Scenario: You have died and you will be transmigrated to another world, the goddess in charge you said that your cheat will be an extra organ and nothing else. What part will you choose? Things to consider: 1) only one part can be replicated however the size ,extent and placement is up to you. Ex. You can only have one extra arm ( hand and fingers included) not a pair, however you can place it anywhere such as your back, shoulder, or up your bumhole. it can be teeny sized or giant sized but take note your body will require extra nourishment for your bigger body part 2) no magical addition, your extra arms cannot throw fireballs, or your extra eye shoot out lasers 3)other body parts from other animals can be included such as a wing from an eagle, or a gill from a fish, or scales like a reptile 4)all other isekai rules apply i.e magic and cultivation can apply if in isekai setting ( ex mage staffs and dimensional seed worlds
Extra heart . Or whatever core organ it is that can store and reproduce mana in the internal body.. otherwise I might turned out like that girl in mushoku tensei where the body quickly becomes sick and dying cause of mana poisoning. Preferably made with materials from dragons or angels..
maybe a small manageable sized dinosaur tail like and ankylosaurus would the spikes/scales and knocked be included though since its just single limb
Literally anything would make you deformed and a social outcast. No body part would be worth the deformations, given the lack of a MC halo
I have not so pure mind so i would request "that" part, the harem must be pleased....... ........ you know what "part" i mean right?... ....... ....... ....... Spoiler Its obviously extra ring finger so you can put more wedding ring harem cannot complaint if there is available space
But if you are OP enough, you can just start your own tribe, provided that your extra feature is hereditary. In the first place, if you are reincarnated, you probably have the MC halo
A Vagina. So you can go F*ck yourself. Not Really. In all seriousness, I would like a sensor-membrane, so I could have heat-vision
The organ that lets spiders create their webs in my palm or a giant retractable stinger/claw in my other palm.
