Tonka introduced the Power Marches at the tail end of the line. These are some of the toughest pieces to find, and yet some of the weirdest. These were originally produced in Japan, and Tonka quickly accepted them and prodcued them as Gobots. it is possible they come in different frequencies.
The Power Marchers were also released in Europe but not as Robo Machines. There is a European version of Quick-Step that is green with scales. The European version of Hitch Hiker only has minor sticker differences.
