Gemini 'Gem' Trent (Left) & Siamese 'Sia' Trent (Right)

Lock & Load

Gem (Lock) and Sia (Load) possess unique, but oddly complementary abilities.

Lock's power presents itself as a low-functioning form of technopathy that focuses on creation and, though she'd not care to admit it, warmongering: she is able to take rudimentary resources, such as metal, wire, wood, etc. and craft it expertly into weapons of many functions almost without a second thought. Through this, she is the ultimate combat pragmatist, taking basic components off the battle field and creating a potent tool with which she can triumph over her enemies.

Load, meanwhile, has a separate ability which, while useful in its own right, becomes downright sadistic in tandem with her sister's. Load also possesses a form of technopathy, although one that functions on a higher level than Lock's; Load can hold a weapon or tool in her hands, and instill it with power in order to 'upgrade' the object, directing it to perform its function better, at a higher level, or more efficiently. Load can take a crude shield made from a sheet of metal and survive an RPG, or a roughly-hewn sword and slice through titanium - all she needs is time and energy.

Gem (Lock):
-Builds require resources. Gem only constructs, not creates, so if she doesn't have the raw material, she can't make anything.
-Her builds are only as effective as the material she has allows them to be; refined, plentiful resources will create effective weapons. Crappy materials won't.
-Complex weaponry requires greater amounts of resources, and wider varieties. Weapons are only as complex as Gem's creativity allows her to make them.
-Builds are limited to weaponry only. Gem can't seem to make anything else.
-Builds do not instill innate knowledge on proper usage. No matter what she constructs, Gem is only as effective with it as her training.
-Lock has no power to 'turn off' her ability, and is always seeing ways things can be put together and constructed and mechanized into tools of war. In the field, this is useful; out of it, it can be a little overwhelming.

Sia (Load):
-Upgrades require energy and focus, and take time to ramp up in power.
-Upgrades are lost if Sia loses possession of the item; an upgrade must be constantly fed energy to maintain itself.
-Upgrades require additional energy to manipulate in a specific direction; if Sia wants a shield that is lighter over sturdier, she must focus to push the upgrade that way.
-Upgrades are not unconscious. Sia must intentionally begin an upgrade process.
-Upgrades do not instill innate knowledge on proper usage, unless the upgrade gets advanced to the point of the object being able to use itself. No matter what she upgrades, or what the upgrades do, Sia is only as effective with the object as her training.

Finally, both girls do not gain any extra durability, survivability, strength, stamina, or speed from their abilities, unless they specfically engineer equipment for these uses. They are human, and suffer all the drawbacks of their species.

It was clanking that awoke Sia. Clanking and muttered groans of frustration and more clanking and- Sia rolled over, lifting an arm to check her clock, red LED's glowing harsh. 8:13. Gem had had worse episodes. Sia strained her neck to check the corner of the room where Gem's scrap heap resided. It was less of a heap, now, more of a...mound? Pile? The words still seemed too big. Whatever, it was smaller than it had been when they'd gone to bed. Or at least, when Sia had gone to bed.
"Gem?" Sia said gently, sitting up in bed, carefully prodding her sister. It was important not to startle her in an episode. Who knew what she'd constructed. "What've you been building?"

Gem dropped the scrap that was in her hands and hovered a hand over a pile of odd, near-spherical objects that lay beside her. She picked one up and cradled it in both hands, standing and turning around - Sia could see her eyes were bloodshot, hair greasy and pulled back. Oil marked her face, though Sia couldn't see any cans or containers in the room. How did she always manage that?
"Bombs."
Oh. Good.
"At first explosive!"
Naturally.
"Just plain bada-boom, y'know, bit of gunpowder? But then I saw these," Gem threw her arm behind her and scooped up some metal shavings, "and I thought, what about a dispersal system? Like, a scatter-bomb." Sia nodded along, ignoring her need for coffee. It was best to let Gem talk. "And that got me thinking about dispersal systems in general! SO many different things you can put in a bomb, Si, it's crazy! This one's just the boom, but you've got EMP's, sonics, heat. You just put this there and then that goes around here and then you press this-"

Sia leaped frantically from her bed and nearly tackled Gem in sweeping the bomb from her hands, then fled to the window, flinging it open and tossing the small metal bomb out into the open air beyond. It clicked mid-flight and Sia pushed herself flat to the ground. There was a boom and a rumble and Sia got up, peeking out of the window. There was smoke, and a small piece of metal was vibrating in the wall next to their window, but through the lingering black plume Sia could see small bits of coloured paper fluttering gently in the breeze, starting their fall to the ground.
"Oh, that one was confetti. A celebration-bomb!" Gem said from behind her, cheerful and spacey.
"What were you celebrating?" Sia asked, exerting calm upon herself, turning around to face Gem.
"Well that's for whoever throws it to decide."
Sia tried to respond, but the tannoy crackled to life, and whatever she was about to say was cut off by the icy tones of Rose Wilson, their leader.
"Gemini and Siamese. Attend breakfast. And then the training room."

Sia groaned, rooting through her drawers to find suitable clothing. Gem just grinned.
"Excellent." She said. "I'm starving."

-Their parents have a sense of humour. Whether or not it's good is another question.
