What about something like this? (Now keep in mind, it's from the One Piece universe in my head, so I'm not gonna bother changing it from the bio I already have typed down)

Powers: The Aura-Aura Fruit: This Paramecia-Type Devil Fruit allows Lauren to “read” the natural invisible energy waves everything gives off to a much, much, much greater extent than normally possible by those born with the ability, as well as the ability to manipulate this energy, which is normally impossible to do beyond a slight “twang”. These Auras manifest as colored, translucent, slightly larger images of objects or people. They can be as intangible as mist (an Aura) or as hard as steel (a Hard-Light Construct). While normally invisible to all but the most spiritual and impossible to detect by all but those truly in tune with themselves and their surroundings, when Lauren uses her ability, the Auras and HLCs are visible to all in the area. Lauren often uses her ability to augment her skills as a doctor. By viewing someone’s Aura she can assess the damage immediately and manipulate the Aura to allow faster healing. How fast depends on the persons will to live though. In combat she can read an opponent’s rhythm and predict their next attack from their Aura. It’s only 80% accurate though. She can also form HLCs of herself to strike an enemy from a distance, surround her arms, legs, or wooden sword to increase their power, surround her body as a shield, or create secondary and tertiary strikes following her own primary attack to enhance the force. Later she learns how to alter the shape and size of these HLCs, allowing her to give a dull object an impossibly sharp edge and even create HLCs from nothing, as they originally couldn’t move farther than two feet from the object they are shaped like. She also learns how to channel her blood-thirsty persona, Laura, into an HLC, giving Lauren an excellent combat partner, since they are the same mind they co-ordinate perfectly. The weakness of this fruit is that she can’t “see” Auras with her physical eyes, but with her mind’s eye, and as a result can be very clumsy in combat if she isn’t paying attention. Also, HLCs only stick around as long as Lauren is focusing on them. The more she uses the more fragile they are (One is hard as steel, two are hard as stone, three are hard as a very tough human, four are fragile as an untrained human, five are fragile as a human baby, six are fragile as a leaf, and seven are as fragile as wet paper), so she can only uses three HLCs at once, except during her Ultimate attack, Septum Star-Crosser, which uses her maximum HLCs (7) at once, and since she is only concentrating on the HLCs, the target, and herself, the toughness raised from wet paper to diamond. She eventually gets rid of these weaknesses and raises her maximum number of HLCs to 20 in combat, all hard as steel and 100, all harder than Diamond, during her new Supreme attack, the Centurion Quantum Splitter, leaving her only flaw her split persona, which has a mind of her own and if she isn’t in the mood or is forbidden from spilling blood or killing, might not help even if channeled into an HLC.

It's just an idea... I have plenty more. Take it with a grain of salt.
