Tinkerer



Phineas Mason aka 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.
