Pan jolted and awoke due to having a nightmare of what Ultimate Shenron had said to her family, Bulla's family, and their other friends. She constantly reflected on Ultimate Shenron, saying there may be consequences about summoning him again. Pan knew the Black Star Dragon would be a different type of dragon, but the fact that Ultimate Shenron described the original Shenron as a plaything horrified and disgusted her. The dragon disgusted her so much she couldn't sleep soundly that night.
Pan would get up from her bed and walk out of the mansion alone without anyone monitoring her. Although guilty for leaving her home unattended, Pan needed some time to herself, and this time, sleep wasn't going to cut it. Pan flies over to the Wastelands, where Piccolo trained Gohan as a child. Sighing when remembering the stories Gohan would tell her about his training with Piccolo, Pan would levitate down to the ground and close her eyes. Training with Goten for years, she had to wonder.
How strong has she become?
Pan's physical abilities would grow far faster than any pure-blooded Saiyans, having been born with her father's Potential Unleashed state. Combined with training for 15 years, her growth in strength was beyond that of Goten, although her uncle got much stronger in his own right regardless of having his potential unlocked. Gohan, Videl, Goten, and Pan knew there would be a threat to Earth again, despite having so much peace in nearly 20 years. And what Ultimate Shenron said sent the right message.
Tensing her body, gritting her teeth, and having her rage seethe through her blood, Pan growled as her long hair flashed gold and her eyes turned green-blue. Lightning flashes around her body as the ground shakes violently. Her Ki rises to levels beyond even what she knows as a bright gold aura radiates out of her body. Thinking about Ultimate Shenron's sadistic nature, Pan would roar in rage as she transformed into a Super Saiyan 2, unleashing a pillar of Ki shooting into the sky.
But this isn't an ordinary version of Super Saiyan 2, and this version of Super Saiyan 2 was hundreds of times more potent than the standard version. Her strength, speed, and Ki output massively surpass the Super Saiyan 3 transformation. Gohan was the first to discover this version of Super Saiyan 2 not long after the 28th World Martial Arts Tournament when Goku fought Uub, the human reincarnation of Kid Buu, and Pan would be the second person to discover the overwhelming power she feels.
This transformation is what is known as Potential Unleashed Super Saiyan 2.
Breathing heavily from the massive upsurge in power, Pan would check herself out to see her change in appearance. Her long golden hair is brighter than usual, more lightning strikes around her body, and her aura is far more violent. Pan knew the ordinary Super Saiyan 2 form would multiply her base power by 100x. But using her Potential Unleashed State on top of that form multiplied her physical abilities hundreds of times more. But of course, Gohan knew that he and Pan needed to master Super Saiyan 2 first, like how he and Goku mastered the first Super Saiyan transformation before the Cell Games decades ago, before they could achieve this power.
Before pondering any further, she hears a calm voice her family knows very well.
"Well, that's quite interesting. I didn't think you'd pull something like that off." The voice spoke to Pan.
Pan would turn around instantly to see the God of Destruction, Beerus. Usually, she would be terrified of seeing him without Whis. But after training for 15 years and achieving a far more powerful version of Super Saiyan 2, Pan was no longer fearful of Beerus the Destroyer. Beerus would float to the ground and walk over to Pan, barely towering over her due to Pan's height as an adult. Strangely, Whis was not with Beerus like he usually is.
"You're all grown up now, huh? Nice to see you again, Pan..." Beerus smiled warmly.
"Hi, Beerus. What's something that got you here?" Pan asked.
"Well, as we discussed before, Ultimate Shenron has told you guys about thinking twice before summoning him again. Ultimate Shenron wasn't just trying to scare your pants off. If anything, he warned you guys about great evil being part of those Black Star Dragon Balls." Beerus explains why he's here on Earth.
"A great evil that is part of the Black Star Dragon Balls!? Please tell me you only knew at the last second!" Pan yelled in horror.
"Surprisingly, I did. And that's coming from someone who pays a lot of attention. And that goes for Whis, who knew what Ultimate Shenron meant first." Beerus would scratch his ears like a cat.
"When will we-?" Pan asked before getting cut off.
"Whis will discuss the matter with everyone tomorrow. I know you're an adult, Pan. But you might want to go back to your mansion. You don't want your family to worry about you. Especially how your first summoning with Ultimate Shenron played out." Beerus would begin to float away.
"Wait, what kind of evil are we facing?" Pan asked Beerus.
Beerus would look back and stare down at Pan.
"The Nameless Namekian knew the Earth Dragon Balls hold negative energy when too many wishes get granted in one year. And that negative energy takes physical form and becomes known as The Shadow Dragons. The Shadow Dragons are mighty beings, but since the Earth Dragon Balls have disappeared, you're about to deal with The Black Star Shadow Dragons. As you may have guessed, they are far more powerful than the Earth Shadow Dragons." Beerus would foreshadow the threat.
Pan was stunned and horrified at what she had just heard. Shadow Dragons? Black Star Dragon Ball ones at that? How powerful were the Earth Shadow Dragons? And how much more powerful are the Black Star Shadow Dragons? So many questions ran through her head as she nearly doses off in pure shell-shock before snapping back to reality.
"That's all I can say to you, Pan. Now fly along back to your family's mansion..." Beerus would fly off back to his planet.
