Goosprite
Overview
This Kreature is the mutated result of splicing human genetic samples with an amorphous single celled organism. Though its default form resembles a female humanoid it is a gender-less blob which can suck out the DNA of another Kreature so it can morph into its likeness and use its powers. However, it does have several limits: its rank stays the same after it morphs, it can't morph into humans or other sapient beings, it can only stay morphed for a few minutes and it has to return to its default form before it can turn into something else.
Much as I change my mind as the archive updates, I’m pretty confident that if I were a tamer, I this would be the very first kreature I’d adopt. Maybe in a nice shade of purple.
