The primary antagonists of the series who plot to conquer Arachna. The Invectids are a race of humanoid insects that reside in the Invectid State. Members of the Invectid race include:
The Invectid Foot Soldiers are the foot soldiers of the Invectids. They come in different varieties and often accompany any member of the Big Four or any other field commanders. Some of these variations include:
Original Foot Soldiers - These are the lesser version of the Invectid Foot Soldiers. They are usually commanded by Buguese and Grasshop and even other high-ranked members of the Invectid Army.
Stags' Foot Soldiers - These come in two varieties. White foot soldiers are the most common variety. They use curved clubs/swords to combat their opponents. The second variety are tan and use throwing knives that resemble Stags' sword.
Mantid's Royal Guards - These soldiers only seem to serve within Castle Mantid. They seem to resemble ants.
Enhanced Invectid Warriors - Invectids made from science and the Oracle's power. They are very fast and strong. One was able to stand against the power of 2 Oracle Keys before being thrown back. They do not talk much.
Buzzrays
The Buzzrays are flying manta ray-like soldiers of the Invectids. They seem to only appear with Beerain.
Invectid machines
Giant metal insects used by the Invectids. Among those are:
Smashopper - A giant metal grasshopper-type Invectid machine that battles Hunter in episode 1 while Grasshop rides on him.
Praying Mantech - A giant metal mantis-type Invectid machine that Buguese rides on in his battle against Hunter and Corona near the memorial of King Arachna I. Praying Mantech opens up part of his armor when he uses his missile launcher causing a weak spot.
Billbug - A giant metal pill bug-type Invectid Machine that fought Magma and Brutus in the Forest of Bewilderment. It is indestructible when in its ball form. It was defeated by Magma.
Sphere-Beetle - An Invectid Machine that has three stages. The first form was little harmless balls called "sparkling orbs" which kids found in a crack. The second form is when the orbs fuse to create a light built Invectid. In this form it uses telekinesis to use the kids as a shield. The last form is created when the last unclaimed orbs fuse into the beetle to create a heavier built beetle. It still keeps its telekinesis but since it is so large it cannot use the human shield as effectively requiring a camouflage technique that rendered itself invisible.
Celpido - A giant metal centipede-type Invectid machine used by Buguese. Celpido caused sinkholes in a village to destroy it. Celpido is the first Invectid machine to have the power of speech. It also has feelings, which may mean he is organic.
Battle Beetle - A giant metal beetle-type Invectid machine used by Buguese when fighting the Spider Riders within Oracle's Shrine. This Battle Beetle has the ability to blind its enemies with a bright light when it opens its armor. This beetle has shown its mass strength as Lumen, Igneous, Corona, and Magma struggled to survive against it. Hunter defeated it in one shot using the Elektra Twist for the first time in the episode "A New Power." Another one was introduced in "Protectors of Life" and this one had laser cannons and the ability to regenerate damaged parts. Grasshop managed to uninstall the device that enabled this, allowing Hunter to finish the bot.
Cyber Cricket - A giant cricket-type Invectid machine that uses sound waves as its main attack. It was destroyed in the second battle by the combined force of Igneous and Magma after it attacked Hunter when he got in the way of its attack on Corona.
Battle Bug - A giant metal beetle-type Invectid machine used by Grasshop. In "Wages of War," Grasshop used it to capture an Invectid named Katy, but forgot to install the device that determined friend from foe, causing it to attack him. It is armed with a laser cannon and it gets more powerful the more Katy fears fighting. He told Hunter its weakness out of cowardice; slash off both antennae at exactly the same time or they will grow back. Hunter and Aqune defeated it together.
Iron Ant - A giant metal ant-type Invectid machine that Grasshop used after Hunter foiled his chase upon the Nuuman Page. It has powerful pincers and large contact lenses as ants can't see very well. Hunter almost lost his life fighting this Invectid machine solo.
Robo-Beetle - A giant beetle-type Invectid Mecca that is strong enough to survive the attack of 1 Oracle Key. It was destroyed when Hunter combined 2 Oracle Keys.
Golden Bore - A huge Invectid Mecha that produces an indestructible shield called Gold Rush and a powerful burst of energy called Gold Fever that defeats all enemies in the area. He doesn't like to be bossed around, and tends to call Grasshop "little bug". He really loves regurgitated grubs and sugar as his magic words were "Pretty please with sugar on top". His only weakness is that when he falls on his back he can't get up. He is the second Invectid battle machine that can talk.
Buzz-Warrior - One of Beerain's machines which she used in "Spies and Lies" to fight Hunter. She fought honorably, but still lost to Hunter even though he never used the Oracle Key. It's capable of creating high winds and fires stingers from its abdomen.
Dark Opal - An extremely powerful machine created by two Oracle Keys. It has laser beams in its eyes, mandibles that shoot a big energy sphere and the ability to absorb the Oracle Key's power. It is the first Invectid battle machine that can be piloted. It was most likely destroyed in the explosion seen in "Welcome Back".
Ark of Destiny - A boat created by Mantid. It was possibly used by Mantid to return to The Outer World as Mantid is actually a human wearing a mechanical suit. It is capable of firing energy beams. If destroyed, Mantid can just resurrect it.
