Unstoppers

Unstoppers are a fictional concept often found in speculative fiction, particularly in stories involving superpowers or advanced technology. The term generally refers to individuals or entities that are exceptionally difficult, if not impossible, to stop or contain. This could be due to a variety of reasons, such as immense physical strength, extraordinary speed, an ability to phase through matter, invulnerability, or a relentless will. In some narratives, an "unstoppable" force might be pitted against an "immovable" object, creating a classic philosophical paradox.

The concept of an unstopppers is frequently used to raise the stakes in a story, presenting a formidable challenge for the protagonists. Their nature can range from a singular, powerful villain to a pervasive force like a plague or a natural disaster that cannot be averted. The narrative often explores the implications of such an unstoppable force, including the futility of resistance or the desperate search for a unique weakness. The very definition of "unstoppable" can be subjective within a given fictional universe, with characters or plot devices sometimes finding ways to circumvent or neutralize what was initially thought to be insurmountable.
