Tinkerer

Spider-Man really requires a physical threat, so the last thing you ever want to see him go up against in a movie is a frail old man who comes up with a bunch of zany inventions – that’s exactly what the Tinkerer is.
His name is Phineas Mason and he’s an engineering genius whose intellect is such that it is bordering on superhuman. However, he has literally no superhuman physical attributes to speak of and is, in fact, far weaker than the average grown man.
Although he has created the gadgets for a number of Spider-Man’s villains (Rocket Racer, Mysterio, Scorpion etc) and sometimes employs thugs to do his dirty work, he generally works alone creating silly toy-like machines to carry out crimes (which usually involve using bugs to record politicians and blackmailing them) – which is what regularly brings him to the attention of the Webbed Wonder.
Unfortunately, including the Tinkerer in a movie would result in a distinct lack of action scenes – and that’s just not good enough for a Spidey offering.
