I-Island Incident

The I-Sland Incident is an event that occures when Wolfram and his minions invade and seige I-Island during the I-Expo.

Prologue
The expansive I-Expo event is being held on I-Island. Heroes, scientists, and civilians come together to celebrate technological advancements in the hero world. Popular names like the No. 1 Hero All Might and Nobel Peace Prize Winner Professor David Shield are in attendance.

This attracts the attention of other, more devious entities. Wolfram and his gang secretly infiltrate the I-Expo with the help of a mysterious informant. During the early access event's reception party on the first night of the expo, Wolfram's minions take control of the security system in the central tower. This turns I-Island's security programs, that which rival Tartarus Prison, against the heroes and civilians present.

Wolfram abruptly disrupts the party in person, using restraining devices to quickly subdue all the heroes. He claims all the inhabitants of I-Island as his hostages. The villain promises not to take anyone's life as long as his demands are met. He seeks out David and his assistant Sam before taking them away from the reception hall.

All Might can do little more than watch helplessly, bound on the floor. Luckily, his young protege and the other U.A. students attending the party haven't been caught by the villains. All Might informs them of the dire situation, and after heavy thought, the students decide to save the day. All Might is reluctant to put the students in danger, but he's proud to be their teacher and puts his faith in them.

Incident
Swordkil escorts David Shield and his assistant Sam to the security room. The students try to use the emergency stairs to reach the 200th Floor of the tower but they run into a blockade on the 80th floor. Minoru opens another passageway that alerts Wolfram's henchmen in the security room. Wolfram orders them to use the shutter doors to trap the trespassers.

The shutter doors nearly succeed in trapping the students but Shoto freezes one of the doors and gives Tenya an opening to break through into the botanical gardens. Kyoka immediately notices the central elevator ascending and everyone decides to hide. Two Villains exit the elevator and before long they notice the students. However, the students they discover are Katsuki and Eijiro, who got lost on their way to the reception party.

The Villains quickly get hostile, but Shoto springs into action. He blocks his allies with a shield of ice and raises the others to the next floor using a pillar of ice. Shoto tells the group to continue the mission while he holds off the villains.

Shoto tells Katsuki and Eijiro about how criminals have taken over the tower. Wolfram's duo of minions breaks through Katsuki's ice. The smaller one activates his Quirk, transforming him into a purple hulking beast. Shoto sends a freezing wave at him, which the villains break through using brute strength. Katsuki lands an explosion, but the beast shrugs this off and counterattacks. Eijiro hardens himself and protects Katsuki from the blow, but gets sent flying away as a result.

Shoto warns Katsuki to dodge the next attack, a vacuum wave coming from the other villain. Katsuki evades and Shoto covers him using another wave of ice. The vacuum displaces the ice, forcing Shoto and Katsuki back to back. The villains commend the two boys on their fighting skills and ask who they are. Both Shoto and Katsuki refuse to acknowledge them, saying they don't deserve to know anything about them.

Momo uses her Quirk to create a small explosive that opens a vent on the roof. Denki convinces Minoru to climb through by promising him a harem of women after the incident is over. Minoru climbs the outer wall of the tower and enters the maintenance room through another vent and lets down the latter to help the others up to the next floor.
