This is the final story to the hybrid series. Please enjoy the first chapter.

13-year-old Nova Butterfly, groaned as she walked down the corridor, "What's wrong, sweetheart?" she looked back and saw her father with 3-year-old Storm holding onto his pantleg walking up to her, "What's wrong Nova?"

"It's the venoms, dad, they're tearing my insides apart!" Nova groaned before leaning against the wall and slid down to the floor, "How do you do it, dad? How do you fight the venoms?"

"Well…at first, I couldn't. I tried everything I can possibly think of until I finally decided to end my life," Nova looked at her father in disbelief, "A short time later, I met your mother, and while your mother and grandparents usually can't stand monsters, your mother took me in and showed me around the castle.

Later that night, the venoms came out to play. Your grandparents wanted to kill me, but your mother wouldn't let them. It took some convincing, but after a while, your mother was declared my mate and the venoms slowly came to an understanding." Nova groaned as she hugged her knees to her chest and buried her face in them, "I don't know what else to say other than until you find someone who you believe will be a perfect mate, there's not much anyone can do."

"Wait…dad, I do have an ideal mate," Marco crossed his arms and stared at his oldest daughter in confusion, "My friend Heinkel, we've been best friends for a few years and-"

"And in order for you to be absolutely sure about that, he's going to have to accept you, both of you. Mewman Nova and hybrid Nova."

"But how can I do that? You and mom always come and get me before the sunsets and Heinkel doesn't know about us," Nova groaned and Storm walked over to her sister, "I can't be sure if he's my mate if he doesn't see the hybrid me, and he won't see the hybrid me because of you and mom,"

Storm frowned and patted her sister's arm, "Okay Nova?"

Nova sighed and shook her head, "Yeah, I'm okay, Storm." She sat back and took a deep breath as darkness covered the land like a blanket and the three hybrids howl as they felt the venoms gain control.

Storm began crying as Nova panted in pain. Marco sighed as he picked up his youngest daughter and rubbed her back, "It's okay sweetheart, it's just the venoms."

"Daddy it hurts,"

"I know, sweetie," Marco looked at Nova and frowned as he saw her looking out the window in pain, "Nova…I…your mother and I will talk later," Nova looked at her father in confusion, "If you think Heinkel is your ideal mate, your mother and I will talk about it and if we agree…we'll let you stay out tomorrow,"

"Really?"

"Don't get your hopes up, both your mother and I have to agree to this, okay?" Nova smiled before hugging her father, "Okay, let's go see what your mother is up to. I'm sure she's worried sick about you two," Nova nodded before the hybrids turned and walked down the corridor.

Star and Marco watched as Nova tried to comfort her younger sister while struggling herself. Marco sighed and looked down at his wife, "Estrella?" Star looked up in confusion, "Nova thinks she found her ideal mate,"

"Really? That's great honey. Who is it?"

"She claims it's Heinkel," Star arched a brow and Marco took a deep breath and shook his head, "But she can't be sure unless Heinkel sees her like this and-"

"And you're worried someone will go after her or she could be mistaken and Heinkel could go after her himself," Marco nodded and Star sighed, "But honey, we knew Heinkel since he and Nova was nine. He's a nice boy,"

"Not only that, but I don't want Nova to face the stigma I faced while I was stuck on earth. A lot of citizens in Mewni can't stand monsters, you, your parents and the help being the obvious exception to that rule," Star frowned and Marco looked up at their daughters, "And it was bad enough my parents and Eclipsa turned me against my family, I don't know how Nova will react if her best friend turns on her because of her condition,"

"I understand you're worried about her, but if we want her to gain control of the venoms, we're going to have to trust her." Marco frowned and nodded, "So should we let her stay out tomorrow to see if she's right?"

"Or we could invite Heinkel over tomorrow so this way we can keep an eye on them and Nova won't have to face the stigma of being a hybrid," Star smiled and nodded, "So…is it decided?"

Star hummed and looked at her daughters, "Nova," Nova looked up in confusion, "Your father and I have been talking, sweetie, and we think it'll be a good idea if you invite Heinkel over tomorrow," Nova frowned and Star shook her head, "We're sorry, honey, but your father does have a point. We don't want you to face the stigma of being a hybrid, but if you're certain that Heinkel is your mate, invite him over to spend the night and we'll see where it goes from there." Nova frowned and nodded before looking back at her little sister.

Hours slowly passed as Storm continued to cry and Nova panted in pain, while Marco lowly growled to himself. Star yawned and nuzzled closer to her husband, "Tired?" Star hummed and shook her head before slowly closing her eyes, "So you're just going to rest your eyes?"

Star hummed again and nodded as Marco smirked and wrapped his tail around her and kissed the side of her head, "Okay Estrella, whatever you say." He looked down at his daughter and gave a sad smile, "How are you girls holding up?"

"We…we're fine,"

"Hurts daddy…hurts,"

Marco sighed and shook his head, "I know sweetheart, but there's nothing we can do," Strom continued to whimper while Nova tried to comfort her younger sister.
