[Western Crossover] Watching from the Shadows

Seville is a species that lives in darkness. He came to Earth to father superior offspring. He should have carefully chosen his mate. But the first time he saw the boy imprisoned in the dungeon, Seville couldn't help extending his tentacles: [Will you be my mate?] * Jason refused the monster without hesitation. Tenderness was always a hunter's trap. A nest, being turned into a breeding vessel, losing his freedom completely. He didn't need to think twice to know what happened to people tempted by monsters. He held on to hope. Bruce would come to save him. He wouldn't give in to the Joker, and he didn't need to make a deal with a monster. Until the new Robin's photo was thrown in front of him. When the crowbar came down again, he accepted the monster's invitation. "Take me away." * He thought the monster would take whatever it wanted from him without restraint. But the monster kept working to restore his health. Jason: He must be fattening me up before eating me! Seville: Worried about his knight's anorexia again today. * Jason never forgot that the monster's purpose was to reproduce. He prepared himself to have another little monster growing inside him. Ten months passed, and nothing happened. Meanwhile, Seville's belly gradually grew larger. Jason: ? Tentacles drew Jason close to listen to the baby's heartbeat. Seville smiled tenderly: [Our child is right here.] Jason: ??? * Good news: the baby was born. Bad news: the child was a handful. After stopping his daughter from bombing Arkham yet again, he threatened Seville: "If you don't keep your daughter in line, we're getting divorced." The tentacles wrapped around him pitifully. Jason remained cold: "Pouting won't help..." Seville: QAQ Three seconds later, Jason couldn't help laughing and let himself collapse into a pile of tentacles. A cool, icy sensation spread across his face. Seville: (////v////) * Through countless days and nights, Robin's dignity, pride, and ideals were crushed. The Arkham Knight gave up everything, selling his soul for revenge. He never imagined that a monster who couldn't understand human hearts would piece all those fragments back together, one by one. * Batman, appearing from who knows where: "I do not approve of this marriage!" The alien must have a scheme! "Grandpa?" The little girl gazed at him with big, round eyes. Batman looked down at the tiny girl, who didn't even reach his knee, and fell silent. Reader's Guide: 1.
