#cu chulainn prototype

Proto Cu

-Whether it be through a clash of ideals; being on opposing sides- or possibly from even invoking his pent-up anger- as Proto has a pretty short temper, it's not that hard to rile him up.

-However, although he is easily angered- to become his enemy may be more difficult than expected. He is more likely to view one as an enemy if the two of you bitterly clash over ideals he feels sensitive about; if you get in the way of those he wishes to protect; or are simply placed as opponents on different parts of the battlefield. Overall, it could either be a personally motivated dislike towards you, something that threatens his identity as 'Cu Chulainn'- or just him adhering to his duty.

-Those who aim to manipulate him or act as if they're superior will get dragged to equal ground. He will show them exactly why they shouldn't mess with him.

-Depending on context- Proto won't hold back in his disregard and frustrations towards you as an enemy. That means showcasing openly hostile behavior, glaring- the whole lot! Ever the one to struggle with composing himself and suppressing his emotions; although he's mature enough to work alongside you if need be- he'll openly showcase his contempt, dislike seeping from every pore.

-Get prepared for endless bouts of competition, heated debates and a lot of grumbling/ harsh banter shared between you both! Proto Cu is both an extremely fiery AND icy enemy to have, so you'll be butting heads a LOT. Though he does give off the impression of being a rather cool and relaxed character, deep down he has a lot of emotions churning inside- that may be aching to spill out.

-For example, if this is a combative enemies-to-lovers relationship, the two of you may be crossing weapons and awful lot, as well as having him challenge you to duels (he's very defensive over his pride). And even if it's a less combat orientated situation, he's still going to give you a rather hard time, doing his utmost to intimidate you into leaving him alone. He may give you a wide berth at first, as well.

-On the other hand, if the two of you are simply enemies due to being on opposite sides, it is more likely that he'll be less hostile; but certainly a lot colder in temperament at first- or at least until he gets to know you a little better. It may be his way of making his stance clear towards you: he is not one to be underestimated. Look down on Proto, and he'll rip you apart.

-That doesn't mean he'll be opposed to a bit of joking and humor, but if it's decreed that he must kill you, then Proto Cu will doggedly adhere to accomplishing such goals (that's why it's pretty scary to be his enemy sometimes, especially when he's willing to accomplish his tasks at any cost).

-In the case that you're both enemies that are made to work together, or grow to learn more about one another off the battlefield; though Proto will maintain a harsh and grumpy exterior at first (he'll likely complain a lot at first despite begrudgingly helping out anyway), he's a very open-minded lad. This means that the slightest thing that the two of you grow to enjoy talking about or doing together will be enough of a catalyst for him to gradually warm up towards you.

-If you're technically no longer an 'enemy', then there's a high chance that he'll come around eventually. He's not opposed to forgiveness.

-Over time, what starts off as a hostile relationship gradually ebbs into a rivalry, and erupts into friendly banter and many shared moments together, both of you growing closer by the day. By this time, Proto will likely start cracking jokes and maybe even lapsing into annoying pranks, as well as getting a bit more touchy-feely with you; cheerfully aiming to get a little on your nerves- at the same time as gradually letting you into his world.

-It's a natural development, and depending on what sides of you he gets to see; Proto Cu may quickly latch on, becoming rather attached now that he knows that he can genuinely rely on you. Though there's still a lot of back-and-forth banter, and some harsh jabs; he's now genuinely happy to be around you!

-Things may start to take a turn for the strange once his affections start to develop. Despite still operating as rivals, he becomes louder, bawdier and even more of a show-off than ever before; almost as if he's yearning for your attention. Red eyes sparkling whenever you respond in kind, the relationship begins to take an interesting new turn... (also just when did your volleys of banter become so tempting, so alluring?! Proto can't quite handle the heat anymore.)

-As for romance, seeing as you were former enemies; he may be a bit prideful in regards to letting his feelings known, preferring if you were to yield your heart to him first (it'd fill his heart with joy). But as it's Proto, he's not going to be able to hide them that well, as he's not quite as talented at concealing his deeper emotions as the other Cu are.

-It's likely that the romantic development may occur at the most unlikely of times and in a very surreal way, but when it does; it's a moment full of unrestrained passion.

-As lovers, it's bound to be a fun time; as the two of you can keep one another on your toes. There's still a lot of competition and some clashes of pride, but now love and affection rings true within every gesture and touch (also he's much more easily flustered).

-Over time, the atmosphere evens into one of a deep mutual affection. He's so glad that such a strong bond of trust has formed between you both, and hopes that things can stay this way... he'd be heartbroken if you were to return to being foes again.

Lancer Cu

-Lancer's famous quote is 'yesterday's enemy is today's drinking buddy!' This likely means that his views on whether a person is his enemy or not are rather unpredictable, and can change by the day. Just like Proto, it's not that hard to get under his skin, but as he's rather laid back (but also relentless) it would likely be a struggle to become his enemy long-term.

-Similar to Proto, it's more likely that he'll either personally dislike someone (they may insult his pride, or they may clash over ideals that are dear to him, or he may even just dislike their vibes); or simply see them as an enemy because they are in the way of him accomplishing his goals, or are threatening those who he cares for. In that way, I believe that him and Proto are more or less the same in this sense.

-Lancer also seems to dislike those who talk circles around him, as well as those who play him for a fool. Things will go sour at an incredibly fast rate if anybody tries to pull one over Lancer: he'll not only avoid them, but if they really insult his pride, Lancer will overpower them enough to force them to respect him. He'll claw any sense of superiority away; but will still work alongside them if he has to.

-Lancer definitely seems to enjoy bantering and playing around with his enemies before finishing them off- however once they unleash his temper, there's no holding back. He will absolutely eviscerate them, rendering them to dust. His approach to enemies can range from being rather playful and laid-back, to being downright terrifying and murderous at times.

-Depending on as to what made you enemies in the first place, he may range from regarding you rather neutrally, to even extremely coldly. However, if you managed to win his respect upon the battlefield, or in terms of your competing wits etc. then he will definitely acknowledge you as a worthy opponent. But similarly to Proto, he will bite back, and regard you rather harshly at times, showcasing just how intimidating he can be.

-However, if the situation changes, and the two of you are made to work as a team; then he'll help out at any cost. And if it's an entertaining time or he finds a bit of common ground, then he likely won't take that long to warm up to you. All Cu are rather accepting individuals, and that acceptance does extend to even his enemies.

-But that doesn't mean he'll hold back though. Lancer will likely bruise you with some sharp comments and extremely caustic wit- shooting right to the heart of how exactly he feels and regards you as a person. Lancer is not one to pull his punches against a rival!!

-Even when playfully ribbing and bantering with you as a former enemy, he will still showcase in his demeanor that he's not one to mess with; emphasizing just how powerful he is. Even if you're allies now, he will cut you down if you betray him.

-Although if said rival was to invite him for a drink or a good meal... then who would he be to decline?! Despite any ill will he may hold against them, Cu will let all bygones be bygones; celebrating passionately by the side of even his most disliked foes if the occasion calls for it.

-Even better if you're up for some training or a good spar, nothing quite beats venting out his frustrations in a battle. It won't be long before he develops a sense of respect towards them. As for trust, well... that may be a much greater challenge to develop.

-He will ABSOLUTELY get a kick out of making jabs and jeering at his 'enemy-turned-ally', making fun out of them and exchanging light quips in the hopes of annoying them. Even better if you entertain him when he does, Lancer wholly enjoying the reactions he can inspire from you.

-As the two of you begin to hang out in earnest, running into one another and even enjoying fun activities by one another's side; Lancer's perspective begins to shift (rather quickly). Though you get under his skin at times, and you clash a lot- he genuinely enjoys it.

-He gets a kick out of being able to both volley a bit of hostility and friendly support with you at the same time; and before the two of you even realise it, you've become staple part of one another's lives.

-Could this be a rivalry, or something more?? Who knows, Lancer likes to just enjoy things as is. If it's due time for flirting, then so be it. To him there may be nothing wrong with engaging in a bit of passionate romance with a former enemy, especially if it feels good; and the feeling is mutual!

-The progression from enemies to lovers is bound to flow rather naturally. If it happens, he won't be opposed to it at all. Besides now this levels the playing field even more- now he can challenge you in the field of love as well!!

-Even if his lover was formerly his enemy, Lancer will still treasure them dearly, wishing to have an overall good time, overjoyed to finally hold them close. Hopefully the two of you will never become enemies again- he's not sure how well his heart would handle it, no matter how nonchalantly he acts on the surface.

-But for now, he'll cherish every moment as lovers to the utmost (and thanks to your rivalry, it means there's even more room for adventure and fun, which he's grateful for).

Caster Cu

-In terms of motivations for becoming enemies, I feel as if Caster Cu would be overall very similar to Proto and Lancer. Personal motivations, duty, clashes over ideals, disliking one another's vibes, simply being on opposite ends of the battlefield; or being a threat to his loved ones- would all be possible means behind becoming his enemy.

-But I also feel as if he has a very strong energy of 'NOTHING PERSONAL, KID'. As in, if the two of you are enemies, then he may be rather nonplussed about it, especially if he deems the situation as 'not that deep'. Whether it ends in him fighting you to the death or avoiding you, then he'll do whatever he deems is best for the situation.

-Even the way he regards his foes may vary wildly, from those who he views as just happening to face the bad luck of being his enemy, to some that he will direct his utmost wrath towards. I can imagine him showcasing some frustration or reacting negatively to someone who annoys him, but I feel like Caster is generally even less hostile than Proto and Lancer. However, that doesn't mean he won't hesitate to destroy them if it aligns with his duty, or if he deems it correct to do so.

-They would really have to anger him or hurt those who he cares deeply for in order for Caster to become completely murderous and full of rage towards them; and once he reaches that stage, he'll be a horrifying foe to compete against, willing to dive to any lengths to destroy his enemies.

-So with that in mind, Caster is likely to be a pretty chill enemy to have. He won't hesitate to knock a foe with his staff and runes if need be, but if you're working as a team; then he'll go with it- whilst grumbling all the way. He is the wise one, and therefore as a result, he will try to be the bigger person (but if you're picking a fight, then hell, he'll absolutely oblige!!!)

-However, it must be noted that this is the same Caster who once hosted an illegal gambling ring in the Kara no Kyoukai event. He's definitely got just as much of a dangerous side as Proto and Lancer, but what makes Caster an even more terrifying enemy is that he's extremely good at concealing his deeper emotions at times. This means that if need be, he could totally manipulate the hell out of an enemy, trapping them within his web (but as to whether he would or not is context dependent).

-In conclusion, Caster as an enemy is a mystery to me as well, as his approach can vary wildly; and he also can change his attitude towards an enemy pretty quickly as well. As soon as you're his ally, he too will work alongside you- despite any reservations he may hide inside.

-Caster can be very direct with his feelings as well though, so he may be similar to Proto and Lancer in which he may avoid you at first, openly grumble and complain to you about how he dislikes you; laugh at you and tease you in a pretty annoying manner, as well as enjoying being a bit of a pain towards you. He'll still help you as an ally- though that doesn't mean you'll be safe from Caster's jabs, as this guy knows how to smack people in the face with some painfully direct honesty!!

-As time progresses, the teasing rapidly picks up in pace, Caster indulging heavily in having a bit of fun! It's nice, for the two of you to have such a chill time as enemies. Always up for a good time, he invites you out sometimes. There's never a dull moment between you both, even occasionally giving one another a pat on the back for support.

-In addition to that, mutual support goes a long way for Caster. Just knowing that you're there to help out in a pinch-despite serving as former enemies- is more than enough motivation for him to give his all to helping you as well. With every assist comes a fist bump, with every save comes a hearty meal and some good company. It's becoming rather comforting for him to be around you, happy to just kick back; test some new moves- and have an overall exciting time by your side.

-Bygones are definitely bygones by this point. He doesn't mind the past of your relationship at all. What matters more is how the two of you relate to one another right now!!

-Now as for romance, Caster's got a few too many secrets locked within that heart of his, so I'd assume that any romantic developments will be more likely to be of the casual kind at first. Banter evolves into flirting as he teasingly asks if you'd wanna get a bit more... intimate for the night(?!); displaying a clear attraction towards you, yet also giving no clue as to how deeply his feelings may lie.

-Depending on how you answer, things may be 'played by ear' at first. Abandoned cigarettes, wandering hands beneath a waning moon, drifting forest beds that disappear beneath a misty breeze...it'll likely start off as a very spontaneous and exhilarating time.

-As lovers, Caster may remain a mystery at first; but that doesn't mean he won't unravel along the way....

-Honestly, Caster Cu romance headcanons stump me every time. I do think he'd be similar to Lancer and Proto overall, just with more secrets and mystery this time around.

Cu Alter

-In terms of the other Cu Chulainn, they tend to wrangle between balancing their sense of duty with their many emotions; sometimes even struggling to express what's going on within. However, as Cu Alter claims to be lacking in emotion, he serves as a complete juxtaposition to the others, in the way in which he's managed to somehow place duty and instinct above all else.

-In this case, it is probable that Cu Alter would simply destroy an enemy if need be. That's his duty as a tool, after all. To remove all threats, gouging into them with his spear. At first, he views you no differently; entirely committed to his job. Personal thoughts be damned, only actions reign supreme with him.

-However, in the case that the enemy is a good fighter or keeps him on his toes- giving him full permission to unshackle his restraints- then Cu Alter may subconsciously enjoy things a little. Not that he'd admit it aloud, though.

-If he has an enemy that he isn't allowed to kill (i.e. a teammate) or is around an enemy he dislikes for reasons that don't place them as being in the way of his job, then Alter will likely just avoid them as much as he possibly can, and use intimidation as a means to scare them away if they push his boundaries. And if he can't scare them off, well... he'll begrudgingly suffer through their presence if need be.

-Cu Alter will absolutely threaten this enemy at first, pointing his spear directly at them; trying to overpower them with his terrifying aura and presence. If you're not aware of who he's meant to playing the role of by now, then he'll make it abundantly clear how you should see him, especially seeing as he has yet to view you as an ally himself.

-Fear him, despise him. He's your enemy, after all. He doesn't want your mercy, but a rematch? He'll be down for that!!

-He is pretty hostile in general, threatening those who dare to tread close; and openly barking orders and insults, so an enemy of his will be subjected to very similar treatment- only likely to an even worse extent, as he will dislike their company at first.

-It will take quite a while for the relationship to improve. Cu Alter is not as likely as the other Cu to openly showcase his growing affections towards a former enemy.

-However, if Cu Alter grumbles some advice that sounds like sharp insults, that is a very good sign that he may actually like you enough to care about your health. And if his tail starts wagging whenever you're nearby... that's a brilliant sign that he may be secretly coming around to not just tolerating- but genuinely appreciating- your presence!

-The change from being enemies to allies will likely be so subtle that it can be easily missed. Cu Alter doesn't seem quite as friendly nor as open as the others, and won't forgive so quickly; but on the other hand, seeing as he views himself as a beast of instinct- how he regards someone as an enemy may be slightly different to expected.

-This may manifest in him also joining you for events sometimes, or in letting down his mighty walls ever-so-slightly. You may start to see him more often, as he may make less of a concentrated effort to avoid you, and will likely start sharing a few opinions on things (rarely). At some point, he may let his previous grudges go (or maybe not).

-And if you're a lover of combat, then holy moly; he'll be absolutely bouncing off the walls for some simulator training or sparring together (not that he'll openly state that though). In terms of FGO, I feel like Cu Alter may also be more willing to join the former enemy on missions once he grows to care for them, although he's the type to join even his worst enemy on the battlefield if need be.

-As for romantic development, it may be very subtle. It could possibly show in him not minding you being by his side, spiky tail wagging with earnest. Protecting you whenever you're in danger. Listening to you- even when he complains and grumbles at you. If he even goes as far as to openly declare his intent to serve you with his all... then his feelings will likely run very deeply.
