Raven would likely first try to use her telekinetic and magic powers to break free. If that doesn't work, she'd probably start to analyze Red X's motives. She's a very intelligent character.
The reactions of pro heroes to Deku fanfiction could vary greatly. Pro heroes who are more outgoing and friendly, like Mirio, might actively seek out Deku fanfiction just for fun. He could be the type to laugh out loud at the creative and sometimes wacky ideas in the fanfiction. However, more serious pro heroes, such as Aizawa, might initially be skeptical about the whole concept of fanfiction. But if the fanfiction has some deep insights into Deku's character and his journey, Aizawa might start to respect it more.
She may be initially angry. Raven values her personal space and boundaries, and Beast Boy kissing her neck without permission could be seen as a violation. However, as she processes her feelings, she might realize that there are some underlying emotions she has for him that she has been denying. So, after the initial anger, she could start to feel confused and a bit flustered.
The theme of the underdog and the idol is also common. Izuku is the underdog, and the female pro hero is someone he looks up to. Their relationship then blurs the line between admiration and love. For example, if it's with Mirko, Izuku admires her brash and fearless fighting style. As they interact more, their relationship can change from that of a fan - idol dynamic to a romantic one. There can also be a theme of sacrifice, where either Izuku or the female pro hero is willing to sacrifice for the other in a dangerous situation.
Beast Boy would definitely be one of the first to react. He and Raven have a special bond in the Teen Titans, so if Raven gets hurt, he would be extremely worried. He might use his shape - shifting abilities to quickly get to her side or try to find help.
Some might feel honored. They see it as a form of recognition of their importance in Deku's story or in the overall My Hero Academia universe. For instance, Iida could see his friendship with Deku being explored in a fanfiction as a compliment to their real - life bond.
Their friends would probably be very excited. They might bring gifts for the baby, like special toys or clothes. For example, Starfire could bring some alien - made baby clothes that have unique properties. Cyborg might build a high - tech baby crib with all sorts of safety features and fun gadgets for the baby to play with.
One great place to find such fanfiction is Archive of Our Own (AO3). Just search for 'izuku x female pro heroes' there and you'll get a bunch of stories. Some popular ones often involve Izuku paired with Uraraka in a more heroic - duo - turned - romantic setting. Another might be Izuku with Mt. Lady, where the height difference and power dynamics can create really interesting stories.
Starfire would be overjoyed. She's always been the emotional and positive one. She would probably throw a huge celebration for them, with lots of alien delicacies and bright decorations. She might also give them some advice about love based on her own experiences with Robin.
Green Lantern would use his power ring to create various constructs. He could create a large, impenetrable cage around Superman to stop him from escaping with Batman. He'd also use his ring to scan Superman for any signs of external influence, like magic or some sort of alien technology that's making him act this way.
