Bakugou might react with his usual anger. He could lash out at the bullies verbally or even physically, which might make the situation worse. For example, if someone makes a snide comment, he could respond with a loud and aggressive retort.
Well, Bakugou's development in Bakugou One For All fanfics can be quite complex. Initially, he might struggle with the idea of having a power that wasn't his own. But as the story progresses, he starts to adapt. He becomes more empathetic as he realizes the sacrifices that were made for One For All to be passed down. His relationships with his mentors, like All Might, also change. He becomes more receptive to advice and starts to see the bigger picture of being a hero, not just in terms of strength but also in terms of character and leadership.
Bakugou might be initially shocked. He's used to Izuku calling him 'kacchan' for so long that it's become a normal part of their relationship. So, when Izuku stops, it could throw him off balance.
His height was 155cm according to the official information. However, some people thought that the height in the official data might be exaggerated, and the real height might be around 152cm. Therefore, his real height might be 152cm.
Typically, a story in a building is around 10 - 14 feet (3 - 4.3 meters) in height. This can vary depending on the type of building, whether it's residential or commercial, and architectural design.
He might become more responsible. Since One for All is such a significant power, he'd have to step up. He couldn't just be as reckless as he used to be.
His relationships with other characters can also develop. For instance, if he rescues you, there could be a newfound bond between you two. He might be more open to working as a team or showing vulnerability around you. This is a big step for Bakugou as he's usually so prideful. He could start to trust others more, which is a sign of growth in his character.
His aggression might become more unhinged. Without the moral compass of the hero side, he could be more willing to use excessive force. He'd still be competitive, but now it would be against heroes instead of his fellow hero trainees.
Bakugou could use his words. He might tell Deku that he believes in him. For example, he could say 'Deku, you may be a nerd but you're a strong nerd.' It's a backhanded compliment but it shows he has faith in Deku.
Some characters might try to understand Deku's motives. Kirishima, who was close to Bakugou, would be angry at first but might also try to find out if there were any extenuating circumstances. However, many would be afraid of Deku, seeing him as a threat now that he has killed one of their own.
