Ai

Ai is a mysterious being and one of the Five Great Calamities that humanity met in the Dark Continent.

Appearance
Little is known of Ai appearance but he seems to look like a gas life-form.

Background
When the Repubblic of Mimbo, after enlisting the help of the Hunters Association, sent an expedition to the Dark Continent searching for "the three primary liquids" they were surrounded by Ai. After a still unknown dispute or struggle ensued only three survivors returned, but empty-handed and without even a shred of their sanity.

Abilities & Powers
Not much is known about Ai's abilities, but according to Ging Freecss the level threat of Ai, like that of the other Five Great Calamities, is even greater of that of the Chimera Ants.
