Devil Fruit: Voice Voice Fruit (Koe Koe no Mi)

Type: Paramecia

Ability Description: The user can manipulate their vocal chords to produce sound waves that have a strong suggestive effect on the minds of anyone who hears them. They are most effective on a willing recipient of the effect, and they get less and less potent if the listener’s mind is strong and unwilling to comply. At stronger stages, the user can produce powerful sounds, capable of producing sonic shockwaves to destroy physical objects, high pitches that can injure ears and deafen listeners, and even more powerful suggestions that can push a human body to perform an action otherwise impossible.

Progression: Stage 0 – The user can vocalize minor suggestions, making enemies freeze in their tracks or briefly consider not following through with their previous decisions and actions. On an ally the effect is stronger, boosting their physical prowess depending on the command given. The user cannot fully control their power and will sometimes accidentally speak a command or even become confused by the suggestions of their own voice.

Stage 1 – The user’s basic commands become harder for enemies to resist, and they can even start attempting more potent commands like making someone feel fatigues, sleepy, or feel an emotion they otherwise were not naturally feeling. Allies can be further manipulated to do things they normally couldn’t, to fight stronger, move quicker, and other physical feats. The user will almost never accidentally discharge a vocal command anymore or be affected by their own voice.
At this stage, the user can use a physical vocal attack for the first time, a small sonic blast around their body. It has almost no offensive use, but the user can soften the blow of some physical attacks and attempt to deflect small projectiles.

Stage 2 – The user’s vocal abilities are extremely potent against enemies, and any who hear their command will have to fight hard to resist their call. Simpler physical commands become almost impossible to resist, and now more extreme ones become slightly viable, such as putting someone to sleep, forcing them to attack their own allies, and otherwise rendering them useless. Allies can be affected to stand up when their bodies should be completely fatigues, and the user can even command them to stop being tired, regenerate quicker, or ignore other negative physical effects on their bodies.
At this stage, the user can now use sonic blasts in a small projectile from their voice to destroy weak objects and knock away projectiles and enemies, although the destructive power is still very low at this level. It can begin to deafen enemies and prevent them from hearing other important sounds around them.

Stage 3 – The user’s vocal commands become incredibly potent and dangerous at this stage. Enemies can almost never resist the commands from previous stages, and the user can now attempt more extreme commands such as stopping their breathing, heart beats, and other bodily necessities. The user can turn enemies against their own and even give them “sleeper” commands that can be activated with another word or phrase at a later time. Lastly, the user can just barely begin to do powerful mental maneuvers in their enemies, such as making them remember false statements or forget truthful things with a command. The user can turn allies into near superhuman puppets by commanding them to ignore their bodies’ natural inhibitors to increase their strength, speed, and other physical characteristics no matter how much damage they have taken.
At this stage, the user’s voice is a potent physical weapon as well. Sonic screeches can deafen enemies with stunned eardrums, and the shockwaves can shatter wood and some metals. Sonic shields can defend from attacks and shred direct attackers and the ranged blasts are as potent as a cannonball if they strike a living person directly.

Stage 4 – The user’s voice is an all-powerful decree. Enemies bow before nearly anything the user speaks, and they can almost freely manipulate the mind of those who hear their commands. The user can force even permanent commands on some enemies and turn someone into a mere puppet. Allies can perform physical feats beyond anything their body could naturally achieve and can rise from any wound in battle to continue fighting at maximum efficiency regardless of stamina and injury. The most powerful ability of this stage is commanding someone to die, and even a powerful, strong-willed opponent will be shaken to their very core trying to resist the urge to obey.
At this stage, the user’s voice is almost as physically powerful as it is mentally. The user’s sonic screams can become impenetrable shields that will rip apart direct attackers. Powerful sonic blasts emanate from the user like an explosion originating from where they stand. The user’s ranged sonic blasts can rip through nearly any material and defense and should be avoided at all cost.
