Aviva is of average height with a runner's physique and long dark hair mixed intermittently with the odd braid and streaks of pink and white.

Normally dressed in a tank top (bearing the pink and white logo of her favorite Sky Hockey team) and rolled-down flight suit, she moves with a purposeful but manic energy.  One look at her tells you she's geared for action rather than contemplation.

One look at her turns out to be difficult, however, because there are two of her.

Staring too intently at the details can tend to give one a headache, but there's definitely two Avivas.  They work always in tandem and when they talk, they tend to alternate back and forth between themselves.  "They" communicate loudly and with wild hand gesticulations punctuated by nonsensical rambling and what sounds like talking backwards.

At times, objects Aviva touches will seem to blink in and out of existence, shimmer briefly, or become doubled.  This does not seem to concern her in the slightest.

Aviva is bubbly, warm, physical, disorienting, and maybe a bit hyper.
