An alternate spelling of Frieza, one of the main villains in the dragonball series. Both spellings are valid and can be used interchangeably, much like Kakarot.
He is defeated once by the recently super saiyan Goku, and is killed by Trunks at the beginning of the android saga, after being restored and now mostly machine, his father, King Cold is also killed in the same episode.
Freeza was the most powerful being in the universe, until Goku came along and handed his ass to him after transforming into a super saiyan.
Before Planet Vegeta, a saiyan planet, was destroyed, the Galactic Emperor, Freeza took it over, and replaced the universal holiday, Christmas, with a holiday that was completely focused on himself. (Originated from TFS's DBZA series)
A dead drop is a location used to secretly pass items between two people, without requiring them to meet.
Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.
A common place is to duct tape the item to the underside of a toilet cover in a public restroom.
A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."
