Metrona shares her physical appearance with Tilly Green. She has medium-length black hair, freckles on both sides of her cheek, and has pale yellow skin. Her eyes are oval-shaped, and she also has a bucktooth that is always visible, even with her mouth closed.
She wears a pilot suit: a brown vest, brown cap with goggles, and light brown pants.
Her story is similar to Bixby's: while running the farm, an aphid storm threatened to kill the crops. However, Metrona has something up her sleeve: a biplane crop-duster filled with ladybugs. Releasing the ladybugs above the farm, they ate up the aphids that threatened the farm, saving it once again. ("Family Legacy")
