While Rex has found his old friend, Echo, alive on Skako Minor, the Republic heroes find themselves pinned by Wat Tambor’s forces!

Though it took some time, Tech finally disconnects Echo from the Techno Union mainframe. “Rex...I got a big headache,” the clone says with a laugh. As Tambor’s decimator droid closes in, the clones and Anakin look to escape through an air vent in the ceiling.

The last to depart, Wrecker leaves a gift for the Separatists. “I’m putting an end to Tambor’s little science experiment,” he says, tossing detonators onto the system controls. Anakin lifts Wrecker into the vent, and the console goes up in a fiery explosion.

Echo leads the group to the only way out -- a narrow pipe connecting two buildings, with a landing platform on the other side. Below them is a giant nothingness.

But the heroes don’t get far, as Tambor’s security droids surround them. Running out of options, Tech has an idea.

He had recorded the distress call of the native Poletec’s flying creatures, the keeradaks. The clever clone plays the sound, and soon a swarm of the beasts appear. The heroes jump onto their backs and make their escape!

The clones and Anakin return to the Poletec village. When a pursuing droid attacks, the Poletec chief becomes angry, claiming that the Republic brought the war to his world.

Rex agrees, but presents the mechanized Echo as proof that the Techno Union is not neutral. They chose sides, he says, and so must the Poletecs. Meanwhile, Tambor sends reinforcements to recover his “experiment.”

The Separatist droids soon arrive -- and both the Republic and Poletec forces meet them head on! The fighting is intense, but the clones, Anakin, and native soldiers stand their ground.

The battle is far from over, however, as gigantic octuptarra droids appear! Anakin and the clones take them out one by one, sending the towering droids toppling onto the dusty ground. The remaining droids retreat to the Techno Union stronghold.

This defeat angers Tambor. “We must find a way to recoup on our investment,” he says. Meanwhile, the Poletec chief bids farewell to the Jedi, and the Republic heroes begin to board their ship.

But Echo stops his captain for a moment. “Rex, thanks for coming after me,” he says. “That’s what brothers do,” Rex replies. “Hopefully, it’s going to be just like old times.”
