강한 가수 (Gang-han Gaseu) - This name literally translates to "strong singer." While not a single word name like many traditional Korean names, it directly conveys the desired meaning and sounds natural in Korean. The use of 강한 (Gang-han) emphasizes strength, while 가수 (Gaseu) clearly indicates a singer. This option is suitable if a direct and easily understood meaning is prioritized.

서은 (Seo-eun) - This name uses the characters 서 (Seo), meaning "west" or "clear," and 은 (Eun), meaning "silver" or "grace."

예진 (Ye-jin) - This name combines 예 (Ye), meaning "beautiful" or "art," and 진 (Jin), meaning "truth" or "genuine." The combination implies a singer who is both beautiful and authentic, suggesting strength through artistry and sincerity. This option offers a more subtle approach to conveying the desired meaning.

수아 (Sua) - This name means "water" or "graceful," and while not directly related to "powerful singer," the imagery of water, which can be both gentle and powerful, can be interpreted metaphorically. The name is short, sweet, and popular, making it a good choice if a more concise and common-sounding name is preferred.

소현 (So-hyun) - This name combines 소 (So), meaning "small" or "ox," and 현 (Hyun), meaning "bright" or "present." While seemingly contradictory, the combination can be interpreted as a powerful singer who possesses a humble and bright spirit. The name has a classic and elegant feel.
