Mechas
The titular mecha of the series, though only called Kaiser by the characters until the end of the series, when Yuuki refers to it by its full name. Unlike the Mazinkaiser featured in the first OVA series, manga, and in video games, this version of Mazinkaiser has a completely different design, sporting a more demonic look. One of the biggest changes is the Kaiser Pilder, the aircraft used to dock onto the crown of Mazinkaiser to control it. It has been renamed as the Skull Pilder and redesigned to resemble more of a human skull hence its name. The Skull Pilder also requires two pilots to control it, unlike the Kaiser Pilder where it is controlled by a single pilot. Another notable change is the eyelids having a blue color as opposed to yellow from past Mazingers. A skull in the center of Mazinkaizer SKL's chest is used in place of the "Z" symbol from the original Mazinkaiser.
The weapons for Mazinkaizer SKL are also different from that of the original Mazinkaiser. This incarnation of Mazinkaizer is equipped with a weapon known as the Ganzantou, a gigantic sword attached to its back. The sword's handle can be extended so it can be used as a pole weapon. The spikes extending at the other side of the Ganzantou's blade is designed to tear apart the innards of its target, as seen in the promotional images.
Another weapon unique to Mazinkaizer SKL are the Breast Triggers. Attached to Mazinkaizer SKL's chest area, they are a pair of handguns SKL can use to shoot its enemies from mid-range. Blades are also attached to the nozzle and beneath the handle of each handgun, allowing the Mazinkaizer SKL to slash at enemies up close. They can also be merged into a battle axe type weapon akin to the Getter Tomahawk and used as a melee weapon. When the Breast Triggers are not in use, they are holstered to the chest, which forms a resemblance of Devilman's face.
When combined with the Wingle's Scrander the Wing Cross, SKL's limiter is released, allowing it to fight at full power, changing its eye color from blue to yellow, as well as unlocking a new set of weapons which are variations of those from past Mazingers. The Tornado Crusher Punch is SKL's version of the Turbo Smasher Punch, with the difference being that Ken Kaido is able to guide them to their target after they are deployed. The Breast Triggers fire laser beams as opposed to solid rounds. The Rust Stream is SKL's version of the Rust Tornado from Mazinkaiser. The Thor Hammer Breaker allows SKL to shoot a huge bolt of lightning towards its target from the Ganzantou, similar to Great Mazinger's Thunder Break. Finally, the Inferno Blaster is SKL's most powerful attack, acting similar to the Fire Blaster from Mazinkaiser.
The female support robot for Mazinkaizer SKL. The Wingle's design incorporates the female mechas used in the Mazinger franchise (Aphrodite A, Venus A & Minerva X) as well as elements of Devil Lady. It is given black and light purple colors with some gold trimmings. The bat-like wings attached to the rear of the Wingle's head act as a Scrander part for SKL (called the Wing Cross), allowing the latter flight capabilities and unlocking its full potential. Like SKL, the Wingle also has a detachable cockpit on its head called the Lady Falcon, which is piloted by Tsubasa in the anime and Scarlet in the manga. Its weapons include a pair of detachable blades that can be mounted on the arms or the legs and used as boomerang-type projectiles, as well as a flail stored in the left breast.
Kiba's personal mecha. It is a green colored unit with horns shaped like a crescent moon on its head and shoulders, almost resembling a samurai warrior. Like Mazinkaizer SKL, it is a very agile unit despite its heavily armored appearance. It rides a vehicle made of Caterpillar tracks for faster transport and is equipped with two large cannons on the front, although they were never used in the anime.
A robot hidden within Garan's fortress, it is a secret weapon developed by the WSO and serves as one-half of the Gravity Curtain, having been powered by the same source – the Graviton Reactor. The reactor grants the Iron Kaiser a near-limitless supply of energy as well as incredible speed and power. The overall armored design of the Iron Kaiser is loosely based on Shuten Doji, a character from Go Nagai's manga of the same name and sports a red and gray metallic color. It also has a Pilder attached to the robot's cranium, able to transform itself into a discus to slice off its target, similar to some of the enemy mechas found in Grendizer. Its weapons include its own version of the Turbo Smasher Punch (Smasher Punch) and Rust Tornado (Iron Tornado), a double-bladed spear, a Gatling gun, missile launchers, and shoulder blasters. The Iron Kaiser is piloted by Kiba in the final battle against SKL.
The personal mecha of Garan. It is a large robot with the color schemes of white, gold and gray. Three horns are attached to its head, with spikes on the shoulder and knee caps and claws for the feet.
A mass-produced female combat mecha of the Hachiryoukaku. It is equipped with Beam Weapons for combat, as well as producing a barrier needed to protect the Hachiryoukaku's home base from enemy attacks. The Psycho Gears piloted by Hurricane, Fancy, Misty and Flash are unique in that they are of different design styles.
Mass-produced units of Kiba's army. The unit is based on Garada K7, one of the enemy units of Mazinger Z, and carries its signature giant sickles attached to its head. A mono-eyed mechanized head is used in place of a skull from the original Garada K7 and is given color schemes of purple and light green.
Also a mass-produced unit of Kiba's army. This unit is based on the enemy mecha Doublas M2, also from Mazinger Z. It retains the dual head design and spikes on the legs. Changes made were to the lizard-like heads being more mechanical, sporting three sets of scopes and a mounting weapon at its mouth. It is given a more desert-style color scheme and a large Gatling gun is attached to the right hand.
Garan's personal robot army. This unit is based on KingDan X10, also from Mazinger Z. They are muscular robots with bull-like horns attached to its head. They have various color schemes and also possess a variety of combat weapons such as lances, glaives, flails and archery-type weapons.
Appearing only in the novel version, the Mazin Brothers are mass-produced versions of Mazinger Z. While it shares the same appearance as the original, it does not possess the same set of weapons. Instead, Mazin Brothers are either equipped with a set of missile launchers or a large Rust Hurricane Backpack as weapons.
Appearing only in the novel version. This Mazinger Z appears severely damaged as it leads an army of mass-produced versions of itself called the Mazin Brothers in a losing battle against an enemy army. Despite its condition and the grim situation, Mazinger Z continues to battle until the arrival of Mazinkaizer SKL who provides the much needed reinforcement. The pilot of Mazinger Z is not named.
