Agunima

is a mysterious wizard that appears as a middle boss in the Dancing Dragon Dungeon of. Due to the fact that the boss went unnamed in English, he is commonly, and perhaps intentionally, confused with Agahnim the Dark Wizard.

Characteristics
Agunima is similar in appearance to both Carock and the aformentioned Agahnim, as well as Wizzrobes, which also first appear in Dancing Dragon Dungeon. Like Agahnim, he also splits into three; two copies and one real. He and his copies will appear in various locations throughout the room and attack with balls of magic. Unlike those used by Agahnim, these cannot be deflected by a blade, nor can they be stopped with a Shield. With the lights out, Agunima cannot be harmed at all; but if Link lights the torches in the center of the room using Ember Seeds his true form will become vulnerable, similar to the technique of Darkness used by Ganon. The copies will remain invulnerable, but with the lights on Link can discern the real Agunima from the copies by being able to see his shadow. Striking him with the Wooden Sword will cause damage and cause him to stop casting magic briefly.

As with other middle bosses, upon destruction Agunima will leave behind a Fairy and a warp that will lead Link to the start of the dungeon. When defeated, Agunima spins on the spot briefly before exploding, similar to Agahnim spinning on the spot after being defeated in.

Oracle of Seasons (Himekawa)
Agunima makes a brief appearance in the depicted in a cutaway showing various monsters and bosses from the game alongside General Onox. In this scene, these monsters are simply described as minions of Onox. Unlike other monsters depicted here, Agunima does not make any further appearance in the manga.

Trivia

 * Agunima's name is identical to Agahnim's Japanese name, except for the final kana, マ (ma) instead of ム (mu). Rather than a spelling mistake, this appears to be intentional to distinguish him from the real Agahnim.
 * Whether Agunima is a weaker copy of Agahnim, a true alter-ego to Ganon similar to Agahnim and potentially the Magician, or simply an unrelated minion of General Onox or Twinrova is never made clear.
 * Hyrule Historia revealed that Ganondorf, Ganon's human form was designed but went unused in the Oracle Series. It is therefore possible that this enemy was originally meant to be the true Agahnim, but was changed to a minor boss during development for related or similar reasons.
