My Hero Academia is a successful and widely popular series that has led to two movies. The first is My Hero Academia: Two Heroes. This movie explored All Might's past, and it showed the consequences of keeping One for All a secret from the user's closest friends. It also focused on the themes of achieving one's dreams and how things may not always work out as initially planned, and the consequences of doing the wrong things for the right reasons.
The second movie is My Hero Academia: Heroes: Rising. This movie depicts the entirety of Class 1A banding together and growing as a team when they are forced to respond to a villain threat in an isolated area. Both movies are enjoyable, but the second movie has a few things that make it better than the first and a few things that make it worse.
10 Better: All Of The Students Are There
In the first movie, some of Class 1A's characters only make a brief appearance. For example, Toru Hagakure is seen with the other girls who didn't get to go to I-Island and suggested that they play Uno's game. In the second, every student is present on Nabu Island, participating in a program designed to give them more experience doing hero work. When the villains arrive, every student's presence is crucial in dealing with the threat, and they all have a chance to shine.
9 Worse: The New Characters
Mahoro Shimano seems like a variant of Kota Izumi, in the sense that she shows disdain for heroes. She is afraid of seeing the people closest to her, getting hurt in an attempt to do hero work. Her brother is also very similar to Eri, as he is a highly valuable quirk that a villain wants to exploit. Melissa Shield from the first movie had a bigger role to play: she gave Deku some much-needed equipment that she made herself, and she is needed to disable a security system.
8 Better: The Students Get To Do Peaceful Hero Work
Most of the time, Class 1A's training is interrupted by villains. While this is the case this time, fans get to see the students shine as they perform various tasks to help the island's citizens. These tasks are simple, and not all of them take much time to complete. This is a nice reminder that being a hero does not consist only of overcoming dangerous situations. As long as they get to help people in need, they are fulfilling their role as heroes.
7 Worse: Plot Convenience/One For All's Inconsistency
To transfer One for All to Deku, All Might made his pupil consume one of his hairs. Deku supposedly passed on his quirk to Katsuki through the blood. Although he showed the required willingness to give his quirk away and fans even saw the quirk disappear from within Deku, he still somehow ends up keeping the quirk regardless.
All Might tries to explain this off by saying that this was thanks to Deku's selflessness or that Katsuki fainted, but neither guess makes much sense.
6 Better: The Side Villains
The side villains in the second movie are adamant opponents, requiring groups of students actually to be able to take them down. Mummy can manipulate just about any matter by turning them into puppets that can attack his enemies. Slice has a deadly quirk that decimates ships, leaving the students and inhabitants stranded on the island. Chimera is even more powerful, as the U.A. students suffer multiple defeats against him. It takes a large group of students working together to bring him down, but they are all unconscious by the end of the battle.
5 Worse: Very Little All Might
All Might makes a minimal appearance towards the end of the second movie, discovering what Deku and Katsuki had to do to defeat Nine finally. However, he had a bigger role in the first movie. Fans of All Might were able to see what he was like in his prime, who is a little different from the All Might viewers are first introduced to.
Fans hoping to see more of him will be disappointed to see that his main role in the second movie is to deliver more plot.
4 Better: Deku And Katsuki Team Up
There was a point in time where the thought of Deku and Bakugo working together was a complete joke. They still butt heads a lot in this movie, but they quickly acknowledge their priority of protecting the island's people, especially the child that Nine is targeting. Fans get to see how the duo wields One For Altogether and was surprised by how well the two can work together. Bakugo was able to make great use of the quirk for the short amount of time he had it, boosting it with his natural explosion quirk.
3 Worse: Weaker Message
One of the movie's core messages is that even though every quirk is useful and that just about anyone can become a hero. Deku encourages Katsuya Shimano not to give up on his dream of becoming a hero. However, this message is focused on in the main series, so the movie does not teach the viewer anything new. In the first movie, Melissa Shield was completely quirkless, yet she found a way to help others by creating inventions meant to assist heroes. The first movie pointed out that not everyone is lucky enough to have a "One For All" fall into their laps, but people can find other ways to achieve their dreams through hard work.
2 Better: Katsuki As A Hero
Despite knowing the villain's goal, Katsuki Bakugo doesn't even consider the possibility of handing over the person that the villain wants. He insists that the only solution is to defeat Nine, and despite his distaste for his classmate, Katsuki is even willing to put up with Deku until the whole ordeal is over. He goes to great lengths to defeat the villains, pushing his body to the absolute limit. He even seems to have gained the respect of Mahoro Shimano, who had previously disliked heroes.
1 Worse: The Main Villain
When comparing the two main villains, Wolfram, seemed much more intimidating. Nine spent most of the movie fighting his illness, making him seem more vulnerable even though he gave Class 1A's students a hard time. Despite not having the same number of quirks as Nine, Wolfram had a powerful quirk that allowed him to manipulate metal to his will. Obtaining an item that boosted his powers made even All Might struggle to defeat him, as he quite literally had an iron defense and offense, as well as a cold and sadistic personality.
