charles Manson.|
|Rodney Morash||Seemingly inspired by the Mod sub-culture, Morash is by far one the more frequently featured protagonists from the game, having been additionally illustrated in another artwork for the game, holding a shotgun. The aforementioned artwork has also been adopted for use as a Rockstar Games Social Club user avatar, the only one to represent the "Grand Theft Auto: London" category, and his appearance may hold a certain resemblance to The Beatles' bassist Paul McCartney.|
|Sid Vacant||His name and appearance are based on the Sex Pistols' bassist Sid Vicious. The band released a song titled "Pretty Vacant" which explains his last name.|
|Wolfie Vilans||Looks to be quite artistic and pretty wealthy. His appearance is most likely based on Only Fools and Horses character Aubrey 'Boycie' Boyce.|
