Lin Ling

Before becoming the new Nice, Lin Ling had dark brown hair and dark eyes, and her complexion was darker than Nice's; in addition, her voice was higher-pitched than Nice's.

Since he had a facial structure similar to Nice's, he was allowed to live and, in turn, become the next Nice. By gaining the trust of his fans, his appearance and body would transform into Nice's, making him practically an exact copy of Nice.

Although the personality of the previous Nice is unknown, Lin Ling is shown to be a tireless worker and a staunch defender of superheroes, so much so that she compares Moon to a goddess. Even after facing her first supervillain, she demonstrated her innate heroism by defeating her former boss and even trying to calm him down in the midst of battle.

Although unknown, Prior Nice appears to have suffered from depression and extreme stress, as seen in his suicide and the manager's comment to Lin Ling at the end of Episode 1, likely hinting at the fact that those who assume the role of Nice must deal with the pressure of both public trust and the darker side of heroism.

Confidence: Confidence is the power source that fuels the powers in the Hero X universe. Therefore, individuals like Nice are strengthened by the confidence of others. Because of this, the more public trust they gain, the stronger they become. Confidence also demonstrates the ability to alter one's appearance to match the vision of those who trust them, as seen when Lin Ling, who already resembled Nice before the original suicide, changed her hair, eyes, and voice to those of the former after gaining the trust of her fans.
