The Galactic Nova Nucleus (originally called the Heart of Nova) is the core of Nova. This boss appears in the game Kirby Super Star and its remake. It contains clusters of mechanical spheres that move up and down on electric bars surrounding Nova's actual heart. Damage can be avoided simply by dodging the spheres. Kirby simply has to shoot down the small energy spheres with the stars shot by Starship to damage Nova. However, Kirby has to be careful, as the towers can crush him against the sides of the screen. There are eight columns total, and Kirby can destroy the columns in any order he wishes, but there may be some prices to pay if he isn't careful.
