Hokuto 100-Crackhammer

The Hokuto 100-Crackhammer is a new Keyblade that is set to appear in Superhero Keyblade Wars. It is shaped like a lightning bolt

Origin
The original idea was conceived by GokaiWhite when he watched the Fist of the North Star anime, to design a jackhammer that makes the same sound as the protagonist, Kenshiro, does when performing the Hokuto Hyakuretsu Ken (北斗百裂拳 Hundred Rending Fists), or a rapid-firing machine gun that makes the same sound when being fired. It was eventually decided that both those things would be fused into a new Keyblade for Sora to use in Superhero Keyblade Wars, and he would also be able to put on Kenshiro's outfit through Schemata Shift.
