Outer plasmic shell

An outer plasmic shell, often simply called a plasmic shell, was a TARDIS exterior.
== Characteristics ==
In a perfectly functioning TARDIS, the chameleon circuit picked a plasmic shell suitable to the time and place in which the ship landed. A TARDIS's shells were stored in the shell room; if the room had no suitable shells, more were created and stored as well. (PROSE: ) Lord Roche was forced to use a non-terrestrial aeroplane as his shell when he didn't have any terrestrial designs in his shell room and didn't feel like designing any. (PROSE: ) The theory in the TARDIS Handbook was that the plasmic shell was driven by the chameleon circuit. (TV: ) When a TARDIS died or was dying, its final plasmic shell might grow to enormous size due to leakage of its dimensionally transcendental interior. (TV: )
The Second Doctor boasted that the TARDIS was made from the "hardest materials in existence", making it near impervious to harm. (COMIC: ) Indeed, firepower from Dalek gunsticks were unable to penetrate the plasmic shell. (AUDIO: )
 used his chameleon circuit to bond his TARDIS' plasmic shell with the Third Doctor's. (PROSE: )
Later, more sentient TARDISes could decide what to change into all by themselves. (PROSE: )
When the Doctor's TARDIS entered siege mode, its exterior took the shape of a cube etched with Gallifreyan writing. (TV: )
== The Doctor's TARDIS ==
Among plasmic shells used by the Doctor's Type 40 TARDIS were: a boulder, (AUDIO: , PROSE: ) an Ionic column and a sedan chair, (TV: ) a wooden kiosk, (AUDIO: ) a shed (PROSE: ) and a post box. (PROSE: ) However due to a malfunction in the chameleon circuit, caused by the Eleventh Doctor, (COMIC: ) the Doctor's TARDIS became stuck with a police box plasmic shell after leaving 1963 London. (TV: )
Whilst the ship was infected by Scratchman, vines grew through the windows of the exterior and wrapped themselves around the outer shell, causing the police assistance sign to fall off. (PROSE: ) 
The shell of the Doctor's TARDIS had deteriorated by the time Romana I travelled with the Doctor. After a near miss by a missile in Atrios orbit, (TV: ) she designed a routine to strengthen it, though the Doctor disabled it as he abhorred tampering. He regretted the action when a missile was aimed at the TARDIS in Proxima Major orbit. (AUDIO: )
For a short period of time, the Sixth Doctor managed to repair the chameleon circuit, resulting in the outer shell taking the appearance of a stove, an organ and a doorway. The shell eventually returned to the shape of a police box. (TV: )
In 1854, the TARDIS was struck by cannon fire which displaced the outer shell. This triggered the Hostile Action Displacement System, causing the TARDIS to retreat to the Time Vortex where it grew a new shell. The new shell was still a police box, but was coloured white. The remains of the old shell were used as fire wood by soldiers. (AUDIO: ) The outer shell later regained its normal blue colour. (AUDIO: )
During the Last Great Time War, the TARDIS’ outer shell showed signs of wear and tear. (TV: , )
By the time of the Tenth Doctor, the outer shell appeared to have deviated somewhat from the original design of a police box as DCI Billy Shipton noted that its windows were the wrong size. (TV: )
Whilst honing in on the Tenth Doctor whilst he was trapped by the Trickster, the TARDIS covered the outer shell in artron energy to fight the Trickster’s power. Clyde Langer was infused with the energy after he made contact with the outer shell whilst trying to board the ship. (TV: )
Whilst confronting the Prometheans, the Eleventh Doctor learnt that the police box shape of the TARDIS’ outer shell had become part of humanity’s race memory due to his many visits to Earth, even speculating it had paradoxically influenced the design of police boxes in the first place. He used this to his advantage to free humanity from the Prometheans’ control. (COMIC: )
In an alternate timeline, the TARDIS' outer shell retained the police box shape up through its final resting place as the Doctor's tomb on Trenzalore, though it grew to an enormous size due to size leakage. (TV: )
When the TARDIS' power was drained by the Boneless, the outer shell shrank, causing the Twelfth Doctor to be trapped inside. It became small enough that Clara Oswald was able to fit it in her handbag. After she tricked the Boneless into returning power to the TARDIS, the outer shell regained its usual size. (TV: )
When the TARDIS crash landed on Earth in the Crimean War after an encounter with the Flux, the door disappeared from the outer shell, preventing access to the interior. Trying to re-enter her ship, the Thirteenth Doctor found only windows on each side of the police box exterior. (TV: ) 
When the TARDIS created a time loop to save the Doctor and her companions from extermination by Dalek Executioners, the outer shell became covered in red cracks. After the loop ended when the Doctor destroyed the Daleks, the TARDIS' appearance returned to normal. (TV: )
