Adrien might become more protective. Usually, he's carefree to some extent, but with Marinette pregnant, he would be constantly on guard. For instance, he'd be extra vigilant against any potential threats, even the smallest ones. He may also become more serious about his responsibilities as a future father.
Both of them could experience a growth in their maturity. Adrien might start to think more about long - term plans for their family, like where they will live and how they will support the baby. Marinette may become more nurturing, not just towards the baby but also towards Adrien. She might start cooking more healthy meals for him and taking care of his well - being more attentively as they are now a unit about to expand.
Marinette, on the other hand, could become more moody. Hormonal changes during pregnancy are common, and this might make her more irritable at times. However, she would also show great strength. Since she's Ladybug, she has that inner determination. The pregnancy might make her even more determined to create a safe world for her child, so she could be more proactive in fighting akumas.
Adrien as a merman might become more in tune with the natural elements of the ocean. He could be more carefree and wild, as opposed to his somewhat reserved self on land. His love for adventure could be amplified, and he might be bolder in expressing his feelings, especially towards Marinette. Marinette as a mermaid could be more confident. The underwater world gives her a new sense of freedom, and she's less worried about the small things that bothered her on land. She might also be more assertive in her relationship with Adrien.
They would become even closer. Their love would grow deeper as they are about to start a family together. There would be more tender moments between them.
During the pregnancy, Conner might become more patient. He has to deal with Kira's mood swings and hormonal changes, which makes him learn to be more understanding. Kira could become more introverted as she focuses more on her body and the baby growing inside her. She might spend more time at home, reflecting on the changes in her life and preparing mentally for motherhood. This could also make her more sensitive to her surroundings and the people around her.
Jake might become more protective. He was always a bit of a goofball, but now he's serious about keeping Amy and the baby safe. Amy, on the other hand, could become more emotional. She was already a strong - willed person, but pregnancy hormones make her more sensitive at times.
Max might become more protective. Since she is usually strong - willed and a leader, this pregnancy could make her even more fierce in protecting her unborn child. Fang could become more nurturing. He has always been a bit of a loner but now he would be more focused on taking care of Max and the baby.
Severus, who was always a bit brooding and reserved, might become more protective. His focus would shift from just his potions and the dark arts to ensuring Minerva's and the baby's safety. He would be constantly on guard. Minerva, on the other hand, usually a strict and no - nonsense teacher, could become more emotional. Small things might make her cry or get overly excited. She might also be a bit more lenient with her students as she experiences the softer side of life through her pregnancy.
Justin might become more protective. Since he's usually logical, he'd start making detailed plans for the baby's future right away. His studious nature would make him research everything about pregnancy and parenting.
Alejandro may become more selfless. His actions would be more centered around Heather's needs and the well - being of the baby. He could sacrifice his own interests like his social life or certain hobbies. Heather might transform into a more patient person. Given her normally impatient and sometimes abrasive personality, the pregnancy could teach her to be more patient, especially when dealing with the physical and emotional changes she is going through.
Tony, being the genius he is, would probably approach the pregnancy with a scientific mindset at first. But as time goes on, he might become more emotional and protective. Loki, on the other hand, would likely be more secretive about it initially. His mischievous side might still show, but he'd also have moments of vulnerability that he usually hides.
Carly might become more protective and nurturing. Since she's always been a bit of a leader and a caring friend, this new role of soon - to - be - mother could enhance those traits. She could be more cautious about the people she surrounds herself with and more focused on creating a safe environment for the baby.
