Mazinkaiser

Mazinkaiser is the second mech piloted by Koji Kabuto, and is a Super Robot that is introduced in the first season of The Knights of the Multiverse before being completed and entering the field in Season 2. While Mazinger Z was described as "becoming either a God or Devil", Kaiser has been described as "being able to surpass a God and beat the Devil".

Season 1
Mazinkaiser's origins are actually pretty simple, and rather sweet: fearing that her adoptive father's legendary Super Robot might not last him much longer, Emily sought to try and design a new Mazinger for him. Unfortunately, she was having some trouble, so some of the other Knights decided to throw in their own suggestions, such as Amity proposing the simple idea of bulking it up and increasing its strength, Catra putting forward the idea of having swords come out of its shoulders like the Getter Robo's Tomahawks, Usagi recommending the forearms being given spirals like a drill to give it an extra, well, punch, Tom giving it devil horns 'cause it looks cool & he thought it might help emphasis the "God or Devil" thing he heard Koji talk about. Ayako even advocates adding a spare, super strong sword in the center of the chest, but Lapis pointed out how that would be sort of redundant with the shoulder swords.

Season 2
Mazinkaiser was put into production during the time between the first and second seasons, using spare parts from some of L.O.V.E.M.U.F.F.I.N.'s Super Robots.

Abilities & Weapons
Stronger form of the Rust Hurricane, with three high-powered tornadoes firing from Kaiser's mouth grill. A much more powerful version of Z's Photon Beam. Similar to the standard Rocket Punch, expect the spirals on Kaiser's arms spiral upon activation and launch, and is able to fire at a much faster rate and deliver much more punch. Inspired by Getter 2 and Liger's Getter Drills, Kaiser activates the spirals on its forearms and charge through an opponent at full speed. Can either do this one-handed or two-handed, and can even punch through two opponents with two hands. Mazinkaiser launches a powerful missile from its torso area. Kaiser is able to pull two swords out of it's shoulders. An enormous sword emerges from Mazinkaiser's chest emblem. A much stronger Breast Fire attack, with it able to cover a much larger radius and dealing a much greater amount of damage than the original.

Kaiser Pilder
Like the Mazingers before it, Mazinkaiser's cockpit is located in a separate vehicle which functions as a jet fighter. It is armed with a laser beam in the tip of the nosecone.

However, unlike the original Pilder, when this Pilder combines with Kaiser, the cockpit reconfigures itself into a control system based off of the same one used by Raideen and Daimos, one that allows Kaiser to follow all of Koji's movements.
