Huge Heart is the boss of stage 4 in Gradius V. It is the only organic boss in the game. The Huge Heart itself does not attack. The body around it uses defense mechanisms.
The tubes on the top and bottom of the Huge Heart are the source of its attacks. The Huge Heart can attack by releasing rotating bone pillars that fire lightning bolts from the sides, releasing huge tusks at the player's ship (like the famous "teeth" from the first stage of Salamander), releasing a flaming snake-like creature, shooting large lasers from several eyes, and creating small volcano like openings that spew green mucous. The Huge Heart is protected by a force field with a weak spot that circles around the force field that must be destroyed in order for the Vic Viper to shoot the heart itself. The force field regenerates after several seconds.
- Huge Heart has probably the most gruesome death sequence of all the bosses in Gradius so far. It begins pulsating rapidly while streams of green blood gush out of it in five sections. It then proceeds to explode into a violent, framerate dropping, Michael Bay-esque explosion like every other boss in the game.
