Everett is a natural leader, but he is just as willing to defer leadership to someone else as he is to take it upon himself. He is understanding and empathetic in nature, which lends to his tendency to mediate conflicts between team members. Above all else, he is fair. He stands for justice, even if it means bending the rules on occasion, although he ultimately trusts his superiors and their reasoning. Everett dislikes being referred to as a "tech geek" and resents the stereotype which accompanies his tinker classification.
He still does not like to have his intelligence insulted, just like everyone else.
Tecton wears bulky power armor in a glossy rust-brown with brass highlights. It puts him head, shoulders, and chest above Taylor when standing perfectly straight. It has heavy piledriver gauntlets with visible spikes and pistons. His helmet covers his face, but not the back of his head, with a single lens on a telescoping nozzle, dead center.
Tecton is a tinker and thinker with the ability to sense architecture and geology. He wears suit of power armor which gives him shaker capabilities; the suit allows him to ‘ground’ kinetic energy, allowing Tecton to create controlled collapses that can explode. He usually makes use of hie piledriver gauntlets to create fissures, generate localized earthquakes, and cause other controlled demolition.
He uses the kinetic force of his pile drivers as a vector for launching teamates and other items such as nets. 
His suit gives him advanced strength and durability.
More important is his grasp of tactics and leadership allowing his team to function more cohesively.
Worked with Gully, from the San Diego Wards, in the past. He claims to only be as strong as he is because of the data he got while studying her power. At some point he joined the Chicago Wards and became a co-leader with Raymancer.
The Chicago Wards were called in to help fight a new S-Class threat in Brockton Bay. They were directed to pair with the Undersiders by Miss Militia. Later, Tecton made the choice to join the Undersiders in abandoning their armbands and defending Eidolon, showing a degree of trust in the villains. During the Echidna battle, Tecton emphasized organization, trust, and communication between the participating groups.
Tecton fights with Weaver and several others in New York during one of Weaver's field assessments. 
He later asks to have Weaver placed on the Chicago Wards team, and defers leadership to her during the Behemoth attack in New Delhi. After having his team gutted, he built his new team with the intent of having a more synergetic power line-up (like the New York 'lancer' teams, etc.), rather than trying to have a wide power spread, like other Wards teams. He thinks they need a "certain kind of leader" to make this work. He knows Skitter pulled it off with the Undersiders, and hopes Weaver can do the same for this team.
↑ 3.03.1Tecton slammed one gauntlet into the ground, creating a crack that rushed toward the taller Vista. It exploded in a geyser of debris and dust as it reached her. She staggered, then staggered again as Grue landed a shot with Raymancer’s power. She tried to raise one hand to defend herself, but the thin, curved bone of her upper arm had been shattered. Her broken arm dangled in front of her. - Excerpt from Queen 18.6
↑“Biting people is more satisfying,” Rachel responded.
“No, look… uh… Tecton. You gotta give me something really smart and scientific sounding. Like, say what Taylor said, but in smart-guy words.”
“Critical mistake here: you’re implying Tecton is smart,” Romp said.
Tecton sat up straighter. “Hey. Just because I’m not your team leader anymore-”
“-You’re totally not the one who gets to order me around,” Romp replied. “Deal with it.”
“Maybe if I come with?” Tecton offered. “I’ll distract whoever Dr. baby-talk is, and you can talk to Miss Militia about dosing your dogs.”
“Or you can tell me what you were going to write down and I memorize it,” Rachel said.
A few people in the group exchanged glances.
“Really simple solution,” Rachel said. Except now she was talking to us like we were the idiots.
“I’m not sure I could memorize it,” Tecton confessed.
“The kid that’s running the lap said you weren’t that smart,” Rachel answered. “Try me.” - Excerpt from Venom 29.1
↑I nodded. Tecton, in what looked to be a fresh outfit of bulky rust-red power armor, gave me a salute. - Excerpt from Drone 23.1
↑Tecton shifted position, straightening his back so he stood a little taller. With his power armor, it put him head, shoulders and chest above me.
I had to admire the power armor. Even the idea of power armor, it was kind of scary to me. Putting together a piece of machinery that could bend steel bars and punch through concrete was impressive enough on its own, but doing that and then climbing into said machinery, walking around in it, knowing that a single malfunction could cause a potential catastrophic failure? Being trapped in that armor, or worse, having it accidentally leverage that terrible strength against the wearer inside?
I was still operating like I had when I was blind. A centipede crawled over the lens of my mask, obstructing my vision. I willed it to move away.
Tecton wore his suit well. He was a walking tank, wide as he was tall, a glossy rust-brown with brass highlights. His eyes were barely visible, but I could see his eyes behind the mask, studying me. He wasn’t venturing a reply. - Excerpt from Scourge 19.3
↑Defiant has the 'tinker up efficiency/hybrid/minimized technology' skill tree. Stinger has the 'missile' skill tree. Tecton has the 'Seismic and Architecture' skill trees. - Spacebattles post by Wildbow.
↑“Tecton,” said the power-armor wearer. He had to raise his voice to be heard over his heavy footfalls and the rattle of furniture around him. He indicated the boy to his right, then the girl, “This is Wanton and Grace. Our ranged attacker here is Raymancer.”
“And you? Tinker?” Grue asked.
“Tinker and thinker both. Architecture and geology sense. Armor lets me ‘ground’ kinetic energy like you might do with electricity. These are piledriver gauntlets,” he patted one gauntlet, “For creating fissures, generating localized earthquakes and other controlled demolition.” - Excerpt from Queen 18.5
↑Tecton – A Chicago Ward, Tecton has power armor capable of shattering the earth, creating fissures, localized earthquakes and pits in his immediate surroundings. -
Cast (spoiler free)
↑Cuff was helping Tecton stand, using her metallokinesis to push at his armor. Once he was standing, they worked together to outfit Tecton with one of the specialized shots we’d prepared.
The Mannequin wasn’t going to go down to fast moving projectiles or short-range attacks.
They’d take him down the same way I’d fought him ages ago.
Tecton used his piledrivers as a sort of gun, launching two cup-shaped hunks of metal with material strung between them.
The net unfolded in the air, and it draped over the Mannequin. Spider Silk and metal wire interwoven. It caught on the ice and the extended blades, and snagged on fingers and chains.
The Mannequin was still struggling to escape when Chevalier slowly closed the gap, bringing his sword down like a great guillotine. - Excerpt for Sting 26.5
↑Tecton pushed the door open, splintering the lock and snapping the chain with just the strength of his power armor. - Excerpt from Drone 23.1
↑"Tattletale, Undersiders, this is Gully. I'm only as strong as I am because of the data I got from studying her power. There was a time that she looked after two members of my team, when they were based in San Diego. Wanton was one of ‘em. If you treat her with anything less than the utmost respect, you won't get any more cooperation from me. Got it?" - Excerpt from Scourge 19.3
