Frieza's name is a pun on all things relating to the cold, with family members introduced later following his example. As his name ends in a short "a" vowel (rather than the long "ā" which usually signifies "er" in kana spellings on English words), the character's name is typically spelled with an "a" at the end (as opposed to "Freezer"). However, during FUNimation's dubbing of "Dragon Ball Z", the English writers went with the spelling of "Frieza". This has led to some conjecture over it: U.S. released video games and the English dub use "Frieza", while the Japanese language subtitles on FUNimation's DVDs and the Viz translation of the manga uses "Freeza."
