Collapsing Star Roaring Cannon

==Information==
Boros uses this ultimate attack against Saitama in their finishing final fight when Saitama returns from the moon.
==Description ==
A powerful energy attack capable of destroying a planet(s) and a Star, it uses nearly all of Boros energy and he even used his life force in the process to increase it's destructive capabilities.
== Limitations==
This attack has left Boros dead from overusing it and like Meteoric Burst it might have helped in straining his capabilities fully.
