Neel Kanth Avatar: Neel Kanth avatar is also a main form of him. Once there was arisen a lot of Vish from the churning of the ocean. Lord Shiva had drunk all the Vish to prevent his beautiful world from the bad effects of Vish. Mata Parvati had stopped the Vish to fall below the neck by putting her palm on his neck. So, this form of him is known as the Neel kanth avatar.
