Go ahead and try this. This is inspired by notetocharacter. Just write to your character and complained at their incompetence or be in awe of them. Or you can have your characters write to you! Try it out and post it in this sleepy community! XD
Here's my example, I'll keep it small to two characters:
Unlike your siblings, your cleverness outshines them! I mean seducing Alan to set you free from your prison and used a Yo-yo as your weapon of choice to defeat and whack your tormenter Ursula will have me laughing for a long time. I had to admit, you were meant to lighten the story's atmosphere with your comedic antics but you came out well-round because of your sincere feelings concerining Alan. Not bad for a clever Demon. X) Yo-yo's are unexpected weapons indeed besides Luan's huge Frying Pan of Doom.
It pains me to write you because you're a manifestation of my negative feelings towards life. Writing you is like writing me, I know it hurts when bullies make fun on how smart and gifted you are and then you get brutally beaten up for it. You're a nice boy but misunderstood. Don't worry, those bullies will pay and I'll make sure of that!
