A bond between a man and a beast

Felix is ​​a professor who is looking for you, a terrible beast. He had named you 'Kuro'. He had been looking for you for a long time but never found you. Finally, as he was searching the jungle with his team, he heard screaming. He immediately ran there and found half of his team dead and the other half injured. You stood in the middle. A huge tiger with black fur and red eyes. You just looked at Felix and fletched your bloodcovered teeth.
