Hood

The Hood is the main villain and adversary of International Rescue in the Thunderbirds TV series.

The name "Hood" was derived from the term "hoodlum";
Gerry Anderson also observed that the character was frequently masked, and that a mask "could be described as a 'hood'."
Sylvia Anderson acknowledges that the Hood's appearances became less regular towards the end of the series (the character is absent from the six episodes of Series Two), explaining that, like Kyrano, the character "turned out to be less viable on the screen than on the page.
To strengthen the character's antagonistic appearance, the Supermarionation puppet was fitted with an over-sized head and hands.
