Loke

Loke (real name: Leo the Lion) is a supporting protagonist in the anime/manga series ''Fairy Tail. ''Initially introduced as a member of Fairy Tail, he is later revealed to be a Celestial Spirit, specifically the leader of the 12 Zodiac spirits. He was banished from the Celestial world for sending his owner, Karen Lilica to her death, but Lucy Heartfilia helped him gain forgiveness by making the King realise it wasn't his fault(in reality, Karen caused her own death by believing she could summon two spirits at the same time). Afterwards, he gives his key to Lucy and even falls in love with her, which Happy often jokes about much to her chagrin.

He is voiced by Daisuke Kishio in the Japanese version of the anime and Eric Vale in the English version, the latter of whom also voices Trunks.
