He was fighting on Dantooine. Which is a dessert like planet. His team of Clone troopers were pushing back countless Super Battledroid. Then out of nowhere a giant ship approaches Mace and his squad. The ship was hovering over the desert then a giant cylinder shaped hammer stomped the ground and cause earthquake like effects and putting a huge whole in the ground. All of his troppers fill into the whole cause it caused a avalanche like effect due to the sand.
Mace used the force to jump hundred of feet into the air only to land right in the middle of atleast 1000 Super battle droids. He used the force to smash away a few layers of droids and had to take some out h2h cause he lost he saber when he jumped out of the crater. The way he took out the droids without his saber was awesome also. He used to force to take out the bolts of a few droids then those droid fell into pieces then he proceeded to use the bolts to throw at some other droids at high vlelocity disabling them in the process. Then he got his saber back and jumped ontop of the ship and disabled it.
I may have left out some stuff but if you watch the cartoon its much cooler than I described. He showed awsome h2h skills and awesome footspeed and handspeed.
Imagine a legendary hero. Someone that defeats entire armies. Someone that literally crushes any and all opposition. Someone that has searched for centuries for a worthy opponent, but found none. Someone that can beat someone at their own game.
Now imagine someone that beats these kind of guys all the time, and you have Jack.
