Richard B. Riddick (played by Vin Diesel), more commonly known simply as Riddick, is the antihero of three films in the Riddick series, namely Pitch Black, the animated movie The Chronicles of Riddick: Dark Fury, and The Chronicles of Riddick; as well as the two video games The Chronicles of Riddick: Escape from Butcher Bay and The Chronicles of Riddick: Assault on Dark Athena.

Within the canon of the series, he is shown to be a highly erratic and unstable individual – he is an extremely violent and dangerous convict, murderer and notorious sociopath, with other characters even going so far as to directly describe him as evil – yet despite this, he is sometimes shown to perform moral or even atypically heroic actions, usually against his better judgement.
