I dont know if Maxima was a direct inspiration but I wouldn't be surprised at all if it were true. Their MO's and visuals were awfully similar.
It was always a icky situation, with an older woman obviously manipulating a hormonal teenager. But she was a villain, it wasn't supposed to have a nice, clean dynamic.
Tana Moon is what always got me. Way back in the 90's I was closer to Kon's age than Knockout or Tana so I wasn't very put-off by the idea of someone about my age hooking up with an older woman ("older" being 25). But it always struck me as odd. And now I just find it weird. Like, Knockout I get; she was a villain playing an idiot kid. Tana? What kind of life did you lead, Ms. Moon, where a 15 year old seems appealing to you when you're in your 20's?
