This article is about a/an mecha in Choushinsei Flashman.

Flash Titan (フラッシュタイタン Furasshu Taitan): A tractor-trailer-like backup mecha for the Flashman and the first secondary mecha in Sentai history. Flash Titan is armed with a dual missile launcher that deploys from its engine hood while the cab and trailer can convert into an airship mode.

Titan Boy

Titan Boy (タイタンボーイ Taitan Bōi): Flashman's second robot that transforms from the tractor unit of the Flash Titan. When the command "Flash Turn! Titan Boy!" is given, the "grill" becomes the feet, the engine compartment becomes the chest, the front wheels become the legs, the back wheels become the back, and the doors reveal the arms, with the smokestacks as the shoulders. Titan Boy is armed with the Radial Cutters (ラジアルカッター Rajiaru Kattā), a set of tire like throwing weapons, and the Boy Cannons (ボーイキャノン Bōi Kyanon) in its shoulders. Although smaller and weaker than Flash King, it makes up for it with greater speed and agility.

Great Titan

Great Titan (グレートタイタン Gurēto Taitan): A robot created by the union of the Titan Boy and the trailer unit of the Flash Titan. When the command "Flash Turn! Great Titan!" is given, the rear of the trailer becomes the legs, and the front part reveals the head (which the head becomes a part of the Titan Boy) and arms, as the wind defector swings out to become the chest. Great Titan is too bulky to move on its own and instead is formed to destroy giant opponents with the Titan Nova (タイタンノバ Taitan Noba) energy beam fired from its chest.



  • Flash Titan has a unique position of being classified both as a "second mech" and "boy robo" due to its situation.
  • Flash Titan being a truck was an homage to the Diaclone figure Convoy, who would be rebranded under Hasbro for its Transformers franchise as Optimus Prime. It's ability to combine with its trailer to form a super robot was a trait it shared with a later version called Power Convoy, which was rebranded as a separate Transformers character Ultra Magnus. The design was reused in the Machine Robo franchise as Tough Trailer and Pro Truck Racer.
