Web-Shooters are Spider-Man's basic weapon. They were created from Peter Parker's incredible intellect in order to further advance his spider-like skills. Spider-Man uses these shooters for various purposes, such as deactivating multiple devices, immobilizing opposing enemies, and even traveling through New York by swinging from building to building.
The devices remained the same after it was upgraded by Tony Stark. When Peter was given his new web-shooters, they were modified from his homemade web-shooters into having numerous web combinations such as rapid fire web, ricochet web, web grenade, splitter web, taser web, and GPS tracers. It can also emit a holographic projection, that reminisces the Spider-Man mask.
