For now we'll call him P. So P is a humanoid feline-like creature with dense, dark fur that absorbs 90% of light making him incredibly dark. Only his head is a light shade of gray that fades into his chest. He wears armor, looking remarkably similar to Plumber Space Suit except that, there is an Omnitrix on his chest, the red parts are now green, and he has opening in his suit for his gas pipes and the short grey blades he has on each forearm. The Plumber Space Helmet is replaced with a gas mask with pipes that connect into a jetpack on his back. He is 6'2.

-Enhanced Strength -- P has strength that far surpasses human abilities, allowing him to 1000 tons without assistance. However by pushing propane out of his pipes he can lift about 30000 tons as long as a constant flow of propane is being pushed out.

-Enhanced Speed -- P has a running speed that allows his to run at 60 mph. When on all 4 his speed is quadrupled allowing him to run at 240 mph, but with his jetpack, he can boost himself to hypersonic speeds

-Enhanced Reflexes -- P has cat like reflexes allowing him dodge lasers and bullets with mild difficulty

-Forearm Blades -- P has blades on the outside of his forearms allowing him to cut straight throw steel. These blades has microscopic holes on the sharp edges of them that allowing P to inject propane into opponents, ignite his propane, or even blow it out of the edges causing a intense gust of propane to push his enemies back.

-Propane Generation -- P is able to generate his own propane which he uses to breath and can use offensive and defensively. His propane has a slight yellow tint to it.

-Propane Holes -- P has microscopic holes on every limb of his body (fingers, legs, arms, palms, etc.) and he can push propane out these holes, and even ignite it. I'd imagine him making his punches harder by forcing propane out the back of his arm, and being able to attack insanely fast. He can use this to accelerate his movements and attack's, but also to dodge much faster than he could do before.

-Air Suction -- P can create powerful vacuums by reversing the polarity of his holes and sucking in air at immense speeds. He can move about 100 tons of mass with his suction. This can be used offensively and defensively.

-Scramjet/Jetpack -- P has a small box biologically protruding out of his back, with slots at the end. He can force propane at the end allowing him to hover and fly, and when he ignites this propane he can move even faster. When running his suit has protrusions on his shoulders exactly like the one Captain Nemesis has on his suit in Omniverse. These slots open and similar to a Scramjet, the air gets ignited propelling P to 20000mph. They even work underwater, but he can only move at 1000 mph..

-Enhanced Senses -- Being a feline like alien, P is very good in any location. His fur can sense the tiniest of vibration in air, and his nose is very sharp and can smell from incredibly far away. He has superhuman levels of eyesight and can see ants crawling from about 100 feet away. He can chose to see in all wavelengths (infrared, x rays, radios etc.) and can hear conversations from miles away even if people are whispering. His fur allows him to additionally feel the slightest of things touching him, like a mosquito crawling on him; his senses surpass that of a spider. P perceives time incredibly slowly allowing him to make perfect attacks at exactly the right time, and to respond to things moving a hypersonic speeds, like missiles, lasers, and bullets.

-Enhanced Agility -- Along with his enhanced reflexes, P is able to move his body is extremely athletic ways allowing his to perform acrobatic stunts that no human could conceive of doing.

-Extendable Claws -- P has claws on the end of his fingers can retract back under his skin when not is use. These claws are very durable, and sharp, and can do decent amounts of damage, though they only are sharp enough to cut steel. He also has blades on the sides of his forearm similar to the one used by the predator. He can extend these blades out and cover them with propane to inject his enemies. The blades and claws can be charged with solar energy and heated to temperatures comparable to Pyronites.

-Enhanced Durability -- P has smooth but dense skin underneath his fur allowing him to take hits from stronger opponents. His strength is on par with Pyronites, plus his fur is fireproof.

-Bad Swimmer -- In deep water, P will simply sink because his skin is to dense to allow him to swim . However he uses propane to breath and so he doesn't drown.

-Sharp Teeth -- P has sharp teeth that when combined with his powerful jaw muscles can deliver bites on par with tigers. These can also be heated via solar energy.

-Plumber Suit -- P wears a suit similar to the Plumber Space Suit, to completely prevent leaks of propane from exiting the suit. This adds considerable durability to P.

-Master Combatant -- P is one of the greatest fighters in Ben's Arsenal. He freestyles using every martial art from Earth, and some styles from his own planet making Ben unpredictable. Combining his cat like reflexes, agility, and senses with his high pain tolerance, combat skills, durable skin and suit, and his propane enhanced kicks, and punches makes P extremely dangerous on the battlefield.

-High Pain Tolerance -- P has special nerve receptors. He can feel the slightest on touches, but when fighting, special nerve agents numb his pain receptors causing him to not feel punches and kicks. He could get dropped from a building and get back up, and even if he has missing limb he'll keep fighting. He only feels a throbbing sensation in the area of "pain" but this is can be more closely described as a vivid sensation rather than something that hurts.

-Focus -- P develops a intense focus whenever on a mission or is conflict. He rarely speaks unless he has to, and has a deep commanding voice, though he likes working alone. He can fight for hours and won't stop until the threat is dead.

-Brutality -- P is very brutal, and enjoys causing the maximum amount of pain to a being in the shortest amount of time. He breaks and tears off limbs, and impales and blinds his opponents. He always goes for the kill to after hurting his opponent. He punches hard and fast and makes it his mission to break at least, 2 ribs, 1 finger, 2 arms, 1 ankle, plus a hand and a nose, and he must kill his opponent when they are most vulnerable. Did I mention they also are carnivorous and eat the ear of whatever they kill, as they feel that this is the most honorable. He shows no mercy. They respect no one other than their king which is a mutated version of their species who was able to unite their race and form a powerful army to defend their section of the planet from the predators. The only eat beings that have a scratch from their claws on them.

-Enhanced Tactician/Intellect -- P fights hard but also smart. He understands his opponent before fighting and figures out their pressure points allowing him to deal the most amount of damage possible. He understand hard concepts, and has a enhanced memory allowing him to remember any martial art move he sees. He one step above the smartest humans wielding him an IQ of 201.

-Dark Fur/Solar Absorption -- P has dark fur allowing him to blend in with shadows and dark places. He however doesn't have black fur, more like a dark grey. His skin absorbs 80% of light which he uses to get most of his food.

-Energy Shockwave -- P can rapidly expel this energy in a blinding shockwave about 10 meters in all direction, however this is basically throwing away your food so this makes P require "hangry" and fatigued. He stills fights well, but fights much much much more brutally and is eating parts of beings bodies as he fights and biting off necks.

-Energy Weapons -- P can use solar energy to create long and close range weapons/attack's. like blasts, swords, explosives, staffs, and throwables.

-Wind Forcefield -- P can stop and blow back attack by pushing air out of his holes. If he does this all at once, he creates a sort of forcefield that relatively slow objects can't penetrate unless moving fast enough or are heavy enough.

-Prehensile Extendable Tail -- P has a tail which can lift objects under 1 ton. He can crush bones, and steel with this tail and he can whip it around at high speeds to deliver dangerous blows. He can extend his tail increasing it's strength, damage, and range.

-Arm Generation -- P can grow 2 more arms by using solar energy and matter he's eaten, but these arms only have half the physical strength of his normal ones. These are located under his regular ones.

-Ignited Propane -- P can ignite his propane to make fire blasts and enhanced movement/attacks. He can make any part of his body really hot by igniting the holes with propane; limbs can get hot enough to melt Tungsten.

-P's fur is highly conductive for electricity, and if his fur gets stuck, then his senses are decreased

-P's independence and brutality may make him bad for some situations and teamwork. P also can't eat hard matter, or anything poisonous/radioactive without hurting himself.

-P doesn't care about collateral damage. He only focuses on fighting his opponent. He however will not allow babies to be hurt during his battles, since it isn't noble for his kind since he only cares about his opponents.

-Due to the explosive and violent nature of propane. P is a really dangerous alien to use especially near people/structures.
