Can anyone identify these Bionicle sets? Can anyone identify these Lego pieces? They were given to us in a bin of toys, and we cannot identify them. We know they're Lego, and have a 2002 date on them.
Those appear to be Bionicle figures, a theme that was active from 2001 to 2009 (and making a comeback in 2015, I hear). The line focused on buildable "action figures" (aka "constraction figures").
