[OOC][Brainstorming] Intelligent Devices for non-"Lyrical Nanoha" mages

[itsune9tl]

Intelligent Devices for anybody named Misaka: These are the espers who could most use a classic Midchildan-style Intelligent Device analogue, although they also need that "psionics, not magic" customization.
Standby form: customize to the user's preference
Base Weapon form: functional railgun with a magazine but no visible trigger, as described by Black Aeronaut elsewhere
Base Defense: "Electric Shield", as described for Guardian Jupiter
Base Attack: "Plasma Beam"
Powered Attack (that requires the user and Device to attack in concert): "Plasma Zanber" if Bardiche will share the code for that attack; something analogous but obviously different if he won't
Personality: ... er ... um ... suggestions welcome here. Nothing that would overpower what little personalities the Misaka Sisters have developed, but something more than '50s-sci-fi-B-movie-robot.

Standby forms:

Mikoto Misaka: her palmtop computer
Niiko Misaka: ??? (something befitting her (eventual) tomboy personality)
Kokono Misaka: ??? (something befitting her (eventual) girly-girl personality)
Nana Misaka: a Gekota pendant
Rei Misaka: a tasteful and reasonably-expensive-looking bracelet
Mimi Misaka: ???
Misaka Worst: a small guard on the back of a glove, worn on her right hand (vaguely like Bardiche's original form)

After these, the Misaka Sisters will end up with mass-produced models that have a bracelet standby form (based on Rei's but not as fancy looking) - the activation animation has it glow, then run like water past the wrist and into the hand of the Misaka Sister using the Device, there taking its "railgun pistol" form.

Suggestions still welcome for personalities for the Misaka Sisters esper devices. Mass-produced models don't get distinct personalities; these get the '50s-sci-fi-B-movie-robot personalities.

EDIT: Oh, and these should help the Misaka Sisters (and Railgun) form and maintain the ionized bubbles that let them fly. Being extremely precise with their mathematics and able to multithread their calculations, the bubbles should be more aerodynamic than what Railgun and the Sisters can manifest on their own, assisting with maintaining altitude.

For the tomboy, get her a game boy, or similar gaming device.
For the Girly Girl, either a hair/ribbon clip or an ear ring.
For the generics, I'd suggest going with a variation on the Smart Watch.
... or a zipper pull.
As for personalities you could always go with a basic Snark-bot meme
