OK SO 2nd part with my main idea
So, maybe it's Isaac? Mentioned in the divine comedy, check... and thats where the simple checks end.
Isaac stood out to me because I feel like he could reasonably have specifically a 'revenge' quest on the angels. Let's say we reinterpet the biblical tale a little bit, and Isaac is truly killed on that mountaintop. He watches from heaven as the angels, maybe even Gabriel if we're feeling spicy, provide Abraham nothing but a hollow apology and a declaration of his faith. Isaac lingers in wrathful stupor for millennia, not for his father, but the angels. He abides in heaven like a husk, until his gnashing anger gets him banished. Maybe he even killed another angel up there, who knows.
On his descent he found his body contorted and plastered back upon his shattered virtuosity, thrown back into a shell too small for him now. Stretching contorting, both the shell and his soul to match, to little success. He landed in Treachery for his violence against his fellow angels. Before any punishment could begin, he wrended his father's knife from his abdomen, and began his rise to pierce the heavens for himself. (Yeah, I won't lie, I stole this a little bit from Jogolord, rising the layers of hell is just so damn cool)
Treachery as a cold unending wasteland, a layer made for Lucifer, bears hardly any respite. That is, unless you know where to look. Such is the point after all. Across the tall mountains are small cuts and punctures, akin to that of someone sacrificing stones. Within are full encampments, burnt out fires, and journals written in a code meant to be only understood by the children of mankind. Shockingly, that category, meant to mean humanity, would go onto contain machines, so don't worry your blue little head off, you get to read the lore.
Isaac worked slowly, a slaughter calls for response, so he cut down in silence, and only killed those who would slow his eventually flight from this layer. If he was lucky, he would run unnoticed, and the rise back to heaven would be easier, his absence in Treachery pinned to a simple death. Of course, outside of his own perspective, the angels knew to worry the moment he landed, constructing The Flesh Binding. A stark improvement upon both the prison and the panopticon, not being made of one solid body, but countless tendrils tangled and festooned upon eachother. If one falls, another shifts to make up the distance. If it came down to it, Isaac's soul would not move an atom. No running or hiding for him.
The funniest part of his silent revenge plan, was that it worked. Hell itself failed to notice the vengeful husk, and his ascent was made easy. His sole stop was that Limbo, the place his father raised him. It couldn't have looked like this when he was a boy. It was... a sick joke. Fuck this. This is heaven's fault assuredly. Crackling music pierced his ears which once bore his father's promise of God providing a goat. Sickly speakers.
He cut down the speaker into swarf, the empty space drowned by silence other than the sounds of his own blood in his ears...
And the shift of metal against metal.
Gabriel spoke to the rageful son, hushed and solemn, "I'm sorry."
The scar across his torso, the last gift the earth gave him, suddenly stained his stomach with blood again. Gabriel's sword jutting out his sternum, he collapsed.
SO, that ain't a theory, that's creative writing, what do I think an Isaac Prime would look like though?
Akin to Sisyphus's head, let's give him a glowing mark! Specifically on his sternum, but let's make it white. I heard another theory which focused on the other primes' subcolors representing the sulfur and mercury skull, two of the three primes of alchemy. Salt is the 3rd, and the salt skull's white. For a main color, red might work, following the whole, eternal rage thing, but I think a dried almost purplish crimson would maybe work better. Symbolizing a necrosis found in bearing rage that long. More so, it contrasts the white nicely. Also salt represents the body, and I think him being a sacrifice does this well.
Fight wise, Isaac Prime focuses on high speed and area control. So you know... torture. (I'm so bad at dealing with area control enemies.) By doing this, it preps the arena for one solid attack, akin to his flight from hell.
Voice wise, he needs to sound young. Both primes have sounded wise and experienced to war and control, both dying as literal kings on earth. Isaac shouldn't be like this, he died as a young boy, and for that, should sound like an inexperienced soldier. He's his commissioner, general, and footsoldier, but he still sounds freshly recruited. His mind has never left that mountain, never freed of his binding, so let his voice reflect that. Don't make him sound 9 though, the ultrakill community would fucking massacre his monologue. Treble voice with low gravel would get the idea across and still give a good monologue.
Have him say some shit like. "Child of man. I feel your rage. I know the anger that must fuel you to get this far. You've fell two heaven slayers, and killed more angels than whole layers would see in eternity. Your plating glimmers with the blood of an archangel. But. My child. Heaven's blood is mine."
Put that shit as part of his monologue. His main attack style's gonna be focused around his sacrificial dagger, and headbutts. Why headbutts? Sisyphus does hands, Minos does legs, so I think heads is a good option remaining. Because. thats how goats fight.
Yeah give him goat horns too maybe. Really drill in the goat comparisons.
Hates the angels, has a reason to hate V1, and depending on treachery predictions, has a layer for him to star in.
Name his track either FORESIGHT or ANARCHY.
2 Greek mythos primes, and then Isaac as a Christian one... hm.
Primes don't fight with weapons!
Unmentioned in the story so far... sigh...
The Binding of Isaac, yes that's the name of the biblical story aswell, but that sure as hell is not what I think of first, let's be honest.
I like this guy though, tell me what yalls think :)
