In the original novel, Jane was an American and Tarzan was the lost son of a British lord. In the series, not only is Jane Half-British, but she's also biracial.
Tarzan's, Kala's and Clayton's physical appearances are clearly based off Disney's adaption of Tarzan. Muviro's physical appearance is based off Basuli's physical appearance from Disney's Legend Of Tarzan.
Tarzan smashing the poachers' guns is a throwback to both the old Johnny Weissmuller films, where Tarzan developed a habit of smashing strangers' guns on sight after seeing several of his friends shot (and been shot at himself) and the Disney movie and TV series where Tarzan destroys Clayton's gun and physically disarms anyone who hold one in the TV series.
The series is set in modern times instead of being a period piece if one were to follow the books.
Tarzan and Jane are both 15 in the series.
