It does depend on the context but you can say "hitsuyou ha nai" or "hitsuyou ha arimasen"
'Anata ha kirei (da/desu)' means "You are pretty."
Casually: あなたが必要だよ (anata ga hitsuyou dayo) Politely: あなたが必要です (anata ga hitsuyou desu)
Anata ga hitsuyou desu. あなたが必要です。
"Anata ha doudesuka" = " how about you"
"Anata no" = your "watashi" = me "Anata no watashi" is most likely to be said when someone is referring to the listener's perception of themself (the speaker). If I said "Anata no watashi WA uso desu", this would mean "You're perception of me is a lie." (or "I'm not really who you think I am.") "uso" = lie
'Anata ha otokomae desu.'
あなたは天才です (Anata ha tensai desu)
oshiri no ana = rectum (but probably said in a different way) anata ha baka= you are a fool
'Anata ha' with rising intonation.
"Anata ha hen desu."
'Anata ha baka janai desu.'
