Phineas Mason, also known as the Tinkerer, is a former salvager turned professional criminal who used Chitauri, Dark Elf and Ultron technology salvaged by Adrian Toomes to create all new powerful weaponry. Due to the actions of Spider-Man, Tinkerer's weapons came under risk of being found, and therefore, Toomes considered shutting down their organization.
