The enemies found in the game are called machine soldiers and are robots built by the Naga Empire, often modeled after sea creatures. This page lists all the machine soldiers that appear in the game.
Names, when given, come from either the art book, or an official video. "Armor" represents the number of boost attacks necessary to destroy the enemy in the Wii version of the game, when not powered up. The list of mech pieces (from the Wii U/3DS version) is not necessarily exhaustive.

This yellow boxfish is most common and weakest enemy. It just flies around without attempting to attack the player.

Mech pieces:

(Red Fish)[]
It is similar to Parolilo, but will periodically extend spikes all over his body then retract them. While the spikes are out, the enemy is invulnerable and will damage Rodea if he tries to attack.
Armor: 1
Mech pieces:
- Iron Screw
- Iron Scrap
- Junk Plate

Chandori[]
An enemy in 8 parts. It flies around and will launch missiles at Rodea. Each part can be attacked individually. If the head is destroyed, all the parts attached to it get destroyed as well. If a middle part is destroyed, the parts that are no longer attached to the head will become a separate enemy with its own head, that will also shoot missiles. However, only the original head will give a mech piece when destroyed.
Armor: 2 per part

- 3 per engine in Chapter 4
- 4 per engine in Chapter 8
- 4 for the turret
Mech pieces:
- Steel Wire

Gamentia[]

Armor: 1
Mech pieces:
- Copper Wire
- Chrome Shaft
- Aluminum Shaft
- Steel Wire
Melimbo[]
A flying enemy consisting of a core and 8 pieces that form a circle around it. It's apparently modeled after an acorn barnacle. It warps around, making it very difficult to hit until it stops to shoot a purple energy circle.
Armor: 2
Mech pieces:
- Titanium Shaft
- Magnetic Lens
- X-Ray Lens
Angania[]
A large and particularly tall crab; its name is spelled "Anganya" in the art book. It stays in one place, but if Rodea gets too close, it will shoot energy projectiles from the four turrets on its back. The player can also be damaged by its electric claws. Its weak point is under its belly.
Armor: 5
Mech pieces:
- Old processor
- Giant Screw
- Diamond Scrap
Abirage[]
It's a floating jellyfish robot that stays in one place and regularly spins for a couple seconds. It is invulnerable while it spins; if Rodea tries to attack during that time, in the Wii version, he will be pushed back without damage; in the Wii U/3DS version, he will take damage.
Armor: 2
Mech pieces:
- Iron Cog
- Chrome Cog
- Cobalt Gear
- Titanium Cog
Doroll[]
A robot that looks like a centipede (it's apparently supposed to be a mantis shrimp) and lives in the sand. It regularly curls itself and rolls towards Rodea to crush him; it is invulnerable during that time. After some time, it will dive back into the sand, then it will emerge at its original position and stay out in the open for a few seconds.
Armor: 4
Mech pieces:
- X-Ray Lens
- Carbon Shaft
- Mysterious Parts
Okala[]
A round enemy with a shield. It keeps floating in one place, without moving or attacking. At first, the shield is always facing the player, preventing him from hitting the enemy, but when Rodea attacks the shield, it stays immobile for a few seconds, which makes it possible to attack from a different angle.
Armor: 2
Mech pieces:
- Lens
- Reinforced Lens
- SLA
Alalage[]
It looks like a small jellyfish. It flies in a vertical circle and periodically generates an electric sphere around itself.

(Searchlight)[]
A small flying robot with a searchlight. When it detects Rodea, it rings an alarm and shoots energy projectiles.
Armor: 2
Mech pieces:
- Iron Wire
- Reinforced Lens
- SLA
Yadokapila[]
A massive armored crab. It can bury itself under the snow, and will only come out when the player approaches. It attacks by hurling itself at Rodea, and can also breathe cold air that freezes Rodea's tail, weighing him down.
Armor: 6
Mech pieces:
- Adamantium Fiber
- Ancient Cog
- Ancient Parts
Helio[]
It is similar to Okala, but is less round and has 6 shields forming a ring. Like Okala, it doesn't move and Rodea must attack the shields to immobilize them before attacking from a different angle.
Armor: 2
Mech pieces:
- SLA
- Magnetic Lens
(Sea Urchin)[]
It is made of two half shells covered with spikes, and a core that is its weak point. It flies around and, when the player approaches, it closes its shell and spins towards him. After a few seconds, it opens again for a short time. It is necessary to attack with the right angle (not too high or too low) to avoid hitting the spikes.
Armor: 1
Mech pieces:
- Titanium Cog
- Cobalt Gear
(Octopus)[]
It isn't a regular enemy; it flies upwards when attacked with the Machine Gun Gear several times, which allows Rodea to reach high places. When it reaches a certain altitude, it explodes and another one appears. In the Wii version, if Rodea shoots it with the Machine Gun Gear but not enough to make it fly, it will ripost by shooting a purple projectile.
Lalita[]
It appears exclusively in Chapter 14. One will appear after destroying the first watchtower, a second one will appear after destroying the second watchtower, and they will both disappear after destroying the last watchtower.
It is completely invulnerable. It flies in a circle around Rodea when he's on the ground, and attempts to tackle him if he flies.
Kamyu[]
It can't be destroyed. Its neck stretches when the head is attacked. In the Wii version, this is used to reach places that are otherwise too far away; in the Wii U/3DS version, the head is used to push switches that are behind electric walls.
