A drop here, a drop there (a one-shots/snippet book)

Just Passing Through (Prototype/Undertale)

Alex stared at him blankly for a second, before realizing that the skeleton was waiting for a compliment. He didn't really taste food with his feeder tendrils, it's why he didn't mind consuming infected, but if it will get them out of his hair...

"It's...good." Alex made an honest effort to smile, though he suspected it looked more psychotic than anything.

Papyrus didn't seem to mind though, and Sans was smiling happily.

—————

Alex went through Snowdin Town with no trouble, it seems that most monsters didn't even know what humans looked liked. Thus, he didn't have to deal with them attacking to get his nonexistent soul.

The ones that weren't in Snowdin still used magic bullet patterns as a greeting though, which Alex learned from the Library was a monster tradition. But Alex simply had to dodge and tell them that no, he's not interested in 'greeting' back and go away or else get dusted.

Death glares seem to be effective in making them slink away in fear.

"Hoi! I'm Temmie!"

Nope.

——————

Huh, this female knight actually recognized humans. Too bad Alex isn't one. He helpfully informed her of this, but she just got enraged.

"DON'T LIE TO ME!"

After yet another attempt to what he figured is exposing his soul in a FIGHT like what Toriel talked about, the knight was befuddled and actually listened to him.

"You're not human, but you look like them and came from the surface, right?" The fish monster asked. She had removed her helmet after Alex proved his inhumannes, revealing blue skin and fins at each side of her head. At Alex's "yes", a large grin spread on her face.

"So is it true that people in the Surface fight with giant kickass robots and have fights with giant swords and beams of friendship!?"

The virus frowned. What a strange question...

Alex thought of tanks, of helicopters, and jets. He thought of nuclear bombs that isn't quite a "beam of friendship" but still makes a huge explosion. He answered her question in an affirmative. As for the giant swords...

His arm writhed, unfurling into an eldritch mass of black tendrils and goop, and it reshaped into a huge blade almost as long as he was tall.

"While I'm not human, does this count?"

Needless to say, Undyne was estastic.

——————

He eyed the building with the word LAB above the entrance with distaste, before looking at the pair of knights guarding a different path.

"Where does this lead to? Can I reach the castle that way?" His question sounded more like a demand in his near emotionless voice.

"The elevator is through here, and yes you can." The one on the right answered. "The King's castle is through Hotland, and past the Core. What is your business with the King?"

Alex didn't answer, but his scowl deepened. A lab or an elevator. Both having unpleasant memories connected to them. Growling, he looked up and saw the different floors.

Jump it is.

——————

Alex quickly got through Hotland and the Core in record time, making craters on the floor and kicking down locked metal doors along the way ("Hey! That will take a long time to fix you know!" cried a small rodent monster with a yellow hat) until he reached the King's castle. There was an elevator, but he ignored it and went the long way instead.

The king was humming in the throne room, and when Alex stepped inside he saw that the monster was watering flowers. An odd sight for a king, especially for one who Toriel painted as some heartless killer. Speaking of, he looked like a male bearded version of Toriel, they must've been the same species.

The humming paused when the king noticed the virus' presence, and said, "Oh, hang on. Just let me finish watering these flowers."

Alex rolled his shoulders casually and strode right past the boss monster. "No need. I'll just be going."

"W-wait," Asgore dropped the can, a bit startled. "Where are you going?"

"Out of here."

The king followed after him, "I'm sorry sir, but seven souls are needed to break the barrier! No matter how strong a monster you are, you can't break it by yourself. How about we have some tea instead?"

Alex paid him no mind and found himself in a room of white. There seems to be waves of white going to the end of the room, where it fades before another wave started from behind him. He went deeper in and raised a hand to air, only for a force to resist him.

He backed up.

"Sir–"

And he hit the barrier at great speed, his fists having increased in mass and size for optimal smashing capability. It resisted for a few seconds, but Alex can feel it start to give in. It burned and crackled in white electricity, but he quickly healed with his biomass even as it is burned.

Then he was through.

Asgore gaped and spluttered. "Whu-bu-how?!"

Alex eyed the still unbroken (and crackling) barrier with a frown, then turned around without a word and walked away.

He paused. "Thanks for the...hospitality, I guess." His sister was always on his case about being more sociable.

Extra:

Undyne panted as she supported herself with a spear, but she was grinning widely.

"Hey punk, if you do manage to get through the barrier, maybe you can visit every now and then! Then we'll spar! And you can bring more anime!"

Alex, who wasn't even winded after kicking her ass, blinked at her unsurely. "... Sure?"

And Dana said he can't make friends through fighting people. Shows what she knows.

Extra:

"Alex-! Jesus Christ, where have you been?!"

"..."

"...Alex?"

"I woke up in an underground society of monsters that apparently have been forgotten in history, after humans sealed the monsters under a mountain with a magical barrier made by five wizards. Reality there seems to have taken a bit of game or RPG-like elements, which probably was from the high concentration of magical energy from such a small space. I've met a husband and wife that are anthropomorphic goats, a talking flower, two living skeletons-literally, a reverse mermaid that likes to fight with glowing spears, and a bunch more. Magic exists, monsters are made out of magic, their food is made out of magic, and they sometimes greet each other through magical bullet patterns. Also they can bring out your soul in a fight, which I don't have so that was something."

"...you're not the joking type."

"No, I'm not."

"..."
———————

This is just crack, but the main idea of the barrier that got me into writing this was that there two ways the Barrier acts as a, well, barrier. Magical and Physical.

The magical aspect doesn't work on Alex, basically not noticing him, because he has no soul in this one and no magic. The physical aspect he can brute force through. Others get toasted if they do the same, but Alex can just heal.

Also, I'm wondering whether the barrier stops non-living microscopic organisms.

Also also, I've thought of Flowey getting interested on this new toy that ended up in the Underground, and keeps resetting to find different ways to mess with Alex. But this was supposed to be a one-shot and that will probably make it too long.
