A giant golden book with a green hourglass symbol appeared from the empty space as it opened up its pages...again.

The Forgotten Ben's: Chapter eleven, Corrodium Nightmare.

Xxxxxxx

-USA, South Carolina, Dairyville, Maplewood Farm Camp-

"Ugh, stupid farm. Coming here was a bad idea." Ben grumbled as he and Gwen were busy doing farm work, more specifically cleaning the chicken coop in the middle of the night.

"Not my idea of fun either ya know." Gwen grumbled before noticing a bolt of purple lighting in the distance and recalled how Todd was attacked by a mummy under a bolt of purple lightning.

"I know that look." he smirked. "You want to ditch this and kick some mummy butt."

"Considering the weird lightning? Yeah, that's a no brainer." Gwen smirked before they ran towards the hill, and saw some dark purple mutant cows, with thick spines and sharp dagger-like teeth, in the distance.

"Moooo."

"Um...ok, that's just wrong."

"That's putting it mildly." Ben said before turning into Four Arms as the cows charged at him, with a bandaged figure walking close by, looking for something.

"Mooooo!"

"Down bessie! Down!" he yelled as he grappled with one with two arms, while using his other arms to try and keep the second one from biting at his stomach.

"Moooooo!"

He threw them to the side before seeing the mummy walking off. "Hey, get back here!"

That was when a cow charged at him, only for it to fall face first on the ground, breathing heavily as Gwen saw Max running over to them.

"Kids! What's going on?"

"We don't know!" Four Arms grunted before changing back. "But these cows aren't looking so hot."

Max took out a scanner from his pockets and used it on the cow. "This bovine is highly contaminated by corrodium radiation. Strange."

"Why?"

"Corrodium isn't natural to this planet."

"What exactly is it?"

"A rare and highly radioactive material that can power an entire city for years, but-"

"Oh I get it." Ben said before running after the mummy. "I just have to get that rock first."

"Ben wait! It's too dangerous!"

But it was too late as he ran in the direction of the alien.

(Later)

-Digby Dairy-

Ben, now at the ice cream factory, grumbled while admitting to himself that running after the Mummy without backup was a stupid move but he would get the chance to stop that alien without help this time. "Well time to get that rock, and I know who to use."

FLASH!

He looked at himself while now in the form of XLR8. "Damn it! I was going for Diamondhead, not him."

As he regained his composure, he started to vibrate his hands at super speeds and began to drill into the concrete and earth.

"Ow ow ow ow ow ow ow OW! Ok this actually hurts!" he yelled in pain as while he was breaking through solid concrete and soil, it still hurt him due to his weak physical strength compared to his other forms. "Come on come on! Where are you, corrodium?!"

BAM!

And as if on cue, a massive dark purple crystal the size of a large dog, shone in the dark factory as it began a terrible change upon the dinosaurian alien.

(With Gwen and Max)

Both ran past the guard, who was still asleep at his post, while currently looking for Ben and the Mummy.

"I can't believe that idiot just ran off like that! Is he trying to get himself killed?" Gwen yelled in frustration. "That stupid dweeb!"

"We need to find him and avoid being exposed to the corrodium, or else we'll be mutated like those cows." Max said as they raced into the factory, but not before noticing the Mummy, now torn to shreds and lifeless, right near the entrance to the storage tanks.

"Is that..."

"The Mummy, yes."

"But what could've done that?"

"Must have been Ben."

"Wait what?! But Ben isn't that-" Gwen said in shock before seeing something in the middle of the room, just as Max placed a light green and black hazmat suit with a red orb in the center of her chest, on her and himself.

"These suits will protect us from the corrodium's radiation." Max said before they entered the room, and saw that no one was there. "Now we just need to find Ben."

Gwen felt a little uneasy as they looked around the area, the corrodium still in the ground as a pair of purple eyes looked at them from the shadows.

"Ben? You around here?"

Silence.

"Dweeb? Are you in here?"

Silence.

"Ben?" Gwen called out before hearing a wheezing sound right behind her.

"Ah….ah….ah….Gwen…."

Her head slowly turned around and saw something right behind her in the shadows.

A pair of purple eyes.

"B-Ben?" she called out, feeling that something was off.

"Ah….ah….ah….."

She moved back as Max looked at the eyes, seeing a figure walking out of the darkness.

That being a tall dark purple and black humanoid that seemed to twist near the torso and formed a hunched appearance, with long spindly legs dotted with barbed feet that curved outwards and extended inwards like talons, a single small left arm with a large claw that dripped a concrete eating liquid, misshapen fangs that curved outwards and took the appearance of mandibles, large curved horns that went through it's shoulders and around the hips, small purple eyes that were placed above and below the shrunken nostrils that used to be a nose, and had a giant gray right arm that dragged across the ground and was covered in ten long claws that seemed to twitch every few seconds.

"Ah….ah…..ah…." it wheezed out before suddenly sending a large black reptilian-like tongue at the corrodium and placed it in a small cavity on it's right breast area, long tentacles of black veins holding the mineral in place like a bear trap. "Ah….mine…."

Gwen stepped back in fear as Max was horrified at the creature's appearance.

The figure wheezed before the right arm glowed and it was covered in a bright light that blinded the two humans.

"Ah!"

SWISH!

Max went wide eyed as his suit was destroyed by something sharp as he could feel the radiation hitting every part of his cells, but he turned and saw a large dark purple ape-like creature the size of a bear, with a long spiked tail that went around its body like a snake while a single eyeball sprouted from the tip, sharp dagger-like claws, ten foot long quills along it's back laced with a purple liquid, thick dark black stripes on its shoulders and back that seemed to be bioluminescent, four long fangs that erupted from it's snake-like head and overlapped near the sides of its face, eight gill-like nostrils on the sides of its neck that seemed to contain a million tiny eyes, a long barbed tongue the size of a full grown human being, and had a thick gray upper right limb with multiples quills dotting it's shoulder like a decorative guard, looming next to him with a smirk.

"Grrr…" it growled as Gwen's eyes returned to normal but saw to her horror the giant monster and a large bloated worm-like humanoid with black eyes, long twisted spikes where it's arms and legs were supposed to be, and giant tentacles from its mouth like appendage, the broken remains of the hazmat suit still on top of it.

"G-Grandpa!"

"Grugle…."

"Grrr…." the giant beast growled before charging at Gwen, who was in so much fright that she couldn't say or even think of a spell.

"Exciase!" called out a voice from out of nowhere as a dark purple aura covered Gwen's body.

SWISH!

But it wasn't fast enough as the large creature slashed at her right arm, destroying the suit and causing it to mutate as she finally vanished.

(Elsewhere)

And appeared in a small castle where she screamed in pain, her right arm now transforming into a dark purple and pink claw with ten eyeballs all over it, but before it could spread to her arm a dark gold talisman with several runes flew towards the arm and wrapped around it.

"Thracius minimus."

The talisman glowed bright pink as it covered the arm in a small crystalline structure that instantly fused to her arm and became covered in runes, the talisman now embedded to her shoulder.

"What…" Gwen got out as the pain subsided, but felt different, like a part of herself was corrupted into something unnatural.

"Looks like my uncle's magic ball was correct, for once." spoke Charmcaster as she walked towards Gwen. "You need my help, and while I hate you for taking my book, there is a threat even greater than myself, and I require your assistance."

Gwen looked at her in confusion as she felt like this was just the beginning of a long nightmare. 'Just what is going on?!'

Name/Designation Title: Benjamin Kirby Tennyson (Corrodium Ben- CBen)

Age: 10

Affiliation: Bad

Dimension: 00012- 9912 CB10

Trix/Abilities: Omnitrix (broken down into a metallic limb), corrodium based biology, normal intelligence.

Aliens used: Four Arms, XLR8, Wildmutt (Mutated).

Bio: This particular Ben is a sad one as unlike Prime Ben, who's omnitrix's safety feature was intact and was in a suit after becoming Diamondhead, this one had it's safety feature broken beyond repair from overuse and was mutated by the massive meteor in the process. The radiation caused the omnitrix to turn into a limb that still allows for the transformation of alien species, but in a mutated form, as well as keeping his intelligence, but is now similar to a virus, trying to infect and corrupt others to his cause. His first victims were the Mummy, who was ripped apart by the creature, Max, mutated into a monster, and Gwen, who was spirited away by Charmcaster to stop Ben's infection of all organic life, but gained a mutated arm of mana in the process.
