[MCU] Did Tony use any of Stane's Iron Monger designs when working on the Hulkbuster suit?
gpt
No.

Unlike in the comics, where Stane's hardware is distinct and seperate from Tony's gear (to the point of Tony once building himself a "Staneware" suit as a countermeasure in case someone finds a way to undermine his standard "Starktech" gear), in the MCU Stane isn't really contributing much to development. He's a businessman first and foremost, followed immediately by being a ham-fisted goon; his functional yet unelegant solution to the power problems with the Iron Monger was to burgle Stark's house for an arc reactor. Everything about the Iron Monger is plagiarized off Tony's "box of scraps" Afghanistan suit, with the only improvements being in the quality of resources available to build it.

There's literally nothing for Tony to learn by studying Iron Monger, except perhaps the dangers of hubris.
