Luchadores spend years perfecting a mixture of complex dance moves and athletic floor routines. Their identities are protected by their distinctive masks which are worn whenever the luchador is in a public place - it is a dishonour and insult for the mask to be removed. Rudos are the villains and often represent corrupt officials or dishonest policemen. Técnicos are the heroes who fight on behalf of the common man, workers and the poor.
