Character History


"Upholding the traffic rules of justice! My name is... Signalman!"
―Signalman's roll call[src]

Signalman turned into a child

Signalman is a Space Police officer from the Planet Police, where he left behind his wife Sigue, and his son Sigtaro, to pursue the Universal Reckless Driving Tribe Bowzock. He can sometimes be more of a hindrance than a help to the Carrangers. Because of his intense training in the rules of traffic, he never breaks traffic rules in any case, even if it conflicts with his sense of justice (like in one instance, when Ichitarou Tenma was kidnapped by the Gorotsuki CC Chakkoo, and Signalman gave chase until he came across a red crossing light; while Chakkoo managed to escape. Signalman could not give chase because if he did, he would be breaking a traffic law Tvicon.png TV STORY-Ep. 22: The Tragic Traffic Rule Habit).

Because of his own relations with his son, he has a good friendship with Ichitarou, who he commonly helps with homework (while likewise making sure he goes to school even during the summer) and leaves responsibility of watching his station to. Said station, the Kobaan Base (コバーンベース Kobān Bēsu, Police box Base), is a small Police booth, which can be nearly everywhere in Japan, except places where people might actually pass it. For this reason, Signalman rarely catches any activity, and is usually introduced into most episodes casually observing what is outside his station, stating that no one is around. This is usually before he ends up dragged into an incident involving the Carrangers and/or the Bowzock.

After receiving a letter from his son Sigtarou regarding an upcoming athletics meet on Police, Signalman departs Earth after much debate and deliberation (which was not helped by him having to singlehandedly save the Carrangers after they had been baked into a giant pizza by another Gorotsuki, XX Mileno) Tvicon.png TV STORY-Ep. 27: The Crossroads of Transferring Away From Home..., ultimately choosing to do so due to finally trusting the Carranger enough to leave Earth in their hands. Yet some time after his return, the planet is mysteriously coated in a five-way colored gas (unknowingly distributed by Reckless Dash Emperor Exhaus) which ends up making Sigtarou sick and warps Signalman's mind, making him believe the Carranger were behind it. Deceived, he went back to Earth to take them down for what they've done to Sigtarou and himself while becoming an ally of the Universal Reckless Driving Tribe Bowzock. Fortunately, the Carrangers managed to restore their friend to normal by tricking him into drinking cider after a hard battle with them, which they likewise have him contact to Police to save Sigtarou.

Signalman remains on Earth for the remainder of the series to protect it, and assist the Carranger in stopping the Bowzock and Exhaus's plans, aside from a brief period during New Year's when he brings his wife and son to his station planet for vacation. During Exhaus' final plan, he tries to assist Ichitarou to protect the Carranger during their greatest crisis. He ends up saving the Earth from being blown up by the Bowzock's out-of-control Baribarian when it is sent by the tyrant to destroy the planet and eliminate the minions he had been using all along. After Exhaus' defeat, Signalman returns to Police to partake in a proper education beyond traffic rules and to become a detective.

Ranger Key

The Signalman Ranger Key.

Mobilates' Gokai Change announcement[src]

The Signalman Ranger Key (シグナルマンレンジャーキー Shigunaruman Renjā Kī) is Signalman's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key, along with the other nine extra hero keys and the fifteen sixth ranger keys, were initally acquired by Basco ta Jolokia and later used by the Gokaigers. Like all of his Ranger Keys, Basco used his trumpet, the Rapparatta, to turn the Signalman key into a puppet to do his bidding. Basco united his nine remaining Ranger Keys, the Black Knight key being taken by the Gokaigers before hand, when he was confronted by Goro Hoshino (OhRed†). The Extra Heroes would then fight the Gokaigers again, who wished to take the Ohrangers' greater power rather than just be given it. Signalman fought Don Dogoier (Gokai Green), who fought as OhGreen. The Extra Heroes were taken down by the Olé Bazooka. Signalman's key, along with the rest of the Extra Heroes was claimed by the Gokaiger.

While in the possession of the Gokaigers, the Signalman Ranger Key was used by Don Dogoier (Gokai Green) and Gai Ikari (Gokai Silver) on one occasion each.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Signalman received his key back, restoring him to his normal form.
