Background / History

Zhou Zilong transmigrated into the Dragon Ball world and quickly recognized its extreme dangers and power gaps. On his first day, he interrupted Bulma's kidnapping and escorted her to Capsule Corporation, where contact with Bulma activated the Dragon Ball Fantasy System. He named its AI companion Xiao Ling. 1 2

Dr. Brief hired Zhou as Bulma's bodyguard for 100,000 Dragon Coins per hour and allowed him to remain at the Brief residence. There, Zhou completed his first marrow cleansing, gained several extraordinary abilities, and began studying science under Dr. Brief. 3 4

Using his enhanced intellect and Capsule Corporation resources, Zhou built a gravity chamber capable of one to one hundred times normal gravity. After reaching a training bottleneck, he left West City to become Master Roshi's third disciple, securing his acceptance by creating the lifelike robot Mei Hui. 4 5 6

Following Turtle School training and the destruction of the Predator Mercenary Group, Zhou completed Roshi's curriculum and continued seeking stronger mentors. His final marrow cleansing changed his race to Saiyan and granted him a modified Legendary Super Saiyan bloodline. Xiao Ling later supplied him with an implanted identity as Broly: a Saiyan exiled by King Vegeta whose malfunctioning spacecraft landed on Earth. 15 16

Zhou subsequently trained with Korin, the Guardian of Earth, and North Kai. He used the Hyperbolic Time Chamber, learned Kaioken, and developed a spatial teleportation technique from the Space Cultivation Law before returning to Earth ahead of the Dragon Ball quest. 17 18 21

Appearance

Following his Saiyan marrow cleansing, Zhou is 1.89 meters tall and weighs 87 kilograms. His cleansing also gave him a brown-black Saiyan tail approximately 85 centimeters long and a hairstyle compared to Gogeta's. 15 41

• Originally described as tall and handsome. 2
• Developed a stronger, more muscular build and bronze-toned skin after obtaining his Saiyan bloodline. 15
• Wore a black bodysuit during the assault on the Predator Mercenary Group. 13
• Later created a black-and-red combat suit with red-and-black boots, gold blade-like toe details, and gold rings around the boot tops. 41
• In his Great Ape Power transformation, reaches 2.07 meters and 101 kilograms. 50

Personality

Zhou is intensely driven to become stronger, but frames that goal around protecting the people close to him and preventing threats to Earth. He intervenes against the Predator Mercenary Group, protects Bulma from the Scale-Head Clan, and seeks greater training whenever he identifies a gap in his strength. 10 18 44

He is also practical and resourceful. Rather than relying only on martial arts, he studies science, builds training equipment and robots, establishes businesses to fund the system, and plans carefully around the risk of attracting Frieza Force attention. 4 6 21 45

Despite his overwhelming strength against many opponents, Zhou generally suppresses his aura and avoids revealing his full power unnecessarily. His confidence can become openly dismissive when facing clearly weaker enemies, as seen in his encounter with Yamcha. 10 30
