The Great Sandcastles.

Prestixx removes the stone on top of and in front of the Iron Wolf and switches back into his normal body.
"The matoran are looking at you weird," he comments.

Timeskip to them getting out of Atero?

The tank rolls out of Ov-Metru into the Deadman's Desert.

This area is seized by RMS.

A couple of off-duty RMS are relaxing on the castle walls, sharing drinks with little umbrellas in them.

"Hey, you, up there. I'm gonna have to ask you to git. No Toa allowed or something."

Taken by surprise they jump up and flip out their Stone Launchers. "Freeze, Toa!"

While the RMS are trying to deal with the cold by applying Ice Resistance to themselves, "Shredder" take his shots from a hidden position. A bolt of solid air pierces both of their helmets and they drop down.

Tredixs grabs the new troops in the area with Magnetism and holds them in front of the barrels/place where ammo/energies would be shot out from, both for the ones in Tredixs' area and the ones around "Shredder's" hiding spot. 

"How willing are you to kill your own men? Because I will slaughter thousands times more, so get used to it."

Tredixs keeps the soldiers held there, fighting the tanks's control without much effort.
