Doug Swallow (also known as Professor Percival P Poison) is a minor character from Phoenix Wright: Trials and Tribulations. He is the murder victim in the first case, Turnabout Memories. His limited dialogue is voiced by Alex in an average voice with a slightly lower pitch.

Story
Doug Swallow is first shown at the beginning of the case, where he is shown still on the ground with a terrified Phoenix Wright standing over him, insisting he didn't do it. Doug Swallow insists that Phoenix did kill him, to which Phoenix responds that Doug is really bad at being dead. Doug then apologizes and agrees to stop talking.

As the case begins, it is revealed that Doug was dating Dahlia Hawthorne until eight months ago. Dahlia then began dating Phoenix, which may have been a cause of conflict between the two and could provide a motive for Phoenix to kill him. Both Doug and Phoenix were students at Ivy University, though Doug was a fourth-year student in Pharmacology while Phoenix was majoring in art and law on the side.

It is later revealed that Doug Swallow was actually the infamous Professor Percival P Poison himself. In this alter ego, he supposedly wore a great purple overcoat that looks like poison. If you pledged to his Patreon, you could apparently get certain poisons from him.

In the final case of the game, Dahlia Hawthorne reveals that since his death, Doug Swallow has been doing very well in hell. He has been making more poisons than ever, which makes him very popular, and they've added a new circle of hell, "The Poison Circle", just for him.
