[Disclaimer: Not my image, but it fits the character idea perfectly.]

At roughly Five feet tall he's considerably taller than average stallions, and even greater contrast to his own kind who are usually shorter than a mare. Though he looks sleek and smooth, it's actually very short black fur made of an enhanced form of Keratin that's tougher and shined more easily, it often instinctively 'fluffs up' in some circumstances. His mane and tail are made of more jell-like Sea-green strands, a color that is mirrored in his eyes, wings, shell, stomach, and even his tongue.

Otherwise, He lacks the excessive volume of holes that most changelings seem to have, Has a shell along his back to protect his wings, which are comprised of a quartet of longer, sleeker wings compared to his species' norm. His stomach is actually a set of see-through bands of green around his middle, luckily there's no freaky organs visible to gross people out.

While his eyes appear featureless at first, there's a subtle light behind the green layers to hint at where he's looking.

In honorable changeling fashion, as a rogue, he will not speak of any details that can be used to identify or track the hive he originates from, for all intents and purposes acting as if they did not exist... at least, that's his reason for refusing to give any clear information on them.

For himself though? He'll happily claim to be born and bred to make others smile with glee or scream in terror, rebirthed in his old hive to give him advantages while trying to survive 'without' a hive. He has successfully eluded or escaped authorities all around Equestria for Three years and counting, he always seems to find a way to evade or escape restraint, whether physical or magical in nature... and yet, whenever he escapes they just find him again in a new location playing pranks or telling jokes.

Otherwise, he is frustratingly unclear about his actual origins or even solid information on himself or his plans for the future... for all anyone knows, he could be plotting to conquer the kingdom and nobody'd see it coming!

Stealth, Espionage, Infiltration: Such skills are common to changelings as a species, and quite literally a primary source of survival for them for countless generations.

Emotional Recognition and Manipulation: A species that 'lives' off of emotions can easily boast unique skills related to reading emotional beings as well as influencing them, not unlike experienced farmers and their cattle.

Unusual learning potential: It's not precisely a superior learning capability, as it is a different one, a hive-mind, even made up of countless individuals instead of blank drones, learns in different ways from life-long unconnected individuals, not the least of which is the ability to combine the mental capacity of multiple minds over great distances for intellectual pursuits.

Advanced Biological knowledge and Medically applicable Experience: Not 'technically' a medical specialist, but part of imitating another species is knowing how their bodies function, without that any disguise will fail eventually. More importantly, knowledge of a changeling's own biology, as well as it's malleability and how to manipulate it are Required knowledge in the hive. Much of this understanding can be applied in some fashion to learning the biology of new creatures.

Strange Biology: Due to the high abnormal biology of changelings compared to... 'most' species actually, they bear immunity to some things that are common threats to those species, such as lack of oxygen, spells or poisons targeting specific organs or fragile biology, and such, while other's may only be resisted better, such as crushing or over-heating. They also have a somewhat tougher hide than an average pony's with more flexible joints, and a special quality in their hooves for climbing most surfaces, as well as their biology being optimized to work well with both their Shape-shifting and Bio-alchemy, necessary both for imitating other species as well as altering their base form... As a side note, for a changeling, a stomach is more for storage than for dissolving foody things.

-
Refined Buzz-Flight: Though capable of a high level of forward momentum, A changelings wings are especially optimized for rapid changes in direction without sacrificing speed, up to a certain thresh-hold at least, the range of motion narrows with increased momentum. Chryss' wings in particular are refined for far higher speeds than an average changelings, but this makes his wings much louder, like a buzzing hornet, or more draining when magic is applied to boost it.

-
Emotivorous: Changelings do not subsist on solid foods like other species, though they 'can' eat and enjoy them, and can stave off the 'feeling' of starvation for a while with it. Their primary Dietary Requirement though, is Emotional energy, put off naturally by other species who 'feel' things, which is used to power their bodily functions, magic, and even higher brain-functions... Starvation is not pretty, food poisoning though... depends on the food.

-
Bio-Alchemy: Not quite shape-shifting, so much as Biological manipulation, their Body-mass is specially crafted to be influenced by the art of Bio-Alchemy, letting them tweak their base forms in a variety of ways, but it is far slower, more costly, and above all more 'permanent' than shape-shifting is, but has been used since their origins to ensure that each generation had a higher chance of survival than the last. It uses a variety of special reagents and facilities though, so it is not prudent to use in places that aren't a more permanent structure.

-
Changeling Senses: As a changeling, one of the primary sensory differences from other species is inherently available empathy, every changeling can feel, and indeed 'taste', the emotions of other creatures. Their more common senses are more protected than others, such as the screens over their eyes allowing them less disruption from dust and debris, while they can 'shift-away' their nostrils or mouth to avoid gases or smells. In particular, they are refined to see well in the poor lighting of hives and to recognize scents that could either be signals, or evidence of intruders.

Shape-shifting: A Changelings Primary tool of survival, concealing their natural appearance to blend in with their prey, able to take on the form of nearly any creature of 'near' size with minimal cost to their mana and negligible upkeep once applied, they can push it farther for greater cost. It can be used to alter their insides to imitate other species as well, for greater integrity of disguises, though it is always characterized by a colorful flash of fire=like magic, and can be disrupted by sufficient trauma to the head or mind in particular, but great enough trauma to the body can disrupt it eventually as well. On it's own it's not too great a boon in combat aside from disguises, but it can be used to tweak the body's other capabilities so long as disruption is avoided.

-
Hive-link: Arguably one of the greater powers of changelings as a whole, the Hive-link connects all the minds of the hive in a sort of Hive-scape, allowing them mental possibilities that other species simply don't have. The most prevalent being communication, a hive is always greater than the sum of it's parts, a changeling can broadcast things to anyone else in the hive, allowing the sharing of information, sensory data, ideas, and so on, though experience can only be shared in-part as physical practice cannot be handed of. It is also used to create forums of interaction, allowing many minds to share their mental capacity towards intellectual pursuits, such as research or analysis. In a way, it can also provide an escape from physical or mental trauma, allowing a changeling to escape from various forms of torture or crippling pain by dispersing it.

-
Combat-Shifting: A more intensified application of Shape-shifting, additional mana allows for more solidified transformations, which while they don't require up-keep once completed, are not as fluid or well integrated as Bio-alchemical changes, so while it can be used to make armor, it's usually less refined in 'some' way, similar for weapons it can make. Often Combat shifts are specialized in one way and inferior in others. It can also be used for some internal things, such as thickening the hide, or producing venom glands. While these changes aren't 'disrupted' in the same way as normal shape-shifting, they can be 'broken' in a more literal sense, which carries potential back-fire for the user.

-
Magic: Magic! What a wonderful thing! Flexible, Variable, Dangerous or helpful! It can fulfill so many purposes!... But only if you know how to make it perform a certain way, and have the power necessary to carry it out. For changelings, magic is less difficult to learn new methods than other species, with the benefit of the hive-link to share data and teachings, a Changeling can learn a new spell from another's memory in record time, and easily develop and impressive repertoire, though given their dependency on the same power to 'live' they can also burn extra to enhance their body or enhance other natural functions... The catch? Over-using magic can prove more fatal than for ponies, their magic is powers by their internal energy, which is also what keeps their body's healthy and maintains higher brain functions. Even more so, it is what keeps the 'hive' healthy and functioning, and no changeling should be willing to sacrifice the hive for a mere power-boost... supposedly.

-
Illusions: Chryss's specialty in particular, He has spent a great deal of time practicing with illusion magic, using it to entertain or terrify ponies into giving him tasty snacks. It has countless uses for the experienced, from befuddling an enemy, to entertaining an ally, Making a fancy entrance, or simply confusing people in general. His preffered combat style, when forced to, is using illusions to make the enemy paranoid and make it impossible to tell which 'attack' is imaginary or real, great for escapes or getting at weak-spots.

Big surprise, changelings don't carry much equipment XD They do however often carry a few unique little tools around, small enough to swallow.

Lock-picking set, water-proof of course.

3 x Builder Drone eggs

Born and raised in Tijuana, Mexico, Escotto is the youngest of Los Hermanos De Las Rochas (The Brothers De Las Rochas). The brothers' town was under the mercy of a powerful drug cartel whose son attended school with them. While everyone wallowed in fear, and turned to God for asylum, Escotto turned to a Chinese guy he once saw running on water and punch a tree into firewood.

At Escotto's urging, the man told Escotto about the concept of Qi, Chinese martial arts, and Buddhism. Seeing what they could do about the Cartel problem, Escotto asked the man to teach him and his brother martial arts. At first the man refused to teach them, since they weren't Chinese. Antonio refused to learn, convinced the man was a satanist. However, three months of annoying both this man and Antonio caused them to cave in.

By the time Escotto turned 13, the son of the Drug Cartel leader killed his father inherited his position as the new leader and kidnapped a “lady friend” of Antonio's. One kick ass action plot that ended with the Drug Cartel dead or fleeing later, Los Hermanos De Las Rochas learned their master was part of Chún Shàolín (“Pure Shàolín”): An underground group of martial artists whose purpose was to preserve the teachings of Shaolin, and one day overthrow the communists in China. Having learned all they could, the brothers where brought to China for the “Trials of the Thirty-Six Chambers”. Upon being first to completing the chambers, Escotto was given a scroll, and his brother a set of prayer beads.

Opening this scroll transmitted the lost techniques of Shàolín. Thus, it was time for the brothers to take their place as the champions of Shaolin and spread the Dharma t-

“Wait, does this mean I have to shave my head and never get laid?”

“But, of course.”

“Haha, no. I'll stick to being a Gong-Fu badass. But hey, call me up when you're ready to kick the commies out!”

…. Or, rather they returned to Mexico, got a scholarship to attend college in California, where Escotto learned to skate and trolls the hell out of people.

Escotto's powers focus more on enhancing and/or augmenting his physical abilities. Certain abilities work better with certain techniques and styles.

Xīngyǐng yuán wǔ (Star Shadow Dance): A technique of the Wing Chun branch. The user's conjures tangible after-images that imitates their movements a split-second afterward. This allows them to bury their target under a flurry of blows, confuse their opponents with multiple images of them, or in Escotto's case, engage multiple enemies at once if used properly

Wǔ Xiàng (Five Symbols): A technique of the Hung Gar branch. The user assumes a stance imitating one of the Five Symbols of the Big Dipper constellation. The Qīnglóng (Blue-Green Dragon) Stance gives the user's strikes a venomous property, but on the flip side can be used to cure poisons. The Zhū Què (Vermilion Bird) Stance allows the user to move at incredible speeds to the point of seeming to teleport.

The Bái Hǔ (White Tiger) Stance gives the user's strikes a slashing property that can rend various materials. Xuánwǔ (Black Tortoise/Mysterious Warrior) Stance allows the user to absorb the force of strikes successfully parried and turn it back on the opponent, regardless of their size, strength, etc.

Finally, the Huánglóng (Golden Dragon) Stance grants the user similar abilities of the previous for stands. These include: Phasing through matter, applying a “Soul Burn” effect to those they hit, teleporting short distances, and his skin turning into dragon scales that can withstand most damage. However, each stance's effect can only be used if the user continuously imitates that animal. If their stance is broken or interrupted, the effects are canceled. The Huánglóng stance is only usable if the user fells five opponents with each the previous four, and it's effects only last 20 minutes.

Yújiā Yánshēn (Yogi's Reach): A technique of the Choy li Fut branch. The user is able to increase the flexibility of their body. This allows them to extend their limbs an extra 50 feet, give their strikes the properties of a whip and/or ensnare targets. Escotto uses his technique to achieve some ridiculous forms

Fēngshuǐ zhī nù (Fenshi's Fury): A technique of the Northern Shaolin branch. The user is able to move the very air, sending gusts with their punches and kicks, creating tornados with spinning movements, and can step on the air as if it were solid. While seemingly redundant, Escotto uses this as an alternative to Yújiā Yánshēn

Zuìjiǔ fènnù (Drunken Rage): Not a power, but a fact about Escotto. When he drinks, he goes into a sort of drunken rage. His strikes are much faster, stronger and his pain receptors are numbed. This effect lasts about five minutes, but extends every time Escotto finishes a full bottle of alcohol. However, his behavior becomes unpredictable. It's also the only way Escotto can remember his Drunken Boxing. When the five minutes are up, Escotto passes out for eight hours and wakes up with a horrible hang over. As such, he saves this for particularly difficult opponents.

Some notes on Escotto's powers: Escotto can only employ one of these abilities at a time. Each ability lasts until Escotto's Qi is spent, or until it's dismissed, canceled, interrupted, etc. The way I'll manage Escotto's Qi is that each post that has him use one of these abilities will count as one use of his Qi. Escotto will get... Let's say 20 uses of Qi and can replenish them by doing Qigong or meditation exercises. The only exception will be his Drunken Rage.
