What is the result of completely overpowering an opponent?

The term "vanquishing" refers specifically to the act of defeating or overpowering an opponent completely. It connotes not just a win, but a decisive and overwhelming victory over someone or something, indicating that the opponent has been completely subdued or overcome. This word is often used in contexts like competition, battle, or any situation where one party triumphs over another.

The other options do not convey the same meaning of overpowering an opponent. For instance, "succumbing" implies yielding to an opponent, which is the opposite of overpowering. "Terminating" suggests ending something, which does not necessarily relate to defeating an opponent. "Truncating" means to cut something short, lacking any context of conflict or competition. Thus, "vanquishing" stands out as the term that accurately captures the essence of overpowering someone in a confrontation.
