- Customized Helmet:
- Hearing Acuity Device: The audio in the helmet is keyed to hone in on Chameleon's specific heartbeat in order to easily detect him in disguise. Peter claims that this feature is based on Daredevil's special hearing abilities.
- Comm-Link: A special comm-link built in to the helmet that allows Spider-Man to communicate with his fellow Avengers as well as others.
- Octo-Bot Helmet: Used by Doctor Octopus when he attempted to control the city of New York and to manage his automatized Octo-Bots. Spider-Man previously used this helmet during the Spider-Island infestation. He later tries to use it to stop Octavius but fails.
- Enhanced Lenses:
- Holographic Visor: Designed to see through Mysterio`s holograms and illusions.
- "Pink Hippo" App: After spraying Sandman with a radioactive solution, Spider-Man turns his lenses on, revealing a special sand grain in Marko's body which acts as a "queen bee", telling the other grains what to do. After connecting it to his suit, he uses a smartphone to send it special orders, changing Marko's form against his will.
- Electro-Proof: The suit is capable of repelling Electro and also changing him from his electrical state back to his human state.
- Built-in Web-Shooters: The web-shooters have been heavily modified into gauntlets, which Spider-Man uses to fire larger amounts of webbing than his normal ones.
- Flight: This suit also comes with jet boosters, allowing Spider-Man to fly.
- Enhanced Durability: Spider-Man has built this suit to be durable enough to withstand the Rhino's brute force. In addition, it has also been shown to withstand a serious blow from even Thor. However, the suit has been slightly damaged by both opponents.
