"How about one where dan-o grows fangs as part of his ghost self maturing… How will everyone react in school when Danny suddenly looks like a vampire?" - "Guest" (a Guest) on this site
(Supplemented by "danphanwritingprompts" on Tumblr: "When you walk the fine line of being both dead and alive, it shouldn't be much of a shocker to find out that it renders you immortal to aging and natural death.")

"That's the fifth one this week, right?" asked Sam.
"Yeah…" Danny grunted.
"They're really that fast?" asked Tucker.
"Seems like it," Danny grumbled.
"Jeez… That's rough, man."

For the past couple weeks, random citizens of Amity Park had been attacked by what they described as a "vampire ghost." And every time Danny's ghost sense would go off, he'd go to catch it - but it would be gone by the time he got there.
And it wasn't like he had to stall to come up with an excuse to leave anymore; he'd long since decided to play the "quiet, no-trouble teen" to avoid unnecessary questions. (And besides, everyone was used to him rushing out of rooms without warning by now. It was "normal.")

"And now, not only do I have to deal with a vampire, I have to deal with looking like one, too!"
"Woah! Your fangs came in?!"
Walking backwards now, Sam leaned around in front of him, staring at his mouth. He opened it obligingly.
"Awesome…!"
Danny closed his mouth with a snap. "Glad you're enjoying it."

She returned to walking on Danny's right.
"Come on. How can you expect me NOT to love it? But that does make me wonder - weren't they only supposed to show up in-"
"-In my ghost form? Yeah, they were. And none of the ghosts know what's going on, either. I even asked Vlad. And y'know what he said?"
He wrinkled his nose and gave his best Vlad impression: "'It's probably because your ghost and human halves are more connected and balanced than my own. Why, you might even be immortal, my boy!'"
Sam and Tuck's eyes widened.
"Duuuude… That. Would. Be. -"
"I swear, if you say 'awesome,' I'm not playing Doomed with you for a month."
"But wouldn't it!?"
"Maybe, but I'm not exactly planning on checking!"

"Well, look at the bright side," Sam interjected. "At least the fangs aren't that noticeable."
Danny raised an eyebrow at her.
"They really aren't!" said Tucker, patting Danny on the shoulder.
"If you guys are sure." He sighed, "…Not that there's anything I could do about it anyway. I tried filing them down and they just came back after I transformed."
Leaning back, he put his hands behind his head and looked at the sky. "Whatever. Just one more thing I have deal with."

...

Alex walked into the office, put the slip of paper in their hand in the tray, and walked right back out. It was a doctor's note for their cousin Avery. They'd been attacked by the vampire and, because of their anemia, Avery had had to stay home for the day.
Everyone kept saying Phantom would catch this "ghost" soon, but Alex knew better. They'd lived in Amity their whole lives. Ghosts don't suck blood. Not even so-called "vampire ghosts!"
And now… Alex could do something about it!

They'd noticed it during lunch: The boy with the fangs. It was odd, because no one else seemed to care. They'd pointed out the boy to one of their upper-classmen friends, who just shrugged and said "The Fentons are weird."
So they'd asked around more - but kept getting the same answers: Sure, he got injured a lot. Sure, he healed fast. Sure, he didn't really talk to anyone anymore. Sure, he ran off randomly sometimes. Sure, he didn't look any different in his senior year than he did as a freshman. And sure, his canine teeth looked longer than normal now.
But, hey. "The Fentons are weird."

So it was up to Alex.

Sunlight didn't affect him, clearly. So they tried the most inconspicuous thing first: They dumped a bottle of holy water on him.
… Nothing happened.
Next they tried putting garlic in his food during lunch. It took a few days, but they knew a ghost attack would happen. And when it did, they used the distraction.
… But he ate it just fine.

Alex was almost ready to admit they were wrong - but they had one more trick up their sleeves.
Alex took the sharp, needle-like end of one of their spiral notebooks - and twisted it out just a centimeter. And when they passed Danny in the hallway, they managed to scratch his arm.
He flinched, hissed, and quickly tried to hide it - but too late. Alex kept walking, but they saw it.
His arm healed almost immediately.

So when Avery was attacked again, and this time… sent to the hospital…
Alex knew what they had to do.

...

Danny might not have been the brightest student, but he'd gotten pretty good instincts after three years of fighting ghosts. He'd had to.
So of course he'd noticed the freshman following him around.

He wasn't sure what their problem was with him, but he figured it was just a case of a new person being weirded-out by "that Fenton kid." He didn't expect them to stop staring at him for while - he even expected they might prank him again, like with the water-bottle.
But he DEFINITELY wasn't expecting to get freaking stabbed through the heart with a wooden stake!

… But when it didn't kill him…
He did the only thing he could think of: called Sam and Tuck.
"So, uh… Good news and bad news.
"The good news is: It looks like I AM immortal. Bad news:

"I think I just scarred a Freshman for life."

This is part of my "One-Shot Wednesday" project - I'm trying to write a one-shot every week that other people have requested! Original Requests one week, and Fanfic Requests the next.
(Only Fanfic OSWs are posted on this site, however.)

To vote for the next OSW, go to my Tumblr ("CiestessDE"), Twitter ("Ciestess"), or my website (crossroadofinfinity. com) to find the current poll!

While I will try to keep track of all the requests I receive regardless of how they're sent, you should send Fanfic Requests through the pinned tweet on my Twitter ("Ciestess"), and Original Requests through either my email (CiestessDE *at* gmail . com) or my P atreon (if you're a patron) if you want to make sure I see them.

Just about everything goes - I'll tell you if there's a problem. But if you want to know more about how they work, you can read about Original OSWs on my website (crossroadofinfinity. "com/" 2019/07/07/how-it-works/), and Fanfic OSWs in my profile.

So please send me ALL the ideas! I will make sure to recognize whoever's idea/request it was in the work – just ask if you want to remain anonymous.

And if you liked this, please SHARE it!
