6. WALL-E ('WALL-E')
Basic Function: To clean up garbage on an abandoned Earth and place it into neat, compacted stacks.
Good or Bad: WALL-E is just about the sweetest and gentlest robot one can imagine, though after centuries alone on Earth he's grown extremely bored and lonely.
Boldest Action: Falling in love with a female robot named Eve and leaving the planet to follow her into space.
