Intro
After quite some time enjoying Gekko's lizard designs, I asked for and received permission to create some lizards of my own in that style. Since several of Gekko's designs involve a male and female pairing, I decided to follow that model and create two lizards in that style.
So... meet Mala and Chrys. Mala's a male. Chrys is a female. Both are here to have a very good time.
I added a couple creative constraints reflecting that these lizards are made-to-order in a lab, and to give myself some clever rules to work around.
•	Sizes are multiples of 5 cm
•	Mass is a multiple of 5 kg
•	Colors are all derived from copper-containing materials, since that forced me to work within a more limited palette. Mala is short for Malachite and Chrys is short for Chrysocolla, which are the respective base colors of those lizards.
Basic Characteristics
Since Gekko's pairings tend to have much more in common than they have apart, there's also plenty in common between these two.
•	Species: Lizard, entertainment line
•	Height: 140 cm (4'7⅛")
•	Mass: 60 kg (132 lb) for Mala, 65 kg (143 lb) for Chrys
•	Pronouns: He/him for Mala, she/her for Chrys
•	Hair: Thick, fleshy "dreadlocks" that could be bound into a ponytail that reaches to between the shoulder blades.
•	Hands: Standard five-fingered humanoid hands.
•	Tail: 120cm long, tapering from thigh-thick at the base to fingertip thick at its base. Fully prehensile. Typically curled up like a chameleon's tail.
•	Feet: T-rex like. Digitigrade stance, with three foretoes and a smaller heel toe.
Colors
Did I make these a bit overly complicated? Perhaps. But they're pretty, darn it.

•	Three dark bands around each upper arm. The top band begins at the armpit. The bottom band ends just above the elbow.
•	Tail stripes form a sort of ruler, similar to the ruler on a map.
–	Tip of the tail is body colored.
–	Ten narrow stripes spaced 2 cm apart (totaling 40cm)
–	Additional wider stripes spaced 10 cm apart along the rest of the tail's length.

Adult Details
Kink & BDSM Preferences
These are, quite bluntly, the same as the sort of critters I'd want to have a good time with. After all, if I'm the one special ordering lizards to taste, of course they're going to match my tastes.
•	Usually top, but happy to switch
•	Usually dominant, but happy to switch
•	Brutally sadistic towards masochistic partners, but with absolute respect for their boundaries.
•	Strongly verbally abusive to partners who enjoy degradation, but again with respect for boundaries.
Mala's Junk
Humanoid penis and testicles that would be implausibly large on a human, but are monstrous compared to his small, lithe frame. A few prominent veins to increase that "monstrous" look. Very "fleshy" cock; it has a bit of give even when fully erect, which helps with getting it into partners who might otherwise struggle with its size.
Genital Measurements
•	Flaccid penis: 15 cm long (5⅞"), 10 cm (4") in circumference
•	Erect penis: 35 cm long (13¾"), 20 cm (7⅞") in circumference
•	Balls: Big, but proportional to the penis. About 600 cm³
•	Precum: Excessive. More than enough to lubricate a partner without the need for anything else.
•	Ejaculation: Up to 4 liters and extremely thick, but controllable and subject to partner preference. Typically 500 to 750 mL and slightly thicker than a human's.
•	Foreskin: Notably thick. Can comfortably cover the entire cockhead when erect, but also easily slides down over it.
Explanation
Shockingly enough, I actually thought through why his junk might be that big and what it means for interacting with him.
Mala's flaccid penis is slightly longer and only slightly less girthy than the average erect human penis, while his erection is 2⅔x longer and 1⅔x thicker. The intent is pretty simple: I want something long enough that I'd be deep throating it, while being as thick as I can plausibly handle even if it hurts to take it all. It also means his cocktip is very roughly chest height to him, which is a very fun size to look at, and means that long tongue can comfortably reach his cocktip or into his foreskin.
His balls are, likewise, about 2⅔x the size in each direction of a large human's. Wikipedia gives an upper bound on testicle size as 5x2x3 cm, totaling 30 cm³. A typical male's are about 20 cm³. But since Mala's monstrously big, his are 15 cm long x 5 cm wide x 8 cm deep = 600 cm³
Since ejaculation volume is directly proportional to the volume of the testicles, this means that even a semi-realistic evaluation of his virility would lead to about 600 mL or cum. His balls are 30x more voluminous than an average human's and, if you assume he has twice the cum-per-volume as a human, then you get to 600. But because this is all an exercise in excess, I imagine he could cum far more if prompted, such as if a client chooses to get absolutely covered or perhaps even glued down, as opposed to having at least half a chance of swallowing it.
Chrys's Junk
Chrys's breasts are very big for her size. She'd need three hands to fully cover just one of them. Aerolas are as big as the palm of one of her hands. This is not quite as hyper as Mala's cock, but this is again down to taste. A size like this means her boobs would be a good double handful for a human sized partner, but aren't so massive they constantly get in the way of her doing other things to people.
Between her legs, Chrys has standard humanoid anatomy. She has a larger-than-average clit, but it's not extremely prominent like, say, a hyena's pseudo-penis. Excessively wet when aroused, so as to provide plenty of lubrication and stimulation. And by stimulation, I don't just mean for someone fucking her, but the sights, sounds, and smells that come with it too.
Special Abilities
Mala Only: Attribute Theft Borrowing
This attribute manipulation may or may not be outright theft as Mala is willing to return it to his partners. However, he can freely drain someone's physical characteristics such as height, muscle mass, genital size, masculinity, and so on. The drained attributes could be added to his body or simply stored in some vaguely-defined supernatural place for safekeeping.
Note this does not include directly manipulating any sort of mental characteristics nor metaphysical things such as social status. Though he may be able to do such things with his charisma or by publicly embarrassing someone, he can't just snap his fingers to change those things directly. It's also scene-dependent on whether these are actual physical changes, a hypnotic suggestion, or a shared hallucination.
Chrys Only: Attribute Additions & Changes
In contrast to Mala's ability to subtract things from people, Chrys has the ability to add things to a scenario. This may include changing someone's species, giving herself a penis similar to Mala's, giving someone larger genitals or breasts, creating additional sensations of her choosing, and so on. Aside from species changes, the changes are typically minor; she usually won't make someone into a macro, for instance, instead "only" doubling their size.
These attributes may come from her directly if the scenario warrants her being smaller, more petite, or the like. In most cases, however, they'll just be added from nowhere, so as not to mess with the flow of the scene.
Like with Mala's attribute manipulations, these are (almost) always temporary and limited to the scene in which they occur. It's also scene-dependent on whether these are actual physical changes, a hypnotic suggestion, or a shared hallucination.
Limited Telepathy
Both Mala and Chrys can have a psychic communication with someone, even if they're incapable of verbal communication such as due to a language barrier, a major size difference, or simply having their mouth full. This includes "talking" directly to the person's mind and the person being able to respond in kind. This can be used both to engage in dirty talk and for his partners to invoke a safeword.
The lizards can also read someone's mind. They won't do this without consent (even though they could) but, given permission, both Mala and Chrys are happy to root through someone's mind to figure out what really makes them tick. This includes darker fantasies they daren't mention out loud, or things they might not even consciously realize they're into.
Variable Musk & Grime
By default, these lizards have a mild, natural scent to him, akin to someone who'd taken a shower in the morning and had a long day. The sort of scent where any lingering fragrance of soap or body wash has faded, leaving just the natural aroma of his skin. His skin is clean, smooth, and soft. This is, however, variable on demand.
For musk fetishists, the lizards can produce far more intense scents. If someone wants their crotch and armpits to smell like they've just done a grueling workout on a muggy summer day, that's easy. If someone wants their feet to smell like he's forgotten to change his socks for a month, it's possible. All down to the tastes (well, nose) of the client.
To those who enjoy grime, they can indulge that as well. Things like viscous sweat, toejam, smegma, and the like can be produced within minutes. Often, this is done at a pace such that the person attempting to clean their bodies can't keep up and sees just how futile the efforts are.
It is purely optional, but a special feature that certain people (like this author) enjoy.
Backstory
The story behind these lizards is quite simple: Gekko's labs are capable of creating lizards to order. So these are the kind of things I might order.
Of course, this is inevitably going to mean I'd get far more than I bargained for, given the insatiability of two lizards specifically designed for fucking, as if they were an incubus and succubus who will not be satisfied with anything less than the total sexual exhaustion of their victim client. I'm hoping to write something with them soon™ once I come up with a good concept, or just to go into further self-indulgence about their existence.
