Rath is the Alpha-Omegatrix's DNA sample of an Appoplexian from Appoplexia.
Rath is about 9 feet tall and resembles a black and blue-gray bipedal tiger with one claw coming out of each wrist and no tail. He is also very muscular and has red eyes.
He wears the Alpha-Omegatrix symbol on his chest.
In Alpha-Omegaverse, Rath looks similar to his Alpha-Omegatrix version only with different eye brows.
He wears the Alpha-Omegaverse device on his chest.
Rath's personality resembles Wolverine's and that of a stereotypical high school jerk. This is demonstrated by Rath's tendency to use the phrases "Whatever" and "LEMME TELL YA SOMETHIN'!" when he's addressing anyone that he is angry with or about to fight, which appears to be a reference to Hulk Hogan's signature catch phrase, "Let me tell you something, brother." He also calls people by their full name (e.g "LEMME TELL YA SOMETHIN', MYSTERY KID WHO IS ALSO KNOWN AS MK AND HOOD!") or even, more humorously, (e.g."LEMME TELL YA SOMETHIN', E.V.O.LVED ALIEN AND DARAMA! He also likes giving people nicknames. Rath knows that his metaphorical statements make no sense, but continues to use them. He is very direct and fearless to the point of recklessness. Rath has super strength and agility, enabling him to jump great distances and lift objects heavier than himself.
Rath possesses a large, retractable black claw on each wrist. This claw can be used to stab and slice opponents or to create a shock wave when stabbed into the ground.
Whenever Rath gets determined or angry his claws seem to grow larger.
Rath's species knows how to retract their claws but Richard as Rath currently doesn't know how to retract his claws.
Rath is extremely durable, able to take a point-blank laser blast with no apparent effect and survive a free fall from several stories in the air with a bit of dizziness as a result.
Rath can also release a loud roar, although this seems to be more of an intimidation tactic rather than an offensive feature.
Even though he is not the smartest of Richard's aliens, Rath can perform fighting moves.
Rath's brain is hardwired for aggression and as such, Rath's only known weakness is his lack of intelligence and highly aggressive temperament. This causes Rath to become easily distracted and difficult to stop once he starts fighting.
Rath's apparent lack of intelligence also may convince him to needlessly argue with inanimate objects.
