XLR8

XLR8 (pronounced: accelerate) is the Codon Stream's DNA sample of a Kineceleran. His home planet is Kinet. Ben first transformed into XLR8 at the end of the episode And Then There Were 10, when he decided to play around a bit with his new found power, using the form to get revenge on some bullies that he fought with earlier in the episode.

Appearance
XLR8 resembles a semi-armored velociraptor, the base creature for the form's design. XLR8 has wheel-shaped feet and wears a helmet with a visor, which is part of his alien biology, leaving the features of his head unknown. Whenever that visor does come up, you can see that he has green eyes and black lips.

Ben 10,000's XLR8 has a scanner built into the helmet, the product of nanotechnology Ben 10,000 uses to enhance his aliens. The Bandai profile for XLR8 describes the actual species much differently.

Powers and Abilities
XLR8 can manipulate friction to reach speeds of 500 mph (approximately 805 kph) in an instant, and the same power allows him to climb up walls and run on water with relative ease. Using his speed, XLR8 can perform a number of unique feats. He can create tornadoes through centrifugal force, either through running in a small circle or spinning, and can deliver speed-enhanced attacks in rapid succession. Amazing reflexes accompany this speed, allowing XLR8 to quickly dodge attacks with relative ease. His scissor-like claws can also cut through objects.

Weaknesses
XLR8's weakness is his lack of physical strength, which is about on par with a normal human. His speed does not always work on all surfaces, like ice or strong adhesives. Magnets and charged pulses are said to be a problem, apparently disorienting XLR8 to the point that he cannot balance properly, but the series has never addressed this weakness.

Original Series

He accidently turned into XLR8 when he wanted to fight the Krakken as Ripjaws in The Krakken. He beat up Kevin's rivals in Kevin 11 and managed to escape before Kevin could see Ben Tennyson. He later tried to destroy the evil Rojo in The Alliance and defeated Hex in Lucky Girl. He later battled Vilgax in Secrets and lost. Later, in the following episode Truth, he defeated Phil and his Wigsilian Org Beast. He failed to destroy The Great One in The Big Tick and defeated Sixsix and Vulkanus in The Galactic Enforcers. He was later used to find Max in Camp Fear. He had 6 appearances in Back With a Vengeance and was used by both Ben and Ben 10,000 in Ben 10,000. He was used twice in Under Wraps, to fight The Mummy and collect the chicken eggs, then twice in The Unnaturals, once to defeat the Squires and next to hang JT and Cash. He appeared in Monster Weather, to fight S.A.M.. He duelled Dr. Vicktor in The Return, before changing back after he revived Zs'Skayr. He defeated Enoch for the final time in Perfect Day before he was used in Ben 4 Good Buddy, to duel the Road Crew. He was used by both Ben 10,000 and Kenny Tennyson in Ken 10, later used in Ben 10 vs The Negative 10 (Part 1), to battle the hypnotized security guards. He was used in the non-cannon episode Goodbye and Good Riddance to hold Vilgax until his father incinerated him. The third version of Ben 10: Secret of The Omnitrix showed him activating self-destruct.

Naming and Translations
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.

Protector of Earth
XLR8 is the third alien Ben obtains. He is useful in fights and bosses. The main thing you will need him is to go to a lever, make him speed to it and to the other lever to complete the levels. XLR8 has a Dark Heroes and DNA Force skin. His dark heroes skin erases his visor replacing it with a red robotic stripe.
