XLR8 (pronounced "Accelerate") is the Omnitrix's DNA sample of a Kineceleran from the planet Kinet.


Ben as XLR8

XLR8 resembles a semi-armored Velociraptor. He has black orbs on his feet and wears a black conoid helmet with a visor that is part of his Kineceleran biology and isn't mechanical,[pop-up 1][1] leaving the other features of his head unknown. Whenever the visor does come up, one can see that he has a blue face, green eyes, black lips, and stripes above and on the right side of his eyes. XLR8 has five blue stripes on his tail, and wears black pants and a turtleneck-like shirt with a white stripe on the center.

In Back with a Vengeance, XLR8 wore a yellow raincoat.

In Ultimate Alien and Heroes United, XLR8 looked exactly the same as he did in the original series, albeit his skin was slightly darker and he was more muscular.

In Omniverse, XLR8 is now taller and the white color on his shirt is replaced by green, which now covers his whole neck. He has four blue stripes on his tail, the black balls on his feet are bigger, his helmet is longer in the back and front, his claws are longer and his visor is darker.

11-year-old XLR8 in Omniverse looks exactly the same as his 16-year-old self, except that he is shorter, and the green color of his shirt is white. He has three stripes on his tail.

XLR8 wears the original Omnitrix/Ultimatrix/Omnitrix symbol on his chest.

Ben 10,000 as XLR8

Ben 10,000's XLR8 was taller and more muscular-looking than his 10-11/16-year-old self. His arms, legs and tail stripes were white instead of blue, and there were less stripes on his tail. XLR8's clothing had longer sleeves with a pair of stripes under the shoulders and has an arrow-shaped symbol on his lower torso. He wore the Omnitrix symbol on his chest.

Ken as XLR8

Ken's XLR8 looked the same as 10-year-old XLR8 in the original series.

Gwen 10 as XLR8

Gwen 10's XLR8 is more upright. Her face lacks the black markings that Ben's has, as they are replaced with freckles. She has pink eyes and Gwen 10's hair-clips, as well as a black helmet. The majority of her outfit is dark blue with a light blue section around her neck that goes down her chest in a V-formation, light blue stripes on her forearms and wrists, two light blue stripes on the end of her tail, and a light blue stripe on each of her legs where the outfit ends. Her visor now has pink markings, and her hands are more human-shaped with claws for fingers. She wears the Omnitrix symbol on her chest with a cat shape surrounding it.

  • Speed-Enhanced Combat
  • Enhanced Dexterity/Accelerated Thinking

XLR8 can manipulate friction to reach speeds of 500 miles per hour within two seconds. XLR8 can accelerate so quickly that time appears to completely stop to him.[2] Kinecelerans seem to become faster as they grow older, seeing how XLR8 was capable of traveling globally in just a few seconds when used by Ben 10,000.[pop-up 2][3]

Basically, XLR8 can run so fast to the point where he cannot be seen until a camera's slow-motion is used.[2] He also appears to have more control over his speed than fellow speed alien Fasttrack, seeing as XLR8 could always stop immediately after running for a while, whereas Fasttrack can have trouble stopping if he runs too fast.[4] Furthermore, while XLR8 is implied to be even faster than Citrakayahs,[5][6] he is confirmed to be faster than Aerophibians on the ground.[DM 1]

XLR8 has very high dexterity, being able to type on keyboards or keypads at high speeds. Using this skill, he can input any code to deactivate devices.[7]

XLR8 can think, act and react at superhuman speed as well, as he was able to think of a million combinations in a few seconds while he was trying to remove SevenSeven 23's bomb from Ben 23's arm.[7]

XLR8 can deliver speed-enhanced attacks with rapid succession, such as excessively kicking or stabbing enemies with great speed and strength.

XLR8's speed gives him highly sharp reflexes, allowing him to dodge attacks with little to no effort,[8][9] and change direction very easily while running.

XLR8 is capable of creating tornadoes by generating a centripetal vacuum powerful enough to lift a To'kustar, either by running in a circular pattern or spinning at supersonic speeds.[10]

XLR8 is fast enough to run on water.[11][12] While doing so, he can even create water vortexes when he is either running in front of[11] or around his enemies.[13]

XLR8's scissor-like claws can cut through many materials with relative ease.[14]

XLR8 has enhanced strength, as he was able to carry a multitude of people, including Gwen, to safety without slowing down at age 10.[11][15]

In addition to his speed becoming faster, XLR8's strength seems to increase as he gets older as well, as he was able to carry Dr. Holiday in his arms with no trouble at age 16.[16] By age 30, XLR8 is strong enough to greatly damage Exo-Skull with physical attacks further enhanced by striking at rapid succession due to his speed.[3]

XLR8 can recover from injuries faster than any other species.[9]

XLR8's tail is prehensile, as he held a Null Void egg with it when he was about to trap Devlin 11.[17] This feat was first demonstrated when Kevin 11 used his tail to hang on to a wire after being pushed to the point of almost falling off a cart.[12]

XLR8 is able to cling to surfaces, either due to his claws, his agility, or a combination of the two.[15]

XLR8 can make opponents dizzy to the point of falling unconscious by grabbing them by their arms and spinning them around in a circle at a fast pace; this feat was exclusively demonstrated by Helen on Gwen.[18]


  • Vulnerable Tail
  • Poor Boredom Coping
  • Strength Limit
  • Stuck in Mud

XLR8's speed does not work on all surfaces; running on ice can slow him down,[19] whereas running on mud leaves him stuck in place.[17]

XLR8 can also be held in place if his tail is either stepped on[20] or held down.[21]

XLR8's speed can be used to an opponent's advantage, as shown when Ben Prime was left badly stunned when he ran into Princess Looma's outstretched arm.[22] Similarly, Gwen 10 experienced the same thing during her fight with No Watch Ben as Wildmutt.[23]

Despite his enhanced strength, XLR8 felt discomfort on his back from carrying Mr. Baumann over his shoulders.[24] Technically speaking, XLR8 is physically weaker than Citrakayahs.[MW 1]

XLR8 is very hyperactive and it can be difficult for him to stay focused, most notably shown when he got bored of looking at magic books and started reading a Sumo Slammers magazine instead.[25]


  • In Let the Games Begin, XLR8 looked for certain objects on the road so he could beat Gwen in a game of bingo.
  • In Gwen 10, Gwen used XLR8 off-screen to pick up some clothes she forgot to bring from home.
Ben 10,000
  • In Ben 10,000, XLR8 appeared thrice. Firstly, he defeated Exo-Skull. Later, he brought Ben and Gwen back to his headquarters. Then, he was defeated by Vilgax, forcing him to switch into Four Arms.
  • In Ken 10, XLR8 appeared four times. Firstly, XLR8 ran home to be on time to Ken's birthday party. Later, XLR8, along with Ken as XLR8, left home to stop Sploot. Afterward, when Devlin 11 broke into his headquarters, XLR8 attempted to imprison him with a Null Void egg, but failed. The next day, XLR8 fought Devlin 11 again.
  • In Ken 10, XLR8 went on his first mission with his dad only to get stuck to the floor by Sploot. Later, XLR8 was defeated by Kevin 11,000.

XLR8's name has the same sound as the word "accelerate", referring to his high speed. Otherwise, some translated versions of the series also call him XLR8, but in their respective ways of pronunciation, the names used for official dubbing don't fit the original international pun making them senseless.


  • Originally, XLR8 was the only Kineceleran on Earth because the slow rotation of the planet made other Kinecelerans sick after a few days.[pop-up 3][3] This was retconned in Omniverse, as several Kinecelerans reside in Undertown.[26]
  • XLR8's voice has changed over the course of his appearances:
    • In the original series, XLR8 spoke with a raspy voice.
    • In Omniverse, XLR8's voice sounds like a fast-talking, higher-pitched version of Ben's voice. There is also a buzzing-like sound effect that occurs whenever he speaks.
  • XLR8 is the final alien used in the original series.
  • XLR8 and NRG are the only aliens whose names are just letters that sound like a word that relates to them and their powers.
  • The speed that one needs to reach to be able to run on water is 30 meters per second (Mach 0.087), which makes XLR8 almost as fast as the speed of sound.
  • XLR8 was the winner of a Cartoon Network Ben 10 alien poll that only had the first twelve aliens.
  • XLR8's name was used in a Pop dance group in the Philippines.
  • In the online game Ben to the Rescue, XLR8's visor is miscolored green.
  • XLR8's name was used on a CD about different technical institutes by the Universal Technical Institute.
