Undertale Crossover Fanfiction Novels & Stories

Later, her crystal ball revealed that the fated mate wasn't in this world at all — they existed in my reality. So she cast another spell in secret, pulling that person across the divide and dropping them somewhere in the werewolf world. I spent the next three years searching for the person I'd dragged here against their will. When I finished telling Lucian the whole story, his knuckles went white on the steering wheel. I could see the storm of emotions playing across his face in the rearview mirror. "It was wrong of me to pull you into this world. Now that the prophecy has been averted, I'll have the Witch open a portal and send you home."

The cathedral trembled as darkness bled from the floor like ink in water—curling tendrils of shadow slithering up the walls, devouring the stained glass until the only light left was the glow pulsing from Elara’s veins. Dain shifted protectively in front of her, sword steady, but his voice carried a tremor. “This isn’t just magic. This is a realm crossing.” “Elara,” Kael said urgently, stepping beside her, “if they finish this ritual, their world won’t just touch ours—it’ll consume it.”

Johnny picked up the mate-bond dissolution application and flipped through it again and again. "Impossible! I've never signed this! This has to be forged! A fake!" I shook my head and let out a frigid chuckle. "If it's forged, do you think the alliance wouldn't find out? Are you questioning the alliance's capabilities?" Johnny's eyes turned red as he rushed at Zack, grabbing him by the collar. "What did you do to make Carla want to be your mate?!"

Together, they symbolized the unity between the werewolves and lycans, bridging the gap between their two realms. As the celebrations continued, Alessia found herself reflecting on the transformative journey she had undertaken. She had grown from a young maid with unrequited love to a powerful and influential figure within the Convergence. Alessia's dreams of being with Phoenix had faded into the background, replaced by a newfound purpose and a love that surpassed her wildest imaginings.

I glare up at Levi Crosswalk, hatred tightening every muscle in my face. "I reject you, Levi Crosswalk, and I will never be your mate—in this life or the next!" I spit, venom dripping from every word. His jaw clenches. His hands curl into fists. "And I reject you, Anastasia Purrey. I hereby break the mate bond between us. You’re free to prostitute yourself wherever you choose." His words are cold, cruel, deliberate. The insult lands like a slap. I raise my hand—rage burning in my veins—but he catches it midair and yanks me close. Too close. I can feel his breath against my cheek.

“You no longer have a family, money, or a legal identity. You are a fugitive accused of terrorism. When I am finished with the wolves, no one will remember Elaine Thorn as an heiress or a Guardian.” He crouched in front of me. “You will only be my fucking pet.” The cocoon closed again when he tried to touch me. Talus raised one hand. My mother’s blood moved across the floor, drawing a black symbol around us. “Now,” the warlock whispered. Pain exploded through the back of my neck. The mark of the sacred vow went dark. Arsel disappeared. Not the way Leo had disappeared from him. Worse. It was as though someone had cut the universe apart at the exact place where his existence began.

Damien adjusted her hair with surprising tenderness. “Whatever happens in there,” Kael said, looking at both of them, “we face it together. No regrets.” “No regrets,” Damien echoed. Serena smiled through fresh tears. “No regrets.” They stepped out of the greenhouse hand in hand — a werewolf, a vampire, and a witch, bound by blood, grief, love, and growing desire. The final descent into the Nexus awaited. As they approached the glowing archway once more, the fusion creature had grown even stronger, now absorbing the bodies of fallen infected around it. It blocked the entrance completely and spoke with a chilling new clarity:

She had looked at Amelia like she had lost few screws when Amelia first told her, but then, Samara believed her when she retold everything. Samara was the one who made the spell so that Colton wouldn't feel that she was his mate. Samara also had packed a lot of herbs for various reason. "Do you know you can make a wolf from shifting if he is poisoned with Allendore and Mandrake root? It affects the connection between the wolf and the man, and make the human hallucinate, and he would feel like he was shifting, but he wouldn't be." Amelia's eyes glinted coldly and Cilia gave her a shuddering look.

"Yes, Kael. Blood runes in the east woods—marrow god's work. We scout now. Your experience with cults makes you ideal. Ready to run with me?" Kael's gray eyes intensified, the bond's warmth deepening. "Always, Alya. Ash is eager. Lead the way." They set off into the forest, the path winding through dense pines, the ground soft underfoot. As they ran, their human forms blurred, shifting mid-stride—Alya's body rippling into Ember, auburn fur gleaming, fiery eyes ahead; Kael becoming Ash, gray pelt flowing, scarred muzzle alert. They wove through the pines, branches whipping past, the stream's gurgle growing louder, their mind-link brushing—Alya's desire flickering like a shared flame.

’ Scarlet answered. ‘Speak plainly. You know I don’t care for riddles.’ I huffed. ‘Kurt isn’t the only connection the child has triggered. There is another, through Kurt.’ Scarlet rolled her eyes at me. I frowned and focused again, looking at the link connecting Talia to Kurt. And then I saw it. My nostrils flared with anger. A link branching off to that hunter bitch. There’s only one way Talia would have a family link to her. Kurt marked and mated with that bitch! How dare he! I told him he was mine! And he dares to mate with that lesser life form!
