Officially by normal comics history he uses mechanical web shooters of his own design. There have been instances where he had his own organic web shooters for a while and when he wore the alien symbiote it produced its own web.
Okay, so the general rule of thumb for Spider-Man is that he can’t shoot his own webs. In some stories, he can (I’ll discuss that in a moment), but more often than not, Spider-Man shoots artificial webs derived from mechanical devices on his wrists. The devices Spider-Man uses are called web shooters.
Peter had argued that a spider (even a human one) needed a web. Since the radioactive spider bite didn’t initially give him the power to spin webs, he found a way to create them artificially instead. The wrist-mounted devices fire a self-adhesive “webbing”.
His bodily functions were altered in such a way that his wrists developed their own web that he could use. Director Sam Raimi reportedly gave Tobeys Spidey organic web shooters to make him more realistic as a character. He feared that if Peter invented his own gadgets, it would make him too smart and inaccessible to the public.
When Spider-Man fires it, his web shooters eject a highly flammable chemical solvent from the vents that bursts into flames on contact with the intended target if sealed in enough liquid. Sonic disruptors are useful against symbiotes and for destroying non-solid objects.
This included reasonable strength and speed, as well as increased reflexes and the ability to climb walls, but the comic version lacked the ability to build webs, the main form of hunting most spiders, So gave Raimi his version of Spider-Man Organic Webs.
Cosmic Spider-Man is undoubtedly the most powerful variant of the character. In the Acts of Vengeance storyline, Peter absorbs a mysterious force known as the Enigma Force.
Probably. But spiders produce silk from specialized glands in their abdomen, so they will eventually produce more.
Director Jon Watts explains why the Webslinger is missing one of its signature superpowers. One of Spider-Man’s main superpowers is his spider sense. It basically gives him super reflexes and allows him to anticipate attacks and the presence of enemies.
Parker eventually developed a formula to make his own custom webbing consisting of salicylic acid, toluene, methanol, carbon tetrachloride, potassium carbonate and ethyl acetate.
Venom’s abilities are based on Spider-Man’s because the symbiote draws on its previous experiences with a human. That’s why Venom has super strength, shoots webs out of his hands and wears a giant spider emblem on his chest.
When the symbiote took over Peter, all he did was mold over the Spider-Man suit, turning him black while granting a buff to his speed and strength while he on the other hand Peter’s suit altered mood and personality.
However, the “human-spider” hybrid died and Peter was reborn with the ability to organically spin webs instead of using his web shooters, as well as the ability to communicate with him Insects.
