The group chat got leaked and now you have been sentenced to death in a Roman wild beast hunt. If you kill the animal, another one will be put in to take its place. You are completely unarmed. Any animal that could eventually kill a human is allowed. (You can’t say something like a fruit fly, for instance.)
I don’t think they even had a jaw, although I could be wrong. But, those radiodont appendages look like they could do some damage.
