The Jupiter King is the boss of Mission 3 from Metal Slug 3.

Information

The Jupiter King is a giant defensive robot created by the Rebel Army to guard their secret factory. It is heavily armored to protect the nuclear reactor inside the robot's body. The lightly-armored head (which resembles a toy robot's head) serves as the robot's weak point.

Its armaments consist of a missile pod on its left arm that allows the robot to fire several homing missiles. Its prehensile right arm is equipped with a large claw-like manipulator that can be changed to destroy the surface in front of it. The robot's eyes are also capable of emitting lasers to attack enemies. The Jupiter King also has a "belly button" that can create a large missile, from which the robot grabs and plunges into the surface.

Details

The battle with Jupiter King takes place in an infinite stretch of room with a pool of molten metal underneath the surface. In battle, the Jupiter King continually moves to the right, while it attacks by firing a series of homing missiles, firing a delayed but deadly laser from its eyes, and change its pincer claw to destroy the surface. After taking a certain amount of damage, the Jupiter King will use a new attack; launching a large missile from its "belly button" and grabbing it with its pincer claw, then crashing it into the surface, destroying a portion of it and producing multiple fireballs to fly over the player.

The player can earn weapons by shooting at the flashing homing missiles.

In Other Games

Metal Slug Defense

The Jupiter King is a playable unit available for purchase once stage 10 of World 2 is beaten. Despite the Jupiter King having a high AP cost (at 900 AP), its only attack is firing lasers with a long delay. A mini version with the same attack pattern is available.

To compensate with its reduced attack kit, a variant called the Jupiter King MK II was introduced. It has the same AP cost and cooldown time as the original one but its stats are way better than those of the standard Jupiter King (i.e. Jupiter King has 15,000 HP at level 30 with Jupiter King MK II having 40,000). It attacks by dropping missiles.

Appears in Metal Slug Defense and Metal Slug Attack.

Jupiter Queen: Another variant the Jupiter King, this time made by the Ptolemaic Army. It is colored in pink and silver/white. It also uses its eye laser for its normal attack and its Pyro-Arm for its special attack. Appears in Metal Slug Attack.
Golden Jupiter: As it name implies, it is a golden version of Jupiter King. It uses the pyro arm and the laser. Now both attacks produces deadly fireballs to damage the enemies, and if it is attacking, it won't be destroyed until the animation ends. Unlike it's predecessors, the "lightning" created before using the laser can also damage units it touches.

It has a much more robotic features than its predecessors, hence being true to its name. It is piloted by both Donald Morden and Allen O'Neil and attacks with its powerful stomp and fists.
