Description
The Krion Conquest (known as Magical Kids Doropie in Japan) is a side-scrolling action/adventure game made by Vic Tokai in 1990 for the Famicom and NES and later ported to mobile phones in Japan. The game takes place in the then-futuristic year 1999 when the Krion (Akudama) Empire attacks Earth with an army of robots, and the only thing effective against them is magic. Thus, Doropie, a mercenary witch-for-hire, sets out to stop them.

The game very closely resembles the Mega Man classic series, as Doropie has the ability to use/change magical weapons as she wishes, and when doing so, her clothes change colors. Several of the enemies resemble those found in the MM series, such as the Mettools (spelled Mettuar in this game).
