What is/are your most hated Devil's Fruit powers?

The mol mol fruit.....I hated that one.

I actually like the Yami Yami no Mi. I like it because it means that when Luffy kicks his ezel there'll be an awesome battle!
oh, oops... I forgot to write what my least favourite devil fruit was. Thanks BlackPanther666 :). I guess I'd say that my least favourite devil fruit would be the Whoshu Whoshu no mi that Tsuru uses. I thought that it was really stupid... Washing people's evil off and then hanging them out to dry... It sounds like it was mostly for comic relief. What if someone evil ate that fruit and their enemies are good guys? Wouldn't help them much in the long run...

The Supa Supa no Mi (Steel Fruit) I hated. Because how can u "kill" steel? Only Zoro could slice through him but.. No one else could, beside Hawk Eyes Mihawk. That guy could defeat him.

the rust rust fruit firstly because he destroyed Zoros sword >:( & cause its just stupid "ohhhhh i rusted your sword what now?"
"wow hes so cool he rusted that sword!!!"....not really

i hate when people make animals into weapons but i also hate gura gura fruit because ITS WAY TO over powered like u can destroy the world, plus i hate the fact that whitebeard barely used its power and could have easily won the marine fight. as soon as blackbeard gets it this guy manipulates the frigen sea made me mad lol

Goro Goro no Mi

"(Mine is the Yami Yami No Mi [Darkness fruit], because it has too many different things that Teach can do, that are too damaging/powerful. I don't like that he can manipulate gravity, nullify Devil's fruit powers and become darkness, all in one. It was pretty op.)"

My thoughts exactly. It's definitely pretty op.
