Spider-Man # 21 1992 NM-

Spider-Man #21, published in April 1992, is a fan-favorite issue from the "Copper Age" of comics. It is most famous for debuting the iconic "Cyborg Spider-Man" look.

The Story: "Dealing Arms"

Part of the six-issue "Revenge of the Sinister Six" arc, this story was both written and illustrated by Erik Larsen.

• The Transformation: After getting brutally beaten by the Sinister Six in the previous issue, Peter Parker is "repaired" by a scientist at Care Labs. He is fitted with a cybernetic eye-patch and a robotic arm cast to help him keep fighting despite his injuries.
• The Mission: Cyborg Spidey teams up with the heavy-hitters Deathlok and Solo. They track the Sinister Six to an alternate dimension where the villains are stealing advanced alien weaponry to conquer Earth.
• The Villain Flip: While the Sinister Six are the main threat, this issue shows Doctor Octopus solidifying his role as a cold-blooded leader, even being willing to sacrifice his own teammates to succeed.

Why Collectors Want It

• First Appearance: This is the first full appearance of the Cyborg Spider-Man design, which has since become a popular skin in video games (like Marvel's Spider-Man) and has its own action figures.
• Action-Packed Art: Erik Larsen’s hyper-detailed, energetic '90s art style is at its peak here, featuring massive explosions and tech-heavy character designs.
