In 2035 on the dystopic Tinos planet, we meet a youth named Blue who is tricked by a police officer into committing murder and is then executed on the spot. However, Blue had just made friends with a 300-years old machine known as Fatso, who decides to revive him as an extraordinary cyborg. By receiving Fatso's knowledge and memories, Blue realizes the roots of the evil plaguing Tinos go much deeper than the crooks who had him killed and sets out to decide the fate of the galaxy itself.
The series had a 2011 Continuity Reboot called Cyber Blue - Ushinawareta Kodomo-tachi which got a 2012 sequel called X Battlers - Cyber Blue the Last Stand.

- Cluster F-Bomb:
- Blue is fused with a foul-mouthed robot named Fatso and frequently tells enemies to fuck off.

Fuck you, bastard!!"
- While dismantling the bad guys' operations, Blue asks Alan to write a graffiti message to let them know what happened. But Alan is illiterate, so he just writes "Fuck You" in every location they destroy instead.
- The extra pages of volume 3 portray a "battle" between Blue and Gaza that is just Blue shouting "FUCK YOU!" and Gaza screaming in a panic.

- Blue defeats and spares Joe-K, realizing he's a noble guy at heart. In return, Joe comes to his aid in later battles.

- Defector from Decadence: Stan was one of the five founders who made a plan to take over the Earth, but he grew to fear the consequences and set up a plan for Fatso to eventually stop the war against Earth before it begins.
- Die Laughing: Joe-K remarks that he has never laughed because on Sieg, laughing is everyone's last words. He laughs his own defeat off as he attempts to detonate on Blue. When he's killed by Galgo, Joe sheds tears over his opponent's tragic circumstances, but passes away with a laugh.
- Disproportionate Retribution: One old man who told stories of Earth to a young Blue is executed by the authorities for "talking about love and hope when he doesn't understand what they really are".

- Got the Whole World in My Hand: The cover for chapter 19, in which Blue travels to the Earth, shows him holding it over his hands.
- Guns Are Worthless: Blue starts out as a gunslinger, but the story gradually shifts to him having to fight at close range with martial arts and exotic techniques.
- Hair Color Dissonance: Blue has black hair in some illustrations and blonde hair in others.
- Half the Man He Used to Be: Blue breaks the Doberman Bio-being over his back.
- Harmful to Minors: The story has a couple of child deaths early on to give an impression of the setting and the most callous villains in it are those willing to kill children.
- Heroes Prefer Swords: Blue converts a tool meant to fight the bio-beings into a more powerful sword.
- Improbable Aiming Skills: Blue was a very skilled gunslinger to begin with, but after his transformation he becomes able to kill snipers from far away and shoot down enemies who are hiding in crowds. At one point he even wields a machinegun like it is a nunchaku!
- Kindhearted Cat Lover: Shila dies protecting her pet cat which was a memento of her dead lover who Gaza has killed.

- No Celebrities Were Harmed: Gaza is designed after Prince.
- Non-Action Big Bad: Gaza ultimately doesn't fight at all and is killed like a chump when his attempt to absorb the ultimate life form backfires since Lonnie had gained full control over it.
- Not So Stoic: Blue is generally stone-faced like the Kenshiro look-a-like he is, but he's willing to crack jokes in his interactions with Earth Federation agent Clare.
- When they first meet:
Clare (to Alan): Don't be impudent with me, you 17-year old brat! I'm six years older than you!Blue: That's wrong, I'm 294 years older than you, baby!- When they meet in a fancy restaurant:
Alan: Whoa, pretty! (turns to Blue) ...T-this is when you're supposed to praise her.Blue: Your internal organs have no abnormalities; you should be able to live for at least another 50 years. - The Obi-Wan: Fatso and Stan exist within Blue's mind and give him advice or talk through him from time to time. Blue is later able to project them to let them talk to other people.
- Oh, Crap!: Blue finds a robot hiding inside a crucified Jesus statue and thinks it is easy pickings. Then he scans it...
- Powered by a Forsaken Child: Galgo and the other bio-beings are conveniently powered by the genes of Lonnie, a childhood friend of Blue's. The villains want the boy fused to a creature who feeds off other life forms, so then Gaza can take control over it and become immortal.
- Rapid Aging: Blue becomes an adult when Fatso passes on his 300-years worth of painful memories.
- Rapid-Fire Fisticuffs: Aside from the aforementioned Salamander machine gun. Blue used the traditional technique against Galzo during the final battle.
- Rated M for Manly: The story is a pastiche of extremely manly Hollywood action movies. The opening page alone is of a Blue armed to the teeth like he's Rambo or something.
- The Reveal: The past of Tinos and what the Noel oath was.
- All the people who were sent from Tinos to Earth are under a mind-controlling trigger to start a war and conquer the planet.
- Tinos was never a nice place to begin with. It was a barren planet where the founders had to fight against aliens for the profit of the Earth government... only to realize the aliens were actually human rebels and it was all a set up.
- One of the founders is Blue's distant ancestor. Fatso had been tasked to combine with Blue to begin with and prevent the Noel Oath from coming to pass.
- Reused Character Design:
- Blue is just plain old Kenshiro... as a foul-mouthed T-800!
- Likewise, Joe-K resembles Shin.
- Scenery Porn: Several chapters end with a shot of some scenery, which sometimes sets the stage for the next chapter.
- Shoot the Bullet: Blue's first move against Joe-K is shooting down the two rockets he fires.
- Sir Swears-a-Lot: In something of an oddity for a 300-year old robot, Fatso frequently spouts Gratuitous English swears. Even after fusing with Blue he'll occasionally bad guys a piece of his mind before blowing them to pieces.
- Tag Along Kid: Blue's brother Alan is this to him, if only because Blue aged a few years during his rebirth. He never gets to show any battle prowess at all.
- Taking You with Me: Joe-K attempts to self-destruct on Blue when defeated, but Blue swats the bomb away and spares his life.
- Technobabble: Lonnie and the bio-beings' powers come from "the energy of imaginary numbers, Shadow Force".
- Token Motivational Nemesis: The corrupt police officer Weiser slaughters Blue with his minions, leading Fatso to revive Blue as the ultimate life form. Blue then manages to kill Weiser just a couple chapters later, noting his real enemies are elsewhere.
- The Worf Effect:
- At one point Joe-K is beaten up offscreen by some random dude who then gets instantly killed by Blue without getting to do anything.
- Joe-K is easily defeated by Galgo when he was protecting an African president, as the first display of the villain's abilities to readers. At the end, Joe-K far too easily dies by Galgo's hand, and he only gets one hit in because the lion warrior sympathizes with him.
- X Meets Y: This is Fist of the North Star meets The Terminator and a bit of RoboCop sprinkled in.
