Super Sentai may be used as Power Rangers primary  source footage but many differences between the two shows still emerge. Super Sentai usually shows more violent images, matureer storylines. Characters have been known to die. Super Sentai also is not affraid to be  funny at times, even more so than PR. Many situations in Sentai may not be as funny or make as much sense to Americans ( due to the fact the show is from a different culture than our own ) Super Sentai has also been on longer than Power Rangers. With the first thirteen series not even being adapted by Power Rangers ( Power Rangers didn't even exist till after ZuyoRanger, not counting the Bioman piolet).

Power Rangers generarly is more lighthearted and doesn't show overly violent or sexual situations. It maybe isn't quite as mature as Super Sentai is. Of course there is the obvious american footage that is different. As well as some american made characters. Their have been whole Power Rangers seasons that have differed from Super Sentai in season plot. These can mostly be found in the early episodes.

The irony is that Super Sentai actually aims for a lower target audeince than PR has. Japense culture is different than american culture. They don't mind their kids seeing the more mature stuff since they feel it may
learn  the proper way to act in those situations. They don't think of TV has harming children as much as Americans do. They don't really have a problem where children replicate what they see on tv.
