Grendizer

Grendizer is the titular robot of UFO Robo Grendizer and is a super robot featured in Knights of the Multiverse Season 1. It was created by Dr. B of L.O.S.R. to resemble a stereotypical flying saucer in a scheme to create the illusion of an alien invasion (which, by this time on Earth Prime, isn't really that much of a surprise anymore).. His design was also based off of the Mazinger robots.

Personality
Compared to his more... unique brethren, Grendizer is a much more serious-minded bot, only focusing on achieving his mission of battling the Knights. He also seemingly tries to make himself out as being a savior of some kind, being programmed by his masters to think of himself as a hero and the Knights as dastardly villains.

Armaments
Eye lasers
 * Dizer Beam

Three beams of concentrated energy fired from the back of one of Grendizer's hands, which can also be fired simultaneously from both hands, allowing six beams of fire at once.
 * Hand Beam

Based off of the Mazingers' Rocket Punch, Grendizer flips the blades mounted on it's wrists forward as the forearms begin to spin in place rapidly, where they are then fired with tremendous force, essentially turning the forearms into flying drills, that fly at speeds of Mach 5 and can achieve 4000 RPM.
 * Screw Crusher Punch

Crescent-shaped blades mounted in Grendizer's shoulders eject either together or one at a time, each deploying a shaft to be utilized as Single Harkens. When both are simultaneously ejected, they can combine at the base of the shafts to form a single bladed staff, the Double Harken. In either form, the Harken can also be thrown at enemies like a javelin.
 * Harkens

In tight situations, Grendizer can launch the Harken blades from its shoulders with incredible force as a projectile. When ejected, they can also be wielded and thrown like regular boomerangs.
 * Shoulder Boomerang

Based off of Mazinger's Breast Fire, a rainbow-colored beam of concentrated, anti-gravity energy fires from the red crest on Grendizer's torso that is capable of launching foes upwards by thousands of feet, or crushing them instantly through the intense forces of anti-gravity.
 * Hanjūryoku (Anti-Gravity) Storm

Based off of Great Mazinger's Thunder Break, Grendizer can release a burst of electric energy from the horns on its head. Grendizer can unleash up to 60,000 degrees worth of volts for up to 10 hours continuously.
 * Space Thunder

Spazer
Similar in structure to the Mazinger Robots' Scranders, the Spazer is a flying saucer-shaped vehicle which link up to Grendizer an advantage in battle, including several additional weapons.

A drill-shaped missile fired from the discs on the Spazer's wings. The discs attached to the Spazer's wings fly off and sprout blades, turning them into deadly slashing projectiles.
 * Spin Drill
 * Spin Saucer

The Spazer can fire a blast of highly corrosive liquid from ports above Grendizer's docking port.
 * Melt Shower

The Spazer can emit a purple fog which scrambles radar.
 * Anti-Radar Mist
