Changeling

Changelings are usually metahumans that have aberrant metagenetic traits (however, members of non-metahuman species can also mutate into changelings). Changelings are neither a race nor a metavariant. Each is an unique “freak of nature”.

Changelings are categorized as Class I, II or III depending on severity of mutation.

Mutations
Changelings are humans or metahumans that expressed some unique or aberrant genotypes when Halley's Comet returned in 2071 A.D. The Genotypes ranged from animalistic expression, to plant-like expressions, to even stranger expressions.

Class I SURGE: Class I Changelings seem to have manifested an incomplete phenotype; or have acquired traits that don't belong to their metatype.

Class II SURGE: Class II Changelings have a mixture of human and animal traits, but not to the extreme as Class III.

Class III SURGE: Class III Changelings has resulted in the most unusual gestalts. The combination of human and animal gestalts results in "animal people" (or "furries" as they are derogatorily called). Also genotypes have manifested resulting in humans with hybridization that leaves geneticists baffled. Perhaps the "Junk DNA" recorded by the Human Genome Project has been awakened somehow.
