This is a bootleg of the DX RV Robo from the series Explosive Dash Task Force Car Ranger, also known as Power Rangers Turbo in the USA. The domestic name was Turbo Megazord.

The robot can separate to form the 5 individual machines, and includes the Gekisou Sword. This bootleg was missing the Radial Shield, but I have seen others that have included it. The toy comes carded, and sells at flea markets for about $15.

The quality is pretty good for a bootleg, and would make an acceptable substitute until you get the real thing. It is made entirely out of a cheap plastic, but it does everything the original does.

The best way to tell if you have a bootleg version is to look for Bandai copywright information as the bootleg has none.
