Generator Rex's Enemies

Van Kleiss

Van Kleiss

The main opponent of Generator Rex is Van Kleiss as the primary antagonist of the series. Van Kleiss has the same ability to control his nanites, just like Rex does, but his mutation is unstable and requires a constant supply of fresh nanites. He has extensive and quite impressive knowledge about the nanites. He is also familiar with the Rex’s past, which makes his part in developing conscience of that boy very special. Allegedly, he was worked on or been acquainted with the experiment which released them. He controls the Pack – a group of E.V.O.s, as his enforces which include members: Biowulf, Skalamander, Breach and Circe. Beside the Pack he also controls Abysus – the site of the Nanite Event. Abysus at the beginning was the birthplace for the all E.VO.s, but when Van Kleiss came to Abysus, he made it his home. If there’s the best way to describe the Abysus, it can be said that Abysus is a relatively small country where E.V.O.s are free from Providence, but they are slaves to Van Kleiss. Generator Rex often stray there in our free Generator Rex games, where his journey frequently ends with the fight.
Abysus is the place where Van Kleiss has absolute power and Rex is almost helpless there and all Abysus functions as the base of operations for The Pack.

Members of the Pack seem to be Van Kleiss most powerful E.V.O.s who are tasked with furthering Van Kleiss’ plans and they mostly represent the main way of supply with the fresh nanites for their master. Pack members are capable of commanding other E.V.O. s under the command of Van Kleiss. Based on that, Van Kleiss’ biggest wish is to expand the Pack for one more member who can control the machines and nanites better than Van Kleiss himself – for the Rex. If Rex falls into his hands, Van Kleiss will then have the ultimate power, and he will be unstoppable.

Biowolf

Biowolf

Biowolf – E.V.O. that strongly resembles an anthropomorphic metallic werewolf with the superhuman abilities. Biowulf is a skilled melee fighter with high level of strength, speed and agility. Biowulf's main weapon is his own body – he is always ready to use his razor sharp claws for example. Biowulf is always cold and cruel, the only thing that he cares about is his loyalty to Van Kleiss. When Van Kleiss was unable to lead the attack or operation, Biowulf is the one who always replaces him in the command. Biowulf is shown as a tactical leader of The Pack, but he does show very little care towards his underlings, because he rarely speaks, and when he does, it's usually to gloat or to relay orders to fellow subordinates.
Skalamander – huge humanoid lizard E.V.O. with crystal spikes growing out of his body. He has a crystal club growing out of his left arm and it appears as his main weapon. He can fire spikes out of the club or grow it into a shield. It is unknown whether Skalamander was a human or animal before he became an E.V.O. He can be described as very strong but quite stupid member of the Pack, who gets along very well with Biowulf and who is also very loyal to Van Kleiss. Skalamander

Skalamander

Breach

Breach

Breach – emotionally disturbed black-haired and four-armed female E.V.O. She has the ability to create portals of varying shapes and sizes for multiple purposes, which makes her dangerously unpredictable - she can tear open reality itself. Using her larger arms, Breach can tear open reality and space, creating variously shaped portals. She can use these portals to transport herself and others to a location randomly or that she has designated. Unlike other members of the Pack, she speaks and acts on her own whims at the most. If she feels threatened or if she finds something that she like, she will use pocket dimension to send that into it, because that is her stolen city, which she uses to store her "toys".
Circle – female E.V.O. with black and red hair. She has the power and ability to project unusually strong and powerful sonic waves from her mouth. She is capable of transforming her mouth into an “insectoid” type mouth and distributing ultrasonic waves much like a bullhorn. She can also attract other E.V.O.s using her call, hence her name. She also learned Hand to hand combat. As the member of the Pack, she believes that Van Kleiss is the only hope E.V.O.-kind has left, despite her recognition that Van Kleiss' methods are too aggressive. Circe believes that it is ultimately impossible for E.V.O.s and humans to get along in the world. She will do whatever it takes to help E.V.O-kind.
