How to write overpowered characters

Flaws

Give them flaws and challenges that they can't just power through. This humanizes them.

EXAMPLE

Despite his ability to control time, Jason struggles with social interactions and can't fix his broken relationships.

Limit their power in specific, unique ways while still keeping them powerful.

EXAMPLE

Every time Ella teleports, she loses a day of her memory.

Give them relatable desires.

EXAMPLE

Clark, able to lift mountains, yearns for a simple life with a family that understands him.

Add challenges that focus on their weaknesses.

EXAMPLE

To save a planet, Mark must solve an ancient alien puzzle. His incredible strength is useless here.

Show how others react to them and how it affects the character.

EXAMPLE

Nora's town fears her. Nora loses all the friends she once had because of this.

Give them a goal or passion unrelated to their powers.

EXAMPLE

Despite being the strongest being in the galaxy, Thanos loves farming.

Give them friends and connections that provide something their powers can't.

EXAMPLE

Alex, nearly invincible, is emotionally grounded by his childhood friend, who isn't afraid to call him out.

Their backstory should explain their use of power.

EXAMPLE

Lena's control over fire is tied to the night she couldn't save her family from a blaze.

Add a critical vulnerability.

EXAMPLE

Gregor's invincibility doesn't protect him against magical curses that attack his mind.

Let them grow throughout the story -- especially in how they understand and use their power.

EXAMPLE

Initially using her power for revenge, Jasmine learns to use it for healing.
