This article needs a big cleanup.

This has the category "Ice Warriors", but the text makes no mention of them. Is this speculation, or is it stated in the story that Martian karate comes from them?

These problems might be so great that the article's factual accuracy has been compromised. Talk about it here or check the revision history or Manual of Style for more information.

Martian karate was a formidable form of karate known by the Third Doctor.

When he was attacked by Primords, the Doctor attempted to stop them using Venusian aikido. When this didn't work, he then moved onto the Martian karate, but neither method proved effective in stopping the Primords. (PROSE: Inferno)
