The Ultimate Transformation Device: Embrace Your Inner Hero or Creature with Ease

Question: Write a concept for a hand-held or watch device that allows anyone wearing it to painlessly and instantly turn into any animal or any fictional character/creature from movies, TV shows, games, books, etc (without the need for holograms or something like that), but still retaining their personalities and memories (while also gaining every powers from the characters as long as they do not harm or destroy Earth). The reader could have an option to keep their normal voices or change their voices to match the characters they have transformed into. For non-verbal characters or creatures such as, but not just dogs or other non-talking animals, the users would retain their ability to speak and with their voices (although they could now also communicate as the animals they have the forms of), so the other people can understand that these "talking animals" are actually people who use the transformative devices (plus, the users in bodies in herbivore, carnivore, or insectivore bodies could still retain their human forms' omnivory, so they don't have to worry about having to hunt prey nor only eat plants). For the users in real animal forms, they can transform into any animal (for the animals with gills, such as fish, they could still breathe air so the users in those forms don't need water to breathe; for cold-blooded animals like lizards, the users in cold-blooded bodies would still be warm-blooded so they don't have to worry about needing heat or sunlight to be active; and for arthropods or other invertebrates with booked lungs, the users in those bodies could have modified respiratory systems to allow normal breathing for the users just for comfort, and have a size option to allow the users to still be human-sized or anything smaller than a man, but not smaller than that respective invertebrate the users are in the form of). The users can also transform into any real extinct animal, either the real and accurate ones or inaccurate/pop culture/documentary ones, depending on the user's preference (for example, but not limited to that, the user can chose to turn into a real/accurate Velociraptor that is turkey-sized, feathered, have supinated (non-pronated) hands and no shrinkwrapping, or chose to turn into an inaccurate Jurassic Park-styled Velociraptor that is man-sized, scaly, have pronated hands and shrinkwrapping). Note that these devices have an option to have the transformation permanent or temporary (but still able to go back to those forms if the user's transformation is temporarily), but beware, the user could be stuck as a character or animal/creature forever (permanent and irreversible) if they confirm the transformation to be permanent.
