Mighty Action X (マイティアクションX Maiti Akushon Ekkusu) is a 2D action-platformer video game created by Genm Corp. It is also served as the basis for the Mighty Action X Gashat and well as the two prototypes.

Game Description

Mighty faces off against Count Salty.

Mighty Action X is a 2D action-platformer game starring a cartoon character named Mighty who uses power-ups to defeat his enemies while traversing through a city landscape with one of the bosses being a villain named Count Salty.


Its concept was envisioned by future Genm Corp. CEO Kuroto Dan as early as 2000. Engineered History! According to Kuroto, the game took 5 years to develop as it was delayed from its intended release in 2011. Many Genm fans waited for its release and gathered at its launch party to play the first working demo of the game, only for the Salty Bugster to ruin the event. I'm a Kamen Rider!

It is later revealed by Kuroto that the development delay of the game was caused by Zero Day, as the prototype of the game along with the other 9 games glitched and created a bug which evolved into the Bugster Virus. It took years to completely debug the first four games and get them and the Rider Gashats their data is based off of working. An Operation Called Dash!

Mighty Action C

The disk that was sent to Emu.

The Mighty Action game series was already in development since at least the year 2000, when a young Kuroto Dan sent a game still in development known as Mighty Action C (マイティアクションC Maiti Akushon Shī) to a young Emu Hojo. This version of the game contained the earliest version of the Bugster virus, thus causing Emu to be infected, becoming patient zero of the Bugster virus while giving birth to a being who would later become known as Parado (Kamen Rider Para-DX), a powerful Bugster who also possesses Emu's High Gaming IQ.

Salty Bugster is a malicious Bugster who takes his likeness as he called himself as Count Salty, having been created from the data of Mighty Action X.

Mighty Action X Gashat

Mighty Action X Gashat

When the Gashat is activated, it reformats the battlefield into a Game Area and spawns brick-like boxes around the area, grounded or floating. These boxes can be used as solid platforms for jumping, or be broken for Energy Items. Ex-Aid has demonstrated the ability to make these boxes appear from thin air when he needs to jump higher, but it is unknown if these boxes were already hidden there, or spawned by Ex-Aid himself.

When activated, this Gashat reformats the battlefield into a Game Area and able to spawn brick-like boxes around the area. This Gashat is currently in possession of Kamen Rider Genm. When used in VR, the screen become black and white. According to Hiiro, Proto Mighty Action X was the origin of the Bugsters.

According to Dan and Parado, the usage of the Proto Mighty Action X Gashat and the other prototype Gashats have a side effect that makes the user more insane, losing their morals, and also damaging their bodies with prolonged usage. Taiga suffers from unknown body damage from Zero Day, causing his hair to grey while Dan slowly loses his sanity with his body deteioriating to the point where the latter devised a plan to give him an undying body.

Proto Mighty Action X Origin Gashat

Proto Mighty Action X Origin Gashat

This Gashat was the first Kuroto ever created, and is the alpha version of the original purple Proto Mighty Action X Gashat. It possesses the "Continue" function, allowing its user the ability to revive after death up to 99 times.

When activated, this Gashat generates a unique Game Area which is capable of nullifying most, if not all, of a Bugster's powers.

The Gashat was used as a failsafe for Kuroto Dan should he ever be killed, acting as his "save data".

This mass-produced version of the Mighty Action X Gashat is generally sold by Genm Corp. and is functioned to play the 2D action game "Mighty Action X". 

It is known by gamers as "a legendary game that has been discontinued", and its completion was announced in 2016, which has been developed for more than five years of production announcement.

Like its Gashatrophy counterpart, it doesn't possess a handle and a shorter RG Circuit Board, though longer than the Gashatrophy's.

Sota Suyama would mistake this Gashat for the one that would become Emu Hojo's personal Gashat.

Real World

Mighty Action X is a Japanese video game developed by Seventh Chord and Bandai Namco Entertainment exclusively for the Nintendo 3DS. It was created as a means to promote Kamen Rider Ex-Aid, and is available only through a download code from purchasing All Kamen Rider: Rider Revolution.


Players must traverse across the stage, defeating enemies and utilizing power ups until they reach the end. There are 4 stages in the game plus one bonus stage where players can become the black Mighty from the fictional prototype game.

Power ups

  • Recover: Restores health
  • Speeding-Up: Boosts speed and agility
  • Muscular: Increases the power of attacks and fills the special gauge.
  • Confusion: A detrimental power up, Mighty becomes confused and the controls work differently.
  • Giant: A rare power up that allows Mighty to temporarily grow to giant size and destroy all the enemies on the screen in one attack.


  • B button to jump
  • A, B+A or B and Hold A and a direction on the joystick to do a Roll Attack. The Roll Attack uses up 1 of the collectible gummies as fuel every time it is used or drains them slowly if used for gliding. If the player has none, the ability cannot be used.
  • Y to attack
  • B and Y to do a Jump Attack
  • B and R Button to the Mighty Kick attack. Costs five gummies per use.[1]


  • Mighty Action X is based on classic 2D Side-scrolling Platformer adventure games such as Super Mario Brothers, Mega Man, and Sonic the Hedgehog. Design wise he is very similar to Kirby and Ristar. Since the game's genre is a 2D side-scrolling platformer adventure, the game title is named after Mega Man X. Ironically on the way bosses are defeated is also a reference to Mega Man X boss fight defeats.

Mighty Parado X

  • In an event in Kamen Rider Battle: Ganbarizing, Parado has turned the game into Mighty Parado X.
  • Proto Mighty Action X is the only Proto Gashat that is not black in general, but dark purple instead.
    • It is also the only Proto Gashat to have a colored picture, instead of a black and white picture like the others. The reason for these differences is to show that Proto Mighty Action X was a modified Gashat.
  • The Mighty Action X Gashat and the Proto Mighty Action X Gashat were once combined into a single Mighty Brothers XX Gashat and used to access Kamen Rider Ex-Aid Double Action Gamer Level XX. Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider
  • Like many older classic games, the console versions of Mighty Action X are possible ports of the Arcade version. The Paradox of Defeating M
