Rath is the Omnitrix's DNA sample of an Appoplexian from the planet Appoplexia.


Ben as Rath

Rath is about nine feet tall. He resembles an orange and white bipedal tiger with one black claw coming out of each wrist and no tail. He is also muscular and has green eyes and black stripes on his shoulders, head, legs and upper body as well as a white jaw, neck, chest, stomach, hands and feet. The Omnitrix/Ultimatrix is located in the center of his chest.

In Heroes United, fur stuck out of Rath's arms, chin, and head, making his appearance more pronounced.

In Omniverse, Rath looked similar to his Alien Force and Ultimate Alien appearance, but was more muscular, with longer and more pointed eyebrows which were completely black (except in his first reappearance). His fur appeared darker as well.

In Secret of Dos Santos, Skurd fixes the Omnitrix error that made Rath naked by giving him an outfit similar to that of a luchador (a Mexican masked wrestler). Rath's luchador outfit has a green and black color scheme. He also wears black boots, black gloves, and a luchador mask. His claws are now greyish-silver instead of black, and the Omnitrix is now on his luchador belt.

Mad Ben as Mad Rath

Mad Ben's Rath has darker fur, orange eyes, and a hairstyle like Mad Ben's. He also has Mad Ben's Mad Ma- style silver plates with orange spikes on his shoulders, lower arms, and calves. The Omnitrix symbol is on a black panel on his chest and is colored orange. He is also slightly thinner than Ben Prime's Rath.

Albedo as Negative Rath

In Alien Force, Negative Rath looked exactly like Ben's Rath but had red eyes and his Ultimatrix symbol was red as well.

In Ultimate Alien, he lacked an Ultimatrix symbol.

In Omniverse, Negative Rath has white fur instead of orange and has dark grey stripes. He now has clothing, just like Ben's Rath. However, he lacks the mask and the tank top. He has black shorts, along with red gloves and boots. He has a red belt with the Ultimatrix symbol on it.


Rath's personality resembles that of Marvel Comics' Wolverine and a stereotypical professional wrestler.

Rath almost always speaks in third person. Sometimes, when Rath becomes extremely angry, he mixes up metaphors (such as "a man's food is his castle"[1] or "you just bit off an eye that's bigger than your stomach can chew")[2]. He acknowledges they don't make sense, but still continues to use them anyway.

Rath's muscle-over-brains mindset makes him needlessly argue with everyone around him. He even shouts at inanimate objects, like a hole he made in the ground, a stolen spaceship, gravity,[3] water,[4] fire, the Omnitrix[5] and Ultimatrix[6] for their malfunctions, the Proto-Tool's laser pointer, a giant ball of yarn,[7] and a paper bag on his head, arguments of which were ridiculous and that occasionally lead him to harm both himself and others. His big mouth often gets Rath and his teammates into trouble, such as when Kevin tried to reach an agreement with Vulkanus, he mocks the latter's defeats from them and calls him "baby man", resulting in the negotiation downgrading into a fight.[1]

When Rath is angry at someone or something, he usually yells a sentence starting with, "Let me tell ya something" followed by the full name of the person, calling Kevin by his,[1] or their position, labeling Khyber as "self-proclaimed greatest huntsman in the galaxy".[8]

He is very fearless to the point of recklessness, as he didn't hesitate to literally jump down Jarett's throat to rescue the Tiffin or about firing the Vreedle Brothers out into space after they blasted him and his tray of food. Rath doesn't make empty threats, as shown after saving Tiffin and threatening to mutilate Jarett with rearrangement of his organs into a sweater if he started a war with the Lewodans, his low growl hinted he meant it.[1] He also once outright stated he intended to hit Rojo in the head during a train robbery.[9] Ben even agreed with Gwen's premonition that Rath would do something unthinkable if he ever went after J.T. and Cash upon learning about them taking credit for his heroics.[10]

Rath has a lot of pride in his capabilities and himself, expressing bluntness or anger instead of gratitude when Gwen and Rook saved him on several occasions and denied needing enhancements from Skurd against Exo-Skull.[11]

Over time, Ben has gained slight control of himself when he's Rath. He once lowered his voice when talking to Gwen on the phone, even though he had two Forever Knights at his ferocious mercy, and mildly called her unempathetic response "harsh".[12]

Because of Rath's extremely low intellect, Kevin cannot help but mock or make fun of him.

Despite the fact that Rath is supposed to know nothing but anger and fighting, he is shown to be friendly towards Tiffin, though not at first.[1]

Rath lacked the strong sense of shame his kind have, as he was always naked but had no shame.[13]

In Secret of Dos Santos, he starts to speak Spanish due to Skurd's effects.

Albedo as Negative Rath

Unlike Ben, Albedo has better control over his temper as Negative Rath because of his superior intellect.[DJW 1]

Powers and Abilities

  • Enhanced Strength
  • Enhanced Speed/Quadrupedalism
  • Shockwaves
  • Powerful Roar

Rath possesses enhanced strength and agility, enabling him to jump great distances and lift objects heavier than himself. This was shown by how he was able to easily dismember the Forever Knights' paramilitary tank via brute force and toss the still extremely large pieces around (with one hand and later with two for the tank's body) with minimal to no effort.[12] Rath's strength also gives him an advantage in combat, allowing him to power his way through many opponents and smash through tough defenses.

Rath's unbridled aggression gives him a psychological edge in combat. There are very few things that Rath fears and many opponents find it extremely difficult to beat him if he is fully enraged.

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.[1]

Rath is extremely durable, able to take a point-blank laser blast with no apparent effect and survive a free fall from several hundred feet in the air with only a bit of dizziness as a result.[3] He can also run very fast.

Rath can also release a loud roar, although this seems to be more of an intimidation tactic rather than an offensive feature.[1]

Even though he is not one of the smartest of Ben's aliens, Rath can perform fighting moves with expert execution, as seen when he used wrestling moves to defeat Manny.[2]


  • Rath's hydrophobia
  • Rath being hypnotized
  • Deadly sonic frequency

Rath's brain is hardwired for aggression and as such, Rath's main 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. He is also not quite adept for diplomatic approaches, particularly negotiations, and can make bad or difficult situations worse.[1]

Rath's apparent lack of intelligence also often convinces him to needlessly argue with inanimate objects.[3]

Rath is scared of water, like most actual cats, but unlike actual tigers.[4]

Rath can be subdued by the Hephestan Neuro Grip.[8]

A certain sonic frequency signal is fatal to Rath.[13]

Rath, being feline based, can be controlled by people that have the ability to control cats, like Nyancy Chan.[7]

  • Appoplexians have an advanced sense of shame and typically wear clothes, unlike Rath, who used to be naked at the time.[13]

  • The Vreedle Brothers state Rath and other Appoplexians are much more aggressive and dimmer than they are.[1]
  • Similar to Echo Echo and Atomix, whenever Rath executes wrestling moves, he names them after stars.[2]
  • In September 2011, FusionFall released Rath Nano.
  • Rath was the fourth alien to be manually unlocked by mistake in the Omnitrix, the first three being Cannonbolt, Wildvine and Ditto and the fifth being Atomix.
