Undyne x Avery

Avery, she never had a last name, she was killed in the war between monster and human. She was attempted to be brought back to life but nothing worked, that's what they thought. Until her body went missing, Avery has been alive through all the generations, she's part Ghost part wolf part human. She was the child of the first monster human relationship before the war, she was hunted and killed, her name is in every monster history book. Now she walks the earth in her human form by day, and Ghost by night.
