Invisibility

Harry Potter can wear his invisibility cloak to hide his presence.

Background

Invisibility is the ability to render oneself unseen to the naked eye. The user can move about an environment unnoticed and act without being observed. This may extend to other objects, creatures, or even entire areas.

The mechanism behind Invisibility varies by setting. It may be optical (bending light around the user), perceptual (making others unable to notice the user), technological (using cloaking devices), or magical (using spells or enchanted items). Some users can choose to let certain people see them while remaining invisible to others, while others may be unable to control who perceives them.

Invisibility is distinct from Intangibility, which normally involves passing through objects, and from Stealth Mastery, which involves remaining undetected through skill rather than supernatural means.

A similar ability to this is Camouflage, the ability to effectively appear invisible by matching with the environment.

Also Called

• Cloaking
• Concealment
• Transparency
• Vanishing
• Unseen

Possible Applications

• Moving through areas without being seen
• Avoiding detection by visual observation
• Hiding objects, creatures, or areas
• Choosing specific individuals who can see the user
• Extending invisibility to objects or people the user touches
• Creating areas of invisibility
• Combining with other stealth abilities

Practical Uses

• Stealth Operations: The user can move through hostile areas, bypass security, or observe without being detected.

• Evasion: The user can escape pursuit by becoming invisible and disappearing from sight.

• Surveillance: The user can observe others without being seen, gathering information without detection.

• Infiltration: The user can enter restricted areas or pass through checkpoints without being noticed.

• Object Concealment: The user can hide important objects or weapons by making them invisible.

• Protection: The user can make allies invisible to hide them from threats.

Example Variations

• Optical Invisibility: Light is bent, refracted, or absorbed around the user, making them visually undetectable. Physical presence remains — the user can still be touched, heard, or detected by other means.

• Perceptual Invisibility: The user is not physically invisible, but observers are unable to notice them. Their mind either fails to register the user's presence or rationalizes it away. This may be selective.

• Technological Invisibility: The user uses a device, suit, or technology to achieve invisibility. This may have limited duration, power requirements, or failure states.

• Magical Invisibility: The user uses magic to become invisible. This may be through a spell, enchanted item, or innate magical ability. It may require concentration or have other magical limitations.

• Selective Invisibility: The user can choose who can see them. They may be visible to allies but invisible to enemies, or vice versa.

• Extended Invisibility: The user can extend their invisibility to objects they touch, people they are near, or areas they designate.

• Partial Invisibility: The user can make only parts of their body or only certain objects invisible.

Possible Limitations

• The user may not be able to make clothing or equipment invisible along with themselves
• The user may have a time limit on how long they can remain invisible
• The user may require concentration to maintain invisibility
• The user may still be detectable by other means (sound, smell, heat signatures, touch)
• Some opponents may have abilities to see invisible beings
• The user may be unable to revert to a visible state, or may be trapped invisible
• The invisibility may not function in certain environments or under certain conditions
• Extended invisibility may have costs or side effects

Distinction from Related Abilities

• Stealth Mastery: Stealth relies on skill and technique to avoid detection; Invisibility is a supernatural or technological ability.
• Intangibility: Intangibility allows passing through objects; Invisibility only conceals visual presence.
• Illusion Manipulation: Illusions create false images; Invisibility removes the user's image entirely.
