Phineas Mason is an insanely brilliant inventor who works for super villains designing their weaponry and gadgets, though he has been known to undertake criminal enterprises of his own. As his alias, the Tinkerer, he runs an underground military-style engineering bay disguised as a simple radio repair shop. Several times, customers have confronted Mason by entering his shop and presenting a radio to assist in his guise, often letting out a witty quip such as, “I’ve got a radio here that just can’t carry a tune.” The original scheme of the Tinkerer involved the employment of several thugs and placing bugs in repaired radios to gain secret information on people and blackmailing them. During an escape from Spider-Man he left behind a mask resembling his own face, and took off in a very UFO-like hovercraft. Thus it was believed for a short time that the Tinkerer’s genius came from an alien culture and that Tinkerer himself was an alien.
