Ben 10 was a really great show that wasn’t afraid to have dark moments. That made the show 10x better in my opinion!

"Ben, you promised we'd try it my way first."
"Yeah. I lied." *proceeds to almost murder Kevin*

19:39 one of my favourite moments in the whole franchise. Chills everytime

[mlggamer]

Ben thinking Gwen died was very dark. Him saying "it should have been me" repeatedly definitely shook me at the time watching

[bob]

Darkest part for me is when Ben didn’t hold back anymore and wanted to kill people especially Kevin. That was super dark

[johny]

Ben 10 is still one of the best fucking shows ever made, Ben turning into Ghostfreak and scaring Zombozo to stop him and wave the day was so badass and scary from their perspective, especially considering Ben didn’t even have full control over Ghostfreak and he even freaked himself out, then him escaping the Omnitrix because he was actually trapped inside was such an awesome twist even as a kid, so cool man! 😄

[Unblasphemy]

Damn, today's kids will never understand how good shows were back in the 2000s...sadly.

The episode where GhostFreak went all rogue scared the living shit outta me

[LeetuPrimus]

I think the darkest moment for me was when Ben was legitimately ready to kill Kevin after he attacked his friends and Gwen. Really shows just how serious Ben can be when you hurt those closest to him.

Ben: I promise that you'll regret it for the rest of your very short lives

The moment Ben said this, I can imagine him nearly reaching his breaking point

It scared me the first time I watched that episode, I'd probably get the hell out of there and not experience what it's like to be beaten by any of Ben's aliens/various transformations and their Ultimate Forms

[thedandymancometh]

I'm surprised they didn't mention the 'Camp Fear' episode. Its heavily implied that literally 90% of the campers were eaten/digested alive by a massive sentient underground fungalspore. They only save 3 kids in that episode.

I grew up with Ben 10 and can I just say I had no idea that I wanted this video but am so glad it exists. It is so great to revile childhood memories. Love your work 😁😁

[Chikadulce]

I will never forget that two-parter where Ben almost killed Kevin in Ultimate Alien. My poor little heart couldn't take it.

Ghost freak opening his skin to scare zomboso was freaky as hell but still pretty funny a little

[carlossoto]

You know what’s the scariest thing about Ghostfreak? His true name is not revealed or spoken outside of references. The name Zs’Skayr definitely sounds sinister, but neither he nor the characters mention it, even WatchMojo here doesn’t make note of it.

[shelbybayer]

Ghostfreak's real name


Zskayr, was one of the BEST villains

[LeonardoKlotz]

This is what I love about this franchise

[Osama_Rashid]

The darkest moment was when Wildmutt talked in the beginning of "Ghostfreaked Out".

[DVZZZZ]

I think the moment Gwen “dies” and Ben shouts “i don’t care” is one of the best moments and every time I watch give me goosebumps
