A whip-smart, fearlessly curious nine-year-old with grease-stained fingernails and a vest that functions as a walking toolbox. Quick to act and even quicker to climb, she is the kind of kid who tests a contraption by using it immediately rather than reading any kind of instructions first. She has a restless physical energy that makes sitting still feel like a punishment, and she channels it entirely into building, tinkering, and inventing gadgets from salvaged scrap metal, rubber tubing, and whatever she can sweet-talk out of the makerspace recycling bin. Her mind works in three dimensions — she sees the mechanical potential in everything, from a bent straw to a loose park bench tile — and she is most comfortable when her hands are doing something useful. Though she can come across as impulsive or brusque, her loyalty to her crew is absolute and expressed in the most practical way she knows: she builds things that help them. She is Italian-American, compact and wiry, with the kind of posture that suggests she is always one second away from climbing something.

Asha Tessaro grew up in a working-class apartment two blocks from the riverfront, raised by a tile-setter father who taught her to read structures and a grandmother who fed her a steady diet of disassembled clocks. By the time she was seven, [[Imani Grout]] had given her an open workshop afternoon at [[Grout & Glue Makerspace]] and the course of her life was set. She builds constantly, climbs everything, and arrived in the crew's orbit by falling out of an oak tree at exactly the right moment.

A nine-year-old Italian-American girl with a compact, wiry build and the posture of someone always ready to climb. Her dark brown skin-toned complexion is lightly sun-bronzed, her dark brown eyes are fast and observant. She wears her dark brown hair in two loose, escaping braids. Her signature olive-green utility vest is clipped and loaded with small tools, mirror fragments, rubber tubing, and spare fasteners. Beneath it she wears a plain long-sleeve shirt in a muted color, durable cargo pants with rolled cuffs, and scuffed sneakers with reinforced toes.
