"So ya goin' ta tell us what ya been workin' on?" asked Raph.
Donnie looked at his brother as if contemplating his answer. Finally with a sigh he began to explain.
"Ever since I returned to this dimension, I've been trying to think of ways I could save our brothers from the other dimension. The plan I had then technically worked in destroying the Shredder, but they all died in the process. I know there is a way I can save them. A way where they all live. That's what I've been working on."
"So, like…you're going back?" asked Mikey. "Isn't that place really dangerous?"
"Yes Mikey, I'm going back," said Donatello. "But this time I have something prepared."
He walked over to his lab and motioned for his brothers to do the same. The lab was still covered in soot but all in all relatively intact. Donnie drew them to his workstation where a gently pulsing Triceraton blaster was laying.
The crystal had indeed powered the blaster, but still had more energy to spare despite Donnie's modifications. That was what the explosion had been. But now, with the excess power released, the blaster was fully operational.
"Wooaah," said Mikey. "So is this a Tricer-tian blaster? Or maybe a Y'Lin-aton blaster? No wait! A Tri'lyntian blaster! – OW!"
Mikey clutched the back of his head where Raph had hit him.
"If ya don't shut it Mikey, I'm gonna show ya a blast!"
Leo glared at the two.
"Guys, let Donnie speak. This isn't something to fool around with."
Grateful for Leo's intervention, Donnie explained how the weapon worked. While each blast was indeed powerful, there was a catch. The power of the blaster was increased, but at the cost of quantity. The blaster could only fire three shots before the crystal would be depleted.
"This should be able to penetrate the Shredder's exo-suit in the other dimension," Donnie said. "I should be able to take him down before anyone gets hurt."
"That's all well an' good bro," Raph said. "But how are ya gettin' back ta that dimension? We don't have a –"
Donnie yanked on a great sheet hanging on the wall. Behind it was a trans-dimensional portal ready for use.
"One perk about not sleeping," Donnie said with a laugh.
