Place of Formation
Web-Warriors were a team that consisted of Spider-Men.

Spider-Man summoned those Spider-Men via Electro-powered Siege Perilous to stop "Spider-Goblin". 
The second team was a sub-group of the New Warriors consisting of Spider-Man, Agent Venom and Iron Spider. Later Scarlet Spider aided them to stop Doctor Octopus and Arnim Zola from taking over New York City and reluctantly stayed. Spider-Man from Earth-TRN457 later rejoined the Web-Warriors after the Siege Perilous was destroyed and stranding him in Earth-12041.
