Spirits of the Jungle ( comic story ) Summary . Part one . The Twelfth Doctor and Clara are among a group of people riding a spacecraft entering the mesosphere of Unnamed BX - 4 . An unseen enemy fires at the vessel , and the Doctor estimates that they will crash in a mere two minutes . Clara reflects on how the Doctor talked her into the experience ; at Coal Hill School , though the other specifics are not mentioned . Even earlier , the Doctor had a conversation with Mr Hitch , who knows of a sentient super - weapon called the Hadax Ura that went awry . Hitch is the only one who knows where the weapon is , and he has elected to combine his muscle and Blueboy ' s piloting skills to make a recovery team . Hitch asks the Doctor to join the team , using his technical expertise to its advantage . . . Back in the present day , the recovery team uses jet packs to reach the planet . The ship ' s crash conveniently means that the group has been given up for dead , despite actually being alive . Supposedly , the attack came from the Hadax Ura , which the group plans on approaching . The Doctor and the rest of the team encounter hostile Pterosaur s , which the team narrowly escapes . Clara , however , is nowhere to be seen , and she has presumably dropped into the jungle canopy . She could be anywhere . . . Clara lands in a lake , and is unsurprisingly lost in the jungle and covered in mud . The Doctor insists on finding her , and despite Gela ' s objection , Hitch agrees to satisfy the Time Lord . During the search , Hitch explains that the Hydrax Ura was developed by the Hub Alliance to end its war against the Axis Worlds , before escaping from its laboratory . Gela , meanwhile , feels like the jungle is somehow watching them , and indeed , the group is seen through a high - tech view - screen . . . The group encounters a hostile group of primitive Anthropoid s . The species is usually nonthreatening , so the Doctor speculates that the Hadax Ura cybernetically augmented them to find the group - which they have succeeded in doing . And after the Anthropoids are knocked out , a bigger creature arrives on the scene . Clara , meanwhile , hears a noise in the forest . The source of the sound is revealed to be . . . Danny Pink ! Part two . The Doctor recognises more cybernetic implants on the creature . He throws his sonic screwdriver into its mouth , knocking it out with a " sonic brainstorm " . Getting the device back proves to be unpleasant . . . Clara disbelieves Danny ' s identity , since she knows he is dead . She instead assumes the man to be a clone , shapeshifter or robot . Danny recalls a memory with Clara ; however , when she asks him about his favourite primary school teacher , he is unable to remember . Clara claims that nobody forgets his favourite primary school teacher ; in reality , he doesn ' t know because she doesn ' t . Clara realises that this copy of Danny was made from her memories . He admits that this true ; he took on Danny ' s form so Clara would trust him . Clara is not happy about this . . . No - one other than the Doctor wishes to find Clara ; if they do not find the weapon it will keep trying to kill them . The Doctor , however , insists on reaching his friend without them . He encounters another creature , and this time the sonic screwdriver proves useless . The rest of the group has gotten lost . Contacting Blueboy to get the weapon ' s location , Wiremu accidentally reveals themselves to the Hadax Ura . A group of hostile creatures immediately arrives . . . The Doctor manages to escape the creature , finally finding Clara . The Danny duplicate explains that it is an organic avatar created for the group ' s assistance - an avatar for the jungle . It explains that the entire jungle is a computer : the rivers are data streams and the trees are information servers . As the Doctor explains , " Any sufficiently advanced technology is indistinguishable from nature ! " The Hadax Ura is enslaving the creatures of the jungle , turning them into " tools of war " ; the Danny duplicate urges the Doctor to destroy or move the weapon . Unfortunately , though , the three are standing on a cliff overlooking the Hadax Ura , and there is no clear path to it . The rest of the group encounters a partially mechanic creature , this one claiming to be the Hadax Ura itself . It plans on converting the group into soldiers . The Doctor arrives at that instant , explaining that the weapon wants to end war by wiping out both sides . Using the sonic screwdriver , the Doctor causes some machinery to explode . However , the Hadax Ura servants grab Clara . . . and convert her into a technological being loyal to the Hadax Ura . . . Part three . The cyborg Clara orders the Hadax Ura ' s servants to place the team in the augmentation chambers . However , it turns out this being is not Clara at all - it is the avatar which previously took the form of Danny . The avatar goes against the weapon ' s orders , halting all the conversions and releasing all of the subjects . The Hadax Ura pleads for it to stop - it chose this world out of billions due to its vast information network which the weapon could use to augment its own consciousness . Nevertheless , the avatar preforms a complete systems shut - down and engages safety mode , shutting off the Hadax Ura . Mr Hitch has been injured in the struggle , but he is just barely still alive . The partially converted Wiremu , however , is dead . With the computers shut down , the Hadax Ura ' s true form is apparent - a mere small technological orb . However , that device is simply the weapon ' s controlling intelligence ; it supposedly " cannibalised its propulsion system " to build the room in which they are standing . Soon , the jungle avatar , once again in Danny ' s form , congratulates the Doctor on saving their world . As the team boards its repaired spacecraft , he Doctor wonders whether the Hadax Ura could really have been tricked so easily . He and Clara are not yet on the ship , so Gela exits to in search of them . It does not take long to find the time travellers . Unfortunately , though , the ship takes off before they can board it . The Doctor locates and utilises one of the jet packs which the team used earlier , managing to grab onto the spaceship . But Gela , turning into a mechanical hybrid , announces that the Hadax Ura has secured the ship . As it turns out , the weapon was forcibly confined to the jungle , and the humans were lured to the planet as a means of escape . The Doctor , discovers that Hitch has been converted as well , and that the actual weapon is now connected to him . The Gela hybrid considers Clara to be disposable " excess baggage " . However , the organic avatar returns to the scene to stop the weapon - and this time , it has brought the whole jungle . The various animals attack and presumably destroy the hybridised humans , leaving only Hitch and the orb remaining . On the spacecraft , the Doctor simultaneously opens the inner and outer airlock doors . As the Time Lord holds on to a handle , the Hitch - weapon hybrid rushes out the ship into space ; with no propulsion system or heat shielding , the Hadax Ura ( along , unfortunately , with Hitch ) will burn upon re - entry to the planet . Later , the Doctor lands his TARDIS on the planet to pick up Clara . The avatar , still in the form of Danny Pink , reminds Clara that the real Danny will always survive in her memories . As Clara leaves with the Doctor , she urges him to never bring her back to the jungle - she has had enough goodbyes . Plot . " to be added " External links . " to be added "
