gibli or soul eater or South Park or dragon dentist or hazbin

can't believe I forgot! made in the abyss depth mutation with saphira having tragedy immunity from magic would almost be too easy for an upgrade

keep eragon skill material based because the world he's from alongside lotr has a theme with mortal mentality and bending that too far too fast with something like cultivation or spamming heavily conceptual magic is going to have existential issues(dropping a moon on someone like Thanos every now and again should be fine). eragon fits the Targaryen naming sense. deep sea or deep earth treasure hunting. silmarils and eldunari. lotr build a ring workshop. d and d world when you need an easy mcguffin or story fix. HP Hermione falls for lotr because she's a fan of the books. breathing techniques because somehow people think they're more sci Fi than magic. eragon gets a rogue samurai straw hat.

you could shred into something whimsical like adventure time with the protagonists mid story under base post apocalyptic context, an Fullmetal alchemist alternate given Envy's dragon reaction to the gate of truth that can be spun any number of ways as an in between speaking of winry is close enough to classical or wholesome especially with the amount of character developmental aging used, funny enough a meaningful saphira upgrade might need to be esoteric in nature maybe a little biblical like king Arthur or Shinto because I don't know what you have in the works with that Norse Viking guy

off of the original eragon go with experienced women who for whatever reason are young physically or mentally because nasuada, saphira, and Arya fit the bill. saphira is already primed considering the bond only needing a perception shift and an upgrade maybe a downgrade. Arya taken out of algaesia and introduced to lotr lore(throw galadriel an adventurous daughter and you have the same deal). hobbits or dwarves are going to be a hassle to workout. any kind of spice the people of lotr or algaesia would consider an exotic personality probably also needs to arrive in this first world first to add context or denature to avoid awkward flashback and overly excessive bonding scenes that make for slight logic gaps in the timeline, because why would they pretend not to be involved enough to want to be creative enough with their time to handle necessary activities romantic or otherwise unless making a disfunctional break from the semi medieval relationships of lotr and inheritance

wild magic as the norm with focuses like rune, images, or words for beginners that way you never have to change the system because it fits just about anywhere they might go

forgot; quantum lock off each other transferring force to the last scale coating to be sacrificed like a st Rupert's drop that is quickly replaced by the enchantment or just have a smallish crystalline mace at the end of her tail storing and releasing that force like an ice breaker or dainty gate breaker for the wich king of angmars castle I mean helmet face

you need to wa.... run a marathon with your ninja husky on the daily bro!

maybe Sasuke inherited it from Itachi's eyes who may have inherited it from shisui because the method of incarnation may not have been mentioned. It could be something more physical like the pirates of the Caribbean pieces of eight tokens, the uchiha eyes, or Tsunade and hashiramas crystal necklace

that's called cancer. lol

different universes different logic just look how well it worked for that logic defying candy store owner from bleach. lol

the money sure if you have a hole in your pocket, the knives maybe he wants to widdle or blow off steam like with archery, but a four year old testing explosives on any available surface public or private like graffiti because they haven't been around long enough to know better? just think of all the graffiti covered restrooms or poster covered walls. why would you think this is a good idea let alone okay or vaguely helpful when they have trouble counting and ruin their future with terrible permanent injuries?

Danzo: this is why I had to kill the hatake clan head. snow is a long term conspiracy popularizing their natural hair color by adjusting the color of the snow ever so slightly every year so that people associate the hatake with the hokages. even the names are just similar enough that no one thinks it's intentional, don't even bring up the hoagies, hot dogs, and their summoning contract. I'm telling you hiruzen the hatake are out to steal your position. hiruzen: I'll humor you this once for old times sake. lol

probably a senju descendant given the totally random potion of awakening

this is where you wish you had read those mystery novels and historical dramas so you have a better grasp on getting around those who plot and a wider range of what others may see as reasonable motivation

need a comedy story involving the beyond multiverse consequences Every time this happens and some martyr who died in vain because the precaution is prevention

mtl requires salt, prunes, shrimp flavored ramen, a sweat lodge with an easy to open window in subzero temperatures, and sour patch kids for those who don't know what the salt and prunes are for. lol

makes sense the other villages followed the leafs example and the forehead protector was actually hashiramas blindfold while the giant aesthetic wood whack amole statue had less to do with combating the giant sussano target and more to do with having enough arms to swat a poisonous insect without looking. lol

going by kakashi, Itachi, and seemingly anyone with a similar name; children mature faster in Naruto so if he can tell he's twelve then he's really eight

just don't fall into the taboo about denoting the extreme bo staff skill of... just about anyone. it's usually a joke for a reason.
