4. Devious
Definition

- Dishonest, yet successful in being so.
Examples

โDespite the sirens getting louder and the red and blue lights closing in, hisย expressionlessย face made it seem like the game wasnโt over just yet.โ

โIntenseโ not only shows the strength and power of your character in relation to others, but it also helps to demonstrate their devotion to their convictions as a character.

How it Adds Description
Thereโs usually going to be something about your criminal mastermind in your story that makes them a little unhinged, and โmaniacalโ is a great way to present this! It could describe an action, such as a laugh or a movement, or show the way they approach things in a far from conventional way.

โYouโll want to stay on his good side. He might seem like a nice enough guy now but he isย mercilessย if you ever cross him.โ
How it Adds Description
If your criminal mastermind is โmercilessโ, then your reader knows that anyone who ends up on the wrong side of them is likely to be in real danger.
