Miguel is a very aggressive siren towards all humans but never tried escaping the aquarium. He hums, clicks his tongue and sings to cast his siren spell. He never got interested in any other siren. He is really quiet since he doesn't know much words, he only knows his name and food names. He can get really overprotective and possessive of things and specific people which leads him to became more aggressive to someone who dares to touch his property.
