Ben Tennyson
Ben is a typical 10-year-old boy - he plays video games, rides his bike, and sometimes gets into some mischief. During a camping trip with his grandfather Max, and his cousin Gwen, he finds the Omnitrix, an alien device that gives him the ability to turn into different aliens. Unable to remove it, he uses its powers to become a superhero. He finds the job trickier than he imagined, especially with the evil alien warlord Vilgax pursuing him relentlessly to retrieve the Omnitrix. No matter what bizarre form Ben takes, however, he's still the same good-hearted yet mischievous 10-year-old boy inside.
Aliens!
Diamondhead
Diamondhead is an alien whose body is made of an organic crystal, making him invulnerable to most physical attacks. He can grow crystal on any part of his body to make simple tools that are extremely sharp, allowing him to cut and slash his way through almost anything. His ablillty to grow crystal also means he can regenerate any part of his body. He can also fire crystal shards as projectile weapons. His crystalline body-structure allows him to reflect light- and beam-based weapons. Like any crystal, sonic weaponry will shatter his body.
Advantages
*Is nearly invulnerable to damage.
*Can morph his body-parts into extremely crude, yet sharp, tools and weapons.
*Can refract both light- and beam-based weaponry.
*Can fire crystal shards as razor-sharp projectile weapons.
*Can grow crystal over other objects.
*Can regrow lost limbs.
Disadvantages
Sonic-based attacks will shatter Diamondhead's crystalline body. His body can also shatter if hit against tough objects, though he can regrow body parts.
FourArms
A member of an alien race known as Tetramands (tetra meaning "four" wink , Fourarms is built for close combat. Standing twelve feet tall, this formidable, four-armed alien can use his tremendous strength to dish out punishment, while his armored body protects him from taking it. However, all the added muscle-mass and his large size makes Fourarms slow on his feet.
Advantages
*Has tremendous strength.
*Has extremely thick, armored skin.
*Has heightened endurance.
*Can leap great distances.
*Can create sonic waves by clapping all four hands at once.
Disadvantages
While not clumsy, Fourarms has limited agility due to his large size and excess muscle-mass.
GhostFreak
Ghostfreak is a shadowy, phantom-like alien, composed of protoplasm that can change its density. This allows Ghostfreak to phase through matter and turn completely invisible at will. He only has one eye, but can position it almost anywhere on his body by moving it along a track traced on his skin. His ghastly appearance is also good for putting fear into the hearts of criminals everywhere. In fact, even Ben gets a little creeped out when he changes into Ghostfreak. Ghostfreak has the unique ability to peel back his own skin, revealing a horrifying mass of innards. Direct light and certain chemicals will nullify Ghostfreak's invisibility and intangibility.
Advantages
*Can become intangible (move through solid matter) at will.
*Can become invisible (unable to be seen by the naked eye) at will.
*Can fly, though not as quickly or as expertly as Stinkfly can.
*Can move his eye along a track traced on his skin.
*Can peel his own skin off to reveal a mass of black and gray tentacles beneath, as well as something else (unseen) that is presumably far more disturbing.
Disadvantages
Direct light, as well as certain chemicals, will render Ghostfreak's invisibility and intangibility useless. He is also not as strong as some of the other alien forms.
GreyMatter
At a mere five inches tall, Grey Matter is a part of the alien race known as Galvan (of the planet Galvan Prime), which are bred to enter complex machines and repair them from inside. Consequently, he's able to squeeze through incredibly tiny spaces. They were also bred to be highly intelligent, so Ben gets a boost of intelligence when using this form. He also knows things that he normally doesn't, such as the names of various alien technologies, and even alien physiology. This is either through an advanced form of intuition or genetic knowledge. Unfortunately, he is vulnerable to attack in this form since it isn't meant for fighting. He can, however, use this form's knowledge of all things alien to exploit an opponent's weaknesses.
Advantages
*Has enhanced intelligence, which allows him to quickly understand and operate any form of technology, as well as determine an opponent's weak point.
*Can respond quickly to his environment.
*Can squeeze through incredibly tiny spaces.
*Has slimy skin that sticks to walls, allowing him to climb most anything.
*Can jump several times his own height.
*Has sharp teeth.
Disadvantages
Grey Matter's size makes him weak and easily trampled. Unlike the other forms, he is not meant to be used for combat.
HeatBlast
Heatblast comes from an alien race known as Pyros that lives on a star called Pyronite, rather than a planet. He can project bolts of fire from his hands and mouth and create balls of fire that he can throw or roll. He can also absorb both flames and heat, meaning he can put out a fire as fast as he starts one. Heatblast can apparently take a surprising amount of punishment, as he survived getting knocked through a few several-story buildings without any serious injuries. Heatblast can be put out like any fire, but it takes a substantial amount of effort to do so. Heatblast, unlike all the other cold-affected alien forms, actually gains powers when affected by Earth-based viruses. In his case, his powers reverse, allowing him to control cold instead of heat.
Advantages
*Can project bolts of fire from his hands.
*Can project a concentrated stream of flame from his mouth.
*Can rocket himself through the air by blasting flame from his feet, and do the same to cushion his landing.
*Can create fireballs to throw or roll.
*Can absorb heat/fire as well as create it.
*Can ride on a column of flame like a surfboard.
*Can create a smokescreen for a quick escape.
*Can travel short distances in a vortex of fire.
*Has cold-based powers while suffering from the rhinovirus, commonly known as the common cold.
Disadvantages
Any items that extinguish typical fires, such as water, can kill Heatblast if used in excess. Otherwise, he'll just reignite after a short wait. The only exception to this is when he's sick, since the water will simply freeze when it comes in contact with Heatblast's body.
Ripjaw
Ripjaws species is from the species Aratarann from the planet of Ara Taris. The aquatic alien Ripjaw is an extraordinary swimmer and, like many aquatic creatures, he can breathe underwater. He has a very large tail with fins that allows him to swim at incredible speeds with great agility. The tail can separate on land, revealing a pair of legs within. He has sharp claws and powerful jaws that can unhinge to deliver a devastating bite. Ripjaw can only remain on land for a short time before needing to get back in the water, since he'll dehydrate like any fish if given enough time. This form is the least used of any form due to its specialized nature.
Advantages
*Can breathe underwater.
*Can morph legs into a tail with fins and back again.
*Is a fast and agile swimmer.
*Has sharp claws and powerful jaws.
*Has a luminesent dangler, allowing him to see in dark places.
Disadvantages
Ripjaw is rendered useless on dry land after a short period, although he can breathe air normally; he does not walk very well and his gills must be kept wet or he'll dehydrate rapidly.
StinkFly
Stinkfly is a winged, insectoid alien and an expert flyer, his species is known as Lepidopterran and are able to pull off amazing acrobatic moves in midair. He can take care of himself in a fight, using his pincers and sharp tail as impressive natural weapons. He can also shoot combustible slime from both his mouth and his four eye-stalks. He can also carry many times his own weight, as evidenced when he managed to stay in the air despite having Vilgax hanging from his tail. Much like Earth insects, he has a tough exoskeleton, but very thin wings.
Advantages
*Can fly expertly thanks to his thin, rapid-moving wings.
*Can lift many times his own weight while in flight.
*Has six pincer legs and a razor-sharp tail.
*Has a 360? field of vision thanks to his four movable eye-stalks.
*Can spit slime from his mouth and eye-stalks (the slime is combustable, but only at high temperatures).
*Can cling to slanted surfaces.
Disadvantages
He is weak against poisonous gases and water. The latter of the two can render him incapable of flying if too much gets on his wings.
Upgrade
A living machine with a liquid, metallic body and a system of organic circuits, Upgrade is a biomechanical alien that can merge with any mechanical device. Its species name is not yet known. While merged with a device, he can "upgrade" it, making it far more advanced than any equivalent Earth technology. He can also fire a powerful positronic beam from his single eye, regardless of whether or not he's merged with another device. The downside is that he is vulnerable to electricity and electromagnetic fields, as well as acids and corrosives. Upgrade is the only form where Ben's voice does not change, although it does sound more hollow and distant than normal.
Advantages
*Can merge with and control technology.
*Can upgrade technology, giving it capabilities far beyond its original design.
*Can fire positronic energy blasts from his single eye.
*Can create hard-light constructs (spikes, for example) out of positronic energy.
*Can stretch his body to an extent, allowing him to glide or float.
Disadvantages
Acids and metal-corrosives can dissolve Upgrade. Since he's made of metal, electrical attacks are far more effective. Electromagnetic pulses can also render him useless. Also, when controling a sentient robot, he is weak to control it.
Wildmutt
A close relative of an alien species known as Vulpimancers (literally "fox wizards" wink from the planet Vulpin, Wildmutt is less humanoid than most of the Omnitrix's forms. More akin to a canine, Wildmutt is an alien with superhuman athletic ability and heightened senses of smell, hearing, and taste. The downside is that this form has no eyes. His lack of vision is supplemented by his other senses, which works almost as well as actual vision (appears as red figures against a green backdrop). Wildmutt cannot communicate verbally (at least in human languages), but can growl, grunt, and make other similar noises. The razor-sharp quills on his back act as projectile weapons, and he can fire them with amazing accuracy.
Advantages
*Has superhuman athletic ability.
*Has heightened senses of smell, hearing, and taste.
*Can fire razor-sharp quills from his back (unused so far).
*Has radar-like "sight" thanks to his enhanced hearing and smell.
*Can sense humans and objects over a mile away.
Disadvantages
Since Wildmutt sees through smelling and hearing, he is vulnerable to loud noises or strong smells. He is also useless when his nostrils are clogged. Wildmutt's lack of verbal communication can also be a problem when trying to convey messages, though Gwen seems to understand him well enough.
XLR8
XLR8 (read as "accelerate" wink is a lizard-like alien with lightning-quick reflexes and the ability to reach speeds in excess of 300 mph. His speed power comes from manipulating friction, which allows him to run over almost any surface, including non-solid and slanted ones. XLR8 is weaker than most of the other alien forms, but makes up for it with his speed. XLR8 has trouble in the presence of strong magnetic fields, as they disrupt his nervous system.
Advantages
*Has lightning-quick reflexes.
*Is capable of incredible speed (up to 300 mph).
*Can manipulate friction.
*Is capable of running on most any surface.
*Can roll at high speeds by using the balls under his feet.
*Is a very-quick fighter thanks to the previous benefits.
*Can create localized tornados by running around in a big circle.
Disadvantages
Magnetic-based attacks cause XLR8's nervous system to go haywire. He's also not quite as strong as the other alien forms, though his speed tends to make up for it.
Cannon Bolt
Cannon Bolt is from a species of alien called an "Arburian Pelarota," though they are now mostly (if not completely) extinct as the Great One destroyed their planet roughly a week before Ben discovers the form. He is a hulking, broad-shouldered alien covered in bony armor plating and can roll into a ball like an armadillo. He can then roll into enemies as an attack. He is the only alien so far who is not a part of the original ten.
Advantages
*Has a hard shell that's impervious to attack, and can also reflect energy attacks.
*Can cover himself in his shell and roll-bounce to attack.
*Has enough room within the shell to carry people.
*Can roll-bounce at incredibly fast speeds.
*Can bounce off of walls without losing momentum.
Disadvantages
Cannon Bolt cannot balance very well without going into ball form due to his bulk, high center of gravity, and short limbs.
Wild Vine
Wild Vine first appears in the episode "Camp Fear". Wild Vine is plant-based with six legs, three-fingered claws, and a venus fly trap around his head. He can grow any part of his body fairly quickly, allowing him to stretch his limbs or grow spikes at will. He also has several pods on his back that act as powerful explosives.
Advantages
*Can grow any part of his body at will, allowing him to strect his limbs or grow spikes.
*Has sharp claws.
*Carries explosive seed pods on his back.
Disadvantages
Since he is a plant, Wild Vine is presumably weak against temperature extremes (fire, freezing) and various anti-fungal agents.
Ben is a typical 10-year-old boy - he plays video games, rides his bike, and sometimes gets into some mischief. During a camping trip with his grandfather Max, and his cousin Gwen, he finds the Omnitrix, an alien device that gives him the ability to turn into different aliens.
