Paramecia

Paramecia (超人系 (パラミシアけい), Paramishia-kei ) is the name given to a type of Devil Fruit. These fruits give the users a "super-human" power which can affect their body or ability to manipulate the environment.

First Appearance: Chapter 1; Episode 1

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. These can be exploited and manipulated in a variety of ways, though the extent of useful attacks or strategies can depend greatly on the user themselves. Some people may encounter inspiration for a new attack after using a particular set of attacks for years, while others will never learn how to completely harness their skills.

Weakness
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. Paramecia types 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 (as noted by Eneru).

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 (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 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, Don Achino, and Magellan). These types of Paramecia are not confused as Logia, though, since the users cannot convert themselves into their respective substance, nor do those particular substances count as actual elements.
