Author's Note: I do not any of the characters that are from the Mega man series, but I own all of my original robot masters. Most the lore has been taken from Wikipedia, so please do not come after me for any sort of inconsistencies.
Mega Man 12: The Final Plot of Wily
Chapter 3: Drowned Man Battle
Rock stepped through the second door of the small room he had entered, not knowing what to expect. He did expect the room to be empty at first, and he did expect there to be a little water on the floor of the room. What he did not expect, however, was the corroded, ruined exterior shell of the robot master that leapt from the water, eyes covered with black river weeds and tarnished interior skeletal frame showing through where the outside had been eaten through, and a pike on its left arm, one that matched the condition of the rest of the body. The ramshackle automaton looked at him and what was left of the eyes shown with a burning hatred.
"you did this to me"
The mouthpiece of the robot did not move when it spoke, and it's voice haunted Rock. To Rock, the voice sounded distant, liquid and without gender, somewhat akin to what one would imagine someone calling out while underwater. He shuddered and turned to the broken husk of what appeared to once be a robot designed to pick up trash and keep the riverfront clean.
"I did not do this to you, I am being framed by Doctor Wily. Look...I am not going to hurt you."
"liar"
The robot jumped up, enraged, and started glowing red. Rock knew this meant a more powerful attack was coming, and was just able to jump out of the way as a hail of rusted spikes landed in the room. Rock looked at his attacker and sighed. He knew what it meant if he was going to be attacked by the robot. He was going to have to talk the situation down, or attack the poor garbage collector in self defense.
"I'm not going to fight you unless you give me a reason to."
The robot laughed and jumped as a series of explosions disintegrated the ground under Rock's feet, plunging him into water that was brown and rust colored. It wasn't hurting him, but it made him move slower and float higher when he jumped. The Drowned Man sank as he jumped into the water and landed next to Rock.
"you did this to me i have every reason to do fight you"
"Then you leave me no choice"
Rock curled his hand into a fist and jumped as the Drowned Man shot a spike at him, aiming for his helmet. The spike narrowly avoided his feet, and in response, Rock shot a couple of bullets from his mega buster into the robot. He frowned when he realized his bullets were hitting exposed underwiring of the broken robot and causing even more damage to the already broken robot.
The additional damage that Rock was doing with his mega buster only seemed to make the oxidized golem of metal and wire only fight harder to destroy him. More spikes were shot as the robot activated the Power Gear, causing Rock to have to dodge more. The water also got rustier as more pieces of armor were knocked off and started sinking down. Rock was not trying to harm the robot any further, and saw when it was about to give up and explode.
"Stop attacking me and I'll stop shooting you."
The broken, almost robot looked at its attacker, and saw something he did not expect. There were bright blue eyes staring out from the helmet. The one who threw it into the water and brutalized him had red eyes. This robot spoke gently, and the other one had shouted at it. His power was shutting down, and he only had a few moments left.
"take this..."
The robot gave Rock his last functioning part, his trash collecting spike, before his eyes closed and he exploded into metal pieces. Rock had to use his signature slide to avoid being hit by shrapnel. He was looking at the piece when the water drained and he saw himself, but with blood red eyes.
"WHO ARE YOU? WHY ARE YOU DOING THIS?"
The duplicate laughed and vanished into a beam of blue light, dropping a piece of paper with the word "theater district" written on it. Rock frowned and followed the light to the district where it was heading.
