The Buster Union was a team of Pro Heroes from My Hero Academia Vigilantes.
The Buster Union was made up of five heroes, and at the time it was considered one of the hardest-hitting hero teams. Their hero agency was a battle-oriented one, and they used to prioritize interns with powerful Quirks useful for battles.
Each member of the Buster Union wears their own hero costume. They used to go to the battle riding on four-rotor drones.
They were considered a powerful team since the Quirks of each member were highly offensive, being especially destructive when attacking at the same time. Almost all members of the Buster Union had unnamed blast Quirks.
