Hypnotia from the 1994 Iron Man cartoon
You might say it was the shows fault, you may think that she's just a rip-off of an X-Men character called Vertigo, but I believe that she just never cought on because they didn't care about her. But if Firestar and X-23 can make it into the comics, why can't she, just give her a good origin story, and introduce her during something big in Iron Man's life.
Always wondered why she never pulled a Harley Quinn/Renee Montoya/Mercy Graves/Livewire and be expanded upon in the comics.
I take it you like Hypnotia.
Nice character. I remember her from that show. One of the few characters I liked. I wish she was cannon for Marvel.
