Mankind was on the brink of extinction. Why? Titans, that's why, humanoid giants with a voracious appetite for humans, is there any hope for humanity as the Titans close in on the walls of Shiganshuna! Yes and it comes in the form of Rexx, a Primal, a monstrous beast hell bent on killing titans. Titans meet big ass dinosaur monster.

Thundering Rescue, Survivor of the Fall of Shiganshina

The fall of Shiganshuna had begun and humanity had not a hope to stop it. That was what went through the mind of a young man who looked about 16 years old, as he stared at the chaos and death that was the titan siege. He was a bit tall for his age, standing at 5'11", with burnt-orange shoulder length hair that was up in a ponytail. His eyes were a greenish-yellow and they were sad, staring at the city. His eyes widened in alarm looking where a woman lay trapped under a collapsed home, there was a titan approaching her as she urged the people in front of her to run.

The young man moved from the edge of the wall disappearing from sight moving faster than the human eye can register.

{with the trapped woman}

" Eren, just take Mikasa and run NOW!" The woman screamed with tears running down her cheeks.

"I want to more than anything, but first I need you on your feet," the boy yelled back

"sweetie listen to me, my legs are crushed, even if you could get me out I can't run..." The woman said

"Then I'll carry you...," Eren yelled back frantically trying to get his mother out of the wreckage. The girl, Mikasa, was holding back tears.

"Will you just shut up, for once in your life listen to me, one thing I'm asking you one thing! Mikasa make him!

"You want all three of us to die...Hannis! Take the children and go!"

"Come on Carla, that's not our only option, I'm a soldier specialized in killing titans and saving lives." Hannis said as he ran off to kill the titan, before turning back grabbing mikasa and eren and running.

A flash of blinding light, and the titan along with the entire house, were nothing but a crater smoking, no, not a crater it only appeared to be, it was a hand print fifteen meters wide. A four fingered reptilian clawed hand had smashed the remains of the house as well as the massive boulder, nothing remained. This had all happened, before the flash of light faded, less than half a second.

-Scene change-one year-

"Eren! Mikasa!" Carla screamed as she sat up in a cold sweat. She was laying in a bed in a small cottage inside wall Maria. "but how?"

"Oh good, you're awake, you've been in a coma for a year," there was a young boy with dark orange hair, he was standing in the doorway, "I'm no good for medical treatment, but I figured that a little bit of my blood would help you heal, and keep you from starving before you wake up." He spoke with a smooth voice, he was smiling she noticed his teeth were sharp and pointed, sparkling white.

"Who...are you...how am I alive," she asked him.

"you mean the titan that was about to eat you," he said with a gleam in his eyes, "back in Shiganshuna, as your kids were getting away I killed the titan along with a few of the ones I ran into on the way out, carrying you, don't think that your boy knows you're alive," he said while she stared wide eyed at him. He chuckled and turned to go to the other room. He called back, "if you are hungry I have food, in all honesty I owe you a debt of gratitude for taking care of Misaka all these years."

Carla got out of bed to find her legs had healed and she was very hungry, she walked in to the kitchen and saw a huge meal with enough food for twelve people. She sat down and dug in almost in tears at how good it was, not just because she was REALLY hungry, but it was top quality food.

"Ooohhhh this is so gooooood," she said looking at him gratefully."you never told me your name, or how you know Mikasa?" She said pointing a fork at him.

"I was there when she was born as well as for her mother's birth, a sort of family guardian, which I failed miserably at." He said before holding his head in his hands.

"That doesn't make sense, you look so young...," she asked confused.

"My name is Rexx and I am seventy-three years old...yeah I don't look it, around for awhile now but I never thought I'd see something like that big S.O.B. that wrecked the wall."

"So Eren and Mikasa...they're alive?", she asked unsure.

"Well we could go find them but I don't know how long it will take we are a very long way from the city of Trosk, but there are a lot of titans between here and there." He looked at her like he was testing her resolve to see her kids again.

"Can we make it?" she asked him.

"I'd honestly be surprised if we didn't make the trip, titans don't like to come near me, I think they don't like how I smell." He said rather uninterested, Rexx could make the trip in a few hours at top speed but that would be bad for Carla. He was sure that the wall defenses would open fire on a thirty meter tall giant lizard, that kinda called for freaking out.

"Then we go, as soon as possible." She said with a fire in her eyes, she was going to get back to her family.

-five years after Shiganshuna fell-

"What is that...hey I think there are two people out there, in front of the gate," a garrison soldier asked his comrades.
"There is no way...wow...how the hell did they make it here." The other one said before they both stared in shock as one of the people walked up to the gate and lifted it up and the two slipped inside. The gate weighed more than even a titan could lift beig around ten tons of brick and mortar, needing a powerful winch to hoist the gate.

Rexx had lifted the gate with very little effort at all. His strength was FAR beyond that of a titans, his speed, he could easily break the speed of sound.

"You saw that, right." one soldier asked.

"Nope!" another said shaking his head, wanting nothing to do with someone that strong.

"No, I saw nothing." the last one denied, knowing that anyone that strong would be more terrifying than the titans.

"Come on...probably better we don't go down there, huh." the first one conceded, wanting to live longer.

-with Rexx and Carla Jeager-

"You could have knocked, you know that right," Carla told him with a smirk.

"This is easier, they would ask questions that I don't think I can answer," Rex said with a shrug.

"...four years and we finally get to Trost." Carla said after a short silence.

Rexx and Carla walked, through the crowded streets of the district that held the refugees, this was the first place they would look for Eren and Mikasa. It made sense, at least it would make sense if Eren hadn't been hell bent on killing every titan in which case he probably joined the to military. people gave the pair strange looks, possibly because of the way they dressed, Rexx wore his brown cloak, he had his sword, Tyrant Fang, a crude looking five foot blade, made of a energy infused steel making it extremely strong, yet REALLY heavy. The blade was an inch thick, with the appearance of a Bowie knife, the handle had bandaging and slanted guard. The total weight was around 400lbs. He was a strange sight.

Carla was now at this point much stronger than most humans, with an unexpected change to her appearance. Apparently Rexx's blood that was in her veins, it had fully fused. That meant she was a half-blood now, half human, half...whatever she was. Rexx had only heard stories of this happening, now he was one of those stories. Her hair was jet black, rather than a dark brown, her eyes had a reddish out line to her irises. Physically she had more muscle tone, yet still a feminine figure.

She was wearing an outfit that Rexx had made for her, she wore deerskin moccasins and deerskin pants, the blouse, was a simple white top. He didn't have much to work with, but Carla appreciated the clothes all the same since her old clothes were not suited to the environment, they were torn and dirty too.

"You know he might have joined the military," Rexx told her as they walked into a open square. Carla sighed, she knew it was a long shot, and since Eren still thought she was dead, it wasn't as though he would give up on joining the scouts. Knowing Mikasa, she'll be with him.

The search was almost over, but a battle was on the horizon.
