Well I have been enjoying the My Hero fanfiction section for a couple of months now. I pretty much favorited most of the big fanfics on that page at this point. Though I notice that some possible abilities and powers haven't been used for our boy Deku quite yet so I'm putting out a list for possible power ideas for writers to use. I hope that some good writers end up picking up these powers and using them in a possible fanfic
Adaptive Muscle Memory: The user can copy any/all movements/actions after seeing it performed once, including acrobatics, martial arts, and other physical stunts. With these skills, they can become masters and incredible at what they do, by combining what several forms and movements in rhythmic motions instead of using the same thing over.
User can copy how a person aims, giving themselves incredible marksmanship; however, if they wanted to use certain weapons, they would have to watch a person fire that weapon in order to be able to copy it (such as how to fire a rifle, as opposed to how to fire a bow, or how to throw knives or darts)
This abilitiy is simple but has so much potential when it comes to someone like Izuku. Izuku could still end up with One for All and wouldn't end up overpowered. So anyone want to take a shot at it?
Psychometry: The user obtains historical memories or sensations concerning beings and objects they observe. With objects they gain the knowledge including the makers, users, and even those who have on passing used the object, and what has been done with it. With living beings or parts of the body the user learns their general life-history, but doesn't gain anything of what they were thinking or feeling.
Another one that has vast possiblities if you use it correctly. Izuku could gain some skills if he ends up collecting old weapons/objects, learn a person's history and who knows what else. Also falls under another power that could go with One for All
Plant Manipulation:User can create, shape and manipulate plants, including wood, vines, plants, moss, and parts of the plants, such as leaves, seeds, roots, fruits and flowers. The user can cause plants to grow, move/attack or even rise from the soil and "walk", mutate plants by rearranging DNA structure and revive withered or dead plants.
They can use their power for defense and support, cause flowers and other plants to bloom instantaneously, manipulate tree branches to use them as whip-like weapons, control spores and pollen, and bring plants back to life and make them sprout seeds/fruits/berries, use plant chemicals to heal people/objects or manipulate their properties for a wide range of effects.
Though less commonly activated by passive users, the ability may deal a series of offensive techniques on a target. Using the plants as weapons enables users to grasp and strike continuously with vines and roots, project thorns at a distance, and quickly regenerate the withering weapons at the user's will. They can grow vines to entangle enemies climb around a target's neck, causing choking, or strike with plants. A more subtle technique is to release damaging toxins and pheromones, affecting targets in which conditions should be treated quickly with ailments.
I'm actually surprised that no one has done this one yet. Hero name can refur to a certain tree in Legend of Zelda and he has green hair and green eyes. The possible ideas he can come up with, with this quirk are vast. This one would be one of the ones that nobody would complain that Deku didn't get All for One or that All for One works differently when Izuku uses it.
Empathy:The user can fully interpret and replicate the emotions, moods, and temperaments of others without reading apparent symptoms, allowing them to understand introverts or discover one emotion is actually hiding another. They can attack someone in a personal and emotional way since they know exactly what emotion is flowing through themselves and can use this knowledge to play against them. Some users may learn to read emotional imprints left into environment or objects.
Usually over time, an Empath's power grows to the point that they can manipulate emotions on others, and possibly use them to empower themselves. The user may learn to extend their power over/on vast number of sentient beings or reach extreme distances, even other levels of existence but this may be possible only if the user has emotional link to those they search already in effect.
Izuku is a empathic type person in the anime/magna why not take that to the next level. It's not a very offensive abilitiy...normally anyway and I would be interested to see what writers would do with it.
Were-Cat: User with this ability is a werecat (including were-jaguar) with the ability to transform into a feline or an anthropomorphic creature, gaining features of a feline such as domestic cat, tiger, lion, leopard, lynx, or any other type, including some that are purely mythical felines. Unlike werewolves, they aren't particularly connected to moon or have any weaknesses for silver or their other traditional weaknesses.
Truth be told I got this one from the Gold Digger comic sereis and thought it would be cool. Especially if you use the bit that Izuku would have a full animal form along with his hybrid form. I've seen a few good Izuku with a dragon type quirk let's add a bit more to the beast list with some kind of were cat.
Paper Manipulation:The user can create, shape and manipulate paper and/or paper-like substances, such as papyrus and parchment
Another simple power that has a lot of possiblities. Got this one from R.O.D: Read or Dream anime. Who know what Izuke can come up with and there's the fact that well Paper is readly avaliable.
Absolute Cuteness:The user possesses a level of cuteness which exceeds all others, possibly being/becoming the cutest thing. The user can use their overwhelming cuteness to control and affect others. This power can be used two ways:
The user can possess sincere adorability, an innocence whose cuteness is pure and benevolent, a user like this could possess this ability without even realizing it. Or the user could be malevolent, using their overwhelming, hypnotic cuteness as a weapon to manipulate people.
Ok I can honestly say that this one is here for the possible laughs more than anything else :D but is someone can turn this into something great then you got a mind on you.
Silence Manipulation:User can create, shape and manipulate silence, absence of noise/sound.
Pretty much a Izuku able to make a quiete zone around himself that could be used for all types of sneak attacks or stealthy movement. Heck if you want to pair him up with a certain invisible girl they would be the perfect stealth team.
Sound Absorption:The user can absorb sound waves, while removing it from the source, into their body and use it in various ways, gaining some form of advantage, either by enhancing themselves, gaining the drained power, using it as power source etc., either temporarily or permanently.
Truth be told again this one was inspired by Dazzler from the X-Men. Once again if you want a certain pairing aka Earphone Jack. Then this one would help with that.
Earth Manipulation:User can create, shape and manipulate earth and "earthen" elements including most solid objects, specifically all minerals and mineral compositions regardless of their state (mountain, boulder, sand or dust), dirt, soil, etc.
All I can say about this one is I'm a Avatar fan and love Tohp style of Earthbending. Quite the powerful quirk.
Insect Physiology:User with this ability either is or can mimic/transform into an insect, including cockroaches, beetles, earwigs, flies, mayflies, termites, mantises, sticks, etc.
This one pretty much had me thinking about the comics aka Ant Man and the Wasp. Shrink to insect size and possibly have the abilities of a certain insect. Heck you could get really creative with this one.
Well that's all for now though I have a feeling that I will end up making another list of possible powers that our boy Deku could end up having. Hopefully this helps out writers and help make more interesting stories.
