I want the FMR gods to be niceies and friendly but I think I’d make them fightable in the hypothetical game. They’re totally optional and getting to them isn’t super easy but if you get strong enough and you ask some of them might come over for a brawl.
It’s not like ‘prove your power and worth’ it’s just ‘oh you wanna spar? Alright little man* let’s fuckin spar’
They’re way more difficult than every other boss in the game by far and there’s no reason to fight them except to say you did.
Geograus has very strict attack patterns that are easy to learn (if very difficult to dodge, and moderately hard-hitting), whereas Aerus just throws a bunch of random shit at you however they feel. Hydronus has the most distinct two phases because he flips intensity from ‘a calm pond on a summer day’ to ‘the raging ocean during a tropical storm.’ Aphotious has a lot of ‘trick’ attacks that they use kind of at random. Lumious is the easiest because they’re just here to have fun and don’t have much on the line so they kinda go easy on you. Thermaius also intends to go easy on you since it’s for fun but he gets all fired up (haha) after you get him to half health and then he’s going all-out
Arcanus would be the easiest fight to get to (once they’ve reached godhood, officially), and he would would sort of ‘learn’ from your fighting style, from the moment he’s created, to best challenge you. It’d probably have to be a thing where the ai (not generative ai. The programming that’s been used for enemy NPCs in games long before generative AI bullshit came out) chooses between defense/offensive and melee/ranged/magical fighting styles, as opposed to being perfectly tailored to the specific player because I’m sure that’s way too complicated. But she definitely does an input read where if you try to heal she goes ‘EAT FIREBALL LOL’ like the scrawny godskin guy from Elden Ring (noble? apostle? I forgot which)
If we make it to the moon moon then Devudu, Theós, and Unkulunkulu are also available to fight but they know less about you and aren’t too sure about throwing down with a mortal so it takes a lot more convincing. But Unkulunkulu is very unpredictable and tricky and by that metric alone would probably be the most difficult one to fight. Theós is definitely going super easy on you but she’s also blinding you and making it really difficult to see so you’re likely to just run into their attacks. Devudu is a lot like Geograus but the arena floor changes from rock to mud to knee-deep water and then laughs when you inevitably get tripped up. Like ‘hehehehe you thought I’d go easy on you didn’t you? Fool’
