Apparently the first draft for Hot Fuzz included a love interest for Nicholas named Victoria. Though she was cut from subsequent drafts a lot of her dialog was given to Danny - often without any changes.
Jack Frost & Danny Phantom, "Well one of us is gonna have to change."
If North had known the catch–that when Jack asked, “Can I invite a friend to the party?” he’d meant, “Can I invite a human to the party?”–he probably would’ve said No.
“What are you talking about?” Jack laughed, face scrunching up in amusement, crossing his arms. He looked a bit out of place without his staff (it was a masquerade party, and he’d come dressed in the black and white garb of a popular American superhero named Phantom), but Jack’s eyes still shone with the familiar glint of a trickster. “Danny’s not human. Not entirely.”
“Ah, but there is the issue, my friend. Part human is still human.” North explained, casting a wary glance across the room. The boy in question chatted animatedly with Tooth, Bunny, Coatlquetzal, and the Groundhog. Danny himself had a blue hoodie, brown pants, and a certain crooked staff in his hands. North tried to shake off the uncanny resemblance; if Danny only had a white wig, he’d be identical to Jack Frost.
Danny wasn’t having any trouble seeing the guests, though, despite being well past the age of most believers. North wasn’t sure if the boy was a medium or had nonhuman heritage, but it didn’t matter. It was still dangerous.
“There are many spirits here who would take advantage of a human,” North pointed out. “Not at my party, perhaps. But after.”
“Danny? No. he can take care of himself.” Jack said.
North raised a skeptical eyebrow, so Jack called over, “Hey Danny! Come meet Santa.”
From across the room, Danny and Jack shared a knowing glance, and briefly North wondered what was going on between the two. He didn’t have much time to ponder it, though, as the teen tactfully broke away from his conversation and ambled over with a smile.
Danny offered a hand to shake. “Nice to meet you, North, Jack’s told me a lot about you. And… my dad’s a big fan,” he admitted sheepishly.
North shook the offered hand, casting a confused glance to Jack, who just grinned, eyes sparkling. “So North seems to think,” Jack started out before North could get a word in edgewise, “That you’re human.”
A pause, and instantly, Danny grinned too. “I knew that whole ‘watching you 24 hours a day’ thing was BS.” He turned to North, eyes dancing with such amusement that North irrationally wondered if he was Jack’s twin. “Are you asking for a demonstration, then?”
North blinked. “Demonstration?”
Grinning, Jack stole his staff, and Danny stepped back, hands clenched at his side.
And then a white ring appeared around the teenager’s waist.
Heads turned as the bright flash grew, parting over Danny’s form to completely change his appearance. The hoodie and pants transformed into black and white hazmat; Danny’s black hair inverted to white. In an instant, the human was gone, replaced by Phantom, ghost superhero of legend.
North’s jaw dropped. Jack, behind him, laughed.
“See? What did I tell you? That was priceless!” Jack sauntered over to lean an elbow on Danny’s shoulder. North blinked. Now Jack and his guest were both wearing the same outfit, and except for the height difference and one’s green glowing eyes, the two looked identical.
Danny poked Jack in the chest. “Yeah, but now one of us is gonna have to change.”
“Bloody hell,” whispered Bunny from somewhere behind North, echoing his thoughts. “I can barely handle one Jack Frost–what’re we gonna do with two?”
“Try focusing on your core and twisting the ice out. That’s how I make ice spikes, and once you got them just right you can chuck ‘em.” Jack instructed, placing his hands just over Danny’s elbows and lightly pushing them into the correct posture.
“It’s not fuckin’ workin’, man.”
Jack only smiled. “I have like, three hundred years of experience on you. It’s alright if-”
A knife-shaped shrapnel of ice barely nicked the outer shell of Jack’s ear. Danny’s eyebrows raised.
“Oh, it’s on!” Jack formed a huge snowball in his hands and launched it at the ghost, cackling madly. Danny went intangible and laughed at Jack’s irritated look as the snowball hit a wall forty feet away and scattered the snow into the street below.
“No ghost powers! It’s not fair.” Jack stuck out his tongue and cross his arms.
“First, close your eyes.”
Jack rolled his eyes but closed them anyway, and didn’t shiver when Danny’s cold presence shifted closer to him.
A gentle kiss on his eyelid, a small gasp, and then his eyes shooting open when he felt a fuck ton of snow hit his face.
“IT IS SO ON, PHANTOM!”
Danny can fly fast, but nothing can rival the wind that Jack harnessed to slingshot him at max speed, fifteen snowballs at hand and ready to fire.
Later that day the citizens of Amity Park were treated to an impromptu snow day by the two dead white haired anime weebs and they were very confused.
Green Arrow, Green Lantern, and the Flash teamed up to dress Phantom up as Jack Frost for Halloween. They even had Jack’s stick ready. They then made Phantom use his ice powers enough to make the teen’s eyes blue to complete the look. Eventually Phantom got roped into going to random towns. There, Phantom would stay invisible while the other heroes (while in their own Halloween costumes) would go ask kids if they believed in Jack Frost. When the kids say yes, Phantom would drop his invisibility and fly in front of the kids. Which makes the kids squeal in pure joy. Phantom would create snowballs in order for everyone to have a snowball fight. To say the least, it was a good Halloween.
The first time Danny blew his ghost form to smithereens, Tucker was understandably terrified. The ghost fight had been progressing as normal (meaning Danny dishing out more bad puns and jokes than actual damage to his opponent) when there had been a huge blast of light and energy - and Danny had vanished. Although Tucker had canvassed the area all night, he found nothing more than spattered bits of ectoplasm and tiny flutters of black fabric.
It was just before dawn that Tucker finally came to the devastating conclusion that his friend was no more. He went home and laid on his bed, spending most of the day locked in his room staring at the ceiling, trying to decide how best to explain to the Fentons what had happened to their son.
Danny stumbled out of the portal, blinking and confused and mercifully whole, just before supper - solving Tucker’s dilemma. Both boys chalked it up to luck and decided to not think about it any more than absolutely necessary.
