Background

Chen Hao awakens alone in a primeval forest and realizes that he has transmigrated into the Dragon Ball world. A Sign-in System offers him several possible identities, and he decisively selects Super Saiyan 4. 1 2

On his first check-in, the system grants him unrestricted Instant Transmission and a tenfold training-speed boost. After sensing Android 18 being attacked by Cell, he teleports to the battle south of Turtle Hermit Island. 3

He saves Android 18 by overwhelming Cell, then defeats Vegeta's attempted attack without difficulty. Though he initially operates alone, Android 18 chooses to follow him after he leaves to train, and Chen Hao accepts her companionship under strict conditions. 6 7 10 14 15

After defeating Perfect Cell, Chen Hao helps restore Android 17 using Dr. Gero's research data and a medicine that repairs his damaged energy circuits. 32 34 35

Three years later, Chen Hao remains unable to surpass full-power Super Saiyan 4. Whis's arrival—and Beerus's interest in his unusual power—pushes him to seek a faster path to strength. He travels with Android 18 to Supreme Kai's World, obtains and destroys the Z Sword, and releases Old Kai. 41 43 44 45 48

Appearance

Chen Hao normally has black hair and wears martial arts clothing. His transformed appearances vary sharply by form, particularly his Super Saiyan 4 state. 14 31 32

Personality

Chen Hao is composed, self-assured, and often deliberately provocative toward opponents. He taunts Cell, dismisses Vegeta's status as Saiyan prince, and remains calm even when facing overwhelming threats. 7 20 25 43

His ambition is central to his decisions. Despite defeating Perfect Cell effortlessly, he insists that stronger beings exist and refuses Trunks's lucrative offer because he intends to pursue higher realms of power. 32 34 40

He can appear cold and transactional, especially when Android 18 asks him to rescue Android 17. However, his conduct consistently shows restraint and concern: he spares Vegeta, protects Android 18 in battle, repairs Android 17's circuits, and warns Android 17 not to mistreat his sister. 10 17 20 35 36
