Early Life Edit
Physical Appearance Edit
Light brown skin, black eyes, and a bald head.
Aldon seemed to be more empathetic and sympathetic towards the mermaids as it caused Donna intense pain, much unlike his colleagues, who see them as nothing more than test subjects. But when Donna manages to escape, he becomes detached and more concerned with the task at hand.
Towards the end of his life, Decker becomes obsessed with getting closer to Donna due to being under the influence of the siren song. He abandons his science practices as he desperately seeks out the mermaid. However, Decker becomes heartbroken when he learns that Donna only used the siren song on him to get away from him, which crushes Aldon’s dreams of being with the mermaid he believed to love and vice versa. The pain becomes too much for him and becomes suicidal; Decker takes his life because of this pain.
