To my knowledge these are usually pretty temporary. Though I imagine with how often Jessie and James get zapped, theirs are a bit more severe/long lasting. They cover them up with makeup in the places where the scars would show.
Ash's go away quick. They're usually on his hands because he has, willingly given Pikachu his hand to shock in order to help him think, get an idea or wake up (this is a thing he actually does in the show LOL)
submas soul eater au! ingo and emmet are both weapons that wield eachother
extra info:
- their weapons reflect how each of them fight -> ingo hits hard and makes it count vs emmet who’s quick and agile so they balance eachothers weaknesses
- they run a train which runs outside of death city and across the country ; due to frequent attacks from kishin, they were stationed there to protect the train and it’s passengers
- of the two, emmet has the larger soul and is able to use soul perception. ingo’s soul is smaller, but he has a much stronger resistance to madness
