Hyper-Density Seals are weapons utilized by Sir Nighteye.


Rappa's Clone defeated

The forceful impact from a seal thrown by Sir Nighteye.

Sir Nighteye possessed many small stamp shaped items that weighed five kilograms each.

By throwing the seals at extreme speed, Sir Nighteye could attack from long range and supplement for his lack of a physical Quirk. A seal tossed by Sir Nighteye was powerful enough to destroy one of Twice's clones in a single hit.[1]
