High above, sitting in the Mondasian sky, Dalek saucers hovered. The primitive cyber cannons bounced harmlessly off their shields. Mondas was burning under the Dalek onslaught. It was fast becoming twisted and marred; a shadow of a shadow of what it once was. Cybermen fell in droves, their deaths being felt across time, ripples in an ever-weakening web. They were losing, and they could do nothing to stop it. Within their ships, the Daleks continued to plot.
"THE PRIMITIVE CYBERMEN ARE PROVING INEFFECTUAL AGAINST DALEK FORCES." rang the metallic voice of a chrome Dalek situated at a view screen.
It watched the massacre unfold. "AS THEY ALWAYS HAVE." bellowed a black Dalek sitting in the centre of the room, the black Dalek watched, calculated, and waited for their inevitable triumph.
Opening a channel, the black Dalek spoke again. "DO NOT RELENT. FULL CYBERMEN EXTERMINATION!"
The comms rang out with a collective "WE OBEY!"
As it turned back to the view screen, the Black Dalek noticed some sort of interference, causing their screen to be filled with static. The screen was soon completely blocked off by the static, with occasional flashes of purple breaking through. Whatever this was, it tripped every sensor the Daleks had, alarms blaring all throughout the ship.
"VIEWSCREEN MALFUNCTION, WE CANNOT SEE." a chrome Dalek screamed.
"WHAT IS HAPPENING?! EXPLAIN! EXPLAIN!" The black Dalek exclaimed. "TEMPORAL DISCHARGE DETECTED."
The sensors indicated that there was a tear in space and time closer to the surface of the planet. Something was trying to get through.
"TIME LORD INTERFERENCE?" questioned the black Dalek.
"NEGATIVE." said the chrome Dalek. "THIS IS SOMETHING NEW."
The sensors pointed to a Mondasian cliff side facility being blasted apart from the inside. The wretched sound of high-powered energy weapons tore through the air, followed by the pathetic cries of the primitive Cybermen.
"Push them back! Do not relent! Do not rele- AUUUUGHHHH!" One of the gas lines within the facility had been ruptured, causing an explosion. The force of it sent the Cyberman flying towards the window. It collided with the glass, breaking through and landing in the snow. Its audio sensors took the time to reconfigure, a high pitched whirring replacing all other sounds. The Cyberman looked down to see that its legs had been blown clean off, black, oil-like fluid seeping from its torso.
Smoke billowed from the destroyed facility, the doors being shot open. From the haze, a Dalek came. It was slightly larger than the rest, a faded white instead of the usual chrome coloring. Instead of a manipulator arm and a blaster, this special Dalek was armed with only a large cannon. The orbs adorning its sides were a dull gold, with its head being devoid of the familiar eyestalk. Through a black, soulless visor, the Special Weapons Dalek took aim.
The Cyberman crawled uselessly away, leaving a slick, black trail in its wake. It inched closer and closer to the edge of the cliff, the Dalek following.
"GaCK! KAH... Arguhh..." the Cyberman choked out as it crawled, the fluid beginning to flow up and out of its mouth and dripping down its rubber-like skin.
"CRAWL!" bellowed the Special Weapons Dalek.
What else could the Cyberman do but obey? As the Cyberman finally reached the edge of the cliff, it looked down at the rest of Mondas. The Daleks were enacting a full-scale genocide, scorching the earth with pulsating beams of energy. They were destroying what little of Mondas there was left. Something welled up deep within the Cyberman. Anger, punctuated by the sting of uselessness. It raised its hand over its face as the Dalek began to charge its cannon.
"Forward!" the high-pitched wail of another Cyberman rang out, prompting the Dalek to turn around. Before it could take any action, the sound of metal slamming into metal cut it off. Throwing all of its considerable weight against the Dalek, the Cybermen managed to push it away. It kept holding on, grappling the Dalek.
"UNHAND ME, YOU WILL BE EXTERMINA-" another Cyberman came rushing forward, bending down and slamming into the base of the Dalek, pushing it back even further.
As a third Cyberman came bounding towards the Dalek, it panicked, firing off its cannon. The shot blew the entire shoulder clean off the Cyberman, yet on it charged, resolute with the fact that it was going to die. The others shared this sentiment fully as the final push was all they needed to send both themselves and the Special Weapons Dalek off the cliff.
The lone Cyberman lay on the ground, continually oozing the oil-like fluid. Dalek Saucers flew overhead, the lights projecting down on the ground that they flew over. It could no longer feel the wind on its skin, nor the heat of the flames as everything it new burned around it.
As its visual and audio sensors began to fail, so too did the rest of its bodily functions. Coolant began flooding into its chest cavity, flooding the primitive emotional inhibitor it was equipped with.
"Please... it.. hurts.." it choked out. The last thing it was able to perceive was what appeared to be a small tear in the sky directly above it. What appeared to be another Cyberman, except entirely more advanced, fell through the sky and landed in front of it.
The new Cyberman, tinged purple and exuding some sort of static, snapped to life and placed its hands on the floor. Its fingers curled, digging up the earth and snow. Its head slowly raised, inching from side to side.
"Mondas." it said, its leg coming forward to push itself up. "Mondas." it said again, lumbering towards the dying Cyberman.
"Among the dead... at the end of days." The static Cyberman reached its hand out towards its dying brother.
A cloud of static seeped out of its fingers, enveloping the other. The dying Cyberman let out a scream as its body twisted and bent under this new power. It was being transformed into a form resembling this new Cyberman. It was being upgraded. Legs, seemingly from nowhere, appeared. The rubber-like skin was replaced with cold, purple steel. The once fallen Cyberman, a reflection of its savior, stood up.
"Time's a maze." it said. "Death to the Daleks." the second Cyberman replied.
"Death to the Daleks!" One of the Cybermen faded from view, seeming to dematerialize, intent on spreading its new upgrade. The other simply looked up, staring right at the Dalek ship.
Aboard the ship, the Supreme Dalek could feel the gaze of the Cyberman, even with all that space between them.
"THIS WILL NOT STAND! KILL THEM! EXTERMINATE! EXTERMINATE!"
The Daleks fired their weapons, bombarding the cliff side. As the ground was torn up around the Cyberman, it vanished.
"FIND THEM!" The upgrade process was fast; fast enough that the Supreme Dalek was growing worried. This was going to spread faster than they could stop it.
"EMERGENCY, OUR SHIELDS HAVE BEEN BREACHED!" The black Dalek could feel the displacements in time and space manifesting behind it.
It whipped around the face its enemy, its manipulator and cannon suddenly being grabbed tightly by one of the new Cybermen. The black Dalek screamed, firing its cannon wildly. It could feel the Cyberman's grip tighten around it, the metal starting to bend.
"EMERGENCY TELEPORT! EMERGENCY TE- AAAAUUUGHH!" The black Dalek screamed at the Cyberman tore its manipulator and cannon out of its casing.
Before any more damage could be done, the black Dalek teleported away, with Cybermen starting to pour in. They spread like the infection they were, overrunning and eventually capturing the ship, killing every Dalek they could find.
They had sustained heavy losses through this victory, even with their newfound power. Their planet had been virtually destroyed. This new strain of Cyberman prepared to unleash itself across the universe, upgrading across time, and eventually destroying the Daleks. This was their first victory.
