#springlike limbs

Bubble/Sleep Gas: The user makes bubbles of wonderful smelling sleeping gas, making it safer to move around and aim in the contained bubble. Effectively making bubbles that act like sleeping gas grenades that can float around.

This Transformation type Quirk allows the user to change their legs from the knee down into small air pumps. The user can condense these pumps to fill them full of air and release it as condensed air. This grants the user a high burst of movement, sending them flying through the air. This is a quick and powerful burst, letting the user bounce and redirect themselves with ease. The more the user pumps air into their legs, the more powerful the burst they unleashed, able to move the user like a blur at the maximum power output of it. This gives the user a good mobility tool, launching themselves through the air at high speeds to get around faster. If nothing else, the user would be able to body-slam their way into people as an offensive option. Though using the Quirk too much can cause these pumps to get stuck, leaving the user open. The user needs to keep some control over their breathing in order to keep the pumps going.

This Emitter type Quirk activates whenever the user touches something, causing a coiling-like effect on the target. This imparts the properties of a spring onto the target, with the user able to apply this effect up to medium ranges from the point of contact. The user can cause the Quirk target to target itself or the area around it, such as suddenly making a floor tile into a spring tile trap or causing a door to coil up to launch it at someone. The user can apply this to people as well, like coiling their own legs back to jump forward or launching someone with their coiled body. Once the springs are uncoiled, the target returns to normal. This gives the user a good mix of options, able to turn their surroundings into a death trap of springs. They can launch random objects with springs, booby trap the area with spring tiles, coil up the terrain to help get around faster, fire off enemies into the horizon, launch allies to move them around, augment themselves with springy additions, or simply throw themselves through the air.  Though the Quirk requires contact with something to make work. Applying this to targets can end up having unpredictable and dangerous results with how things launch, such as accidentally breaking or hurting someone, including the user.

This Transformation type Quirk allows the user to sprout out an additional set of arms from their upper back. These limbs are coiled up like springs. The user can launch these arms outward over several meters. These new arms are notably stronger, able to knock people down with a single punch and pull the user around. The user still has some control over the arms after they are extended. This gives the user a decent mix of offense and mobility, able to strike out with their coiled arms. They can grapple foes from afar, pull themselves around the battlefield, beat down enemies with heavy hits, grab objects from afar, or just enjoy having extra hands to help them out. Though this only works on the extra arms, leaving the rest of the user open. The coils can take a bit to charge their spring and can get tired if the user applies them too much. The extended arms can still be grabbed.

This Transformation type Quirk allows the user to pull back their limbs, forming various coils as they do. Doing so will start to build up an electrical charge within their limbs, building up more with each coil. The user can unleash this electricity by firing it out of their limbs or using their arms in tandem with each other. The user has a lot of control over the electricity and how it is utilized, such as making a ball of electricity fire out or making a wave of it. This gives the user a solid combat Quirk, unleashing massive charges upon their foes. They can fire out various electrical attacks, destroy with bolts of lightning, use their arms to fire out metal, unleash their electricity as a massive blast, or simply use it to pull their body parts away from attacks. Though this is limited to the limbs and does require them to build up the charge. Releasing all the electricity can cause their arms to fizzle out, requiring some time to regain feeling in their arms.

This Transformation type Quirk allows the user to coil up their limbs like a spring. As they do, they begin to form a spiral of energy around the coils. The user can fire this energy outward, spinning out of their limbs and launching back whatever it touches. This energy is both quick and powerful, with even a single ring being able to knock back an opponent. The more the user builds up the coil, the more powerful blasts they can produce, with the full charge being able to demolish a truck. This gives the user a great offensive tool, plowing through their opponents with a powerful push. If nothing else, it can work as a decent movement option, launching themselves with the force of their blasts. Though this does require the user to charge up the energy, leaving them open to attack or being caught off guard. Using the Quirk too much can be exhausting on the limbs, causing them to become sore, making prolonged fights a problem.

"Air Cannon" is pretty neat. It's one of the more interesting Quirks that All For One has, both for its original uses and its combinations. Like how the user can fire out a condensed shot of air or make sweeping crescent attacks. Or when Tomura combined with "Radiowaves to make an EMP, or when All For One made these giant wave attacks. It's probably one of the few All For One Quirks that I wish belonged to someone else, if only to see the full scope of it. Because I really think that there could have been more interesting ways to use it.

This Transformation type Quirk activates whenever the user's body is hit by an attack. When they are, their body will start to coil up like a spring. The user may then launch the attack back at the target, nullifying any damage that would have been done to them. With this, the user can hold and redirect an attack with their body, like hitting one of their other opponents with the attack. The more powerful the attack, the more the user's body coils up, though they can help disperse this pressure between body parts, like using both arms against a massive attack. This gives the user a good defensive Quirk, taking whatever their opponents can dish out and throwing it right back at them. Though there is a limit on how much the user can coil up, an attack can overwhelm and damage them. The Quirk cannot defend from non-direct attacks, and the user needs to aim their body to counter the attack, allowing foes to harm them.
