Asguiaro Ebern

is a Quincy of unknown allegiance or motivation.

Appearance
Ivan is a man of both tall and slender build. He has short, light-colored hair that is swept back, creating peaks at either side of his head. A white mask with three holes in it covers his left eye, reminiscent of an Arrancar, whilst his right eyebrow unusually points upwards. His attire consists of a long, white, double-breasted trench coat that features shoulder straps and is tied using a black belt at its waist, which is adorned with a decorative buckle. This is worn over white trousers and trench boots.

The Thousand-Year Blood War arc
Appearing suddenly in Ichigo Kurosaki's bedroom, just as Ichigo inquires about Ryūnosuke Yuki's name, Ivan responds instead and declares his own full name, before asking if there were any other questions. Firmly told by Ichigo to get off of his bed, Ivan refuses to comply despite Ichigo repeating himself and so, is kicked out of the window. As Ivan holds his head outside and wonders why he was struck, Ichigo demands to know what business he has with him, but Ivan appears confused. Drawn away from Ichigo's house, Ivan denies being an Arrancar upon being questioned and instead reveals himself as a Quincy. Forming a large weapon, he asks Ichigo if his powers seemed familiar.

Taunting Ichigo as he attacks, Ivan becomes elated when Ichigo finally activates his Bankai, noting to himself that it will be the end of Substitute Shinigami's Bankai. After preparing a special technique and reciting an incantation, he manages to damage Ichigo's arm, but Ichigo quickly breaks free from the attack and fires a Getsuga Tenshō towards a stunned Ivan.

Equipment
Quincy Cross - As with most Quincy, Ivan is shown to carry a cross. His particular version consists of five points and is worn on his left wrist.

Powers & Abilities
Reiryoku Absorption & Manipulation: A Quincy primarily absorbs spiritual energy from the atmosphere and combines it with their own spiritual energy to form weapons. Using this ability, Ivan has been shown to be able to create a crescent-shaped weapon that is several times his own size and features four cannon-like protrusions, which are each capable of firing powerful blasts of spiritual energy.

Spiritual Awareness: As a spiritual being, Ivan can sense other spiritual beings.
