"Hmm, here, let me see if I can figure it out, Ben," he says reaching up at Ben. Ben then leaned down Rook can reach the Omnitrix more easily. The revonnahgander then begin to fit with the device. However after a few seconds a small beam shot out and hit Rook, zapping him slightly. "Ow!" He yelled, the beam didn't knock him back, but it did sting greatly even if for just a single split second.
"Rook!" Ben said shocked, "Are you okay?
-Soon a strange sensation begins to fill Rook's being, feeling a bit woozy and wobbly before that subsided, "Uh... I do not feel so hot..." He then looked at Ben, the said, "I'm fine. That was just that was a powerful shock..." He faced Ben who grew had grown bit more, Rook was now only at the top of his abs now in terms of height, the two stared for a moment before walking deeper into the warehouse.
After a minute or two, they were at the corner of the warehouse. "Okay," Ben said, "we need to stop this before-" Ben stopped music sentence as he looked at the watch. The glowing, multicolored parts were once again green. Even though the normally black faceplate was still cyan he checked himself still. "Hey! I think I've stopped growing!"
Rook smiled, "Oh that's a relief... although are you stuck like that?" He pointed to Ben's entire body as if gesturing towards his frame.
Ben thought of it for a moment, then said, "I'm not sure, I guess I am..." Ben was now bigger, around 10 feet or so, as Rook was now looking directly at the middle of his abs, which were now an incredible ten-pack!
Rook looked at his communicator then back to Ben, his body massive and rippling with a multitude of muscles. "Hmm I guess you way beyond what Kevin would define as swole," Rook touched Ben's arm inspecting its rippling features and his physique.
"Hahaha," Ben went, "I guess so!" Ben then flexed his arms in a double bicep pose.
Rook took a moment to pout about what he saw, "Ben you are not... enjoying this are you?" he asked as he watched Ben flex his newly gained muscles.
"A little bit," Ben said, now bouncing his pecs.
Rook flexed with Ben for a moment before the sound of a car pull up followed by a few footsteps. A few men in hazmat suits entered the warehouse to see the two muscle behemoths standing before them. Rook awkwardly waved at them, "Hello gentlemen."
