Burst

Burst is an unnamed Quirk used by a Near High-End Nomu.

Description
Burst seemingly allows the user to explode, resulting in an explosion of bright light. Due to the user exploding, this Quirk is seemingly a one-time use.

Usage
After taking most of the brunt of the damage of the Tiamat missiles, "Tomura Shigaraki" commands the Nomu to Burst, leading to its last remaining bits exploding, creating a distraction against the fighter pilots and allowing "Tomura" the opportunity to catch Star and Stripe off-guard.

Trivia

 * This Quirk shares many traits with the Self-Destruct Quirk All For One secretly gave to Lady Nagant and the Self-Detonation Quirk used by the Bombers, as they are all Quirks that can be activated by a third party, and leave the user incapacitated in some way. As all three can be traced back to All For One in some way, it is possible that these Quirks are related, if not artificial duplicates of the same Quirk.
 * In the cases of Lady Nagant and the winged Near High-End, it is never explicitly stated that their detonations were caused by Quirks they themselves held. It is thus possible that they instead detonated due to the effects of Quirks held by All For One and "Tomura" respectively that could cause another target to explode, similar to Landmine.
