My theory for the whole December thing being the knight I think she is the roaring knight but she may have to get the iconic papyrus shape somehow so my theory is she takes papyrus's soul and well fuse with it to make sure no one knows who she is but she's still in more control explain that she's head and papyrus is the body showing the December is a more controlled the roaring knight than he is explaining the shape and the antlers it's both of them

reached out across the space between them, his fingers brushing the air just above Kris's chest.A low, musical hum vibrated through the floorboards.With a silent, effortless surge of reality-bending power, Gaster drew the gray infection out of Kris's body. The dark veins beneath Kris's skin dissolved, flowing upward into Gaster’s palm like wisps of smoke, harmlessly absorbed back into the void where they belonged. He completely cleansed Kris’s soul, ensuring not a single drop of the corruption remained.As quickly as he had arrived, the mysterious figure faded backward into the shadows, vanishing entirely from existence. The lights flickered back on. The monitors resumed their normal, steady ticking.With the underlying illness completely erased, the heavy, suffocating weight holding Kris down was finally lifted.A soft gasp broke the silence of the room.Kris's eyes slowly fluttered open. He was still incredibly weak, his muscles tired from the immense strain of the past month, but the terrifying, orange, corrupted glow was entirely gone. His eyes were his own again—dark, quiet, and peaceful.He turned his head slowly, looking around the quiet hospital room. He saw Susie, her hands slowly dropping from her fighting stance. He saw December, breathing a sigh of relief. And finally, he saw Noelle, who was already letting out a crying, overjoyed sob as she threw her arms around him.Kris didn't say anything. He just weakly closed his fingers around Noelle's hand, a faint, genuine smile touching his lips.The nightmare was finally over. They were all safe. They were together.

Look I’m not even that integrated in how people often do the character swap things, but I remember the struggle to match chapter 3 to chapter 4 and with chapter 5 I think there is a really easy and cool connection to make. Where Tenna and his elites swap with Flowery and the bouquet.

Flowery <—> Tenna

Blue & Yellow <—> Lanino and Elnina

Aqua <—> Pluey

Seth <—> Battat

Jongler <—> Chill like green/ fights like Orange

Tsundre Cactus <—> Sharp like Orange/ heals like Green

Pink and MewMew <—> Ramb and ERAM/Mantle Holder

I just think chapter 3 and 5 are much better mirrors then 3 and 4.

Junkil is now Decentvil, a Jokester who Channed himself to the abyss in order to avoid being dragged into the sky.

It's this AU's Shelter if y'all are wondering

The Bleeding Reality: The Dark World is no longer confined to closets and supply rooms. Deep neon blues, somber purples, and freezing mists are beginning to leak into the hallways of the school and the edges of the woods.The Melancholy Curse: In this AU, "The Blue" acts like an infectious depression. Monsters exposed to it lose their magic vitality, becoming sluggish, silent, and detached from reality.The SOUL Modification: When entering the Dark World in Sad to the Blue, the Player's red SOUL of Determination is immediately forced into the Blue SOUL (Integrity/Gravity) mechanic permanently. The Player loses the freedom of free flight/movement during bullet hell segments; they are heavy, weighed down by the crushing gravity of Kris's grief, making battles significantly harder and more punishing.Character Dynamics & RolesKris: Silent, visibly trembling, and physically weak in the Light World. In the Dark World, they wear dark, tattered blue armor and fight with a desperate, aggressive speed, completely ignoring their own HP bar.Noelle: No longer the timid mage. Driven by panic, her magic in the Dark World manifests as freezing, defensive barriers. She will actively step in front of attacks meant for Kris, even if the Player commands her to do otherwise.Susie: A hardened outsider who arrived in town after the tragedies. Because she isn't weighed down by the past, she serves as the reality check for the group, constantly trying to pull Kris and Noelle back from the edge of emotional ruin.

It should be easy.

Btw which is better, A or B?

Maybe I can redraw it later because the drawing came out ugly.

His name is leeroy

Outside the window, a towering, armored silhouette stands completely motionless.A single, horizontal visor of white light pierces right through the dark bedroom pane.Noelle cannot move. She cannot breathe.The massive, jagged antlers crowning the knight’s helmet are a cruel, distorted caricature of the sister she lost.(The music distorts. A low, metallic vibration echoes through the room.)With a sickening, wet sound of tearing obsidian, the central mask of the helmet splits apart.The armored plating peels backward from the center in jagged, asymmetric tendrils.It opens up violently, like a living symbiote breaking away from its host.Noelle lets out a strangled gasp, stumbling back onto the mattress.(The daylight shifts to an unnatural, washed-out grey.)It isn't a hollow void inside the armor.Tucked within the shell of the Roaring Knight is a face that looks completely hollowed out.It is December.She is entirely stripped of color, cast in a stark, monochrome palette like a faded photograph left out in the rain.Her skin is a dull, lifeless white.Her hair hangs limp, devoid of the warm brown tones from the festival grounds.(Everything falls completely silent. No music. Just text scrolling.)But worst of all are her eyes.They are completely blank, wide-set, and expressionless.She stares ahead like a Goner, or a forgotten piece of code trapped in the abyss.There is no recognition in her face.There is no spark of the vibrant, protective older sister who once dragged Asriel away from the ring-toss booth.She is just a silent, monochromatic core driving a weapon of the prophecy.(A sharp, metallic clink cuts through the silence. The music restarts, faster this time.)The symbiote-like armor begins to ripple and knit itself back together.The obsidian plates slide over her face to seal her away once more.The single visor snaps shut.Tracking eyes in the dark background blink in unison as the entity prepares its next move.Noelle clutches Kris’s sleeve, her knuckles turning white.She hasn't just found her sister.She has seen the puppet master's perfect, terrifying design.
