Introduce strong horse in history and now

Although there were many strong horses in the history, I would like to introduce a strong horses which has familiarity to everybody comparatively.
The name of the horse is "Deep Impact".

Deep Impact dealt with at the comparatively cheap price of 70 million yen.
And this horse owner was shocked by brightness by the eye of this horse and he wanted the horse to become a horse which gives a shock strong against many people. So he attached this name to the horse.
After coming out, the horse repeated successive victories.
Deep Impact earned about 1,500 million yen until he retires from the world of competition .

The present strongest horse is "Orfevre" .
This horse differs from Deep Impact,  Orfevre had so rude temperament when he came out. But it has improved gradually.  Experiencing a race, he had been stabilized mentally. As the result, there are no horses can win against him.
