Green With Evil (1): Out of Control - S1-E17
Continuity mistake: Up until Green No More in Series 2 (where the Green Ranger powers are destroyed), the Green Ranger's overshield constantly changes between solid-looking metal to flimsy-looking cotton. This is the most obvious difference between the Japanese and US footage.
Continuity mistake: Aaron Viva grabs a slice of pie with his left hand, but the next shot shows him using his right hand.
Continuity mistake: Subterranean Sonic's arms turn blue in one scene when he's talking about politics.
