The article explores the growing phenomenon of therians, individuals who identify with animals and express this identity through various means, including wearing animal masks. Experts are increasingly worried as this trend, which is proliferating particularly on TikTok, may lead to self-harm or harm to others. Historically, therians have existed since the 1990s on online forums, but the current surge in visibility marks a significant change in how these identities are perceived in society. Recently, a large gathering was held in Buenos Aires, Argentina, where numerous individuals identifying as therians congregated in a public park, indicating both a community aspect and the risks involved.

The resurgence of therians is not entirely new, as the concept of theriantropy has roots that date back decades. The term itself comes from the combination of Greek words that translate to "beast" and "man", indicating that these individuals do not simply role-play but feel a deep, intrinsic connection to the animal they identify with. This connection raises important discussions about mental health, social acceptance, and the boundaries of identity in a modern context, particularly as the phenomenon gains viral traction.

As the online community of therians grows, it poses unique challenges, not only for those involved but also for society at large. Concerns about potential self-harm and aggressive behavior associated with some individuals in this group highlight the need for better understanding and support mechanisms. The article prompts us to consider the implications of identity in the digital age and the responsibilities that come with the freedom of self-identification in an increasingly connected yet complex social landscape.
