Circuit is a mechanical owl which acts as an information source (like Alpha 5) and calls Captain Logan to send the Time Flyers when needed.
He traveled to the 21st century with the Time Force Rangers to assist them. He was created by Trip; the two are very close, like brothers.
As the Time Force Rangers' technical advisor, Circuit informs them of the weapons at their disposal, and performs diagnostics on their equipment. When he's not on the job, he frequently resides in Trip's backpack. Circuit could not reveal certain events of the future due to his programming but did see the coming storm that occured in the finale. Circuit eventually returned to the year 3000 after the final battle with Ransik. He appeared once more in the Time Force/Wild Force team up, Reinforcements from the Future.
- Circuit's name was originally supposed to be Digit.
- Like Alpha 5, he is very childlike and longs for his friends' love and affection; in Circuit Unsure, he runs away from home after becoming upset that his friends hate him, leading up to the Rangers having to search for him. He also gets captured by Nadira in Short-Circuited too, and is reprogrammed by her to turn against the Rangers and eliminate them (in a similar fashion to Alpha's reprogramming in The Wedding and Robo Knight's reprogramming and dark power infusion in Vrak is Back), only instead of inserting a disc into Circuit's back and infusing him with dark energy he is brainwashed and rewired by Nadira after being kidnapped by her when the Rangers ignore him again. Trip manages to restore him to normal when the Rangers come to Circuit's rescue.
