Official Introduction
"The Starlight Knights never lose!" — Billy Kid
This handsome cyborg with a cool and carefree personality is an avid fan of the Starlight Knight show, not only referring to himself as one of the Starlight Knights, but repeating many classic lines from the show.
He may look unreliable, but once he gets serious, Billy can take on any challenge...
He seems carefree, but his strength can be relied on..
Hahahaha! This is the power of the Starlight Knights!
As usual, you take the front, I'll provide fire support from behind!
Profile
"The White Chariot" of the Cunning Hares and Former "Red Scarf" of Calydon, Billy Kid is an Intelligent Construct made for combat. Despite having a childish personality and fascination for the TV show Starlight Knight and the idol Monica, Billy is a skilled and powerful fighter, having once been an Outer Ring Champion and being able to outmatch Lighter in a fistfight.
Armed with a pair of revolvers, Billy fights countless threats inside Hollows as part of his job, though he does have a tendency to forget his ammo count.
History
Found in the Outer Ring's Lost Tech Ruins by a young Appon and his mentor,[1] this Intelligent Tactical Unit (or Battle Android) would roam with these drifters until being sold to the leader of "Calydon," who gave him the role of champion and a name: "Billy Kid." Billy's time as the "Red Scarf"[2] of Calydon made him infamous, with thugs cowering in fear upon hearing his name, earning him the name of "Calydon Reaper". He also became close with fellow member Big Daddy and his owner's daughter Caesar King, the latter whom he called "Big Sis."
When Calydon's leader vanished and the gang split, Billy would stay with Big Daddy and Caesar, his spare arm becoming a prosthetic for the latter, who lost her left arm during the chaos.[3] With his owner gone, Billy was an aimless combat weapon once more. After a discussion with the recently formed Sons of Calydon, they decided to let Billy leave. Before his departure, he would form a close bond with Lighter, his successor-to-be. Billy also received two guns from a friend before he left.
With a taste of freedom, Billy ventured to New Eridu, making the city his new home. By some "weird twist of fate," Billy ended up with the Cunning Hares,[4] and in turn became a close ally to the Legendary Proxy Phaethon, assisting them countless times during the story. During the events of New: Eridan Sunset (B), Billy, with money from Nicole, was able to buy some modifications that would transform him into something like a Starlight Knight.[5]

Agent Details
Billy Kid, an AI construct that has passed the forbidden fruit test, is essentially a self-aware machine.
True to his name, despite having the appearance of a robot, he is quite childlike.
He's a big fan of the visual FX show "Starlight Knight" and wishes to be a hero like the main characters of the show. He often refers to himself as a Starlight Knight and imitates the lines in the show.
Such behavior appears to be only for comedic effect, however.
"Don't make me sound like an idiot! I'm obviously very smart!" — Billy.

Trust Rank: Close
Similar to Anby, there are gaps in Billy's personal history that remain unfilled.
The available information indicates that before joining Gentle House, Billy spent an extended period serving with another mysterious gang.
As of now, it appears Billy still maintains a close connection with a certain gang leader from the Outer Ring of New Eridu.

| Weren't you obsessed with the Starlight Knight series as a kid, Wise? That brings me back. You shouting "Starlight Mirage!" with your arms crossed... | |

| There was never such a time. Please erase such non-existent memories from your mind. It's been a long time since I was that age, after all, and my name doesn't have "kid" in it. |
