Quirk- Ocean Terror
Type- Mutation/Transformation
Description- Ocean Terror is a unique and dangerous mutation/transformation quirk that allows the user to transform into a terrifying creature reminiscent of deep-sea creatures. When activated, the user's body changes both physically and internally to resemble a combination of various deep-sea animals, such as sharks, anglerfish, and squids.

Abilities:
- Enhanced Strength: The user's transformed body gains significant strength, allowing them to overpower opponents easily.
- Enhanced Speed: They become incredibly agile, capable of swift movements both underwater and on land.
- Underwater Adaptation: The user gains the ability to breathe underwater and is resistant to extreme water pressure, allowing them to explore ocean depths without any issue.
- Camouflage: The user's bioluminescent patterns can adapt to their surroundings, allowing them to blend in seamlessly. This ability is especially useful in the dark depths of the sea.
- Aquatic Communication: The user gains the ability to communicate with marine animals telepathically, forming a bond and commanding them.

Weaknesses:
- Land Mobility: Despite their enhanced abilities, the user's transformed body is less efficient on land due to their adapted physiology for underwater movement. They might experience difficulties running or traversing uneven terrain.
- Water Dependence: To maintain their transformed state, the user requires a constant supply of water. If deprived of water for an extended period, they will revert to their normal form.
- Vulnerability to Electricity: The user's bioluminescent patterns are sensitive to electrical impulses, making them vulnerable to electric-based attacks or shocks.

Overall, the Ocean Terror quirk provides a wide array of capabilities, enabling the user to dominate underwater environments and strike fear into their enemies. However, it also comes with limitations and weaknesses that need to be carefully managed for optimal effectiveness.

When the user of the Ocean Terror quirk is on land, they can selectively utilize certain aspects of their transformed form to enhance their physical capabilities. These additional abilities can be unlocked based on different deep-sea creatures they embody during their transformation.

Examples of enhanced capabilities on land include:

- Leviathan's Brute Strength: By activating the enhancements derived from Leviathan, the user's strength is further amplified, allowing them to possess incredible power and deliver devastating blows. They can perform feats of strength like lifting heavy objects, breaking through barriers, or overpowering opponents with sheer force.

- Umibozu's Stealth: Drawing upon the abilities of Umibozu, the user gains enhanced stealth and agility on land. They can move silently, blend into shadows easily, and traverse urban environments with remarkable grace and precision. This makes them very effective in covert operations or stealthy engagements.

These selective enhancements not only provide the user with advantages during land-based confrontations but also add versatility to their overall capabilities. It allows them to adapt to different situations and maximize their effectiveness both underwater and on land.

Physical Changes:
- The user's eyes undergo a mutation, resulting in two unique eyes. These eyes have a distinctive appearance and possess the ability to illuminate in the dark. When activated, the user's eyes emit a faint bioluminescent glow, granting them perfect night vision. This allows them to see clearly in complete darkness, giving them a significant advantage in low-light or nocturnal environments.

- Additionally, the user develops strange markings on their upper arms. These markings could either resemble intricate patterns similar to those found on deep-sea creatures or be bioluminescent in nature, emitting a soft glow. While their exact purpose remains unknown, these markings may serve as an additional visual signal or have a specific function related to the quirk's abilities.

With the added ability of perfect night vision, the user becomes even more proficient at navigating in dark conditions, whether on land or underwater. This enhanced visual capability allows them to detect minute details, spot hidden enemies, and maneuver effectively in situations that would normally be challenging for others.

Here are some potential drawbacks that the user of the Ocean Terror quirk may experience:

1. Comatose State: After utilizing their quirk to its fullest extent or during intense battles, the user's body can enter a deep coma-like state for a week. This renders them completely unconscious and vulnerable, which can be problematic if they are in a dangerous environment or require immediate assistance.

2. Emotional Backlashes: The transformation and use of the Ocean Terror quirk can take a toll on the user's mental well-being. They may experience high anxiety due to the immense power they possess, constantly worrying about losing control or causing unintentional harm. Additionally, they may develop phasmophobia, an irrational fear of spirits or supernatural beings, which can be triggered by the monstrous aspects of their transformed state.

3. Eating Disorders: The user may struggle with eating disorders due to the strain the quirk places on their body. They may have difficulties maintaining a regular and healthy diet, leading to issues such as anorexia or binge-eating, which can further affect their overall health and performance.

4. Major Depression: The burden of having such a unique and potentially dangerous quirk, coupled with the physical transformations and associated drawbacks, can lead the user to experience bouts of major depression. They may feel overwhelmed, isolated, or struggle with a sense of purpose, requiring support from friends, family, or professional help.

These drawbacks add complexity to the Ocean Terror quirk and highlight the toll it takes on the user's physical and mental well-being, emphasizing the challenges they face in harnessing their power effectively.
