Black Hole allows Thirteen to create small black holes through her fingers.
The black holes suck in and disintegrate any matter at the atomic level, as well as certain forms of energy, such as light. In combat, Thirteen can use this ability to prevent enemies from escaping her range by sucking them towards herself.
Due to its nature, Black Hole is highly volatile and dangerous, having a lot of potential to kill living beings or cause large collateral damage on structures if not regulated properly. Should someone get caught by the suction with no way to escape, Thirteen must deactivate Black Hole to avoid obliterating the target, leaving herself open to a counterattack. Due to that restriction, Black Hole is unsuitable for close combat.
Thirteen is not immune to the effects of Black Hole and will get disintegrated like any other object caught by the range of suction, so she has to be extra careful while activating it. Surviving Black Hole is not impossible if one only gets briefly exposed to it, but victims will be left in critical condition.
Thirteen uses this Quirk mostly for removing wreckage caused by disasters during rescue missions. Because all absorbed material gets reduced to atoms, there's no need to dispose of it any further, which speeds up the cleanup process.
Thirteen, being a hero specialized in rescue missions, is not very experienced in utilizing Black Hole for battle purposes despite the Quirk's strength. She prefers to use Black Hole solely as a method to stop enemies from slipping away, turning it off immediately if the target gets too close to the disintegration range, even if this ends up being disadvantageous for her.
