A person who uses their power, often in a manipulative or unethical way, can be referred to as an "abuser of power" or a "power monger." In some contexts, terms like "tyrant" or "oppressor" may also apply, especially when their actions lead to the exploitation or control of others. Alternatively, if the power is used positively, such a person might be seen as a "leader" or "influencer."
