Nia Teppelin (ニア・テッペリン, Nia Tepperin?) is the lead female character of the anime and manga series, Tengen Toppa Gurren-Lagann. A mysterious young girl found sleeping in a capsule in the middle of a dump site by Simon, one week after Kamina's death. She had no prior contact with humans, except her father, who is also the sovereign of the Beastmen, the Spiral King. She is very curious, pure and innocent, due to growing up sheltered in a peaceful environment, away from all the battles occurring in the outside world. Despite early misgivings, she is quickly accepted by Team Dai-Gurren, much to the (initial) irking of Yoko. During her journey, she develops a strong empathy towards Simon and grows to be his fiancé.
