Episode 10

Encounter with the Unknown is the tenth episode of the Boku no Hero Academia Anime.

Summary
After the villains appear in the plaza of the USJ, one of the villains says that All Might was supposed to be here according to the curriculum they procured yesterday, which causes Shouta to realize that they were the ones who infiltrated U.A. Another villain is shown to be disappointed that All Might isn't here and wonders if All Might will show up if they kill the children.

Shouta takes charge and orders Thirteen to evacuate Class 1-A and try calling U.A.. Shouta goes to fight the villains and defeats many of them quite easily due to his specialty in one-on-group battles.

Meanwhile, Thirteen and Class 1-A attempt to evacuate, but the villain called Kurogiri stops them, telling the students and Thirteen that they are the League of Villains and that their goal is to kill All Might. Katsuki and Eijirou attack Kurogiri but fail to do any damage. Kurogiri uses his Quirk to teleport most of the Class 1-A students to different areas of USJ.

Izuku is teleported to the Flood Zone area of USJ where one of the villains immediately try to devour him. However, Tsuyu attacks the villain and uses her tongue to grab Izuku and throw him onto a ship. She also throws Minoru onto the ship as well and then climbs onto the ship herself. After thanking Tsuyu for saving him, Izuku wonders why the villains want to kill All Might. Seeing as how thinking will not help, Izuku declares to Tsuyu and Minoru that their only choice now is to fight and win, much to Minoru's shock. Thus, the battle between Class 1-A and the League of Villains begins.

At U.A. in the nurse's office, All Might tries to contact Thirteen and Shouta but is unable to. All Might decides to go to the USJ in a few minutes. However, Mr Principal arrives and tells All Might to relax. Mr Principal starts to talk about educational theories with All Might noting that he hasn't changed one bit.

Meanwhile, at the USJ, Thirteen notes that they cannot make contact to the outside world at all. Thirteen orders the Class President Tenya to dash to U.A. to tell the teachers there what is transpiring and get them to come and help. Tenya is skeptical, thinking that running back to U.A. while leaving behind his classmates would be cowardly and disgraceful. After some encouragement from his classmates and Thirteen telling him to use his Quirk to save others, Tenya decides to dash back to U.A.. Kurogiri overhears their plans and goes to stop Tenya, but Thirteen stands in Kurogiri's way. Kurogiri and Thirteen prepare to battle each other.

At the Flood Zone in the USJ, a shocked Minoru criticizes Izuku's plan to fight and win, but Izuku ignores him and begins strategizing. Izuku concludes that the League of Villains doesn't have information on their Quirks and while the League of Villains beats them in experience and numbers, they have the element of surprise on their side. Tsuyu and Minoru reveal the powers of their Quirks and Izuku uses this knowledge to plan a strategy. After one of the villains strike the ship, the ship begins breaking apart. Izuku jumps off the ship and puts his strategy to work, using Delaware Smash on the surface of the water, causing the water to spread out. Tsuyu then grabs Izuku with her tongue and Minoru throws his sticky substance into the spread out water. The spread out water converges in the center along with Minoru's sticky substance (with the villains being pulled in), causing all the villains in the water to be stuck together by Minoru's Quirk. With the villains stuck together, unable to do anything and thus defeated, the three students make their escape, with Tsuyu saying that they were impressive.
