Story: all the time people have known about devil fruits and that there are three types:
a) Zoan fruits:
b) Paramecia fruits:
c) Logia fruits:
In this story world, there's two types of powerful fruits, devil fruits and angel fruits. Each type having their limitations...
Angel fruits:
Strengths
- Angel fruit users are not weak to sea water and sea prism stone.
- All angel fruits are a mix of Zoan, Paramecia and Logia types. Users can manifest a pair of angel wings to fly and create as many Halos' as they want of varying sizes, density, sharpness, thinness and strength degrees as the (mythical) zoan aspect of the fruit, they can generate & manipulate their element/power(s) like paramecia devil fruit users and they can change their bodies to become like their power(s) similar to logia devil fruit users. As part of the zoan aspect of the fruit, when they manifest their wings, their halo, hair and eye color change to the color of their element/power and wings, they grow a foot taller in height and their hair grows too. These changes revert back when user makes wings disappear.
- All angel fruit users have complete control over their element/power(s) when their fruits' awakened. Closest example would be like the benders of Avatar world (water benders can draw water from their surroundings, plants etc. bend water, ice, snow, mist, blood, swamps, mud, etc. things with water. earth benders can bend swamps, mud, metals, earth, lava, sand etc. things with earth in them. etc etc. etc.).
- Angel fruit users are immune to their power(s) and sub elements made from them. E.g. a fire angel fruit user is not going to be hurt by the phoenix devil fruit, or the fire fire fruit or the magma and smoke fruits and others like it etc. At best, they'll just feel the hot rocks from the lava attacks thrown at them.
- Like dragon slayers, they can get stronger from consuming their element/power(s) thrown at them by others. A water angel fruit user can get stronger by consuming ice, mist, blood (please don't), any water from any source, whether devil fruit or not.
- When created, the halos hover behind and around the user similar to guodoudama from Naruto. The Halos' can be telepathically/telekinetically controlled by the user to do lots of stuff. Their size, weight, length, edge, sharpness etc. can be manipulated. They can be used as a platform to carry people or even to stand on for flying. Can be used like the destructo disks from DBZ. User can channel his element/power(s) through them and release from them (similar to the Last movie where Toneri Otsutsuki, made a sword of light that cut the moon in half with the goudoudama, made a huge tornado that blew away everyone etc.)...
- The water angel fruit user can breathe in any water body and even stay for as long as he wants.
- All angel fruit users will unlock all three haki immediately after having consumed their fruit. Their haki color will be affected by their element/power(s). Aqua light blue for water, red-orange color haki for fire, dark brown for earth, white for wind, green for lightning, yellow for light, black for dark.
Weaknesses:
- Compared to the number of devil fruits, the angel fruits are too few so they're so rare to find.
- There's no variety with angel fruits like what devil fruits have. Angel fruits only come in elements and there's a few elements (fire, water, earth, wind, lightning, light, dark) so there's only seven angel fruits while there're countless devil fruits with abilities so random they are both worse and better than angel fruits (souls, sound, tremors, strings, rubber, poison etc. to name a few).
- They follow Naruto element rules in terms of strengths and weaknesses over each other.
Fire overcomes Wind. Wind overcomes Lightning. Lightning overcomes Water. Water overcomes Earth. Earth overcomes Fire.
Though if a person overpowers their attack(s), they could beat the stronger element. Like if they decide to overpower their wind attack that it just blows away the opposing fire attack instead of strengthening it.
- The angel fruits don't look any different from the devil fruits and there're only seven of them so it is by complete luck that the devil fruit you pick ends up being an angel fruit. 99% of people looking for angel fruits don't find them or end up drowning in the sea because they're testing out whether they got the fruit they wanted (idiots, am I right?).
Story: One day, a person (MC gets reincarnated in an AU or just a resident of an AU One Piece world) finds an angel 😇 fruit next to him when he awakens in his new life of One Piece or looks around (up to you how he/she finds the angel fruit).
