Card variations

Boulder was released in different ways in different countries. On the european continent, Boulder was released in a BANDAI box and was named "Bolder", in England and the USA on a Tonka card. Generally, the boxed Rock Lords are harder to find. Note the spelling differences "Boulder" and "Bolder". In Japan, Boulder was sold in a special box under the name "Battlerock". In Australia, Boulder was released in a Bandai Box under the "Machine Men" logo, the box differs from the european one: the name is Boulder and not Bolder, the Box shape is different and the logo is not "Gobots" but "Machine Men". The back of the box is also different for series one.

Japan catalogue : Rock Lords series 1

The "Battlerock" Figure released in Japan has a different "skin" tone and helmet color.

The picture on the right, taken from the centerpage photograph of an australian promo comic, shows a prototype of the Boulder figure. Obviously, the Boulder figure was originally planned to be called Granite, while the Granite figure would have been the good leader, and called "Bolder".

The prototype has a slightly different body mould, a darker skin and a different helmet than the final version.
