Queen Arachnia was the Queen of the Spider People in Tom Paris' holodeck program The Adventures of Captain Proton. Photonic lifeforms mistook the program for reality and believed that they were about to be invaded by Doctor Chaotica. Janeway played the part of Arachnia so she could deactivate Chaotica's lightning shield so Captain Proton could save the day and convince the aliens that the threat was gone.
