– Rath's main catchphrase.

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 original Omnitrix/Ultimatrix is located in the center of his chest. Both Gwen and Azmuth take these appearance cues as Rath.

In Heroes United, fur stuck out of Rath's arms, legs, chin, and head, and his muscles now have protruding veins when using his strength, making his appearance more pronounced and realistic in Generator Rex Art Style.

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 The 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, consisting of black boots, black gloves, and a luchador mask. Rath's claws are now greyish-silver instead of black, and the Omnitrix is now on his luchador belt.

Albedo as Negative Rath

In Alien Force, Negative Rath looked exactly like Ben's Rath but had red eyes and a red Ultimatrix symbol. In Ultimate Alien, Negative Rath lacked an Ultimatrix symbol.

In Omniverse, Negative Rath looks mostly the same as Ben Prime's Rath except his fur is recolored white, his stripes and skin are recolored dark pink, and his eyes are recolored red. In concept art, Negative Rath is naked yet wears a red Ultimatrix on his chest.

In Malgax Attacks, Negative Rath has clothing similar to the one Ben Prime's Rath gains in The Secret of Dos Santos. However, he lacks the mask and the tank top. He wears black shorts, red gloves and boots, a red belt with the Ultimatrix symbol on it.

Mad Ben as Mad Rath

Mad Ben's Rath has darker fur, orange eyes, and a hairstyle like his human form. He also has Mad Ben's Mad Max 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.


Rath's personality resembles that of a comic book vigilante and a stereotypical professional wrestler.

Rath almost always speaks in third person. Sometimes, when he 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 is self-aware that they do not 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. Rath's big mouth often gets him and his teammates into trouble, such as when Kevin tried to reach an agreement with Vulkanus, Rath began mocking the latter's defeats from them and called 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 this,[1] or their position, labeling Khyber as "self-proclaimed greatest huntsman in the galaxy".[8]

Rath 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 also does not make empty threats, as shown after saving the Tiffin and threatening to mutilate Jarett with rearrangement of his organs into a sweater if he started a war with the Lewodans, his low snarls hinted he meant it.[1] He also once outright admitted 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.[9][11][5] Similarly, he denied needing enhancements from Skurd against Exo-Skull.[12]

Over time, Ben has gained slight control of himself as 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".[13]

Because of Rath's extremely low intellect, Kevin can't 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 the Tiffin, though not at first.[1]

Rath does not have a very good sense of humor, as he gets mad whenever someone mistakes him for a "kitty".

Rath lacked the strong sense of shame his kind have, as he was always naked but had no shame.[14]

Rath sometimes yells out his special moves while fighting. These include Polaris Piledriver, Antarian Arm Bar, Ophiuchus Face-plant, Sirius Butt-Kicking, Cosmic Drop and Incursean Ambassador.

Ever since Skurd fixed the error with the Omnitrix that caused Rath to go naked, Rath is capable of speaking in Spanish, though it should be noted that this is a feature granted by the Omnitrix, and is not something that Rath naturally knows.[12]

Gwen and Azmuth as Rath

Azmuth and Gwen retain the personality changes of Ben's Rath, but in their regular voices. Azmuth as Rath also refers to himself as Azmuth rather than Rath.[15]

Albedo as Negative Rath

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

Mad Ben as Mad Rath

Mad Rath is the same as Ben Prime's Rath, but would start his catchphrase with "Oi!".[DJW 2]

Nega Ben as Nega Rath

Nega Rath would retain Nega Ben's dour personality.[DJW 3] He would also not say his usual catchphrase,[DJW 4] instead saying "I don't wanna tell you anything".[DJW 5]

Benzarro as Rath

Benzarro's Rath would be as backwards as Benzarro.[DJW 6] His catchphrase is "Let me no tell you things!".[DJW 7]

Powers and Abilities

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.[13] 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, which are sharp enough to cut through Attea's Incursean Blaster and a box.[7] These claws 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's also has a very strong bite force, as he was able to easily shatter SevenSeven's blade with his sharp teeth.[16]

Rath is extremely durable, being 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] and break through a concrete wall without showing any pain.[5]

Rath can run very fast,[17] and run on walls.[18]

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

Rath can balance on a giant yarn ball[7] and a unicycle.[19]

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] and a Techadon robot.[20] Rath either made up the moves himself or learned them from someone.[ES 1]

Rath is also strong enough to overpower female tetramands as he overpowered Looma on two occasions.


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]

Rath has very sensitive hearing, which makes him vulnerable to loud piercing sounds, such as a certain sonic frequency signal.[14]

Being a feline-based alien, Rath can be controlled by people that have the ability to control cats, like Nyancy Chan. He can also be easily distracted by a laser pointer.[7]

Rath can be trapped in a mana bubble. A lack of oxygen will cause him to pass out.[1]

Rath can easily be scared by Toepick's species.[DJW 8]

Despite his enhanced strength, Rath is physically weaker than Tetramands.[DR 1]

  • Dwayne McDuffie came up with both Rath's personality,[DM 1] and the wrestling moves he performed in Above and Beyond.[ES 2]
  • Rath is Eugene Son, Paul Eiding, and Yuri Lowenthal's favorite Omnitrix alien,[ES 3][ES 4][AC 1][YL 1] the latter of whom states that his love for the Appoplexian transformation is mostly because of John DiMaggio's voice acting for the character.
  • Appoplexians have an advanced sense of shame and typically wear clothes. However, Rath used to be naked all the time[14] because of "a horrible error on the part of the Omnitrix" that was eventually fixed by Skurd.[12] This change eventually became permanent.[DJW 9][DJW 10]
  • Out of all of Ben's aliens, Gwen and Kevin find Rath the most entertaining and amusing due to his mediocre intelligence, occasionally joking about him behind his back or out of his earsight.[3]
  • The Vreedle Brothers state that Appoplexians such as Rath 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]
    • When Rath is about to fight in certain episodes, the sound of a ringside bell can be heard.
  • In September 2011, FusionFall released Rath Nano.
  • Rath is replaced with 11-year-old Blitzwolfer in the opening intro of Omniverse's Arc 5.
