DF Type Paramecia (One Piece)

Paramecia (超人系（パラミシア） Chōjinkei [Paramishia], literally translated as "Superhuman System") is one of the three types of Devil Fruit. These fruits give the users a "super-human" power which can affect their body, manipulate the environment or produce some kind of substances. In general, Paramecia Devil Fruits are fruits that give their users powers other than transforming into elements like Logias, or transforming into animals like Zoans. Though they do not include powers that allow elemental or animal transformations, some of them are capable of other forms of transformations. This is the most common class of Devil Fruits. In the edited dub, this class is called Paramythia.

Strengths

The Paramecia fruits grant users an ability that can be classified only as 'Superhuman'. The Paramecia fruits also contain the greatest variation of powers evident so far in the One Piece story.
The largest advantage of this group is that even physically weak fighters can make use of this fruit class, as demonstrated by both Robin and Mr. 3. The primary focus on the fighting styles of users does not have to rely on the physical strengths or fighting skills of the individual themselves and is usually more focused on users creativity and initiative. The Paramecia group therefore can make fighters out of even weak individuals and the type of consumer likely to eat this fruit has proven to be much more diverse than other fruit classes.
Although the abilities can be exploited and manipulated in a variety of ways, the extent of useful attacks or strategies depend greatly on the users themselves. Some consumers may encounter inspiration for a new attack after using a particular set of attacks for years, while others may never learn how to completely harness their skills. One such example is Brook, who although spent 50 years harnessing his Devil Fruits abilities to keep himself alive, he never discovered the full extent until his seperation from his crewmates led him to attempt to explore his Devil Fruits full powers.

Weakness

Wapol attempted to eat Luffy,
but failed in his attempt due to Luffy's fast reflexes.

to turn his tongue into a cannon.

The Paramecia type is the only group containing powers or special traits that may be considered "useless" to the user, granting little or no real advantage whatsoever until such time that they learn how to hone their control. As personally experienced by Luffy, his powers of elasticity proved almost useless after he first (accidentally) acquired them, and it was only much later on did he realized the Fruit's utmost potential. In short, the aspect of the devil fruit being "useless" may sometimes be due to the user not being accustomed to it efficiently deploying the abilities they receive. Their abilities may also end up proving completely useless in some situations where they would normally otherwise have been quite formidable. Therefore, even the best of fighters may be strained to be able to use their abilities to the fullest.
Paramecia users are also considered the easiest to battle, since they can be predictable and often display their full abilities within a very short period of time. The results and capabilities of these fruits are therefore limited to the creativity of the user in any given scenario to overcome the limits and predictability of the fruits.

Some abilities of this type of fruit also add further implications, as in the case of Kuma and Decken; Both must keep their hands covered as their abilities are released from their hands. One might also argue that the same scenario would apply to Mr. 2 Bon Kurei - however, he is not seen to cover his hands.
Although other Devil Fruit types may also lead to the user being considered a "freak", none are more noted for this than the Paramecia group. This is due to some of the abilities granted by Paramecia fruits being considered far too strange or frightening for normal people to accept.

Other information

Paramecia are the most common type of Devil Fruit. They come in a variety of forms which can be divided into several subcategories.
With such a broad range of available powers, it is difficult to generalize the abilities offered by Paramecia fruits. However, it appears that the effects of this Devil Fruit type can be categorized into two basic groups: those which are based on a characteristic (such as elasticity or slowness) or an object (bombs, doors, etc.). Paramecia types are also distinguishable in the manner in which their powers manifest. They can either alter the user's current physical state (Luffy and Bon Kurei), directly affect their immediate environment and/or living things within proximity (Eustass Kid, Blueno or Whitebeard), or affect both of these conditions (Jewelry Bonney and Emporio Ivankov).
How to trigger the fruit’s power can also differ from user to user. For instance, Gomu Gomu no Mi and Yomi Yomi no Mi have powers that are active at all times, while others such as the Noro Noro no Mi and Hana Hana no Mi require self-activation.
There are also many types of Paramecia that could be easily mistaken as Logia, either due to the user's ability to release near-limitless amounts of a particular substance (or energy) in relation to the power their fruit gives (Mr. 3, Kalifa, Musshuru, and Magellan); or that they are able to mimic the properties of certain existing matter (Mr. 1, and Jozu). These types of Paramecia are not to be confused as Logia, though, since the users of the former category cannot convert themselves into their respective substance, nor do those particular substances count as actual elements, and neither can those from the latter sort generate the same aspect from their bodies that they are capable of transforming into.
