Starting off with the most actually normal one, Broly being scared of Gogeta.

Goku and Gohan are terrified of Chi-Chi's rage. That is perfectly fucking OK.

Chi-Chi scared of losing Gohan and Goten. Piccolo is also scared of losing Gohan.

Goku scared of needles. Pretty sure there's people at peak human physique on steroids that hate needles.

Vegeta's fear of Beerus. Pretty obvious that it's respect now, but hey, you can't get rid of this one!

Beerus pisses and shits his pants whenever Zeno shows up. Boom.

Tien scared of losing Chiaotzu. I mean, you already lost him fighting Nappa.

Krillin was scared of dying single. To be very honest, I would not fucking blame him.

Super Buu is scared when he has to solo Gohan. Why? Buu can absorb everyone! He even absorbed Vegito!

Krillin scared of every villain he meets. Sure, he already died twice, but still? Holy shit.

Gohan scared of losing his friends and family. Gohan, you have an extremely OP dad and you're also super OP.

Yamcha was afraid of women in the first few chapters. This is plain WTF sorta shit.

Cell scared of Super Saiyan 2 Gohan. He was just an angry kid at the time. It would've been better if Cell was cocky.

Vegeta scared of literal worms. I have one question. What the actual motherfucking fuck is this bullshit?

16 afraid of losing Earth. Mate, you've already lost your life and probably diminished Cell's sanity.

Evil Buu scared of death. What the fuck? That's- I- what the fuck?!

And that is all so far.
