Worst Villain Plots from 80's/90's cartoons?

[Gray Lensman]

Any villain plot hat involves them using super-advanced technology to do something as mundane as robbing banks. They could sell the tech and make waaaaay more than robbing banks would get them and they wouldn't be wanted or get punched in the face. Hell this works for any villain wanting to use tech to hold the world for ransom. Just sell your inventions, genius!

There's an issue of Power Girl where they bring this up. It's the story arc with Vartox, where in the intro they are fighting Blue Snowman and Doctor Midnight specifically mentions her cold ray tech is worth more money than the gemstone she was trying to steal with it.
