I once read a book about a future galactic society in which fights between very dangerous were staged. Some of the aliens were biomanufactured just for the arena. By law, the manufactured creatures were not allowed to be able to reproduce. There were other restrictions of the abilities the creatures were allowed to have. This was to avoid someone building a creature which was formidable that the contest would not be entertaining. It also made sure that if a creature escaped, the authorities would be able to handle it. If I remember correctly, one of the restrictions was it was not allowed to capable of genuine flight.
In one of the companies which made such creatures, someone lied to his superiors about what he was building. He made the creature able to fly. He made the creature smarter than he should - and it was his bad luck that he made the creature smarter than he knew. The creature was smarter than humans - and had all the lethal physicality necessary to compete in the arena. Worst of all, he did something which the author never quite explained - he mad the monster able to reproduce itself. Naturally, the creature escaped from the arena.
I don't remember either the name of the book or the author.
