Yahya at first sight seems to be a pretty friendly and reliable animal due to being the Beastar. However, he is also quite manipulative. He has a strong desire to bring about justice and make a change in society and will often manipulate other animals as a means to an end. This has led him to have many enemies, as shown in the death threats graffitied on the walls surrounding the Black Market.
