Chris described himself as an introvert. Capricorn noted that they rarely spoke up in online chat. He knew how to use the advanced features of the PHO search function. Further, he was able to work through school materials in a self-directed manner, netting him some form of education.
His personality is occluded, as his constant changing of forms also affects his mind.
Because of the nature of his power, he developed some morbid interests.
He is extremely sensitive about his privacy and boundaries, to the degree of being overly controlling in his civilian life. On the internet, it made him quite adept at sockpuppeting and information hygiene.
Chris has a program set up to duplicate his preferences between different accounts on PHO. He claimed that it was helping them "find out things" regarding an individual or individuals he believed was surveilling him. He also said that the different usernames correspond to physical transformations he underwent. Chris later claimed that the entire thing was a ruse designed to draw out Heart_Shaped_Pupil's snooping tendencies.
Chris has pushed back against Kenzie's constant prying and surveillance, to the point of setting up ruses to catch her in the action. They did get along sometimes, usually when Chris was using indulgence or a similar transformation.
On at least one occasion, he provided a verification image for their account "Curious_Cephalopod" that appeared to be a literal cephalopod. They indicated, falsely, that their transformations followed a known schedule, and that they would be an insect in a few days.
In person, Chris normally looks like a very average kid with brown curly hair and large braces. As he changes between his forms he constantly needs to adjust the braces. With each form, he rotates through a small but permanent change occurs with his body, an addition in one area that causes a subtraction in another.
As Cryptid, Chris used eight core forms each tied to his emotional state with strengths and weaknesses inherent in each of them, which combine with secondary modifiers that add altered characteristics. Further, he can combine traits from different forms into a hybrid form with hybridized abilities.
If Chris doesn't use his whole range of emotional forms, such as trying to stay in one too long, he claims it negatively impacts his psychology and train of thought. These changes can be euphoric in how they affect his mood, he likens it to a narcotic.
His exposure to his own monstrous forms allegedly gives him resistances to horrific mind effecting powers.
He has claimed to have two transformations a day, although on one occasion he has been seen to transform three times in one day.
Humanoid giant with a pot-belly, small head and thick limbs. Has the ability to swallow large objects and re-shape the materials.
A horrible screaming face taller than the average person and twice as wide, completely cheekless. The lower jaw is attached to the rest of the face the way an insect is attached to a thorax. Innumerable legs that look to be made out of pure muscle provide locomotion while a few claw at his face.Something similar called Creeping Anxiety is mentioned by KenzieMad Anxiety might be a combination of Creeping Anxiety and "mad twitchiness".
Perception-focused, with "a fresh set of eyes". Slow but tough; described as an "armadillo with ears like a fennec fox and bigger eyes [...] and claws because its keen". On the same "spectrum" as Multifaceted Interest "but focused more and pulled together tight". Slow but tough, with sharp senses. Vaguely armadillo-like, with large eyes and ears. Can extrude blades composed of bone and steel. 
Victoria remembered this as Dark introspection. Crow-like and coil-shaped with layers of hard, protective feathers and scales.  It has a disconnect between body and mind, allowing resistance to mind-affecting effects.
gnarled and vaguely birdlike, with a free-swinging head as if its neck had been broken; razor-sharp beak and talons 
Used in Mad Anxiety to give the anxiety "motive" rather than being paralysing.
Used in Strained Peace. Lowers stamina and strength, increases speed and durability. Results in "faster reactions and movements in a pinch, like I’m made of elastic bands that are all taut, ready to release, or I’m a gun with a trigger that needs only a light touch to fire."
Probably a synonym for "fear". Kenzie notes that "Anxiety is quick but fragile", but Chris says it's "paralysing" without Mad Twitchiness.
He generally carries around medical supplies(including injectors) along with videogames and a walkmen, which he says were provided by others to ensure any transformation he undergoes is not the last one and to stave off boredom respectively. In actuality, these injectors are his own tinker creation and the cause of his transformations, with the game unit functioning as a Tinker scanner for powers and similar.
In reality, his earliest memories were about fighting off Breed spawns and escaping decontamination, since he was created by Lab Rat as an emergency survival measure at the start of the Gold Morning. Though he did not fully align himself to his progenitor until later - an uncomfortable process, forced on him by imperatives designed into his body, which he eventually escaped from midway through.
By his own admission, he was once involved in involuntary manslaughter. This is most likely a reference to the couple that followed Chris into Lab Rat's lair, only to be killed by the security system.

“One day I change, come apart instead of changing back.” [...] “Didn’t want to use,” Chris was quiet. “I like him more than most of you.” - Excerpt from Pitch 6.5
↑Behind Weld, someone else was ducking into the room. He looked like he was of a height with Kenzie, but given how boys developed slower, he might’ve been a touch older. He had a mess of tousled brown hair that would have been over his eyes if he wasn’t wearing large headphones as a kind of hairband. He had a very flat expression as he walked around the perimeter of the room. His t-shirt was black with a logo I didn’t recognize, his cargo shorts had stuff packed into the pockets, but he mostly looked like a very average kid. Only his old fashioned braces really stood out to me- the kind that made it hard for him to put his lips together. [...] Chris, too. By process of elimination, he’d be the boy roughly Kenzie’s age. - Excerpt from Flare 2.5
↑Where his curly hair was usually pushed back by headphones, so hair was very close to head - Excerpt from Beacon 8.6
↑He opened the kit and drew out a pair of pliers [...] I glanced at Chris. Chris had two sets of pliers in his mouth. He was readjusting his braces. [...] “You can play me eight times,” Chris said, pulling the pliers out of his mouth, “After that they’ll probably catch on.” - Excerpt from Glare 3.4
Tristan explained, “He changes to one, he gets a little taller, a little stronger, a little more sluggish. He changes to another, gets better eyes, ears…”
“Thus the headphones,” Kenzie said.
“…and less responsive in hand-eye coordination to go with it. He tries to balance, but lately it’s been getting worse.” - Excerpt from Glare 3.2
↑ 27.027.1“Your mood seems better,” I said to him.
The smile dropped away. He looked at me and shrugged. “It’s different. I feel more human, mentally and emotionally.”
The change hadn’t seemed to make any difference in how he looked, either. Were the changes subtle?
“I’m not sure I grasped it all,” I told him. “Once you change, it’s…?”
I trailed off.
“It’s like a hit of a drug,” he said. “Focus, surprise, sadness, appreciation, disgust, fear, anger, and then this one.”
“I call this particular flavor of it Wan Indulgence,” he said. He bit down on the chocolate bar, then closed his eyes, clearly enjoying it. He talked with his mouth full, “Can be enjoyment. I’ll feel it more normally for a few days now that I’ve changed.” - Excerpt from Glare 3.3
↑ 28.028.128.228.3“Yeah,” Chris said. “I knew there was a risk I might be useless for the day, putting myself in a state where I just sit around, eat, play games. So I fucked off. I’ll hit anxiety a few times in the next while, but I’ll make it mad twitchiness so there’s some more motive behind it, instead of it being paralyzing. That’ll be fun.” - Shade 4.6
↑The two of them went to plant it, with Chris picking up a fallen tree on the way. [...] Chris had his head turned, and he was using one hand to cram the last few feet of the dead tree into his mouth. [...] Chris had one hand full with the tree, mouth distended with a fat tongue sticking out, apparently to keep the tree from rubbing against his lower row of teeth; his hand served to protect the other teeth.
I was put in mind of the man I’d seen during the broken trigger, who’d had a tree come out the other direction.
Chris laughed, deep and booming, tree digested. He lowered his chin, mouth closed, hands and arms up to protect his face and guard Kenzie. - Excerpt from Glare 3.3
↑Chris, legs embedded in spiky rock, was using both hands to haul what looked like a long, thin rod out of his throat. He’d swallowed the length of the dead tree like a sword-swallower swallowed a blade, and now he was drawing it back out, changed.
Narrower, thinner, smoother, and slick with fluids.
Chris, it seemed, wasn’t just the kind of changer who could adapt his form. He was the kind of changer who gained new sorts of powers while in an alternate form.
He hauled the last of the tree free of his mouth. Fifteen feet long, thicker at the end he had just removed than at the end he held, now that he was turning it around to get it in a position he could wield it. Too long to be a proper club, not quite a rod either. - Excerpt from Glare 3.3
↑He reared back, and he blew. He’d broken down and processed more of the dead tree than what he’d used to condense it into a giant club-staff. He exhaled a cloud of wet sawdust.
↑He swallowed hard, giving me a suspicion about what he was about to do. He spat out a ball of wood pulp and phlegm, and I flew to one side, letting it sail past me.
He began to pick himself up, working his way up the hill, stabbing down to pierce the ground with his half-stick and plant it there like an ice-climber might use a piton. The slope was just a little steeper at the base of the hill, and the water had become rock again, smooth and with the spikes all pointed downward, not good grips.
He swallowed hard, giving me a suspicion about what he was about to do. He spat out a ball of wood pulp and phlegm, and I flew to one side, letting it sail past me.
I was put in mind of Crawler – the changer power, the spitting, the joyful monster. Crawler had laughed too.
Crawler had critically injured me with his acid spit, and that had let Amy get her hands on me the second time.
↑“People are coming through,” Chris said. “If we need it, I’ll be a distraction. I’m quick, I’ll be in and out.” [...] “Yeah,” Tristan said. “We’ll debate it when the time comes. It’s anxiety?”
“Yep. Mad Anxiety.”
“Great,” Tristan said. “It’s not the screaming one, is it?”
“Mad is the screaming one,” Chris said. “I wanted to make an impact and if we need me as a distraction then screaming is good.”
Tristan said something Spanish under his breath and went to his whiteboard. Swear words, if I had to guess. - Excerpt from Shadow 5.1
↑What I saw had to be Chris. I was far away, so I couldn’t see him well, but it had to be him. It was a face, six feet tall, three feet wide, with no cheeks or anything but a spine connecting the top half from the lower half, as if the chin and bottom row of teeth were the ‘head’ of an insect, the rest of the head the thorax. The setup was surrounded by a ring of spider-like legs in varying shapes and sizes. They looked like flesh and not chitin, though, muscular meat with a pronounced ‘elbow’, coming to a pointed tip where it touched the ground or face. He jerked and twitched, large eyes wide, and some of the legs seemed to be more focused on clawing at his own face than on keeping him mobile. I would have said it was like someone dragging his fingernails across his cheeks, but he didn’t have any cheeks.
He screamed at them, and it was the sound of mortal terror. He’d succeeded in getting Love Lost and Nailbiter’s attention, and now huddled at the foot of a building, pulling against it as if he could pull himself through the seam between sidewalk and store. They didn’t seem to know what to make of him. I didn’t blame them. - Excerpt from Shadow 5.3
↑“Yeah, well, I dunno,” Chris said. “I’m going to relax and wait until my vision comes back. If it takes too long or if I run into trouble, I’ve got another change I was wanting to make today. Keen Vigilance. Perception focused. It’ll give me a fresh set of eyes.” - Glare 3.5
Blind rage would be a mistake I think. Sudden Shock is quick…
…Or Keen Vigilance. Slow but tough…
…and I’d be able to see and hear most of what was going on. Heart Shaped Pupil:
Is that the one with all the eyes? Creepy Kid:
That’s Multifaceted Interest. You call yourself a good student? Heart Shaped Pupil:
I am a good student. Interest and vigilance are the same for you. Creepy Kid:
Same range of the spectrum as Vigilance but diff’t. Is open and loose…
…You haven’t seen Vigilance. Same thing but focused more and pulled together tight…
…Think armadillo with ears like a fennec fox and bigger eyes…
…and claws because its keen - Shadow 5.6
↑ Black, feathered, and wholly unintuitive in construction. He had four legs like a crow’s talons, but large and spindly, and his body wrapped in on itself, with thick scale-like plates like the talons that extended around his ‘face’ and front. The actual features weren’t birdlike, but were nestled in the ‘conch’ of his physical form. If he’d been a banana, the eyes, mouth, and useful features would have been on the inside curve, the outside curve facing forward. But he was more of a tight spiral than a banana, confused by the crests and flares of large, glossy black feathers that filled the gaps.
It was only because his eyes were spaced out that he could rotate them and look out to the sides, each eye yellow with a distorted pupil.
The feathers were heavy and hard, I realized, as he blocked one blast from Sidepiece by rearing up and fanning the feathers out.Shadow 5.9
↑ 46.046.1“Strained is a modifier for forms, it goes around the circle with Repressed Anger, Tense Acceptance, Paralyzed Fear, Stifled Disgust, yadda yadda,” Chris said. He took Kenzie’s cloaking device. “All of which are the bases but with faster reactions and movements in a pinch, like I’m made of elastic bands that are all taut, ready to release, or I’m a gun with a trigger that needs only a light touch to fire.”
“That’s not a good thing,” Capricorn said.
“It’s fine. Faster action, lower stamina, lower strength, more durability. Changes the abilities that manifest. Strained Peace doesn’t really have much in the way of special features, so there isn’t a trigger to pull.” - Excerpt from Torch 7.8
↑I was stressed, so I went out last night, went to the middle of nowhere, changed to Quiet Awe. I put on some music and lounged, tried to shut out the world. I spent too long like that, changed back by accident, went straight back to that form. - excerpt from Torch 7.8
“Food. Because I need to fuel up, and my next form is dense. Some meds. Plus my walkman and pocket atari, and some other stuff. I was sorting out my stuff after getting dressed again.”
“Walkman?” Capricorn asked.
“We’re post-end of the world, I’m not going to bring my phone and risk it getting broken or losing it and having someone use it to figure out my secret identity. Fuck, it’s hard to see it now that it’s not on me.”
↑Others were scattered around the room. Some boys were in Chris’ old corner, having found and started up some of his old games. One had been given to Kenzie- it wasn’t a video game player, but a scanner. She would dismantle it later. - Excerpt from Blinding 11.4
↑“Chevalier. Courtesy of one trip Breakthrough made to the Warden’s Headquarters. I had my ‘gaming device’ with me. Stole a scan of the big man.” - Excerpt from Interlude 16.z II
↑“Yeah,” he said, as if I’d said something very heavy, and he’d felt part of that weight. “I feel like I’ve been trying to get a handle on things since I got my powers.”
“For a while now, then? If I can ask?”
“Just under a year ago,” he said. “I think, along with Chris, I’m the rookie here.”
Post-Gold Morning. That helped put things in context.
Chris, too. By process of elimination, he’d be the boy roughly Kenzie’s age. - Excerpt from Flare 2.5
↑Ashley shook her head. She looked the way Victoria had gone. “She hasn’t killed anyone before, if I had to guess.”
↑“He came to me with a form prepared to counter me. And that is, as far as I detected, only one of three levels of deception that boy was putting into practice. You don’t want to tell me that you’re following his suit.” - Excerpt from Gleaming 9.9
↑“Teacher’s out of the running. His thralls all got their brains back. According to a very talkative little kid who insists on sending me updates after we’ve parted ways, Breakthrough -that’s ah, my old team, The Red Queen’s sister- are now fully in.” - Excerpt from Interlude 16.y II
