The 'culture clash' trope is quite popular. Characters from the two very different universes have to deal with the differences in their cultures. For example, the social hierarchies in Hogwarts compared to the hero rankings in My Hero Academia. Additionally, the 'hidden heritage' trope can be used. Maybe a character in My Hero Academia discovers they have a connection to the wizarding world in Harry Potter, like having a wizard ancestor. This adds an element of mystery and self - discovery to the fanfiction.
A really common trope is the 'team - up against a greater evil'. The heroes from both universes join forces to fight a super - powerful villain that neither could handle alone. It's a classic but always exciting. There's also the 'mentorship' trope. For instance, Dumbledore could mentor All Might on how to handle the pressures of being a symbol of hope, or vice versa. This trope allows for a lot of character development and exploration of different leadership styles.

Another is the 'fish - out - of - water' trope. When a character travels to a different time period, they have to adapt to the new ways and rules.
