I'll always be a fan of the DekaRanger intro. Tokusou Sentai, DekaRanger! SPD, Special Police DekaRanger. Five detectives who fight cool with burning hearts. Their mission, to fight evil. They'll protect the safety of all mankind!
Wo-Oh! Judgement, Kimeru ze! Judgmen, DekaRanger! Tokusou Sentai, DekaRanger!
My fave part is:
1! Emergency! 2! DekaRanger! 3! Action! 4! Perfect! 5! Get on!
