Tecnicamente, nem sempre, em " Uma Criança Sobrenatural " somos apresentados ao TARDIS e parece que é o primeiro vez que o circuito camaleão falhou. O médico diz:
It's still a police box. Why hasn't it changed? Dear, dear, how very disturbing.
Isso estabelece que a TARDIS está agora presa como uma caixa policial, mas Susan revela que nem sempre foi uma caixa policial:
SUSAN: It should have changed. Wonder why it hasn't happened this time.
BARBARA: The ship, you mean?
SUSAN: Yes, it's been an Ionic column and a sedan chair.
BARBARA: Disguising itself wherever it goes.
SUSAN: Yes, that's right. But it hasn't happened this time. I wonder why not.
Na série " Ataque dos Cybermen ", a TARDIS muda várias vezes depois que o Doctor tenta consertar o camaleão o circuito. Primeiro, em uma cômoda ornamental, conforme descrito no script abaixo:
DOCTOR: This looks familiar.
PERI: Where are we?
DOCTOR: Scrap yard.
PERI: I didn't mean that. I meant, whereabouts on Earth are we?
DOCTOR: London.
PERI: It didn't change.
DOCTOR: Hmm?
PERI: I thought you said it was going to blend into its surroundings.
DOCTOR: Oh, she's probably thinking about it. Come on, let's find out where those signals are coming from.
(The Tardis changes into a highly ornamented dresser.)
PERI: Oh, neat, Doctor.
DOCTOR: Neat?
PERI: Very neat. I mean, there's nothing at all incongruous about that.
DOCTOR: Well, she hasn't done it for a long time. She's out of practice.
PERI: Of course, Doctor.
Aqui está a TARDIS mostrada na metade da transformação e como a decoradora final.
Mais tarde, ele se transforma em um órgão de tubos (como na foto) e o Doctor o reproduz brevemente.
(The Tardis materialises in Lytton's junk yard as a small pedal pipe organ.)
DOCTOR: This is getting ridiculous.
PERI: I'm not saying a word.
DOCTOR: I was certain I'd fixed it.
(He pulls out a stop and plays the opening line from JS Bach's Toccata and Fugue in B Minor.)
E, finalmente, ele se transforma em um portão.
(A pair of large wrought iron gates, the sort you'd find at the entrance to the driveway of a very large house, materialise in a corridor. The Cybermen lead their captives out.)
GRIFFITHS: What happened to the organ?
PERI: Do you really want to know? Oh, this place is so cold!
A TARDIS também é mostrada sem disfarces em " O nome do médico " cilindro cinza prateado.
Isso varia um pouco das TARDIAS não disfarçadas exibidas na série " Jogos de guerra ".
