The Sarah Jane Adventures (2007)

A year after Torchwood premiered, the second spinoff was launched; The Sarah Jane Adventures was intended for a younger audience than the parent series, and the allowance for more juvenile humor meant that the Slitheen (and their fart jokes) from the main show were now entirely relegated to the spinoff. New Slitheen suits were made for the series, the difference being a new paint texture and new feet prosthetics (having claws rather than stubby toes), but the main difference was the addition of a 'Baby Slitheen' portrayed by Jimmy Vee in a latex bodysuit. The Baby Slitheen was sculpted by Charlie Bluett, with the animatronics inside the head by Richard Darwin and the paintjob by Rob Mayor.

Another alien that was originally from the main show was the Graske, originally made for features not part of the main series (like the interactive episode 'Attack of the Graske') but finally making proper appearances in this one; the Graske prosthetics were also painted blue in order to realize their cousin species, the Groske.

The Trickster introduced in 'Whatever Happened to Sarah Jane' was a prosthetic mask designed as a featureless face, with sunken eye sockets.

The episode 'Warriors of Kudlak' involved the titular warlord - a bug-like alien called an Uvodni - realized as a prosthetic latex mask with internal animatronics to make the eyes twitch, with additional hand prosthetics as well.

Eve in 'The Mad Woman in the Attic' was achieved as a prosthetic facial makeup around the sides of actress Eleanor Tomlinson's face, with a design implying here hair was growing out from underneath her skin.

'Prisoner of the Judoon' introduced Androvax, a reptilian 'Veil' alien played by Mark Goldthorn in heavy facial prosthetics, designed to resemble horned lizards. Many of the sculpting images of the aliens in Sarah Jane Adventures included in this entry come from the website of sculptor Valentina Visintin.

The Shansheeth in 'Day of the Doctor' were animatronic latex props worn like hats as the performer wore the rest of the costume to conceal themselves.

The Metalkind in 'Sky' were prosthetic makeups with goggle-like appliances embedded over the performer's eyes; the body was concealed by wearing armor originally used for 2004's The Chronicles of Riddick.

The cyclops-esque Scullion leader in 'The Man Who Never Was' was a latex mask worn by Dan Starkey; the mask had animatronic mechanisms allowing the eye to blink.
