It was dark, so dark, moans of pain entered Eren's ears as he slowly sunk into the foul smelling juices of the titan's gut.
"I've been eaten alive" though Eren, the thoughts flying tumultuously through his mind.
Everything hurt, his back, his head and his eyes. He could feel the stumps where his arm and leg used to be throbbing with agony as the bile seared the exposed flesh.
"I'm going to die, but at least Armin is safe."
This small mercy eased the panic as he slowly drifted down into the sludge, let his mind ease the passing of his body.
"Promise me you'll come back alive.
Eren eyes snapped open just as his neck began to submerge.
"I promised her, I swore I would come back."
He flashed back to where Armin was sitting on the stairs, crying, but trying to hard to stay silent.
"I swear Armin I will kill every last titan for what they did."
Eren remembered the moment where the Smiling Titan ate his mother, his tears burning his face, Hannes panting, the smell of fear, Mikasa holding him tightly.
The entire 104th listening to him as he declared he would slaughter every titan, his solemn vow to destroy humanities enemies as long he was alive.
"I'M STILL ALIVE YOU SON OF A BITCH!" Eren screamed, "I SWORE TO EVERYONE, TO ARMIN, TO MIKASA!"
Eren still holding his blade, a solider, a consummate survivor, the weapon was his life-line, even in death his hand would never drop his weapon.
"I SWORE TO END YOU" Eren could feel his eyes even in the darkness widening and the grin which his only sported when thinking of titans.
"I WILL KILL YOU ALL!"
The ooze bound his tightly but Eren will to live was second only to his will to kill, he struggled to straighten and with a scream his lunged and lunged until his connected with the wall of the titans stomach.
The blade bounced back, Eren swung wildly, again and again every time a failure but each time he failed his rage grew until his throat was raw.
"I WILL NOT BE EATEN, I WILL KILL YOU ALL!"
Suddenly a shaft of light and screaming assaulted Eren from above. He looked up and saw the titan's throat.
He must be eating someone. It could be Armin, Mikasa, Jean it could be my friends!
"ARGH" Launching himself as hard as he could, Eren got his manoeuvre gear free of the slime and using the one cable he could aimed it at the roof of the titan's throat.
A sickening crunch followed by an abrupt end to the screaming and darkness once again, Eren soul hardened as his pure resolve and will pushed the trigger, followed by the sound of squelching as the grapple stuck in.
Screaming again Eren reeled himself up at top speed, crashing into the flesh and kicking of the back of the throat. Flying across the soft flesh of what Eren could only assume was the tongue he was flung into the titan's teeth. Seeing light through the cracks drove his mad resolve, screaming and panting Eren jammed his blade into the titan's gum.
The roar was deafening and as the mouth opened, Eren took his chance, seeing nothing but blinding whiteness he fired his cable and hearing that tell-tale crack, he flew from the titan's mouth.

Staring blearily at the tiled rooftops, Eren slowly came too. His head now at the forefront of his pain management, he saw he had gone headfirst into a chimney. Dazed and concussed he saw the titan he just escaped two streets away fumbling for a way around to eat him.
Eren knowing he had to stay calm tried to stand himself but just ended up flopping from side to side. He was confused until he looked down and his senses returned in full force. He was trying to push himself up with a stump. His entire left forearm was gone.
His heartbeat went overdrive and the panic set in. He was going to die, Eren tried to stand again using his fist clutching the blade and promptly rolled down the roof nearly falling to his death. Grabbing the gutter at the last second Eren was for a second time completely fazed by this. He has stood up normally for years, surely his arm wouldn't stop him.
The memories slowly came back, everything, Thomas being eaten, his mad dash to avenge him and then…
"Oh god" Eren mumbled, the horror setting in yet again.
Even hanging, minutes from death Eren couldn't bring himself to look down, he already knew it but didn't want to believe it. He knew his left leg was gone as well.
"God I'm crippled, I can't fight, I'm nothing!" Eren yelled, his tears mixed with the blood running down his face.
The sobs choked him and he actually thought about letting go of the rooftop, just to end this nightmare.
He would recall later in life that it wasn't resolve or will that made him survive, but as he hung there crying like he did 5 years ago the thing that kept him going wasn't love or dedication but pure, unadulterated, unbridled rage.
A roar brought him back to reality, the beared titan had found its way to his street and was closing in on his rooftop.
Eren's grin flew onto his face as he let go of the roof top
"Hey asshole, your kinda stupid for actually coming back to me" he said falling through the sky, "because even if there's only half of me left."
Activating his cable it struck low down past the titan and he flew down sliding the ground hard. Kicking up the cable returned and he swung about firing it at the titans exposed neck. With a huge burst of gas he rocketed into the titan's neck gouging his blade in deeply and wrenching it across, brutally severing the titan's life.
"It's still more than enough to kill filth like you!" Eren screaming at the top of his lungs, relishing his first titan kill.

With a sigh the tian crashed to the ground flinging Eren down hard. It was enough to crack a rib or two and he blacked out for a few moments.
Lying there staring at the sky after coming back he wondered why he hadn't bled out. Thinking like Armin he assumed the titan's stomach was acidic enough to cauterize the open flesh but just tenderise the rest.
"I feel really heavy on one side, this is totally gonna suck" Eren lamented beginning to feel pretty sorry for himself.
Suddenly feeling it was hard to breathe Eren rolled quickly to the side and coughed up some blood.
"Shit, even if the arm and leg don't kill me everything else soon will."
Pushing up onto his one knee leaning his arm across the ground like a bar he was able to prop himself up some. The smell of burning titan kept his spirits up as he forced himself in the air and balanced on his one good leg. Wobbling, he pushed his blade to the ground and leaned to the right so he wouldn't fall over.
"I look like some retarded scarecrow for scaring kids" Eren chuckled making his lungs burn like fire.
"Okay need to get to a rooftop" he surmised, "if I pass out down here I'm screwed but at least up there someone could find me."
Using his manoeuvre gear his launched onto the nearest rooftop, clipping his foot on the way up. Cursing as he fell over and planted into the tiles, he wondered if it would be even possible to get out of here using just one cable, there was no balance and even less ability to use his gears name sake.
"Okay just got to focus and re-group" Eren mumbled, not noticed his voice was starting to slur.
Though his did notice his vision getting dimmer. Blood loss was taking its toll and without treatment Eren would die.
"First thing's first got to get back over the wall and survive, just have to sur…"
Eren cut himself short as in his field of vision he saw an abnormal clutching a building and climbing in a weird fashion. His vision which was blurry became stark and focused, tinging with red Eren said one word before he rushed the titan's position.
"Thomas."

Author's Note: Don't get me wrong I adore Shingeki no Kyojin's epic universe and diverse set or characters but I remember when I first watching the anime with my mates and we screamed "Holy shit the main character got taken out." We were blown away by the courage and change of pace this brought to the show. Then super-power titan comes out and we are going "Oh my god this is so epic an abnormal that kills titans what's next?" then it turned out to be Eren and it sort of killed it for me. I still loved it but always wondered if you wanted Eren to survive why not let him use his mad skills and epic rage moments to dictate his survival odds.
So that's what inspired this to be written. Hope you enjoy it friends.
