Seraph

Seraphs (セラフ Serafu) are a race of primordial beings and are one of the oldest living races in existence predating even Angels.

Racial Traits
Unlike Gods of Destructions and Angels; Seraphs actively do not eat and don't possess the ability to process food.

Seraphs possess near-absolute immortality with no known way to die although it is implied that Seraphs can die.

Appearances
Seraphs typical possess similar features to Human-type Earthling such as skin tone, hair colours, while almost completely possessing a different spectrum of eye colour such as Hot Pink, Gold, Brilliant Blue, Scarlet Red, and Dark Brown.

Personality
Unlike Angels; Seraphs display a similar level of compassion and emotions to that of a typical mortal and show genuine concern in certain situations.

Power
Seraphs possess unfathomable might, having power beyond and creation skills similar to the Supreme Kais. Their ki is described to be similar, but heavier than Angel Ki. Many of the abilities they can grant are; Erase, Immortality, Temporal Immunity, Ki Sense Awareness, and Knowledge.

Seraphs also have the ability to disguise themselves as Angels.

Unlike Angels; Seraphs are not bound by any laws or restriction that prevent them from interfering and seemed to possess prophetic abilities.

Relationship with Angels
As evident by the conversation between Whis and the Grand Minister; Angels have no clue of the existence of the Seraphs while Seraphs seemingly detailed knowledge on all creatures in existence including Angels. Seraphs generally don't view Angels in a great light due to their apathetic attitude and Angel laws.
