Harry keeps getting into danger causing some of the more involved parents (ie. PTA Karens) to demand that something be done. Invented by famed artificer and enchantress Appoline Delacour, a perfect sphere of glass is etched with thousands upon thousands of runes and layered with hundreds of charms. The end result is the newly christened "Hexed Unbreakable Nullification Kernel" (HUNK). To protect both Harry from the world and the world from Harry, it was decided that Harry would be the first HUNK. And thus "The Bubbleboy Who Lived" was born.
