Phineas Mason (Earth-4026)

"You realize this is alien tech, right? I can't just whip up a bird suit in five minutes. I mean, of course I'm gonna do it because this is fucking cool, I'm just saying it'll take time. And a lot of money. But since we're such good friends, I'll let you have it at 25% off, but no discounts on upgrades."

- Tinkerer

Phineas Mason is one of the smartest people on the planet who uses his intellect to build and upgrade tech for supervillains to use.

Trivia

 * When building Vulture's suit, he saved a large portion of the Chitauri tech for future purposes. He more often than not wears one of the gloves he salvaged to protect himself.
 * During his first face to face encounter with Spider-Man, they struck a deal so that Tinkerer would repair and upgrade his fairly damaged suit in exchange for Spider-Man not turning him in. Immediately after Spider-Man left, Tinkerer packed everything and relocated. Peter felt incredibly dirty for letting him get away.
 * One of Phineas's most frequent clients is Bolivar Trask, who is using his tech for Hydra.
