Hello! It's me, the now self-proclaimed #1 Inverse!AU fan (/silly) I just came up with two ideas for Inverse I would like to share.
I forget what you're doing with the Golden Weapons in this AU, but I would like to randomly suggest something. What if the Ninja of Destruction are able to get the Golden Weapons, but the weapons adapt to the sudden change in fate (because the Core Four are out of commission) and "destroy" themselves, transforming into Golden Weapons the Outliers can properly use (Golden Weapons of Destruction, if you will). Here's my take on how the weapons would transform.
Shurikens of Ice → Trident of Waves: The Shurikens will freeze themselves in Ice before the ice quickly melts and erodes them. Then, the water will drip down and rapidly form a Trident by depositing the gold (similar to a stalagmite or crystal).
Scythe of Quakes → Axe of Time: The Scythe reverses time, melting back into molten gold before reforging itself into a golden Double Axe as if it was always that way. (History isn't changed or anything, it just sort of acts like it was always forged as a Double Axe instead of a Scythe) The Two sides of it could control Forward and Backward movement, becoming split like the canon Time Element. The Time weapon being an Axe may or may not be influenced by Krux with a battle axe propaganda...
Nunchucks of Lightning → Bow of Storms: The Lightning holding the two handles disappear before a strong wind surrounds it. This wind picks up a bunch of debris and flattens the handles and reshapes them into a golden Bow. Then, a column of air will form the bow string. Anything shot from the bow will accelerate with the wind.
Sword of Fire → Forge of Amber: The sword melts down into a mass of molten gold. The Forge then takes on any shape the user wishes. Obviously there will be limits, but I can't think of how to balance it well. The reason it's technically just a glob of molten gold is because I wanted Skylor's weapon to be flexible to match her powers. She'll probably carry it as a belt or armor or something like that. Also, the flexibility could also mimic the powers she absorbs or something. IDK Skylor gets to be special because I say so.
I also thought about the first time the Ninja of Destruction pull off the Tornado of Destruction (because I just got to the Tornado of Creation part in Book 1) and I wanted to share my thoughts on what mechs they would "create"! I know they probably wouldn't get any cool mechs because the Tornado of Destruction would need to destroy stuff, but I can dream! (If it does "create" mechs through destruction please tell me how!)
Nya: She would create her spider mech from the Movie. Simple enough. The Trident would probably attach itself on the bottom as a blaster or something.
Morro: Morro gets a helicopter or plane. I can't decide because both are pretty cool options. The bow would either become part of the plane wings, part of the helicopter blades, or part of the controller.
Toby: Toby gets a car (because I think he would be badass drifting around people he's slowed or paused). Specifically, the car is a stick shift because it's a lot easier to do cool car stuff in a manual car. The axe would probably become the steering wheel.
Skylor: Skylor gets a motorbike. The Forge forms the chassis of the bike and then elemental powers (probably just the other elements of destruction the first time it's created) form the rest of the body. Skylor just seems like the type of person to have motorbikes (Also, Nya will probably make a joke about Skylor stealing her thing, lol).
I've been holding onto this ask for a long time because I wanted to draw the weapon ideas cuz I liked them so much but I fear that may take more time than I currently have alas :V
I dunno how the logistics of the weapons changing their elements would work against the lore but let's say with the Core Four corrupted the Golden Weapons just adapt to the Elements of Destruction instead to help keep the balance or something. And I meannnnn if the Tornado of Creation is an invocation of the Green Element's ability to influence change I don't see why the same couldn't apply in the opposite direction for -a harmonized- Tornado of Destruction. The pieces are there and loose but it is a foundation!!
Also Skylor's main weapon is actually a pair of Brass Knuckles sooooo I am not opposed to a golden variant capable of dishing out some extra elemental damage *-*
(also. c'mon. Morro angrily piloting a helicopter with turrets. Someone more skilled than me needs to draw the vision)
Nya: ...Can't you fly already??!!?
Morro: Sure, but I'm not bulletproof either!
Skylor: Neither??? Is a Helicopter???
Toby: Though they are very resilient.
