Web-Shooters

"You know what I think is really cool? This webbing. Tensile strength is off the charts. Who manufactured that?" "I did."

- Tony Stark and Peter Parker

The Web-Shooters are a pair of wrist-mounted mechanical devices developed and used by Spider-Man to project synthetic webbing.

Creation and Use
"Is this stuff coming out of you?"

- Sam Wilson

The Web-Shooters and Web Formula were designed and built by Peter Parker himself using homemade materials and chemicals found in typical high school level chemistry classes. shortly after he gained his powers. Parker then started using them to fight crime in New York City. When Tony Stark met Parker to recruit him for the Clash of the Avengers, the web-shooters were the only part of Peter's original costume which Tony Stark didn't mock. When Stark mentioned that he might tell May Parker about Peter's double life, Peter used the web-shooter to web Stark's hand to the door handle before awkwardly helping him remove the webbing. After obtaining the Spider-Man Suit from Tony Peter replaced his old Web-Shooters with the more advance ones included in the suit, but still kept the older ones which he used again after Tony confiscated the suit.

Upgrade
"Mr. Stark really overdid it."

- Spider-Man

The Web-Shooters were upgraded by Tony Stark after Peter Parker joined him against Captain America. A holographic "Spider-Signal" was added to the shooters along with communication options. Peter used them in the Clash of the Avengers, notably using them to traverse the battlefield and snatch away Captain America's Shield. He then employed them against Falcon and the Winter Soldier, webbing them to the floor of the airport terminal. As he duelled with the Captain himself, he used the web-shooters to keep him off balance until Captain America broke out of the webbing. When Ant-Man used the Pym Particles to become a goliath, Parker used the web-shooters to save War Machine from crashing into a fuel tank. He then used them to tangle Ant-Man's legs, allowing Iron Man and War Machine to knock down him down.

First Web-Shooters

 * Regular Web-Shooting: The web-shooters are capable of shooting thin strands of extremely durable and elastic web-like substance. The high tensile strength of the synthetic webbing is sufficient to support the weight of large vehicles such as buses and trucks. Spider-Man is able to use the web-shooters offensively by "webbing" his opponents, and can also use them for transport by swinging on web-lines. The web-fluid impressed Tony Stark who exclaimed the tensile strength was "off the charts".

Second Web-Shooters

 * Regular Web-Shooting: The web-shooters are capable of shooting thin strands of extremely durable and elastic web-like substance much like the previous Web-Shooters.


 * Spider-Tracers: This version of the web-shooters demonstrates the ability to launch small GPS trackers, which Peter can track via his suit's systems.

Trivia

 * This version of Peter Parker has web cartridges attached to the waistline of his suit, allowing him to easily refill his web-shooters whenever he runs out.
 * According to Peter Parker the web fluid lasts about 2 hours before it dissolves. In the comics, his web fluid lasts for about 1 hour before it dissolves.
 * The web grenade's ability where Spider-Man fires ordinary webbing on a target, before it reacts and quickly ensnares the target in a web-net is a similar concept to the impact webbing which was first used by his clone Ben Reilly aka the Scarlet Spider.
 * The Web-Shooters as seen in Spider-Man: Homecoming borrow the concept from the most recent Amazing Spider-Man comics from the All-New All-Different Marvel event of being equipped with different settings utilized by vocal commands.
