Some Stratosfear concept and design stuff. I'm surprised I haven't shared a lot about my af2 au on Tumblr actually.
Just thinking about them being a living weapon, considering Celesteal fitted them into the villain role of the Narrative. That, or the tragic villain. Regardless, this form is excellent for combat during their boss fight, which is pretty much the only appearance they made in AF1. Yet despite their weapon, they are pretty vulnerable with little to no armour for protection. Easy for the Star Savior to make a killing blow before the timeloop restarts again.
I also like the idea of tattoos or engravings on their arm to represent the stars they stole. Idk. Large tail for optimal stinging and claw to grab prey. Celesteal made them a mouth that can open up to reveal sets of sharp teeth for chomping.
Maybe they also have the ability to shapeshift? Idk this is just an excuse for me to retain the old design I had for them lmao. Because they're the Point of shadows and stingers or something. But they are non-solid at the touch; therefore, they definitely can't use it for fighting. Idk something something morphing into shadows for stealth and dramatic flair for a more cinematic Narrative. Somewhere along the lines.
During post-Pointification perhaps they have a form to look more friendly to the Points? I don't think them being a former feared villain who turns out to be controlled by Cyalm the whole time would make them a huge hit among the Points. Especially when they look like they can easily kill or maim you. But remaining in this form for a prolonged period of time can tire them out.
Anyway those are my headcanon rambles! Bonus Stratoshine doodle below
