DESCRIPTION

Gravestone, otherwise known as Project: Gravestone, born on an unknown date, is a large and cracked stone statue made to resemble Blue, given the mission to kill him in the case Tony wasn’t able to. He is the first and only secret boss in ULTRABLUE: PART ONE.

In the game, Gravestone’s domain Hotel Hell, is accessed from a secret entrance within Mansion Mayhem. And defeating the boss allows you to skip the first fight against Tony and unlocks the ability Sphere: Bomb. Within the lore and comics, Gravestone is a weapon created from spare traces of Blue’s DNA Tony had acquired, designed to match him in strength and act as a stall. When he is eventually defeated by Blue, Blue is able to absorb his remaining energy in the form of Sphere: Bomb.
