Explosive Hot-Heads

Explosive Hot-Heads is the het ship between Katsuki Bakugou and Yang Xiao Long from the My Hero Academia and RWBY fandoms.

Canon
As Yang and Katsuki are from different series, even though both of their home universes have superheroes, they have never met in canon.

Yang and Katsuki are both blondes that have red eyes (part-time for Yang) and explosive powers who are easily angered and have an involvement with the main character. They both go to top-notch schools where they learn to fight. They also eventually have some significant moments which leads to them changing and becoming somewhat less angry. For Yang it was losing her arm, and for Katsuki it was being defeated by his rival. Some of the people in Yang's group of friends are a little similar to Katsuki's in traits, personalities and backstories.

Fanon
Explosive Hot-Heads is one of the well liked ships of the RWBY/MHA crossover fandom. Some fanfics and art have the two existing in the same universe, where they fight.
