Your first bit of advice: don’t.

Seriously, you are way better than that. As someone who’s been writing for a decade and drawing even longer, you will more often than not find yourself regretting every poorly written Mary Sue you uploaded when you were young.

A character in a story isn’t made to be fawned over, I think, in a way that detracts from the story. Especially not a serial killer who got mad their boyfriend ate their favorite cereal or something.

Your best bet is to find out why they are interesting and keep it relegated to a backstory that melds with the universe you’re creating. Give them purpose. Give us a reason to like them. Not just “oh im crazy because my mom stabbed me, then I killed her now Im Mary the Killer”. All that tells me is you’re vicariously living out a power fantasy through a character thats (most likely) hastily been made up for that purpose.

If you absolutely MUST have them be an over-powered character, at least keep them in the background as a side character so their intrigue stays intact. Over using a shtick is bound to make it become stale.

Also, having supernatural powers or a knife + several mutilations doesn’t make them cool, edgy, witty or desirable. Have the character maintain those same struggles of being human. Have them be sad, angry, confused and yes, even a bad role to look up to. Make a character you’d hate to meet in real life. They can be awkward, rude, perhaps shy. And stick true to their personality until something event-changing happens to them.

In a word, treat your character like you would a child. Help them develop fully and let them go when the time comes. A character is only as good as the events with which they interact and are affected by.
