Troy Defense System

Troy Defense System names a large-scale trapping and capture apparatus. The Heroes built it in preparation for their last stand against All For One and the forces standing with him. It appears in Chapter 344 and Episode 144.

The system is a set of black metal containers buried beneath the battlefield. Activation drives them upward out of the ground, swallowing most of the Villains and cutting them into isolated pockets. Because the captives were meant to be scattered to different parts of Japan by Warp Gate, each cell carries its own propulsion and rockets itself toward a second set of portals, these produced by Neito Monoma after Copying Kurogiri's Quirk.

Sturdy as they are, the cages were never engineered to hold anyone for any length of time. The Villains rip through in under three seconds and mock the idea that such a thing could restrain them, which is exactly the outcome the Heroes wanted. The cells only needed to stall the Villains while the Heroes took up position and drove the wreckage and the Villains inside it backward into the Warp Gates waiting behind them. A member of the Paranormal Liberation Front points out how absurd it is to burn that much money and hardware on so simple an aim, and his opponent answers that no expense is too great when the goal is beating them, in Chapter 345 and Episode 144.

The Heroes built and fired it. Neito Monoma supplies the portals the cells launch toward, using Copy on Kurogiri's Warp Gate. Its targets are All For One's allies, the Villains of the Paranormal Liberation Front.
