Dragonfly and Cheetah are very similar both in personality and in backstory. I can see them bonding with one another, maybe even Dragonfly becoming protective over her- purely because she's the most like him.

If you WANT we could work something out and say they were both test subjects from a different iteration of the same super soldier serum. This could lead to Dragonfly saying things along the lines of 'You smell familiar." or whatnot. Even if they've never met.
