The Kalichuras were a species native to the Althrace system. Led by Melanicus, a significantly larger Kalichura, they once waged war with the Lords of Althrace in their attempt to conquer the system. Melanicus was defeated and he retreated into another dimension. (COMIC: The Tides of Time)
Behind the scenes
What colour is a Kalichura?
The Tides of Time was originally printed in black and white in the pages of Doctor Who Magazine but has been colourised three different times. Just like Meeps, this has lead to inconsistent colours for Kalichuras, namely Melanicus.
In Doctor Who (1984), Kalichuras were coloured bright green by Andy Yanchus. In Doctor Who Classic Comics, Kalichuras were coloured yellow by an uncredited colourist. In Doctor Who Classics, Kalichuras were coloured bronze by Charlie Kirchoff.
