The second, more advanced class of monsters deployed by CRIME following the arrival of Big One. These Invader Robots appear from Episodes 23-35.

The first of the Invader Robots, and notably the first to be attacked by Big One. Her objective was to plant transmitters on ISSIS buildings to coordinate aerial strikes by Crimer foot soldiers.

She features a blocky, computer-component face framed by long brown hair, and wears a white trench coat. Her abilities include disguising herself as a normal human woman, phasing through solid walls, and using weaponized violin music.
Episode 23

Ordered by CRIME to take children hostage in order to trap the J.A.K.Q. team. He accomplishes this by playing a hypnotic horn, luring them away much like the Pied Piper.

He features a massive cranium topped with an oversized top hat that perfectly fits his head.
Episode 24

A fly-themed Invader Robot who attempted to ambush the individual J.A.K.Q. members while their guard was down, intending to lock them inside a secure cell.

His primary ability is firing a beam from his sword that generates a massive sinkhole in any patch of soil.
Episode 25

The captain of a spectral ghost ship seen flying through the skies over Tokyo. His design is an intentional visual homage to the ghost captain from Shotaro Ishinomori's 1969 animated film, Flying Phantom Ship.
Episode 26

A ruthless Invader Robot who captured innocent citizens alongside a troop of Crimers to force them into a concentration camp.

He resembles a humanoid crocodile wearing a heavily stylized Nazi officer uniform, complete with insignia armbands. He and his Crimer subordinates even march and salute in a fascist manner.
Episode 27

An octopus-themed dark priest capable of shrinking himself down to hide within a small crystal ball.

He can also use this shrinking power offensively to reduce the size of other living creatures.
Episode 28

A mantis-themed Invader Robot revived by Iron Claw through a ritual powered by telekinetic waves. Chief Mantis is directly linked to Iron Claw's power, making him extremely difficult for J.A.K.Q. to defeat through normal attacks.

Armed with an axe and supported by CRIME's Apache Army, he attacks ISSIS personnel and helps carry out a bombing assault against the ISSIS base. His connection to Iron Claw forces Big One to investigate and outwit Crime's leader before the team can overcome him.
Episode 29

A cobra-themed Invader Robot deployed as a CRIME assassin. He first appears during a trap at a secret weapons factory, drawing J.A.K.Q. into an ambush before launching a vicious counterattack.

Great Priest Cobra attacks with thrown cobras, fires darts from the cobra mounted on his head, and uses a constricting cobra arm to bind his enemies. His scheme centers on developing a deadlier poison capable of defeating J.A.K.Q.
Episode 30

An orca-themed Invader Robot sent by Iron Claw as part of a spy operation. Rather than relying only on brute force, Shachira Khan's mission involves infiltrating society and creating a spy so well-hidden that J.A.K.Q. cannot easily expose or attack him.

His episode focuses on covert surveillance, deception, and the danger of CRIME turning an ordinary civilian setting into part of its intelligence network.
Episode 31

A chameleon-themed Invader Robot who uses deception and impersonation to place Big One in danger. His scheme centers on creating confusion over which Sokichi Banba is real, exploiting trust and identity as weapons against J.A.K.Q.

After masquerading through false identities, he is eventually exposed when the real Banba outmaneuvers him. Once his disguise is broken, Dia Jack and Clover King take aim at him, turning the trap back against CRIME.
Episode 32

A buffalo-themed Invader Robot who launches an all-out attempt to destroy J.A.K.Q. His operation includes CRIME's deadly "cooking class" scheme, poison-based tactics, and Crimer suicide bombers sent to overwhelm the team.

Seeking to regain his honor after failure, Admiral Buffalo personally battles J.A.K.Q. but is ultimately destroyed by the Big Bomber.
Episode 33

A powerful super cyborg sent by Shine to replace Iron Claw as commander of CRIME. Great King Icarus is assigned to help complete Operation Stardust, a catastrophic plan intended to move Earth closer to Planet Shine so it can be colonized.

Operating from Crime Fortress Island, Icarus detects J.A.K.Q. activity, orders the Sky Ace shot down, and later pursues Spade Ace and Heart Queen when they infiltrate the island. His presence marks the beginning of Shine's open attempt to seize control of CRIME from Iron Claw.
