Kaylee & Iron Man/Tony Stark
The adorable Kaylee from Firefly is an incredibly gifted mechanic who pinpointed what was wrong with an engine while she was, um, having intimate relations next to it. Tony Stark is a genius inventor who made his first Iron Man suit in a cave. They could bond over their shared love of tinkering with gadgets, and Kaylee could make a frilly pink Iron Woman suit so she could fly around with Tony. Twue wuv!
