Photon beam
The photon beam or photon-laser, also referred to as blaster ray in regards to K9 Mark II, (AUDIO: Ascension) was a laser weapon incorporated by Professor Frederick Marius into his invention, K9.
Characteristics[[edit] | [edit source]]
In standard K9 models, a "blaster-muzzle" came out of a hole at the front of the robot's head and it fired the beam. (PROSE: Doctor Who and the Invisible Enemy) However, in the case of K9 Mark I's later incarnations, such as K9 Mark 2, it was simply fired out of the hole. Several smaller holes inside also lit when the weapon was charged. (TV: Mind Snap) For Mark II (TV: The Ribos Operation) and early instances of Mark III, (TV: A Girl's Best Friend) the beam was red, although in K9 Mark I (TV: Regeneration) and III's later life, (TV: School Reunion) along with K9 Mark IV (TV: The Gift) and K9 Mark I's later incarnations, (TV: Liberation) the beam was a more orange colour.
Settings[[edit] | [edit source]]
The original K9 Mark I and Mark II's photon beams could stun and kill. In particular, Mark I's one had four levels of intensity; among them, "kill" and "paralyse". (TV: The Invisible Enemy)
Abilities and weaknesses[[edit] | [edit source]]
K9 Mark I's photon beam was ineffective against Sontaran space armour. (TV: The Invasion of Time) However, it proved effective against Quarks. (AUDIO: Time in Office) K9 Mark II's photon beam was able to destroy Dalek casings. (COMIC: Doctor Who and the Dogs of Doom) K9 Mark IV's photon beam could disintegrate a swarm of Rakweed spores. (TV: The Gift)
K9 Mark II's blaster ray had an accuracy of 98%. (AUDIO: Ascension)
K9 Mark 2's photon beam was able to heat and cook food, such as a tin of baked beans, although it resulted in the beans bursting out of the tin. When K9 applied this technique to a Korven, white light seem to emerge from its eyes and mouth and its body cracked with white light before finally exploding, leaving its clothes behind. (TV: The Korven) It could deactivate a device such as a Space-Time Manipulator without damaging it. (TV: Oroborus) It could also be turned into a photon spread to disperse gas from a vapour bomb. (TV: The Last Oak Tree)
The Jixen were able to reflect and enhance photon beams. K9 was merely able to halt them with a shot. This ability was later incorporated into Trojan, who was so strong it was able to knock K9 back. (TV: The Eclipse of the Korven)
The Olympians were invulnerable to photon beams; when K9 used them against two Olympians, they were unaffected. (COMIC: The Life Bringer!)
