As you have probably realized this a skin for Minecraft PE does not carry anything positive. He is more suited for situations where you have to prove yourself as a negative character. The red and black colours make your opponents think twice before engaging you in a fight. This is your chance to prove yourself (as the appearance and actions) a strong player who is willing to run any risk for the sake of victory.
