Janet van Dyne AKA The Wasp, once the wife of Hank Pym, made her MCU debut in a flashback sequence alongside Pym during his time as the original Ant-Man.
She was lost when she pushed her powered suit too far and shrunk down to sub-atomic size in order to pass through metal and save Pym.
How does this compare to her written/drawn history? Was this event created solely for the MCU, or does it have a basis in any comic stories?
Furthermore, if it does, do those stories show her
returning after being lost?
