25 Best Cartoon Network Characters Ranked (Full List + Why They Matter)

If you grew up watching Cartoon Network, you already have opinions.

Strong ones.

I rewatched episodes from the 90s through the 2010s before writing this. Not just clips. Full arcs. I paid attention to character growth, voice acting, influence, and how well each one holds up now.

Some aged better than others.

This isn’t nostalgia alone. It’s impact, depth, and staying power.

Here are the 25 best Cartoon Network characters, ranked with context, strengths, and honest critique.

25. Dee Dee — Dexter’s Laboratory

Dee Dee is chaos in human form.

She’s loud, clueless, and constantly destroying Dexter’s inventions. But here’s the thing — she isn’t malicious. She’s just… Dee Dee.

Her unpredictability drove the show’s energy.

Without her, Dexter’s world feels flat.

24. Muriel Bagge — Courage the Cowardly Dog

Muriel represents warmth in a horror setting.

She’s gentle, calm, and unaware of the madness around her. That contrast works beautifully.

Courage fights monsters for her. That emotional anchor makes the show hit harder than people remember.

23. Mandy — The Grim Adventures of Billy & Mandy

Mandy never smiles.

That’s her strength.

She dominates the Grim Reaper through sheer willpower. Her deadpan tone never wavers.

I respect how fearless she is. She’s ruthless, but never loud about it.

22. Ed — Ed, Edd n Eddy

Ed is pure absurdity.

He’s physically strong, mentally unpredictable, and oddly wholesome. His randomness fuels half the show’s best moments.

Some jokes don’t age well.

But Ed’s energy still works.

21. Samurai Jack — Samurai Jack

Minimal dialogue. Maximum presence.

Jack carries weight in silence. His restraint makes him compelling.

The visual storytelling in his series elevated animation standards.

Few protagonists feel this disciplined.

20. Bubbles — The Powerpuff Girls

Don’t underestimate Bubbles.

She looks soft. She isn’t weak.

Her sweetness hides surprising strength. Episodes where she snaps reveal depth beyond the cute exterior.

That duality keeps her interesting.

19. Billy — The Grim Adventures of Billy & Mandy

Billy thrives on stupidity.

But his absurd optimism creates chaos that works.

He’s annoying by design.

And somehow, that’s the joke.

18. Gwen Tennyson — Ben 10

Gwen evolves.

She starts grounded and grows into a powerful force. Her arc feels earned.

She balances intelligence with strength. That combination made her more than a sidekick.

I always appreciated that shift.

17. Mojo Jojo — The Powerpuff Girls

Mojo talks. A lot.

But his exaggerated monologues are part of the charm.

He’s theatrical, dramatic, and weirdly lovable for a villain.

His voice acting carries him high on this list.

16. Courage — Courage the Cowardly Dog

Courage is terrified constantly.

Yet he acts anyway.

That contrast makes him heroic. He doesn’t fight because he’s fearless. He fights because he cares.

That theme still resonates.

15. Blossom — The Powerpuff Girls

Blossom leads.

She thinks strategically and carries responsibility seriously.

Sometimes she feels overly perfect. But leadership suits her.

She anchors the trio effectively.

14. Finn — Adventure Time

Finn begins simple.

Then the show grows darker, and so does he.

His emotional maturity arc stands out. He struggles. He learns. He changes.

Few Cartoon Network characters show that level of growth.

13. Dexter — Dexter’s Laboratory

Dexter represents ego mixed with genius.

His arrogance often sabotages him.

That flaw keeps him funny.

His accent, his intensity, his constant failures — they built an era.

12. Raven — Teen Titans

Raven carries emotional depth.

Her internal struggle with darkness gives the show weight.

She’s quiet, sarcastic, and layered.

The Trigon arc alone earns her a high ranking.

11. Eddy — Ed, Edd n Eddy

Eddy drives the scams.

His ambition fuels each episode.

He’s insecure underneath the bravado.

That insecurity gives him dimension.

10. Beast Boy — Teen Titans

Beast Boy balances humor and pain.

He jokes constantly. But his Terra storyline hits emotionally.

His shape-shifting ability adds visual variety too.

He’s more layered than people remember.

9. Jake the Dog — Adventure Time

Jake feels effortless.

Laid-back wisdom wrapped in stretchy chaos.

His philosophical one-liners land quietly.

He might be the emotional backbone of the series.

8. Robin — Teen Titans

Robin carries pressure.

He leads without powers.

His obsession with control and Slade rivalry gave the show stakes.

He’s disciplined, flawed, and intense.

7. Buttercup — The Powerpuff Girls

Buttercup brings aggression.

She’s blunt. Impatient. Fierce.

Her tomboy energy balances the team.

She doesn’t soften herself for approval.

That confidence matters.

6. Aku — Samurai Jack

Aku is theatrical evil done right.

His shape-shifting form keeps him unpredictable.

His voice performance carries menace with humor.

A villain that patient rarely fails.

5. Ben Tennyson — Ben 10

Ben evolves from cocky kid to serious hero.

The Omnitrix concept alone made him iconic.

His growth across versions strengthened his staying power.

He carried a franchise for years.

4. Ed, Edd, and Eddy Trio — Ed, Edd n Eddy

Together, they’re stronger.

Their scam dynamic never grows old.

The friendship underneath the chaos gives heart to absurd plots.

The finale film sealed their legacy.

3. Finn & Jake Duo — Adventure Time

I’m grouping them.

Their chemistry defines modern Cartoon Network.

They mix comedy with existential storytelling effortlessly.

That balance changed animation tone in the 2010s.

2. Raven & Starfire — Teen Titans

Opposites that work.

Starfire’s warmth contrasts Raven’s restraint.

Together, they gave emotional balance to the team.

Their friendship moments remain strong even today.

1. The Powerpuff Girls — The Powerpuff Girls

It comes back to them.

Blossom, Bubbles, and Buttercup defined late 90s animation.

Strong female leads. Bold art style. Memorable villains.

They shaped an era.

And they still hold up.

How I Chose These Characters

I considered:

• Cultural impact
• Character development
• Voice performance
• Longevity
• Rewatch value

If a character only worked in one era, they dropped.

If they influenced future animation tone, they rose.

Final Thoughts

Cartoon Network shaped childhood for millions.

These characters weren’t background noise. They were personality anchors.

You probably disagree with at least three picks.

That’s normal.

But if you rewatch a few of these shows today, you’ll notice something — the writing was sharper than we gave it credit for.

And the best characters still feel alive.

That’s staying power.
