Appoplexians are a tiger-like species from the planet Appoplexia.


Appoplexians are about nine feet tall. They resemble muscular bipedal tailless tigers with scruffy fur and one black claw coming out of each wrist. They have green eyes and black stripes on shoulders, head, and upper body. They have white or cream on the jaw, neck, chest, stomach, hands, and feet and half-white/cream eyebrows. Their fur is either orange, maroon, or brown, and each individual has their own unique pattern of stripes.

Young Appoplexians lack the muscle mass of the adults and have more spheroid heads. They also lack stripes.

Powers and Abilities

Appoplexians demonstrate enhanced strength, being able to fight on-par with a Vaxasaurian,[1] punch through a solid wall, and lift a Cascan with ease.[2]

An Appoplexian's black claws are extendable, and can be used to slice or stab objects or enemies. These claws are also resistant against a Pyronite's fireballs.[3]

Appoplexians are capable of producing shock waves and powerful roars.

Just like Earth cats, Appoplexians possess enhanced agility and reflexes. They can also jump very high.

Appoplexians have enhanced senses, making them excellent trackers.[4]

Appoplexians are extremely acrobatic and capable fighters, as they have demonstrated numerous fighting tactics.

Appoplexians can climb up surfaces quickly and effortlessly. They can combine this with their strength to carry extra weight while climbing.[5]

Appoplexians are shown to be extremely durable, as shown when Rath managed to survive a rough fall from a cliff.[6] An Appoplexian's claws are also durable, as they could withstand Bashmouth's metal teeth.[7]

Appoplexians have enhanced speed and dexterity, as they can run on all fours.[5][8]


Appoplexians' brains are hardwired for aggression, and as such, their only known weakness is their lack of intelligence and highly aggressive temperament. It causes Appoplexians to become easily distracted and difficult to stop once they start fighting.

Similar to Tetramands, an Appoplexian's immense size makes moving through areas designed for smaller species difficult.[9]

Despite their enhanced strength, Appoplexians are physically weaker than Tetramands.[DR 1]

Similar to cats, Appoplexians can be distracted by mice[5] and laser pointers.[4][10] Like Bashmouth and most big cats, Appoplexians can also be distracted by meat.[8]

Like most actual cats yet unlike tigers, Appoplexians hate water.[11][12] Oddly, they are not always bothered by it.[5]

Appoplexians are vulnerable to the telekinetic abilities of a Celestialsapien.[13]

The name Appoplexian is a play on the term "apoplexy" (or "apoplectic"), which is a word to describe the state of being overcome with rage.


Reboot Appoplexians do not wear clothes unlike their classical counterparts.
