Chekov's Gun

The principle that every element introduced in a story should be necessary and used later.
"When it was said in Chapter one that Timmy's hamster used to only eat the tail fur of the Namaqua chameleon found in Southwestern areas of Namib desert. I knew it was Chekov's gun waiting to go off"

Chekov's Dehydration Gun

If something is introduced at the start of a movie/game/TV show/episode that can easily handle the main conflict, chances are that it will never be used for that purpose.

This is named after a massive freak out Schaffrillas Productions had in his "Megamind vs The Doom Syndicate" review after Megamind stops the Go Fish Gang using the Dehydration Gun, but he didn't use it on the titular Doom Syndicate, even though the plot would've been wrapped up much quicker with it.
"The movie never says that the villains' powers are preventing them from being stopped by a simple gun!" "That, sir, is what we call a Chekov's Dehydration Gun."
