What fruits in One Piece are strong in animation, but useless in reality?

Some fruits are so tough that they can crush a group of people even if they don't work hard. Although some fruits are not strong, people who use them can still rank among the strong as long as they work hard. The following devil fruit is very strong in animation, but it is almost useless in reality. Let's have a look.

First of all, the first one: the shadow fruit. As the saying goes, after the founding of the People's Republic of China, you are not allowed to become refined. Shadow fruit is quite powerful in animation. You can use other people's shadows as zombie legions. Moreover, those who have the ability of shadow fruit can swallow the shadow for their own use and strengthen their own strength. The person who owns this fruit in the animation is already Qiwuhai. But in reality, the shadow fruit feels useless, and goblins can't practice it at ordinary times, so you can't build a zombie army. Since it's useless, few people may want it if you eat or not.

Secondly, the secret fruit is also a very strong fruit, which can devour everything, invalidate the ability of other demon fruits and take away the demon fruit ability of others, which can be said to be quite strong. The person who owns this fruit has now become the Four Emperors, standing at the peak of pirates. But if you put this fruit into reality, it feels useless, but it can be used to treat garbage and swallow it. In addition, there is no other use.

The fruit range of the earthquake is quite large, which can trigger a tsunami, so strong that the person who owns this fruit is named the strongest. So what's the use of this fruit if it appears in real life? This demon fruit, which can cause extensive damage, is quite dangerous. Generally speaking, it is impossible for people to eat. If you eat it, you may be arrested. After all, eating it is like an unstable bomb. It is dangerous to destroy the city carelessly. So it's basically useless. These three fruits are of little or no use in real life.
