Unnamed photonic lifeforms
List of unnamed photonic lifeforms.

Photonic aliens 
These two photonic aliens - along with the rest of their species - mistakenly believed that the Captain Proton holodeck program was real and were at war with Doctor Chaotica. They assumed Human form, but were taken prisoner by Chaotica and his henchmen. After the second alien was killed by Chaotica, the first one returned to the other beings. He later took Human form again and met with The Doctor, who was posing as the President of Earth. The Doctor convinced the alien that they should join forces to defeat Chaotica. The alien agreed and returned to his realm, termed the fifth dimension by the program, once Chaotica had been defeated. ()
