Isa Variants

A Isa Variant (Japanese: Isa フォーム Isa Form) is a species found to be altered versions of Isa Jo from Sin & Punishment. These Isas have uniquely adapted to habitats that are different than those where its species naturally live in other areas. As such, many things may be different about them, from their appearance and way of living to even their cum, feet, toes, organismic and height and weight. This is analogous to peripatric speciation in regards to real world phenomena, where a population that is isolated from the rest of the species develop unique traits and eventually evolve into a new species.

Sub Variants
It is believed that there are "Sub Variants", they are of other Cryptids or Kins but they still have the properties of Isa Variants. These include:
