Nina Tucker is a character in the manga and anime franchise Fullmetal Alchemist. She was a young human girl whose father Shou Tucker turned her into a chimera by fusing her with her pet dog Alexander. She was euthanized soon after this by a serial killer named Scar who also murdered her father in the manga and 2009 anime. Her fate proves to be a significant event in the lives of the series' protagonists Edward Elric and his brother Alphonse as they became good friends with Nina and were crushed over their inability to save her.
In the first Fullmetal Alchemist anime from 2003, Nina's father subsequently turned himself into a chimera while trying to resurrect her.
