Tadka- Yaksh or Raksh ?

Tadaka and his sons have shown to be Yaksha but as per Ramayana Tadaka, Maarich and Subahu were Rakshas and Ram killed Tadaka and Subahu and Maarich later turned into a Ram devotee.

Can someone explain.

Tadaka was born a yaksh. She married in a raksh family.

Edited to correct a spelling mistake.

oh.....wow...i always thought tadka was a raksh....

The way they show in Ramayan...she seems to have all the powers associated with the raksh culture...so i guess...she didn't look that ugly as shown in ramayan...since she was a yaksh...

Actually Ramayan showed it correct. When she was creating trouble in Vishwamitra's ashram, she was really ugly.

Initially Tadaka was very beautiful. Her husband Sunda was died because of a curse by sage Agastya. Tadaka and her son Mareech attacked Agastya to take revenge. Agastya cursed them to attain demon-hood. He also cursed Tadaka to become monstrous looking.

in Hindu mythology, she was the wife of Ditya King Sumali and Grandmother of Ravana
