Scylla

The Scylla is a super evolutionary predatory species native to Charybdis.

Not much is known about the past of the scylla, or all of Charybdis for that matter, there may have been a time where multiple species lived on Charybdis, where the ecosystem was not based on constant slaughter but now the planet is dominated entirely by scylla and vegetation.

All scylla can evolve and devolve physical and sometimes mental traits freely, effectively making them super predators, capable of completely adapting to a hostile environment in only a few hours. A Scylla can only evolve by consuming other scylla, which is why no scylla has ever been herbivorous, or omnivorous even. This is however partially due to some evolutionary limitations that all Scylla have. Scylla can not change their diet in any way, they must consume other scylla. When a scylla is consumed by another scylla, its DNA is absorbed and the victor unlocks the potential to partially evolve some of the traits from the predator it just killed.Some scylla rely on raw power and muscle, some on intelligence and poisons, some on pheromones and seduction, some may rely on dexterity and stingers and some may even rely on co-operation, hunting in small packs. Pack hunters, besides overly evolved predators, are usually regarded as the most dangerous kinds of scylla. After countless generations of breeding, it appears as though the humanoid body shape has been dominant. This has left almost all current scylla with humanoid body types, yet no Scylla could ever be mistaken for a human due to the predatory parts they always eventually grow and would most likely be born with.

Would a scylla physically evolve to predatory perfection, it would eventually evolve to form an arcane connection to Charybdis' magical core, unlocking near limitless possibilities for evolution.

A scylla with arcane abilities can evolve in ways most would think would be illogical, making it significantly easier for them to hunt, magical scylla naturally lose interest in lower prey and usually start hunting and breeding with other magical scylla. However, a scylla who has tapped into magical evolution can be felt by a sense that all Scylla have, they sense the presence of scylla with magic in their blood and will likely try to hunt down the scylla.

Scylla are animals in nature and although in rare cases some reach human level intelligence, they never let go of their animal instincts, it is not uncommon that lower scylla become pets for stronger ones for protection, or that some try to tame a stronger predators than themselves.
