Even if you’re not a comic book nerd, you probably know what that glowing green rock is, or at least have heard of it.
For the truly uninformed, it’s kryptonite, aka The One Thing That Can Harm Superman. It drains his powers and makes him decidedly non-super.
And it’s also incredibly necessary, because without any kind of weakness, Superman is pretty much unstoppable, which is BORING. Who wants a hero who can’t be defeated? Who always wins? Why should we care about him if there’s never any doubt he’ll succeed?
A protagonist needs some kind of weakness or flaw, like kryptonite provides for Superman.
Bonus – it also adds to the conflict.
I recently read a script where everything went perfectly fine for the protagonists. Every obstacle they encountered, they overcame with ease, then casually moved on to the next thing.
Where’s the conflict in that?
If a protagonist’s road to their goal was a long and empty straightaway of perfect asphalt, low gas prices and nothing but green lights so they get to their destination ahead of schedule, is this a story that would hold my interest? Not really.
But what if that road were nonstop twists and turns, laden with potholes, overly aggressive drivers, and a poorly timed construction project blocking 3 of 4 lanes AND the protagonist was running out of time to get somewhere they absolutely had to be? That is a story I’d want to see.
The protagonists in this script had no flaws. Everything always worked out for them – sometimes with little to no effort on their part. I told the writer they needed to do the opposite. There needed to be conflict for these characters at every turn. What was going to stop them, or at least slow ’em down?
Included in my notes – “What’s their kryptonite?”
Your hero needs to have a rough time in reaching their goal. (CONFLICT!!) Overcoming obstacles both physical and emotional is what provides the opportunity for them to learn and change. Without that, they remain stagnant and the reader/audience won’t care about them, let alone if they achieve their goal.
What’s your protagonist’s kryptonite? What’s stopping or at least hindering them from achieving their goal, and how can they overcome it? Does that help them grow and change?
Superman always finds a way to overcome his run-ins with kryptonite. Can you say the same about your protagonist?
