Great Samuraider

The Great Samuraider (グレートサムライダー) is signature Super Robot piloted by Jin Yuugami, better known by his superhero alias, the Goddamn Samurai. Designated as the Anti-Demon Gestalt Mechanical Combat Unit Zero (対魔戦闘合機零式) and authorized for self-defense by the Japanese Self-Defense Force, it is the combination of the five Samurai Machines: the Samurai Jet, Samurai Mobile, Samurai Tank, Submurai and Samurailer.

Abilites
Its powers and abilities are come from the electricity running together from the robot's five separate components combined into a powerful surge of energy into itself, allowing the Great Samuraider to perform excellent feats in kaiju combat.

Weapons
The Great Samuraider's main weapon is a larger version of the Goddamn Samurai's katana-like sword Kokuzantou (黒斬刀). It can utilize liquid memory metal to allow the blade to grow into a large broadsword for heavier combat.

The Samuraider's strongest weapon is the Bushin Souten Ihou (武神双天移砲), a gigantic phase-transition cannon that is launched from the Samurai Cave to be used by the mecha.

Attacks

 * Kokuzantou Lightning Speed (黒斬刀・電光石火) - The Goddamn Samurai uses the Kokuzantou in its base form with a swift swipe in the air to create a strong enough wind to cut the enemy.
 * Kokuzantou Colossal Wheel (黒斬刀・大車輪) - The Samuraider uses the liquid memory metal to enlarge the Kokuzantou into a larger kukri-like blade. It then throw it as if it were a boomerang.
 * Kokuzantou Fang Crush (黒斬刀・牙壊) - Using the Kokuzantou in its base form, the Samurai rushes past an opponent and slashes them with one swift stroke.
 * Kokuzantou Thunderclap Slash (黒斬刀・雷光斬り) - The Samurai enlarges the Kokuzantou into a large broadsword. It then uses it to perform a giant vertical strike from below the opponent and then performing a swift horizontal strike so fast that it is almost invisible to the human eye. This attack is also called the Kokuzantou Thunderstorm (黒斬刀・疾風迅雷).
 * Kokuzantou Storm and Stress (黒斬刀・疾風怒濤) - Great Samuraider draws its Kokuzantou, lifting then slamming it onto the ground right before going airborne. While airborne, the Samurai makes a complete stop while swinging its blade in a circular motion, followed by an overhead blade-draw. After that, Samuraider initiates a diagonal diving charge, accompanied with its boosters flaring up as it dives. A hard, head blow strikes the enemy, and Samuraider ends it with a "twist-and-cut", causing the ground to break around it.
 * Kokuzantou Cleave of Clouds (黒斬刀・雲燿の太刀) - The Great Samuraider enlarges the Kokuzantou to such a point that it's almost too large for the arms to even handle. The Samurai lifts the weapon high above the head of the Samuraider and proceeds to take to the sky. The Samuraider drops down with a single bisecting slash as a finishing attack.
 * Bushin Souten Ihou - Hurricane Vanquishing Firepower (武神双天移砲・竜巻逸騎砲閃) - The Samurai summons the massive phase-transition cannon, launching from the Samurai Cave towards the Great Samuraider's location and arms it onto itself. The Samurai then removes all safety to activate the Samuraider's Full Charge and imbue its energies on the active Souten Ihou. After charging at full power, the mecha fires the cannon at its opponents, releasing an incredibly massive wave of blue energy at it and obliterating the enemies in a fell swoop.
 * One-Strike Combined Finisher - Twin Wave (一撃合体必殺・武神双天波) - The combination attack of Gamera and the Great Samuraider, the turtle kaiju opens its armored chest to prepare its finisher while the mecha summons the Bushin Souten Ihou. Gamera and Samuraider unleash the Mana Volcanic Release and the Hurricane Vanquishing Firepower respectively, with the streams of red firepower and blue energy merge into a powerful helix, speeding directing at the opponent and utterly decimating it in a bright and massive multi-megaton explosion that comes afterwards.

Trivia

 * In the English-dubbed versions of The Goddamn Samurai and Gamera vs. the Goddamn Samurai as seen on Netflix, the mecha throughout the story of both films is referred to as "Super Samuraider" instead of Great Samuraider.
