Back at T.C.R.I., the Turtles were getting nervous. The Micro-fission Omni-disintegrator was taking longer and longer to fully charge. This meant Traag had even more time to re-form each time. Leo knew, when dealing with an enraged rock monster of this size, an extra second could mean the difference between life and death.

“Come on! Come on!” Leo pleaded, waiting for the weapon’s power bar to refill.

The last molecule in place, a re-formed Traag angrily thundered toward the Turtles. His gargantuan stony fists were raised high, ready for squashing. Leo’s eyes grew wide. The device was still charging, and Traag was gaining on him with every step. For a moment, it looked like they were about to be crushed into Turtle dust.

Just then, the Micro-fission Omni-disintegrator let out a small beep. Leo once again squeezed the trigger, and a glowing energy pulse shattered Traag into a million tiny pieces that went flying through the air. Leo let out a tiny sigh of relief. For a swordsman who rarely handled firearms, he was getting pretty good at this. He looked down at the weapon’s ever-dimming battery light. “This thing’s running out of juice!” he called out.

“And, guys . . . look!” Mikey said suddenly. Beyond the packs of Kraang-droids, the Turtles could see the portal to Dimension X opening up.

Its array of cosmic lights lit up the force field with an eerie, electric glow.

“Whatever’s coming through the portal is gonna be here soon!” Leo said, knowing they were running out of time.

Just behind him at a nearby computer console, Donnie attempted to hack into the Kraang’s complex system. Meanwhile, Raph and Mikey were dodging blaster fire from the Kraang.

Exhausted, Raph impatiently yelled, “When’s that force field coming down, Donnie?”

“I’m working on it!” Donnie shouted, his fingers rapidly punching in codes. Deciphering alien computer systems was extremely difficult, but trying to do it under fire, lasers whizzing by constantly, made it nearly impossible.

Another barrage of energy bolts came raining down on the Turtles as Traag took form again. Leo looked down at the Micro-fission Omni- disintegrator’s battery screen—it was moving so slowly, it didn’t seem to be recharging at all. Leo looked back up just as the rock monster’s eyes reopened and it roared back to life. Traag was furious. With stone fists swinging, he thrashed through the room on a path of destruction. Leo saw one of Traag’s boulder-sized fists about to come down on his head.

“Not good!” Leo said, rolling away to safety right before—CRASH!—Traag smashed a crater into the floor right where Leo would have been standing.

Suddenly, the weapon beeped on. Leo popped back up onto his feet and disintegrated Traag with an energy beam at point-blank range. Traag was nothing but particles!

Donnie found some good news on his computer. “I think I got it!” he shouted.

The force field dimmed, flickering into nothing. Donnie smiled. With the craziest line of code, and under the harshest battle conditions, he had prevailed! This would go down in hacker history. “Yes!” Donnie celebrated. “All hail me!”

But they were too late. Something massive had already started to come through the portal.

“Uh-oh, guys!” Donnie said, seeing the structure take shape as it materialized into their dimension. They had never seen anything quite like it. It was round like a planet, and so big that it cast a wide shadow from deep space over every square inch of T.C.R.I. Even the Kraang-droids stopped their attack to stare in awe at its majesty.

It was a mechanical monument. A destroyer of worlds. An airship sent from Dimension X. It was the Technodrome!
