Mace enters office, Yoda quickly ignites a green lightsaber, jumps at some random jedi at the bar who are chatting and Yoda jumps right through them. Blood is everywhere, Yoda is now running on the ceiling. Mace lifts off, Yoda shoots down and starts to summersault. Mace clashes into the cannonball with his lightsaber. Sparks fly everywhere, Yoda is beaten out of the way and hits the ground.
Mace is now raging towards Yoda, Yoda suddenly jumps up and rolls through the sky! Mace kicks the green blob to a wall.
Yoda immediately launches back from the wall with his lightsaber pointed towards Mace Windu, on the last moment, Windu twirls to the side while swinging the lightsaber and with the force of Vaapad manages to beat Yoda's lightsaber from his hand, the gay green lightsaber flies out of the window and falls on somebodies head.
Yoda is now crawling backwards and Mace Windu is threatening to kill him, SUDDENLY Yoda flings out force lightning! Mace catches it with his purple lightsaber and lifts it up, now Mace beats it back with a tarzan howl and the lightsaber enters Yoda's body, black smoke is coming from Yoda's chest and his ribs are visible. Yoda is still electrocuting the lightsaber and can't stop now because the lightning makes contact with his body, suddenly in a last attempt to retrieve control over the fight Yoda's mask falls off, the face shown is complete horror.. IT'S KHAAAAAAAN!!!!!! Mace picks up his stuff and quickly dives out of the window. Mace falls on one of the lower levels of Coruscant and his skull shatters in to a thousand pieces, dogs quickly rush in to feed on his brain.
Voila! And there you have it. Mace always beats Yoda but he never survives the pure horror of the alien.
