This is what we have from Rumple's document.
Strains:
Strain Creation: Strain testing likely all occurred at one location (occurring at Tartarus in Legacy), and is not directly tied to the base creatures that the strain is applied to.
Hyperendocrin (Type-H): Significantly larger, stronger, and more dangerous than normal. Increased metabolism leads to inevitable starvation. Armored appearance.
Neurotenic (Type-N): Potentially can interact with the electromagnetic spectrum (as seen with Echidna/Neurotenic Mastermind). The NHJ (event) is linked to Neurotenics; however, to what degree? We are uncertain. However, IN LEGACY, expelled bio-materials that, when in contact with a living foreign body, were dangerous.
Tissoplastic (Type-T): Has better regeneration and can regenerate lost/destroyed limbs.
Strain Plants:
Metallivore: A metallic vine that grows over and consumes metal, eventually covering and maintaining the shape of things it has consumed, similar to strangler fig trees. Forms occasional leafy “knots” periodically along main roots/rootlike structures..
Mendys: A carnivorous plant with corms or spuds that uses clawlike thorns at each stem node to capture and kill prey. Its flowers change color just before it strikes, and it grows like ivy (potentially mimicking it to lull potential prey into a false sense of security). The name may translate to “bad liar” as a compound word of Latin and Greek origin, or relate to whoever created this Strain.
Razorbark: Essentially ‘living barbed wire’, sporting only heavily thorned branches and twigs with no/a lack of leaves. It can attach itself to almost anywhere within reason via little graspers that it uses to adhere to walls or other not-so-upright surfaces, which sprout from the base of a clump.
ArborBurst Redwood: From what we can see from artworks, the ‘ArborBursts’ have a ‘burst’ period containing extreme growth and a more armoured appearance with a unique bark-appearance. It is unclear if ArborBurst could refer to a parasitic plant that sprouts out and mimics certain traits of a host plant, if “ArborBurst Redwoods” are a modified type of redwood or ‘other’.
