Cortés

Cortés (コルテス, Korutesu) is Arrancar that was created by the Hōgyoku that Sai Gonso, the president of the Shinigami Research and Development Institute created. Like Wonderweiss Margela he is considered to be a modified Arrancar. Years after being created Cortés decided to leave Seireitei and join a recently reformed Espada but he soon left it because the organization's goal was to destroy the Shinigami and all other spiritual beings. He is currently a member of Sennō where he is partnered up with Mūshin.
