Early Life Edit


Physical Appearance Edit


Personality Edit

Admiral Harrison is a no-nonsense type of soldier. He is willing to get his job done and grows irritated quick when others do not follow their jobs (in his eyes). Harrison also has little regard for others, especially those different than him. This is evident when the admiral was willing to do whatever it took to extract what he needed from a mermaid’s (Donna) blood with little to no regard as to how it would effect her health.

Throughout the Series Edit

Season 1 Edit


Admiral Harrison's Relationships Edit

Aldon Decker Edit

Admiral Harrison worked as Aldon’s boss in a military facility. They were not close in anyway, but Harrison often prodded Aldon and his work regarding the mermaid, Donna. Harrison treated Aldon as he would treat anyone below him in rank, which frustrated and worsened his professional relationship with Aldon overtime, especially when Donna escapes the military facility. Harrison presses Aldon to look for the mermaid, but they are both unsuccessful in finding her.

Donna Edit

Although Admiral Harrison doesn’t interact with Donna much at all, he was still her enemy. Harrison made Aldon Decker treat Donna like a test subject. The admiral also made Decker and the rest of the scientists torture and experiment on Donna being she was a mermaid. However, the admiral and Donna don’t interact again once she escapes the military facility she was being held hostage in. The admiral is frustrated and angered with his employees when they cannot find Donna again.
