A little bit about Delphi...
Delphi has an organic AI uploaded into her brain. She's also fast. "Speed of Mind" fast.
Her "Super Computer" in her brain can regulate people's moves. This opponent was so fast and powerful that he was doing a bunch of damage to a ship in a short amount of time.
In this super brain, she can easily store several thousand encyclopedias and execute 500 different types of martial arts. Terrestrial or not. She was able to perform Kryptonian and Thanagarian martial arts.
