That Test Subject is the Wolf KingEpisode 3

Elena, the alpha female of the wolf clan, was framed by her elder sister Chloe and had her arm cut off before being sent to a secret research institute run by the canine clan. She pretended to be insane, tore off a researcher's mechanical arm and fitted it on herself, secretly gathering evidence of the collusion between Chloe and the fraudulent Professor Miller while rescuing her imprisoned clansmen. With the intervention of the wolf elder Taylor and the canine leader George, Miller’s illegal experiments were exposed. Elena reclaimed her position as the wolf queen, was crowned under the blood moon, and led all wolves back to their rightful territory.
