someone asked for nizzie headcanons ?
(I’ll be following the gknd canon that Lizzie is an alien btw, I think it matters)
• For their first meeting, I’ve seen lots of cute protrayals of how that could’ve happened, but in my vision Numbuh 74.239 wanted to make Lizzie meet Nigel in an easy and succint manner by having her be caught in some teenager evil scheme in the school cafeteria and have Lizzie be saved by Nigel, that was scouting the area for threats nearby. Lizzie more or less got the plan but kind of forgot she was supposed to be playing damsel in distress half the way, so in the process she cursed all of the teenagers generations, started a food fight at the cafeteria, bit the hand of some teen that tried to grab her and kicked them in the nuts. Eventually Nigel swept into the scene and fled with her while fighting the hoard of the angry teens, the both of them introducing themselves to one another amidst the chaos.
Eventually they were sent to the principal’s office, and when the adult was more than ready to give them both detention for causing the commotion, especially with Nigel’s bad record, but Lizzie managed to sweet talk her way and manipulate the adult to let them get away with it scot-free this time. At this point Nigel was already smitten, and does this whole thing where he wants to treat her to some ice cream for saving his butt. And the rest is history :)
• When Lizzie is in a particular bad mood or when Nigel needs to make ammends with her or something, he asks Numbuh 5 if he can accompany her in one of her candy-hunting missions so he can grab an exotic candy for his girlfriend. It works like a charm.
• It’s uncountable how many times Lizzie muted Nigel’s KND communicator just so he could spend time with her uninterrupted, especially when she was forcing him to take a break after too many missions in a row. The first few times Numbuh 1 caught her in the act, nowadays she’s more sneaky about it and manages to get him to rest well before he catches on.
• Lizzie is very good at her disguise, but sometimes she can’t help herself but show some of her abilities that could be compared to elite KND operatives, and Nigel is very observant. Even his paranoid but creative mind wouldn’t ever figure out the truth on it’s own, he’s theorized that Lizzie was maybe a KND operative that was forcefully deactivated and decomissioned ahead of time due to breaking one of the rules. He hyperfixated on that hypothesis for weeks (giving Lizzie a major headache) until Numbuh 362 told his to just fucking trust the Code Module database that explicitly said she had never been an operative ever, and he eventually chilled out.
• Despite trying to recruit Lizzie to the KND cause due to her potential several times, and failing miserably each time, Numbuh 1 is secretly happy that she never accepted it. Knowing that even when he reaches 13 most of his happy memories with her will be intact makes the prospect of his inevitable decomission a little easier to deal with.
• While Nigel recognizes he doesn’t have a lot of hobbies outside comic books, he knows his girlfriend has a bunch of them, and while spending time with her, he learned to appreciate what he once thought were boring things, and became enamored with how Lizzie engages with them.
He’d keep each of Lizzie’s romantic poems safe in a little box despite finding them too chessy, learn a thing or two about gardening and planting flowers with her green thumb and although he won’t voluntarily eat her food because of her atricious cooking, sometimes he takes her out especifically to try different foods and try to appease her weird taste. (And the way her eyes shine when she’s talking about a culture from another country she’s been researching about? It makes his heart beat all funny).
Numbuh 1 even got a taste for photography with her! It’s something he keeps more private by implating a small camera feature on his goggles with 2x4 tech and unlike Lizzie, he prefers to take photos of pretty scenery rather than photographh people, animals or foods. Getting to show her his photos once he got a big enough collection was awesome.
• It’s admittedly very hard to get Nigel to go on dates with Lizzie, as there are tons of reasons why they don’t usually don’t go according to plan. First there’s the KND duty, a lot of dates were abruptly ended by an emergency call from the Moonbase. Then there’s the fact that Nigel’s paranoia can start to flare up and he’ll be antsy in places with tons of adults around like carnivals, beaches or fancy restaurants (that while manageable, isn’t ideal). Not to mention that Nigel seems alergic to doing all the romantic things and showing his love to her in public, and while Lizzie COULD cave and go to a Monster Jam with him, she’d hardly consider that a proper place for a romantic date.
In the end, the dates they found worked best for them were trips to the ice-cream shop, movie nights on Nigel’s house, going to the playground and playing on the swings and stargazing past their bedtime. Nigel still hates going on dates for finding romantic stuff boring and expensive, and Lizzie will still guilt him into going anyway after he blows her off one too many times. It’s how their dynamic goes!
• It’s sweet to consider just how safe Lizzie makes Nigel. She’s a grounding presence for him, someone brave and loud who isn’t willing to back down. Someone who can easily be twice as stubborn as him, so loud and angry at times but without a doubt so very patient with him and kind with all her grand love gestures. She always makes sure to get her priorities straight, enough that it makes Nigel also pay attention to the smaller things he never gave any mind to. She strives to live each day like it’s her last day on Earth just like him, and wants to make an impact in her own way, and he can’t help himself but admire her so much for it.
She makes it feel okay for him to be vulnerable, and being the selfless leader that’s always looking out for others above himself to make sure everything goes smoothly, it’s nice to have someone who only has eyes for him and has his best interest at mind. After grueling missions where the might Numbuh One stood victorious in the battle against adult tiranny, Lizzie was the one to look through his glasses and see in his eyes that her Nigey just needed an 18 hour nap and a good break to catch on his favorite ninja cartoons and just RELAX for a while. She reminds him that fighting adults isn’t the only goal, but protecting childrens childhoods all around the globe. And that includes him, protecting him, his childhood.
He trusted her with everything he had, and that’s because he loves her so so much.
• But Lizzie is a liar, Nigel was always Lizzie’s mission target. However, even if at first she was spending time with him only for the mission, she eventually madly fell in love in a deeper level than when she fell in love with Earth and it’s culture. Tho she only admitted that to herself after Operation P.O.O.L, getting to experience a dangerous KND mission by her lovers side while he supported her the whole way made her giddy to imagine everything they could get up to while in a GKND mission together. It made her work even harder to convince the higher ups to recruit Nigel as Earth’s Intergalactical Operative.
She truly thought it would be for the best. For Nigel, for herself, for the Galactic Kids Next Door.
• Having Nigel in her life, it makes Lizzie feel like it’s okay to be herself. Despite him being someone that doesn’t know important details about her life, he’s simultaneously the first person who’s ever looked at her and truly seen her for what she is. His courage, self confidence, charisma and assuredness of what he wants in life makes her eager to explore things about herself that she never thought she had the capacity to, he makes all the talks about soulmates and destiny seem true because being with him feels like the best moment she’s had in a long time after joining the KND. He’s so kind and patient to her flaws, encourages her to let out her anger and work through her insecurities instead of judging her and demanding her to suck it up and stop whining, and he’s so dedicated to her cause, the KND, and yet wants her despite when she pretends to hate his literal life goal.
Nigel inspired Lizzie to get back to doing the things she loved to do and had to give up for a “grander” intergalactical purpose, he inspired her to love with everything she’s got and never look back. She knows she needs him and wants him because suddenly he’s even more important to her than any organization or lousy mission could ever be, because she loves him so so much.
• Between all the times they bicker and fight, one sure fire they use to settle things in with paintball matches. My god, these two are absolute MANIACS when it comes to competitive games like that. They massacre teams left and right while threatening and dancing around each other until their final confrontation. But once their game ends and one of them gets put victorious, they have already used up all their pent up anger and have basically forgotten all about their fight in favor to gush about each other’s performance in game.
And if someone asked what started the conflict in the first place, it be something real stupid that got blown out of proportion like Lizzie making Nigel pay for an waaay too expensive dinner which REALLY pissed him off or because Nigel looked at a random girl for far too much time in Lizzie’s humble opinion.
• Giving Lizzie the access code to the Treehouse was one of the worst mistakes Nigel could’ve done, as her clingy ass takes every single opportunity to see her boyfriend and see if he’s free for a date. Nigel would come to his room to find (lovely, but too cheesy for his linking) poems and love letters that his friends would tease him endlessly about whenever they stumbled upon it. It got even worse one time when Lizzie discovered Numbuh 2’s taste for romance novels and blackmailed him into giving her occasional live updates on when Nigel would arrive back to the Treehouse from a mission so she’d have the best timing to barge in. Numbuh 5 caught on to her dastardly plan real quick but at least she got 6 succesful dates out of it in the end.
Numbuh 1 doesn’t like being teased by his friends or all that public display of affection and vulnerability and whines about most of her loud gestures, but deep down he knows he wouldn’t have his crazy girlfriend any other way.
• 5 out of 4 gifts Nigel gifts to Lizzie have some sort of spy apparatus that she has to get out. At first she tried pretending she was mad and Nigel would promise he’d never do it again only to DO IT AGAIN ANYWAY. But seriously, how could he not want a sure fire way to check on his girlfriend when he’s like a bajillion percent sure her parents are robots that are waiting for the right time to turn her into a delightfulized little robot! Or how her grandmother may be poisoning Lizzie so she won’t like going out to play on reccess!!! So he does it to be a perfectly normal boyfriend looking out for his girlfriend, and he always makes sure to bring audio bugs and spy cameras to fill her house with everytime he visits. Someday she’s BOUND to miss one and that will keep his mind at peace.
In the end, Lizzie just pretends to not see the small camera he installed in the mirror of her vanity desk, as it doesn’t have a good angle and only catches a very small corner of her room in it’s view. And it somewhat worked! He tried to bug her house less and less ever since then.
• Lizzie would always get pissed when Nigel refused her offer to help him study to upcoming tests, as he firmly believes getting kids to study outside of school is a prime example of adults trying to brainwash them.
Despite being pissed, Lizzie would totally let Nigel cheat from her answersheet lol
And I think that’s it! All the nizzie headcanons I could think of right now. I probably got more, but these are the ones that come to mind. Thank you if you read everything and if you have any you’d like to add to my colection, my inbox is always open -w-
