In children's programming, the dreaded d-word (death) and k-word (kill) are often replaced with words like destroy or the character's are simply cut off. Actually showing this is an even bigger issue, which leads to the character in question being sent to an alternate dimension -- or something similar.
Power Rangers, however, is one of the few children's shows to be allowed to consistently kill off characters. Even if some of them are brought back to life.
This list shows any and all human-like characters that were killed off at some point on the show.
-Troy Larson, brother of recurring Space character, Silvy.
-Terrence "Smitty" Smith, human form of Dino Thunder villain, Zeltrax.
