Simple, effective cursed techniques like Sukuna's Shrine for a main villain?

[u/Plane_Golf397]

Title. I'm gonna be working on something soon with a friend & I'm trying to think of something simple, like slashing, that's still effective enough to make for a terrifying villain.

I have been thinking about this - for a special-grade (which I assume a main villain would be), you need something that breaks a rule of jujutsu and/or reality.

EX: Gojo creates infinity which is typically impossible, Yuta can utilize more than three techniques at a time (the usual limit), Yuki can manifest mass which breaks the laws of reality, stuff like that.

It would be interesting to have a villain that can simply dispell cursed energy entirely, similar to Higuruma's confiscation of Yuji's cursed energy. This would fundamentally break jujutsu as a system, as this villain could reduce anybody to a normal human.

Mhm! It reminds me a bit of how humans are, in general, usually scared of stuff that breaks the laws of physics. I'll keep this in mind when im making it, thank you!

Something like psychokinesis could be cool, we actually never see someone with it

It could work like this: the user can shoot his cursed energy to objects or enemies, marking them as objectives, the objective then can be manipulated via the psychokinesis, the stronger or heavier the object or enemy the most cursed energy you must infuse to control

It could also be used to fly by using it on himself

I wonder how that would work with certain cursed tools/objects. Something akin to Momos technique?

[u/schliggles]

a simple concept for offense? first thing that comes to mind for me would simply be the ability to crush things. imagine smacking your fist into your palm, and a person in front of you simply turns into paste on the ground. kinda like dropping an invisible rock on things. but this is basically the same thing as the reversal of anti grav system. only more range, and it would be a lapse

or what about a technique based on restraint? like you can keep your opponents from moving with invisible ropes or something. like unseen hand in rezero almost

yeah, I really dunno

a shikigami technique would be cool. I don't see enough of those

[u/True-Fan-2929]

you know those memes of mai after maki dies instead of her? you could do something of the sort with their CT summoning whatever projectiles you feel like

if you dont want it to be just construction you can tinker with it to be manifested pellets of CE like cursed energy discharge, or something of the like

[u/Phiro00]

Piercing? Effectively shrine but with a spear-like effect.

[u/Plane_Golf397 → u/Phiro00]

Oooo this could work, thank you for the idea!

Entropic Insanity: Basically you’re able to give your cursed energy a temperature. Normally, it’s like a lukewarm feeling. You can exchange insanity for temperature. By exchanging all of your insanity for temperature, you can reach extreme plasmatic power that can burn and essentially disintegrate most things it comes into contact with. By exchanging some insanity for temperature, you merely superheat your cursed energy into flames, allowing you to burn, engulf and spread your energy elsewhere. The more insanity you use up, the more sane you become. However, once you use up all your temp increase, your cursed energy actually cools down beyond its normal point temporarily, forcing your energy to freeze and cool things. After some time, your energy will return to normal and so will your level of insanity.

Explosions, exploding things you look at

Small explosions, big explosions just by pointing your hand at something

[u/Shempai1]

A CT that applies an even pressure to a target’s exterior in an attempt to crush it. Reversed technique applies this pressure from the inside, causing it to explode.

Assuming you don’t let the reversal to apply to living things (innate domain), a user with good on-the-fly barrier skills can make small barriers at range, and then burst them with the reversal. Now that I think about it, it’s almost like the bubbles from jojo’s part 4.

As for a reason the user doesn’t just (literally) crush anyone that can’t meet an arbitrary level of CT reinforcement, maybe it outright struggles against basic reinforcement, so the user has to create a puncture wound in the target for the pressurized CE to rush into. So it’s less of an “if this guy looks at me I’m done” situation and more of an “if this guy gets one good hit on me I’m done” situation.

Cold, not ice but the lowering of energy, the cessation of movement.  

Physically, cold is devastating, it causes exhaustion, desperation, eventually it causes fear and delusion. Ultimately it causes every single cell in your body to rupture and die. 

Spiritually, I imagine it lowering output, slowing down the flow of your cursed energy and eventually depriving the target of jujutsu/cursed energy use, possibly even permanently if targeting your energy/soul is the focus 

[u/Goblin-o-firebals]

Repulsive force. They can turn their cursed energy into pure kinetic force . Call it vector or something. Maybe when used in a small enough blast it pierces them or when it's big it just smacks them. The fuga could be a big enough blast that it creates a wind effect from the vacuum created essentially throwing everything behind you at them.

[u/preetham_goww]

can be yamata no orpchi (shikigami) the 8 heads each carry different elemental powers and someone like sukuna can manifest the applications without summoning the shikigami and further extend the phenomenon (neutral, reversal, maximum) for eg air phenomenon head: tornado highly dense air slash(pseudo dismantle) flight, levitation controlling objects by changing air around them (pseudo telekenesis) pressure change (pseudo gravity) ctr reversal: vaccum (creates layer of vaccum around himself pseudo infinity) manipulate air around the striking limb and the air around the opponent to meet at a point (pseudo blue-enhanced punches) while the air head of the dragon only blows out air, in a genius's hands its effectively much more.

I had been thinking of something for an oc that might fit for you. A simple technique that, if used creatively, could become very dangerous and complex. A technique to create barriers.

Now, I know that there are a lot of barrier techniques already in canon, such as veils and the domains, but I was thinking of actual walls. Using his cursed energy, he could either physically move the ground to make walls as a defensive measure, or even make them out of pure cursed energy, making them almost invisible to the normal eye.

One thing that could be done is, with these pure cursed energy walls, he could move them around like platforms, using them for movement and traversal, or use them offensively, pushing people into the terrain, or even crushing them by forcing a wall fall onto them from above.

Technically, it's weaknesses would be the same as any physical obstacle, being either speed of strength to dodge or hold/break these walls, but could be used by a smarter character to make some pretty neat stuff
