Robo-Weapon is a semi-major antagonist in The HV and Dino-Weapon Show. He is often considered a minor character, but according to Dino-Weapon and The Editor, he is one of the most powerful and dangerous characters on the show. He was first mentioned in the third Run 3 video on the channel, where Dino calls him an actual demon. He made his debut appearance in the video titled "ROBO-WEAPON IS HARDER THAN I THOUGHT!", where The Editor plays a Sans fight on Scratch that Robo-Weapon had corrupted.
In his Undertale battle, Robo-Weapon appears as an anthropomorphic dragon with a bright yellow head and red body. On his chest, there is his signature logo, which is actually UXW's logo crossed out. His hand claws are red that fade into black, with his toe claws being pure black. He can sometimes change his torso's color to be a dark yellow, with his arms turning from a faint yellow into a shade of red. (However, this has been retconned as of the R-W Fight: HD version where the yellow torso is gone.) He also sports a red tail with a triangular point. His can also be seen with wings tucked away behind his back, being the same color as his head. When he extends his wings, they appear to be a darker shade of red on the main structure and are a dark yellow on the flaps inside. When angry, his eyes can change from empty with white pupils to appear similar to Sans's magic eye, but with a red and blue (now yellow) color scheme instead of cyan/light blue and yellow, as well as being circular instead of the traditional eye shape.
In FNaW 1, Robo-Weapon retains features such as the red spikes, green horns, and large wings. However, his body is completely yellow and lacks his logo on his chest. He also appears taller and can make his eyes glow yellow in complete darkness while playing a tune before killing his target. It should be noted that his appearance changes with every FNaW game.
Since his battle is a remix of Sans's battle, Robo-Weapon possesses most of the same powers that Sans has. He can control gravity, summon a barrage of bones, dodge attacks with perfect accuracy (unless if caught off-guard), and has the power to summon his own Gaster Blasters at will. However, he has his own unique powers, such as the ability to corrupt other projects, break a game function, change colors (okay, maybe that's not super impressive), and launch multiple attacks at once without error. His feet in the Scratch fight can heal the player, but if their HP goes over 1000, then their SOUL will explode, causing a game over. He also has the ability to jump through multiple dimensions and near-immortality, as killing him in the project results in his "Monster Attack," as seen in the project's code. He is said to have other powers beyond what the audience sees, as The Editor has confirmed that Robo-Weapon has existed before coming to Scratch. His other powers include:
time travel
teleportation
self-repair (literally)
supersonic speed
attacking the source code of a game while he's in it
interacting with the 4th Wall
capturing people in his stomach and killing them of blood loss & extreme torture
attacking one's SOUL directly
having the skills to engineer otherworldly machines and creating a clone army of himself
tampering with player control in order to achieve gaming immortality
flight
advanced data gathering
changing appearance (FNaW: EnEd)
Robo-Weapon hasn't given the audience any clear evidence of where he came from, but a comment made by The Editor states that he was created to kill UXW. However, we are given clear evidence on his backstory thanks to the Five Nights at Weapon's games.
In FNaW: EnEd, it is revealed that this Robo-Weapon was built in the 1980s, most likely before 1984 as that is the year the Dragon Diner opened to the public. Once Dragon Diner shut down, his company was bought by Computertainment, a tech company that made the new location in FNaW 2, which takes place 10 years after FNaW 1.
He is UXW's main enemy and rival. He is also the reason Dino-Weapon exists in the first place and allowed the channel to post content with him, including the Scratch projects and any hints as to where he came from. His only purpose in life (according to him) is to "eliminate the threat that UXW poses to humanity by all means necessary."

He had 3 songs made in 2022 alone, making him one of the more musical characters in the show.
Those songs are Robolovania, Entrance to Hell, and No More Light.
His Scratch game, Five Nights at Weapon's, recieved lots of updates in October 2022, with Dino-Weapon making videos on most of the alphas as they released.
He has a robotic voice, unlike Dino-Weapon.
Despite being made to resemble UXW, he has red spikes and green horns, as opposed to UXW's blue spikes and red horns.
Robo-Weapon can store up to 25 petabytes of storage in his internal memory without an external hard drive.
That is about 10 times the amount of information the human brain can normally hold.
In FNaW: EnEd, he does have some design inconsistency concerning horn size, the presence of his wings, and other small details like if his endoskeleton shows in his joints.
Robo-Weapon has many retractable parts, including thumbs, fifth-digit claws, and wings.
