Powers and Abilities

Stem Cells stomach houses a limited function nano-factory, allowing her to produce technological devices and weapons. She can increase her production capacity by ingesting additional smartware, such as her skin-like exoshell (which can only fuel one use of Power Reserve).

(“Smartware” is the substance of which the mechas flesh-like exoderm is composed. It is also used for other internal functions.)

She also possesses an extensive engineering database of all kinds of weapons and technology, particularly those of other top-secret organizations they’ve targeted.

All Project Livewire mecha have the same basic design, giving them a durable body, able to survive significant damage, increasing their reflexes and abilities to superhuman, but not too superhuman, levels, allowing them to alter their physical appearance (such as hair colour/style/length, facial features, etc.), run as fast as a jeep, stick to walls, and replay and share their memory files.

They share a group intranet, which allows them to communicate by thought, and this is their main method of communication with each other.


Stem Cell is a “semi-autonomous, artificially intelligent, limited-nanofunction, humanform mecha construct”, or mecha (the R-word [robot] being considered politically incorrect by the older Livewires), created by the top-secret, quasi-governmental R&D program Project Livewire, based on the technologies used to create the Mannites and SHIELD’s LMD’s.

Project Livewire built ten mecha, six of which were trained and tested at the Project, the other four being left deactivated until they were needed to replace lost members of the team. When a new one is activated it is called Stem Cell, until their body’s smartware is fully differentiated and specialized, and it chooses a name. The mecha have all been programmed to be absolutely loyal to Project Livewire, and to follow the main goal of seeking out and destroying other top-secret, quasi-governmental R&D program, having been provided with a list stating the priority they are to be given.

When the team tech specialist, Homebrew, is killed on a mission, Stem Cell is activated and joins the other four members of the team (Cornfed, Gothic Lolita, Hollowpoint Ninja, and Social Butterfly [the fate of the sixth original member and the other three back-up units is unknown]). She wakes while they’re on a mission against a project using technology derived from the original Human Torch, trying to weaponize it to create Pyronanotech semi-sentient virus.

They infiltrated the project just as the experiment got out of control, and they manage to shut it down with Stem Cells help. Throughout most of this Stem Cell believed that she was dreaming, a neuroform-filter designed to cushion the mind on activation.

She accompanied them on further, less hazardous, missions, sabotaging the work of other projects without being detected. On one such mission they uncovered a link to the “White Whale”, the highest priority target on their list. They stowed away in a container of inert nanofluid that AIM was trading to the White Whale and managed to get on board its rogue SHIELD helicarrier. The White Whale turned out to be a hive mind, commanded by a couple of Nick Fury LMD’s infected with a Hydra nanoware attack virus.

They were detected soon after arrival, and found themselves overwhelmed, as, one by one, they’re destroyed, until Stem Cell was left alone, hiding aboard the enemy vessel. Using the neuroform override the others had told her about, she managed to override the human feelings she had been programmed with, allowing her to control her panic, and she reproduced the Pyronanotech technology they had encountered on her fist mission. These rampaged through the helicarrier, destroying the White Whale.

She managed to hack into the helicarrier and control its descent enough to survive the landing. She then gathered up the remains of her team-mates, with the intention of repairing them.


Initially Stem Cell is overwhelmed by her circumstances, seeming quite shy and intimidated by everything, and generally just does what the others tell her to. They are all created with a mental state defaulting to that of a normal human, but this can be overridden by customizing their neuroform configuration, a hidden feature the projects lead designer included, which can be enabled by them removing their left eyeball, and fiddling with the connections behind it.

Once she did this, she managed to override her fears and anxieties, and becomes more confident in her abilities. Like all the Livewires, she has been programmed to be completely loyal to the Project directives, and would even have to give up her life if it was required for the mission.


“Um. Shouldn’t you be more scared ? I mean, I’m dreaming, aren’t I ? What’s you’re excuse ?”

[Thinking over the group intranet] “So that’s it ?! ’Well, she’s at the bottom of the sea now. oh, darn, too bad. Luckily we’re way too detached to give a crap.‘ You guys really are robots, aren’t you ? That’s right, I thought the ’r-word‘… deal with it.”

“G-Great. I’m a cybernetic k-killing machine. With goosebumps.”

“Quite the heaping portion of difficult work on my plate, huh ? Good thing I’ve jacked my optimism up to near-delusional levels.”

“What should I choose for a new name ? I’m not a newbie ’Stem Cell‘ anymore, after all. I did eat my own smartware flesh. How about ’Autocannibal‘ ? Or ’Nanobelly‘ ? Edgier. ’Technoslut‘ ? Or maybe… ’Debbie‘ ?”

DC Universe History

The Livewires could be developed from the technologies of Professor Ivo, and the rest of their history could remain more or less intact.

Prior to customizing her neuroform configuration, Stem Cell has the Uncertainty Drawback.

Design Notes

Since all the Livewire mechas were created together I’m assuming that some powers, which have been exhibited by multiple members of the team, to be common to all of them (i.e. Running, Cling, Recall).
