"OP" stands for "Overpowered," a term commonly used in gaming, anime, and other media to describe a character, item, or ability that is significantly stronger than others. This can lead to an imbalance in gameplay or storytelling, making challenges too easy or predictable. In many cases, an overpowered character can defeat opponents without much effort, which may reduce the excitement and tension in a narrative. Developers and writers often strive to balance these elements to maintain engagement and ensure that challenges remain meaningful for the audience.
