Vanguard Action Squad Invasion

The Vanguard Action Squad Invasion was an event that took place after the First Year's Quirk Training Camp and during the Forest Training Camp Arc.

Prologue
Tomura Shigaraki receives the location of U.A.'s Quirk Training Camp from All For One. Giran meets with Tomura and Kurogiri to confirm a shipment of equipment for the League of Villain's new Vanguard Action Squad. With all of his pieces and prey in place, Tomura sets his evil plan into motion.

The supplies are delivered to Tomura's new allies. Dabi, Himiko, Muscular, and Mustard meet an undisclosed warehouse where they receive their new gear. Muscular wants to act but Mustard reminds him that it's too early to attack and that the squad isn't supposed to do anything flashy. Dabi mentions that Tomura acted like a spoiled brat when they met, but now he's taking charge. Eager to follow Tomura's lead, Dabi says that the coming attack is a warning shot to condemn the false heroes and secure a new future for society.

Several days later, the Vanguard Action Squad rendezvous on a mountain overlooking the U.A. Students camp in the woods. Equipped with new gear engineered from the black market, seven of the villains get together and prepare the invasion. Once again, Muscular states he's eager to attack, but Dabi says they will wait for the three remaining villains to join their party.

Dabi states that the League of Villains made a mistake during the U.S.J. Incident by relying on a bunch of random thugs. He believes a small group of elite villains is more effective at destroying their enemies sense of peace.

Incident
The Vanguard Action Squad invades the Beast's Forest on the third day of U.A.'s Quirk Training Camp. They start the attack when Mustard fills the forest with poisonous gas and Dabi sets another large section of it ablaze. This signals the others to start moving out. Spinner and Magne are tasked with dealing with the Wild, Wild Pussycats hero team. Magne quickly subdues Pixie-Bob by smashing her head with a large iron rod and knocking her out. Muscular searches for a vantage point and happens upon Kota Izuma overlooking the burning forest.
