Domination-Domination Fruit: This Paramecia-type Devil Fruit grants the user the power to completely dominate and control the will of others, influencing their actions and thoughts subtly or overtly. The user could subtly sway opinions, force obedience, or even completely control a person's body, depending on their level of mastery. The range of influence might initially be limited, requiring close proximity, but with training, the user could potentially extend their control over vast distances or even influence entire crowds. Weaknesses could include a strong-willed individual resisting the influence, or the user's own mental state affecting their control (stress, fatigue, etc. could weaken their abilities). Advanced techniques could involve creating illusions or manipulating memories to further their control. The fruit's name reflects its core ability: complete domination.

Manipulation-Manipulation Fruit: This Logia-type Devil Fruit grants the user the ability to manipulate and control various forms of energy, including but not limited to kinetic energy, thermal energy, and even potentially mental energy. The user could accelerate or decelerate objects, generate intense heat or cold, or even manipulate the flow of information within a person's mind (though this would likely be a more advanced technique). The user could transform their body into pure energy, becoming intangible and highly mobile. Weaknesses would include vulnerability to attacks that disrupt energy flow (such as powerful electromagnetic pulses) and the potential for energy overload if the user attempts to manipulate too much energy at once. The fruit's name reflects its ability to manipulate various forms of energy and potentially even manipulate information and minds.

The "Dominant-Manipulative" Combination Fruit: This hypothetical combination fruit would blend the powers of both the Domination-Domination and Manipulation-Manipulation Fruits. The user would possess both the ability to dominate the wills of others and the ability to manipulate various forms of energy. This combination would create a powerful and versatile ability set. The user could, for example, dominate an opponent's will while simultaneously manipulating their kinetic energy to render them immobile or even inflict harm. They could manipulate the thermal energy around an opponent to create debilitating heat or cold, while simultaneously influencing their thoughts to make them more susceptible to the effects. The weaknesses would be a combination of the individual fruit weaknesses, meaning a strong-willed individual might resist the domination, and energy-disrupting attacks would still be effective. However, the combined power would make this a highly dangerous and versatile Devil Fruit. The name could be something like the "Overlord Fruit" or the "Absolute Control Fruit," reflecting the ultimate power over both mind and energy.
