The Black Rabite or Grim Rabite is a black or dark-furred Rabite occasionally encountered in the Mana series. It is typically a paragon of the Rabite species as a whole and acts as a megaboss in Trials of Mana and a special upgrade monster in Sword of Mana. It is hard to find or unlock, and has powers well beyond those of a normal Rabite.
Only approachable in the Duran/Angela storyline, the Black Rabite is an incredibly powerful monster, capable of high-level magic spells, summoning Level 99 demons to assist it, and absorbing Darkness-based attacks. It is popularly considered to be the most powerful adversary in the game, and arguably in the Mana series as a whole.
When battling against the Black Rabite, "The Sacrifice - Part Two" will play. This battle theme is shared with the three final bosses (and plays for the first half of each battle against one of them).
No official art exists of the Black Rabite.
The remake alters the Black Rabite battle significantly, as it is now accessable with any character. Once a player has beaten the last story dungeon in Trials of Mana they must then proceed to area that they visited just before. This will vary based on the character that the player chose, and those that have picked Angela and Duran must visit Crystal Desert, those that have picked Charlotte and Kevin must visit Mirage Palace, and those that have picked Hawkeye and Riesz must visit Night Cavern.
The Black Rabites encountered here are considerably less powerful than the one in Trials of Mana, but they are still far more powerful than their normal counterparts. They are unlocked by defeating 999 Rabites. The "defeat 999" process produces Black/paragon upgrades of all non-boss monsters, not just Rabites.
The Black Rabite is known as the Grim Rabite.
The Black Rabite is a hidden boss in a bonus mission, but unlocking him is almost as hard as beating him. He appears in a stage that is only unlocked after beating the game on hard mode, and even then he will not appear until you have sent 999 regular rabites to their deaths throughout the game.
