A former Star Guardian and Guest's partner Metal Cardbot. He has a kind way of speaking. Skill Description: Alpha Bolt Cannon | When fired, a wolf's howl sounds and energy forms into the shape of a wolf's head, unleashing a powerful electric laser bombardment as if a wolf were breathing fire. The barrel can be deployed in one stage for lower-intensity fire. Thunder Howl Smash | He jumps high into the sky, forms a wolf-head aura from his Howl Gauntlet, and throws a punch while the wolf head simultaneously bites the opponent fiercely.

Guest's Metal Cardbot. He speaks with a serious tone. Befitting the name Heavy Iron, his combat power is substantial. Skill Description: Heavy Dragon Breath | He swallows energy compressed into a sphere with the Iron Dragon and fires it as a beam; during casting, a dragon's silhouette surrounds his entire body. Iron Cannon | Fires a powerful beam from the Iron Armor. Even just being near the beam causes ordinary Metal Cardbots to have their Weapon Cards forcibly detached and leaves them covered in wounds.

Guest's Metal Cardbot. He tends to act a bit tough and showy. He calls Blue Cop a 'young pup' and refers to Heavy Iron W as his 'brother'. Skill Description: Outrage Horn | An attack skill where he gathers all his energy into the Rhino Hide's horn and charges. A rhinoceros-head aura appears over the Rhino Hide during execution, and he can negate his weakness to heat attacks while the skill is active. Ground Fury | An attack skill where he gathers energy in the Terra Crusher and strikes down, devastating the target or the surrounding ground in a wide area. Its power shown in the story exceeds Outrage Horn, but since it is an area-of-effect skill, it is difficult to use when he needs to worry about affecting nearby allies.

A former Star Guardian and Guest's Metal Cardbot. His real name is Saber Knight. He has a serious but kind way of speaking. He has Elephanted Mode, Giraffed Mode, and Zebrad Mode. Skill Description: Tri-Specter | A skill that summons the silhouettes of an elephant, a giraffe, and a zebra simultaneously to perform a linked attack. Missile Pod | 12-round missile pods equipped on both wrists. A weapon he has possessed since his days as Saber Knight, used for suppression and covering fire.

The final boss. Strong enough to destroy Planet Machina. He has Behemoth Form, Leviathan Form, and Wyvern Form. Skill Description (Only names listed due to character limit): Emotion Extraction and Absorption. Becomes stronger when Vehicles 1, 2, 3, and 4 combine.
