Exactly the true power is often up to debate but it appears that this is often described in Nazi research as "Immortality", unable to die, invincibility or other factors surrounding losing the capacity to die in some way or another.
The larger part of this research was actually legitimately based; certain doses of chemical compounds to aid blood flow in aging people. First concepts that are now used in today's transplant surgery, grafting, ointments that renewed skin, antibodies to various diseases, and fitness/dieting research.
However, one set of crates discovered in Hamburg in 1999 went way off of this research style. This stuff cross-bred the Occult experiments and immortality research.
"Childen, do you mind showing yourself ?" Slenderman asked, looking towards the voices.
Without an actual answer, and a few moments of hesitation a two young girls came into view. The older one looked about fourteen or maybe older. It was hard to tell because of her height, or lack of so. She was deathly pale with (h/l), (h/c) hair that was pulled into two pigtails tied off with ribbons with flower clips. Her (f/c)kimono was stained with blood from her neck. It looked like her throat had been slit, or her head cut off with a blunt object because the cut wasn't exactly precise. Blood still leaked from her neck causing her kimono to still be blood soaked. It ran down her body and created a small puddle on the floor and around her feet. In her arms she clutched a purple and white stitched bunny that had a bandage wrapped around its neck.
Her feet were bare and littered with scratches.
The two girls shared a look before the ravenette stepped forward. Both of them bowed, although the younger one was the only one to talk.
"Konnichiwa, I'm Ichigo. This is (Y/n)." She motioned to her (H/c)-ette friend, who blushed and held her plush tighter.
"It'd be better if you didn't enter here." Ichigo seriously stated, looking towards the door. (Y/n) nodded, moving towards the group of men slightly, her small feet making no sound.
"Why's that ?" Slenderman asked gently, trying not to scare the girls off, since they looked frightened enough already. BEN had been vague on the information that he'd given them. The two girls looked at each other for a few moments before Ichigo nodded at (Y/n).
"I-it's dangerous..." Shyly mumbled the (h/c)-ette, squeezing her plush tightly. Ichigo nodded in agreement and then motioned to (Y/n).
"(Y/n) can show you the way out of the forest. It tends to have a mind of it's own." (Y/n) shot a look of disbelief at Ichigo, who just smiled and patted her arm before disappearing.
"What ? But, I wanted to see what's inside that door." Whined BEN, flailing his arms slightly.
The door gave off an aura that just screamed 'threatening.' The smell of death and decay was strong, and so were the blood puddles and splatters. Now that they get a close look at (Y/n), they can understand why they were so prominent.
"Follow me, onegaishimasu (Please)." Mumbled the (H/c)-ette as she began to walk-er-float down the hall, leaving a trail of blood.
"What happened to your neck ?" Jeff inquired rudely, getting a smack on the head from Slenderman.
"Jeffery, don't be rude." Slenderman scolded.
"Don't call me that!" Jeff glared, or the best he could with no eyelids, as he tried his best to scowl.
"I-it's f-fine..." Mumbled (Y/n)softly, staring at the ground.
"D-during the whole...N-Nazi e-experiments I-I rebelled. T-they d-decapitated me..." (Y/n) muttered as she squeezed her stuffed bunny tightly.
"T-that's so sad..." Hoodie said, frowning on the other side of his already frowning mask.
"I'm sorry, child." Slenderman sympathetically looked at her.
They made it out of the building, the sky was crying, causing everything to be wrapped a blanket of cool rain. It splashed on to the ground, creating small puddles the grass swallowed. Thunder clapped loudly as lightning flashed frequently.
"If y-you follow t-that trail, i-it'll ta-take you ba-back to the m-main road.." (Y/n) muttered softly, looking at them.
"T-though...I d-doubt you sho-should go now..." She motioned to the rain.
"Children, please introduce yourselves to the young lady." Slenderman said, 'looking' at his 'kids.'
