About Mugenbine
Mugenbine is a term derived from the words mugen, Japanese for 'infinite', and the English word 'combine', which is the theme for the series. Rather than the traditional shape changing method of previous figures, Mugenbine uses numerous interlocking pegs and sockets to attach and remove components and relocate them in order to form different modes. While all figures have at least two official alternate modes and most have official combinations with one to three other figures, the concept of the line is to allow you to assemble your own animal and machine creations and build your own robots of various size and numbers of sets, an activity encouraged by Bandai to the point where figures with no official combiner modes come with larger head parts to help create your own.
