Cooler Rising

Goku flew across a forest. He looked up and then looked over at Gohan. "Gohan! Did you feel that?" he said suddenly.

"Yeah dad," Gohan said. "It felt--"

"Like a power level," Goku said. "A huge one. Do you know where it is?"

"It doesn't feel like anything on Earth." Gohan paused for a moment. "It can't be on Earth; I can't work out where it is. If it's not on Earth, then where is it?"

"In space," Goku said and then stopped flying. Gohan stopped flying soon after. "Gohan! A power that large in space is much stronger than anything we've faced before!"

"Whose power could it be, dad?" Gohan said.

"I'd say Freeza if he'd discovered another form," Goku said. "But Freeza's been dead for years..." Goku shook his head. "We have to train for this, but I don't want to fight it unless it comes here."

"Then what are we meant to do?"

"We have to get the others...we have to train together; we have to fight this if it comes to Earth."
