(Takashi Oda's universe)
I COVET ALL THE WORLD!Moon[src]
"Moon" (月 Tsuki ) was a tree-like behemoth. Thornheart made the creature as part of Noah's Ark, a plan to allow "new life to be born in a new evolution." It is the final boss in House of the Dead: Scarlet Dawn.
Throughout the battle, Moon grows into an invulnerable, winged humanoid giant. It cannot be killed by gunfire; only damage to its weak point -- the glowing spot on its forehead -- will delay Moon's projectile and arm slam attacks.
Though Moon is a physically large boss, his small weak point (the red dot on his forehead) and his multi-staged, spontaneous battle makes for a challenge. Bringing down his health-bar over time will result in the creature slowly emerging from his slimy prison and eventually transforming into a great, winged beast. The phases range greatly in difficulty, as Moon's fight involves different methods of melee and projectile-based attacks. The player(s) must keep their aim on the creature's weak point while also being aware of the several dangers Moon will pose throughout the battle.
- Emerging as a head, Moon spits a volley of slime-like projectiles into the air. The camera pans upward as the projectiles rain down from the sky; they must be shot in order to avoid damage.
- Moon's right arm emerges, raising upward for a slam attack. Damaging the arm enough successfully ends the phase.
- Moon grabs the player(s), briefly holding them near his face for slamming them into the ground. Shooting the creature's weak point cancels the attack.
- After Moon's left arm and torso emerges, the creature will send a homing energy orb after the player. The orb will vanish if shot enough times.
- Moon sends a large number of creatures flying in the air, which must be shot before they land on the player.
- Moon climbs out of the liquid mess, revealing the rest of its body and legs. It then charges up an orb of energy and slams it to the ground, creating a small water cyclone moving at high speed. Shooting the tornado will cause it to dissipate. Moon will do this attack twice.
- Moon charges up its right arm to throw beams of energy, with two more appearing after every one beam destroyed. Shoot all the beams to avoid taking damage.
- After Moon sprouts wings, the player(s) run to the top of a tower. Moon will fling wing-like projectiles; shooting all of them prevents damage.
- Moon launches fireballs from its mouth in various directions, before ultimately sending a fireball directly at players. Shooting its weak point will cancel the attack. Moon will perform this attack twice.
- A cut-scene plays, where Ryan expresses frustration as Moon continues to grow. He grabs a metal rod and jumps from the tower at Moon's face. This is a quick time event where the player has one chance to shoot Moon's forehead; regardless of their success or failure, Ryan kills the creature.
- Moon is the third boss following Temperance and High Priestess to not be able to be defeated through normal means. In Moon's case, it is only defeated after Ryan caused lightning to strike Moon, killing it in the process. This also makes Moon the only final boss where special attacks are necessary for his defeat.
- Moon is the second boss following the World that continues to grow after being weakened.
- Moon is similar to Sun in The House of the Dead III. Both are plantlike bosses, the players orbit the bosses like how planets orbit the Sun and the Moon orbits the Earth, and both employ various hit points for the player to hit. Both also seem to have been created through the same means, with faces on Sun's trunk indicating that it may have been formed from the amalgamated biomass of creatures like Moon.
- This is the first and the only boss in the series where the player can beat it without doing anything, though this will require a lot of continues. This is also the first boss in the series whose entire fight is scripted, meaning that regardless of how much health is depleted from the boss's health bar, the outcome of the fight will be the same.
- Moon is the only final boss in the series that does not appear to embody a specific, primal element of nature.
- Both Moon and High Priestess are the only bosses in the main series to not possess Type numbers.
