Whether it's Invader Zim's maniacal laugh or Orochimaru's spine-tingling cackle, nothing defines a character like insane laughter. Enjoy these creepy laughs from anime characters!

1. Kira from Death Note

Light Yagami's voice actor, Mamory Miyano, is a natural at creeping viewers out! His laugh when he was revealed as "Kira" truly illustrated the slow insanity that took over him in the end.

2. Stein from Soul Eater

Stein's voice actors aren't holding back with their hair-raising cackles! There are several moments throughout the long-running series that'll feature Stein’s laugh again and again.

3. Rena from When They Cry

Rena's laugh is borderline annoying, but when you consider the fact that the show is a murder mystery well... it's rather appropriate.

4. Lelouch from Code Geass

Honestly, I wouldn't mind watching Lelouch's voice actor at work in the studio. That laugh is so impressive.

5. Yuno from Mirai Nikki

Mirai Nikki is a popular anime series, and it's likely that its life-or-death survival premise hooked fans right from the start.

They don't fail to deliver in the creepy laugh department, as Yuno's laugh in this climactic scene has a childlike factor to it that makes it all the more uncomfortable.

6. Shion from When They Cry

If Rena's laugh wasn't enough to put you off from watching this, maybe Shion's blood-curdling Ahahahahas will make you think twice.

7. Orochimaru from Naruto

Mind you, we're not even talking about Orochimaru's male form. It's when he takes over a woman's body and starts laughing with her voice.

8. Alucard from Hellsing

Who doesn't love Alucard from the ever-so-popular Hellsing series?

9. Sasuke from Naruto Shippuden

It seems like Sasuke won't let Orochimaru get all the glory. He performs his own maniacal laughter in episode 214.

The only question is: Who laughs better?
