The villain you are looking at is Annihilat. They are a being made of K3 corruption. They are an almost pure manifestation of an amount of it able to fill a suit meant for an "old scientist". It has tentacles made out of K3 corruption that go through some holes in the suit, and the suit has many unseen features, and it has plenty of ways to kill a flesh based human. Annihilat has gained a mind of it's own from his countless victims being absorbed into it, it is part of the council of the K3 corruption collective mind, which controls the entire K3 corruption through several inputs. K3 corruption shall be more elaborated on in an new/old series that I once planned, called Find Flower. The series shall center around a girl that was the result of some science experiments on plants called Flower. Flower can control every single bit of plant life, and utilize plants to her advantage. However, she ends up being split into separate personalities, making most of the series about getting her personalities back together into Flower again. Annihilat is going to be one of the ONLY connections to Find Flower Adventerror will have, since I want it and another game series to be more by their selves.
