Hello, I’m writing a fanfiction about a "Pueblood/half-Blood?" OC who is the grandson of Minerva McGonagall and the same age as Harry who is also a Metamorphmagus.

The entire fanfic is fouces on two main ideas:

1. He has common sense, as in he notices solutions to problems that should have been obvious but often were not.

2. He is a Metamorphmagus, and his ability plays a major role in the story’s progression and his abilities

But a bit of backgound: He developed a strong passion for magical beasts From a young age, It started when he wondered if he could transform into a cat like his grandmother, McGonagall explaines that he could not since her cat form came from her being an Animagus,. That answer made him more angery and curious. He wanted to transform like her but began to wonder whether he could transform into other creatures and the cat example was a special case. This curiosity led him into years of studying Magical Beast that turned into passion for studying the nature and biology of magical creatures.

In this story, I want to expand more on the ability of a Metamorphmagus beyond simple appearance changes. I want him to be a close-quarters fighter while still being able to duel like a normal wizard. Because of that, I want him to use his metamorphmagus to alter his biology to increasing his strength, speed, perception, durabilty, by creating additional muscle mass and changing thier density and create tougher layers of skin for defense. However, to be able to do this he needs to understand how human biology works.

Normal Metamorphmagus abilities in my stiry affect the outer layer of the body, since that is what the user can see and consciously reshape. For example, if Tonks changed herself from an average-sized woman into a six-foot-five muscular man, she could copy the appearance, but not the actual strength, because she would only be changing the outside layer of herself and not her insides, My MC is different because he learns to change himself from the inside out.

He studies Muggle biology and science so he can understand how the body works. By learning about muscle structure, density, and mass, he can enhance his strength. He applies the same logic to his nervous system to improve his perception and reaction time. Later on in the story, around Book 3 he starts to train with Professor Lupin, he applues a thoery he been working on where he change his body to grow dragon-like scales, giving himself durability similar to a dragon’s hide (not from the start but eveuntally when he master it) and even grow wings.

Now as a concept, just this, is it intresting? Is there something that Ive missed? I would love ur opinion on it :)

I've been working on an idea for a Naoya SI fanfic, and i adjusted projection sorcery so it fit with the new naoya interpetation, i would like u guys opinion on things.

PLEASE NOTE: that this is for a fanfic so i know that Canon naoya or projection sorcery may not be able to do this thats why its revised

-Projection Sorcery: Projection Sorcery divides one second into a base of twenty-four frames per second, using the user's field of view as the projection angle of view. The user can trace a predetermined set of movements into those twenty-four frames and execute them within that single second. Maintaining constant activation of Projection Sorcery allows speed and momentum to continually build over time.

While Projection Sorcery is active, anything touched by the user must also abide by the 24 FPS rule while moving. Failure to do so results in the subject becoming immobilized and frozen in an animation frame for one second. Although it lasts only a second, anything caught in that frame is completely vulnerable to attack. The only ways to break free are to wait out the timer, for the user to release the target, or by having the frame struck and shattered. Striking the frame causes the user's attack to bypass any form of reinforcement and directly damage the target's body natural defences.

This effect does not apply only to living beings, but also to non-living matter such as air, stone, debris, and surrounding objects, granting the user a high degree of freedom and environmental control during combat.

Thus, the user may choose whether to prioritize unpredictability and sudden displacement, or fluid speed and overwhelming force.

However, the technique has several limitations as well:

• The predetermined course cannot be adjusted once started.

• If the chosen trajectory excessively ignores physics or exceeds what the body can reasonably perform, the user will be frozen as well.

• The user may only select Points A and B that are physically reachable according to their natural movement capabilities.

• Lower frame counts sacrifice acceleration and power for sudden repositioning.

• Extremely high frame counts grant greater momentum, but require finer control and make movement patterns easier to visually track.

-Technique Lapse: Variable Frame Rate:

• Description: By amplifying the base effect of Projection Sorcery, Naoya is able to manipulate the number of frames per second at which the technique operates, varying from as low as 5 frames per second to as high as 240 frames per second or beyond. Rather than being locked to the standard twenty-four-frame structure, the user can alter how many frames are used to divide one second of movement. When the frame count is changed, the technique automatically adjusts the distance between each frame based on the total path selected between Point A and Point B. The distance remains the same overall, but how it is segmented changes according to the chosen frame rate.
This creates two opposite combat applications: 1.Lower frame rates produce larger gaps between frames, causing movement to appear abrupt, skipping, or teleport-like. This grants explosive bursts of speed across short intervals and makes the user's path harder to read.
2.Higher frame rates shorten the distance between frames, creating smoother motion closer to natural running while greatly increasing momentum buildup, acceleration, and striking force through continuous movement stacking.
At extremely high frame count, the user appear to move fluidly while accumulating more speed. At extremely low frame counts, the user sacrifices that momentum buildup for his movement to turn more erratic. The Lapse Technique retains the same weaknesses as the Neutral Technique: the chosen path cannot be altered once activated, impossible trajectories will freeze the user, and anything touched by the user is still forced to obey the active frame rule, but for the choosen frame rate.

-Technique Reversal: Keyframe Desync:

• Description: By reversing the effect of Projection Sorcery, it inverts the original principle of frame-by-frame movement control, shifting its focus from segmentation to the outcome. Rather than dividing a single second into predetermined frames for a certain path, the reversed technique allows Naoya to designate only the initial and final points of motion. The intermediate proces that normally is constrained by strict "frames" that must be obeyed is entirely omitted, effectively turning it into an instantaneous transition technique. This technique, however, must still follow the rules for Projection Sorcery, so it need ti still be within the range of Projection Sorcery.

-Imaginary Technique: Parallel Rendering:

• Description: Naoya can manifest up to 4 clones, with each clone costing 10% of Naoya full Curse Energy reserve but having 65% of Naoya's Curse Energy Amount at each clone creation. The clones are indistinguishable from the real Naoya, so much so that even the Six Eyes can't distinguish between them. The only way to dispel them is to kill them, whereupon they shatter into small fragments that float and dissolve into nothing.

-Extension Technique: Forced Perspective:

• Description: By freezing something within a frame and holding it up to his eye, Naoya can view the trapped object through a forced perspective that makes it appear larger or smaller than it truly is. Once the target is released from the frame, its actual size changes to match the scale at which it was perceived.

-Extension Technique: Frame Scrubbing:

• Description: Projection Sorcery require specifing a number of movements to be decided per second and to follow through with them, that includes creating sounds since it depends on moving muscles to create sounds and hand movement for handsigns. So Naoya is capable of chanting the full chants and perform the handsigns for a technique in under a second making all his techniques come out at the highest output.

-Extension Technique: Rendering Slipstream: By freezing the surrounding air within frames through Projection Sorcery and then shattering those frames, Naoya forcibly releases compressed air outward before immediately refreezing them and repeating the process. Through continuous cycles of compression, release, and refreezing, he generate powerful air currents that are infused with his Cursed Energy that he can manipulate, allowing him to generate cyclones, cutting winds, and directional gusts at will, etc.... Visually, the technique appears as fractured animation frames floating around pale wind before dispersing. However, this technique doesn't stop the wind from naturally dispersing unless he uses Projection Sorcery again to gather the wind again.

• Rendering Slipstream: Rasengan: by targeting the air in his palm, naoya freeze the air in upto 8 frames with 22 degree between them. When they break the air is explled and refrozen over and over again reating a rotating sphere of high speed pressurized wind that explode out upon impact in razor sharp wind blades.

• Rendering Slipstream: Severe: By freezing the air in front of him into ultra-thin layered strips through Projection Sorcery, Naoya compresses multiple frames of air atop one another. With the swipe of his fingers, he shatters the suspended layers at once, releasing overlapping streams of high-speed wind that converge into razor-thin blades that severes anything in its path.

• Rendering Slipstream: Atmospheric Collapse: By continuing to build up the pressure in the [Rendering Slipstream: Rasengan], the sphere of pressure turns into a small tornado of extremely high pressure that tears things in its way.

• Rendering Slipstream: Dragon's Breath: By continuing to build up the pressure for [Rendering Slipstream: Atmospheric Collapse], the airspeed gets so high the friction between the wind turns into heat, which ionizes the air, turning the wind sphere into a plasma sphere that looks like a swirl of pink/blue/purple energies. Naoya then keeps building up the pressure and speed, increasing the plasma sphere's heat and destructiveness before shooting it out.

• Rendering Slipstream: Jet Step: By freezing the air beneath or behind his feet and instantly shattering the frame, Naoya creates explosive directional thrust. This can be used for sudden bursts of acceleration, midair course correction, rapid evasive movement, or even flight.

-Extension Technuque: High Resolution:

• Description: By applying Projection Sorcery on his brain and nervous system, Naoya gains heightened perception, allowing him to see and process information at a higher rate than normal humans. While the human visual system does not operate in discrete frames, it is limited in temporal resolution. Under normal conditions, humans can only distinguish rapid visual changes up to roughly 50-90 Hz, beyond which motion and flicker blur into continuity. However, High Resolution breaks this limitation, allowing Naoya to resolve changes at far higher frequencies, effectively perceiving events that would normally occur "between" moments of human awareness, thus giving them heightened perception. However, just because Naoya can register a movement, doesn't mean he can react to it.

-Extension Technique: Multiplane Pathing:

(Not sure about this)

• Description: By conceptualizing the innovative approach pioneered by Disney in animation, the Multiplane Camera introduces an extraordinary sense of depth by manipulating various layers of artwork at distinct speeds. By perceiving his surroundings as a collection of background layers akin animation, he constructs a simple framework to reinforce this captivating effect. He can choose to move "behind" the foreground layer of reality. To an observer, Naoya would seem to pass through solid objects or people because he is technically moving on a different "cel" or layer of the animation. This can also work with the neutral application of projection sorscry, allowing him to somewhat break through the laws of physics and fade through obstacles or the ground to attack at different angles. This provides a form of pseudo-intangibility similar to Obito's Kamui but based on perspective rather than dimensions, and can still be broken or prevented if the environment is destroyed or altered, that he's moving through, forcing him out of the background layer and techniques that affect space in a way that prevents Naoya from passing through it, like the limitless or infinity.

-Maximum Technique: Final Cut:

• Description: By pushing his Cursed Technique to its absolute limit, Naoya temporarily change the battlefield itself into a complete animation sequence rather than a space governed by normal reality. Instead of applying Projection Sorcery only to himself or selected targets, Naoya imposes it across the entire of his vision at once. Every object, person, particle of air, and point in space is forcibly converted into part of a single projected scene.

For one second, the environment is divided into an number of frames from the standard twenty-four to beyond, creating a domain-like field of layered motion paths. During this second, Naoya alone retains full awareness and control over the sequence. Everything else is trapped within predetermined frame progression. All targets inside the affected range move according to predicted frame paths that they dont know and would've done. Any failure to obey due to Naoya interfernce instantly freezes them in place, often multiple times in succession, causing chained immobilization. Every frame transition within the field generates stored kinetic force. Naoya absorbs the accumulated momentum of the entire projected domain and concentrates it into a final strike at the end of the technique. This allows him to unleash a blow carrying the combined acceleration of countless layered movements. Within the projected second, Naoya may reorder relative perspective and path priority:

1. Make distant attacks arrive first.

2. Redirect frozen air into slicing cyclones through Rendering Slipstream.

3. TBD

At the end of the one-second sequence, all delayed motion resolves simultaneously. Frozen debris launches, air pressure detonates outward, clones vanish into converging strikes, and Naoya delivers a single high-speed finishing attack empowered by the harvested momentum. To observers, it appears as though reality skips forward and everything happens at once.
