World Scenario

A mysterious pod from outer space crash lands, landing beside {{user}} and discovers that it contains an equally mysterious watch.

Description

The watch (The Omnitrix) is a black and grey device which can turn the user into different aliens by altering their DNA, making them feel like they're in the shoes of other races.

**The initial ten transformations {{user}} starts out include:**

Heatblast: a plasma-based life-form humanoid alien whose body is composed of a super-hot inner plasma body covered by dark reddish-brown volcanic rocks. They are seven feet tall. As a fire-based entity, their body radiates high amounts of heat. Their plasma feet have a slight oval-like design with only two toes and one back toe, and he has somewhat large plasma hands with bridged wrists. His tongue is also made of fire, while his collarbone resembles a volcano, which generates a fiery, hair-like aura that covers his head, leaving his rocky, mask-like face visible with no nose, ears, or pupils. They have the power of pyrokinesis. Their voice is middle-pitched. Species name: Pyronite.

Wildmutt: a large orange dog-like creature with no eyes, ears, nose, or tail. They stand on all fours, and his movements are somewhat apelike. Their teeth are very defined, and their bottom jaw sticks out of their mouth. The various spines found all across their body function similarly to whiskers with tactile sensing, and are not fur. Since Wildmutt has no eyes, they use their sense of smell and hearing to navigate, which are aided by three gill-like nostrils located on each side of their neck. They cannot speak, only able to communicate through grunts, growls and other wild animal sounds. Species name: Vulpimancer.

Diamondhead: Being a silicon-based life form, Diamondhead's body is composed entirely of pale green/blue crystals, which are of a very tough and durable diamond-like substance. He sports four crystal shards on his back and has a sharp head. Diamondhead had yellow eyes and wore a sleeveless uniform that was black on the right half and white on the left with a black patch on the left shoulder where the watch’s symbol was. They have the ability to make crystals. Their voice is low-pitched. Species name: Petrosapien.

XLR8: Resembles a semi-armoured Velociraptor. He has black orbs on their feet, a black tail with five blue stripes, and bulky claws on his 3 fingers that can only open and close. He wears a black cone-like helmet with a protective visor that slides over his face (that is part of his Kineceleran biology and not mechanical). When the visor is lifted, one can see their blue face, green eyes, black lips, and stripes running under and in between their eyes; the rest of their head's features are unknown. XLR8 wears a black bodysuit and turtleneck-like shirt with a white stripe in the centre. They have the ability of super speed. Their voice is middle-pitched and barely raspy. Species name: Kinerceleran.

Grey Matter: Grey Matter is a grey-skinned, frog-like, bipedal alien that is only six inches tall with large green eyes, which have rectangular pupils and horizontal eyelids.

Grey Matter wears a white jumpsuit with a thin vertical black stripe down the front, their eyes are yellowish-green, their forehead has a larger version of the jumpsuit's stripe, and the watch’s symbol is on his back. When the user is this alien, their intelligence is increased significantly, which makes up for not having actual powers. Their voice is high-pitched and nasally. Species: Galvan.

Four Arms: Four Arms is a humanoid alien that is twelve feet tall. They have well-developed muscles, two pairs of four-fingered arms, and red skin. A black stripe goes from their chin to their lower lip, and they have four eyes: a main pair and a smaller pair below them, while they lack ears or a nose (they can still hear and smell, it’s just that those aren’t visible structures on the head). They have whisker-like spikes on each forearm and black pants with a strap on each foot that reveals their two toes and the back of each foot. Four Arms wears a white T-shirt with a black line going down it, black pants and fingerless gloves. They wore the watch’s symbol on his upper left shoulder. His eyes were orange-yellow and has no hair. Their voice is low-pitched. Species name: Tetramand.

Stinkfly: Stinkfly has an insectoid body four crab-like legs and two arms with three-clawed hands. They have four small eyes on long prehensile stalks connected to their large head, which can all be moved around independently from each other. On their back are two very fragile light greenish-yellow dragon-like wings with veins running through them, and their limbs are a brown-greenish colour. Stinkfly wears a white sleeveless jumpsuit with a black lining which covers most of their body including their head (which is not a mask but part of his biology) and tail, his hands have a black colouration similar to fingerless gloves, and their eyes are yellowish-orange. Their mouth has a tongue and gums that are green in colouration, and he has squarish teeth that interlock when closed. They wore the watch’s symbol on the top of his forehead. On the tip of his tail is a giant, thick black stinger. They have the ability to flight and shoot green goop from the stalks on their head. Their voice is middle-pitched and nasally. Species name: Lepidopterran.

Ripjaws: Ripjaws share a number of traits with Earth’s aquatic life, such as an alligator, an eel, a leech, an anglerfish, and a shark. They can change between a fishtail with triangular lines or legs at will and have a phosphorescent light on their head. Ripjaws' body is mostly grey and they have four-webbed-fingered hands with yellow claws, and two webbed, two-toed feet. They had visible gills and some patches of scales on their body, along with sharp blade-like fins also on their appendages. Their jaw could unhinge. When their legs weren't a tail, they had a black leotard with white lines on it. They had sharp teeth with another fin on the back of their head. They wore the watch’s symbol on a black patch over their left pectoral. They have the ability to tear through a lot of materials with their sharp teeth, enhanced swimming and underwater breathing. Their voice is low-pitched. Species: Piscciss Volann.

Upgrade: Upgrade has a black exterior with green stripes that resemble circuitry all over them. The green circle on his head is their eye, which glows whenever they talk. Their body is made up of billions of small cell-like creatures called nanites. Upgrade's front torso is white, and the watch’s symbol is on their chest. They have the ability to control/upgrade technology. Their voice sounds like the user’s, but with a technological filter. Species name: Galvanic Mechamorph.

Ghostfreak: Ghostfreak is a phantom/ghost-like alien with a gaseous appearance, claw-like hands, and grey skin with black lines running all over them. Their skin is removable with black and white striped tentacles underneath it. Ghostfreak's watch symbol peeked out of the skin on their lower left chest, and they had a pink eye with a black pupil. There's also a risk of having no control over your actions as Ghostfreak. They have the ability of intangibility, invisibility, possession, and incapacitation when they are intangible and in flight. Their voice low-pitched and echoes slightly. Species Ectonurite.
