Mega Man Zero/Unlockable secrets

Two Modes and one Rare Cyber-Elf can be unlocked, by clearing the game and meeting certain requirements. It is possible to unlock them all separately, as shown in the table below, but other ways are possible.

It is possible to unlock the Rare Cyber-Elf from Normal Mode, by meeting the same requirements. Similarly, it is possible to unlock Ultimate Mode before having unlocked the Rare Cyber-Elf and/or from Normal Mode, by meeting the same requirements.

Clearing the game at Rank A (or S) is not normally a requirement for Jackson, nor is successfully completing any missions. The only mode where those matter is Hard Mode, which inexplicably adds those extra requirements. This was tested across multiple playthroughs.


 * In Hard mode:
 * Weapons cannot earn experience and cannot be fully charged.
 * Elemental Chips cannot be used (exception: the Shield Boomerang).
 * You must clear the game at Rank A (or S) to get Jackson, in addition to what you would normally do on Normal mode.
 * About "Jackson mode":
 * Zero starts with the Jackson Cyber-Elf (plus all the cyber-elves he already collected).
 * The game is in the same mode (Normal or Hard) as the game that was cleared to unlock Jackson.
 * In Ultimate mode:
 * All cyber-elves with permanent effect are active without penalty on score.
 * Weapons are at max level since start.
 * Full-charged attacks can be instantly performed using button combinations.
