John IV - Matrix Ghost John After John in his human body dies, his consciousness is uploaded to a fragment of the Time Lord Matrix kept in the Doctor’s TARDIS.
John IV.5 - HoloJohn They project a hologram of John outside of the Matrix, just within the TARDIS, so he doesn’t have to be stuck in there all the time.
John IV.5 - RoboJohn They build him a robotic body and install his personality into it so he can travel with them outside of the TARDIS.
John IV.5 - (Robo)WereJohn During one of their adventures, they came across a lycanthropic virus that can apparently mutate to infect synthetic bodies, and John got infected with it.
