Parodied: The heroes' plan to neutralize Melinda is to get her to change her clothes. And it works.
Zig Zagged: Melinda wears a completely black outfit, but she seems to be a nice person. Then we find out she's simply Affably Evil. Halfway through the series, she does a Heel-Face Turn and switches to brighter colours. But after a while, she decides black suited her better and starts wearing it again, even though she's turned good.
