Traits

The Horned mutation causes horns to appear on the head. This ranges between 1-5 horns. If a Pokemon already has horns, these have been seen to branch off of those or simply create more. They can be any colour in the Pokemon's palette or natural. 

The Spiked mutation appears as multiple spines on the body but never on the head. These can range from thick spikes to long thin spines. They can be any colour in the Pokemon's palette or natural. 

The Fanged mutation shows itself in numerous ways which is surprising given its rather basic addition. It can show as anything from saber teeth to boar tusks but always max at 4 extra teeth. These can grow from the top or bottom jaw. They can be any colour in the Pokemon's palette or natural. ​

The Winged mutation is one of the more highly praised or shunned based on whether those wings are feathered or webbed. These wings max at two and can be both feathered, webbed or one of each. They be any colour in the Pokemon's palette. The wings can attach at the shoulders or at the wrists of the normal front legs. Water-based Pokemon are often blessed with manta-like wings though these can appear on any Pokemon. Feathered wings may have multiple colors.

The Chimera mutation can ONLY happen to a pokemon fused with a DNA Nera. It seems something has gone horribly wrong and instead of a perfect mix, these Pokemon appear as two separate 'mons smashed together.

The Plated mutation can show itself subtly or extremely. It can be either a series of small raised scales or large overlapping plates. These can pretty much cover the entire body and can be any colour in the Pokemon's palette or natural. 

The Albino mutation can cause pokemon to appear either fully white or with faint markings, they are always pink or white tinted. They will always have pink, red, black, or blue eyes.

The Melanistic mutation will cause pokemon to appear either fully black or with dark markings. 

The Crystalize mutation causes crystal growth on the Pokemon. These crystals can appear anywhere on the body and come in any colour. They can be a custom shape or mimic real-life crystals. They cannot cover the entire Pokemon.

The Armor mutation causes bone-like structures to cover areas of the Pokemon that would otherwise be vulnerable. These structures often appear skeletal, such as skulls on the head and ribs on the body. They will can be any colour but will mostly appear in natural tones.
