Game Description

KREA Salty Bugster in game

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!

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.

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.

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.

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".
