Power Rangers Lightspeed Rescue

The Power Rangers Lightspeed Rescue are (chronologically) the 7th generation of Rangers, preceded by the Lost Galaxy Rangers and succeeded by the Time Force Rangers.

They are the first team of Rangers whose powers aren't of mystic origin and are completely man-made, the Rangers selected by an elite organization for their training, the Rangers being adults with professions in their respective fields, and also the first team that the third rule of the Rangers' Code of Honor doesn't apply to them (the past teams' identities were to be kept secret unless in extreme situations).
