a 'gundam' is a giant mecha - its a huge number of series of animes, several mangas, and also a large number of toys (and a couple video games). The first gundam series are probably at least as old as you are, or as close as makes no difference. The 'gundam' series, is, if I remember correctly, somewhat responsible for the 'giant mecha' thing entirely.sneeks in, whats a gundam?? (im old 27!!)???
