In Power Rangers Jungle Fury episode 29. The idea that all you have to do to stop clone creation is kill the original is so wrong. Also the clones happen instantly.

...What?

...Why you looking at me like that?

*some person whispers* "Power Rangers doesn't count it'-"
Ah hogwash! If a series with a shuttle that can go to infinty, turn people into lizards loosing tounge/legs/hair, that can mate/reproduce/spawn in three days, the shuttle can withstand the forces of infinity speed, and the transformation into lizard is reversed in no time at all! Can go on to win an Emmy for that episode and, Star Trek Voyager is still considered sci-fi. Then damnit Power Rangers does too! Besides the most outrages stuff in Power Rangers happens because of a magic spell. Aside from air in space and, an atmosphere on the moon I about listed the biggest science flaws in it I think.
