Devil Fruit

Paramecia
Effect

These alter the user's body in some way. Strengths

Grants the user the ability to do a trait that can be classified only as 'superhuman'.

Weakness

The Paramecia type is also the group that contains the powers or special traits that are considered 'useless' to the user, granting little or no real advantage what so ever. Paramecia types are also the easiest to fight against because while the strengths of their powers give them an advantage, they also make them easy to predict and often their abilities are displayed to their fullest within a very short period of time.

Other information 

Paramecias are the most common of the Devil Fruits types. Paramecia fruits can be divided into several subcategories, as it is impossible to generalize the powers. For instance, Luffy's Gomu Gomu no Mi is always active, meaning that he's a rubber human at all times. Other users, like Miss Valentine or Miss Doublefinger must mentally activate the changes in their bodies, while again others like Foxy and Mr. 5 can't change their bodies at all. They however all seem to come in two basic types. Whatever powers a paramecia fruit gives, it is based on the concept of either a characteristic like slipperiness or slowness, or an object like a bomb or a door.

Zoan
Effect

Allows the user to transform into a animal. This fruit provides three forms: the user's natural form, a full animal form (where the animal's size is often greatly exaggerated), and a hybrid form, combining both original and animal form (usually in a bizarre way).

Strength

Mainly improves physical abilities and allows the user to use his or her 3 forms to adapt to a situation during a fight to find the form that gives the biggest advantage. In their hybrid form Zoan users experience enhanced senses as this form uses a combination of both animals abilities. This fruit type is most useful when applied to objects such as guns or swords, giving a otherwise inanimate object life and increasing its value to the owner of the item.

Weakness

They are limited to the capabilities of the animal they are able to transform into. The Zoan type Devil Fruit is also wasted if eaten by the creature that is already, for example the human human fruit is wasted if a human eats it. However, in the case of the Human Human fruit (and most likely all cases with the Zoan Devil Fruit types) if a human ate it they would become enlightened.

Other information

While most Zoan users can only use the three forms, the Straw Hat Pirate's doctor Tony Tony Chopper can utilize more forms for a given amount of time with the aid of the "Rumble Ball", which he developed. It was stated by Chopper that carnivorous Zoans are considerably more bloodthirsty than other Zoans. A majority of the Zoan Devil fruits also come in different "models" that result in variations of the animal. For example, the Inu Inu (Dog) Fruit has a Jackal model, a Dachshund model, and a Wolf model, the Ushi Ushi (Cow) Fruit has a Bison model and a Giraffe model, and the Neko Neko (Cat) fruit has a Leopard model.

Logia
Effect

With these fruits, the user may actually become a natural element. They are neither totally human nor element in their default state. Logia users can turn completely into their element if they want to. This is often used for crossing great distances fast, or avoiding blows should their weakness be discovered.

Strength

The most powerful of the three groups. Even in their default states, Logia users are near invincible, taking no damage from physical attacks. For example, a blow can pass right through the user, while he maintains the rest of his body, and even can hold onto objects at the same time. If the user trains their new powers, the user can manipulate anything related to their element. Logia users can tap unlimited amounts of their elements from their own bodies, and the "extracted" element be manipulated however the user wants.

Weakness

The main method of causing harm to a Logia user (aside from exploiting the effects of the sea and seastone) are natural weaknesses which, when exploited, can ultimately lower a Logia users power. The only other time a physical blow may hurt the user is when he or she is caught off guard, as this gives the user no time to react to the attack. However the powers of a Logia can be trained to counter this problem, an example being Sir Crocodile's, who honed his abilities to the point of being able to turn on his powers as a reflex to a blow.

Other information

Logia is the rarest of the three groups of Devil Fruit. Logia users cannot control already physically existing forms of their element like a ice using Logia cannot control water. But they may use their surroundings to generate it. These Devil Fruits are also not limited to the classical elements: fire, water, earth, air and aether but includes physical states like smoke and sand.
