Phineas Mason, also known as the Tinkerer, is an evil genius and inventor who most frequently opposes Spider-Man, but also makes gadgets, weapons, and upgrades for many various Marvel supervillains. In his first appearance, Mason, (as the Terrible Tinkerer) composed a conspiracy with Quentin Beck (later Mysterio) in which they pretended to be aliens infiltrating the worlds technology systems. After he was defeated, however, Tinkerer became a weapons dealer for many villains, using his scientific genius to build amazing creations.
The Tinkerer is the main antagonist of the 2009 video game, Marvel Ultimate Alliance 2, having assisted Lucia Von Bardas in her plans, and being the true mastermind behind the creation of the nanites that were used during the Civil War, that would eventually become a collective known as the Fold.
A much younger version of the Tinkerer appeared in Spider-Man Homecoming, as the person who creates Vulture's suit, played by Michael Chernus.
