Nice is a major character in the donghua series To Be Hero X. He is publicly known as the tenth-ranked hero and is widely celebrated as the Perfect Hero, a manifestation of the ideal hero as imagined by the people. His background is marked by a sharp contrast between his flawless public image and his private reality. Early in the series, Nice commits suicide by jumping from a rooftop, an event witnessed by a young man named Lin Ling. Lin Ling is subsequently forced by Nice's manager to assume the identity of Nice, effectively taking over the hero role and inheriting the powers associated with the name. The Nice identity is therefore not tied to a single individual but is a persona that can be passed on, with the powers sustained by public trust and belief.

In terms of personality, Nice outwardly projects charisma, bravery, elegance, and selflessness. He brings the grace of a ballerino to his battles, mesmerizing audiences with flawless movements. Privately, however, he is deeply troubled. He is obsessive about maintaining his top ranking and is willing to perform morally questionable acts to achieve his goals. He struggles with inner turmoil and a fear of inadequacy, which fuels his drive for perfection. His public facade cracks under pressure, revealing a more vulnerable and desperate individual.

Nice's primary motivation is to be the perfect hero and to secure the highest possible trust value and ranking. He craves public adoration and validation, and this need consumes him. He is willing to do whatever he deems necessary to fulfill his goal, including engaging in dirty work behind the scenes.

His role in the story is complex and pivotal. He appears in minor yet crucial roles in the first and final arcs, and he serves as an antagonist in the seventh, eighth, ninth, and tenth arcs. His early death sets the entire first arc in motion, as Lin Ling is forced to take his place and navigate the world of heroes under the false identity. Nice's legacy and the nature of his identity haunt the narrative, raising questions about authenticity, heroism, and the cost of public trust.

Key relationships include his connection to Lin Ling, who becomes the new bearer of the Nice identity. There is also a relationship with Moon, a hero who was dating Nice at one point. Nice's manager is another significant figure, as it is the manager who orchestrates the cover-up of Nice's death and forces Lin Ling into the role.

Character development is explored primarily through the contrast between the public perception of Nice and the private reality of the person behind the mask. The series examines how the pressure of being a perfect hero can destroy an individual. The character's development is also reflected in Lin Ling's journey as he grapples with living up to the legacy of the name while dealing with the original Nice's unresolved issues.

In terms of notable abilities, Nice possesses powers that are fueled by public trust, as is the case for all heroes in this world. He can fly, but this ability is contingent on his fans believing he should be able to go somewhere. He also has enhanced strength and endurance beyond that of ordinary people. His fighting style is elegant and dance-like, incorporating ballet-inspired movements that make his combat appear like a performance. His signature approach is described as no less than a flawless dance and a flawless victory, befitting his title as Mr. Perfect. The powers of Nice are tied to the identity itself, meaning that anyone who assumes the name and is accepted by the public can wield the same abilities.
