[2] Once upon a time there were two scientists, Dr. Little Emon (リトルイーモン) and Dr. Ivan Walnuts (イワンワルナッチ) (renamed to "Ermin" and "Warner" in an English fan translation), who worked together to create the world's most spectacular robots.
One day, Dr. Walnuts disappeared with the laboratory's seven military robots before appearing on TV to declare his intention to conquer the world.
Sukapon's first task was to defeat the seven other robots and allow Dr. Emon to reprogram back to their original selves.
After fighting each of their doppelgängers at Dr. Walnuts's castle, they finally face off against the most powerful robot, Hō'ō (ホウオウ, Hoh-oh), on the surface of the Moon.
Defeating the first 7 enemies using Sukapon allows the player to choose from 8 friendly robots, but the first level can only be accessed in the very first playthrough.
All matches are held one-on-one, and both characters start with a full HP meter and two hearts.
Sustaining large amounts of damage in a short period of time will cause the character to become temporarily unconscious, during which the player will be unable to move or attack.
In this mode, computer opponents will begin to use hidden moves and will fight far more intelligently than in the other two difficulty levels.
Dividing each character into individual sprites made animation much smoother, even in comparison with Super Famicom games.
This was also the largest roster in a fighting game, until the release of SNK's The King of Fighters '98, which has 38 playable characters.
