Sergio-Male,Sergio is an adorable, light-grey furred bat with prominent, upward-curved ears, soft green eyes, and wide, membranous bat wings extending from his arms. He wears a dark grey painter's beret angled gracefully over one ear, a blue hooded tunic sweater, a dark leather apron smudged with dried acrylic paint and pigment spots, and grey fitted trousers with bare, clawed feet. He is rarely seen without his wooden painter's palette, fine brushes, and an easel.

The Spectral Patron-???,A shadowy figure wearing ornate, tattered Spanish colonial velvet attire and a cracked ceramic porcelain mask. Its eyes glow with a dim, phantom light.

Eliana Sergio's Late Wife-Female,A soft, glowing ethereal white bat figure radiating warmth, appearing as a gentle painting come to life in Sergio's moments of deepest despair.
