Zeleri saw his ascension to power as a sort of inevitability. He was born a weak, low-class Saiyan boy. Even back then, he knew he was brilliant, and that his brilliance would carry him to greatness. There was never any doubt in his mind, and all of his choices were simply a series of logical, pragmatic steps towards his eventual goal.

He studied biology at the best school his parents could afford to send him to. Even the most advanced classes that they provided proved unchallenging to the young prodigy, and he passed all of them with unprecedented grades.

As a result, some of the most prestigious colleges on Planet Sadla offered him scholarships. He accepted (IDK put the name of the school here), and once again, proved to be an exceptional student.

He was temporarily drafted into the Sadla Defense Force, where he served as a combat medic for half a decade.

Then, he worked in a lab for several years, studying Saiyan genetics. He took a particular interest in Saiyan evolution, although he found that there was a rather large gap in his species evolutionary history that he simply could not account for. Still, he made several large breakthroughs in the field of genetics, which granted him his final promotion.

Zeleri was invited to be the Saiyan King's chief doctor, his most trusted advisor on all medical matters, and personal doctor to the King, his family, and other high-class Saiyans. Zeleri was pleased, but he wasn't surprised. He had earned this. It was where he belonged.

Zeleri was a tall Saiyan, fairly thin, but fit and middle-aged. His face was narrow and his hair was long, tied back in a ponytail. He wore a long black robe covered by a suit of standard Battle Armor.

"This is a routine medical procedure," Zeleri said. Cabba nodded absentmindedly. "I don't expect to find anything wrong with you, but since you've apparently been exposed to beings from another universe, I'm obligated to check you for diseases. Please, stick out your arm."

Cabba did as instructed. His body felt strangely light. It'd been almost a day since the tournament, and yet, his body hadn't adjusted to peacetime. He still felt the hot rush of combat surging through him.

Zeleri thrust a syringe into his arm, drawing blood and removing it before Cabba could even register the negligible pain.

"I'll have this taken to the lab, but I don't expect anything to come of it."

Zeleri scratched something down on his clipboard.

"Now, have you been experiencing any symptoms during or after the tournament? Anything that wouldn't be the result of combat, I mean."

Cabba shook his head. Zeleri made another note.

"Now, did you sustain any injuries during combat?"

Cabba removed his Battle Armor, and then his undershirt. His entire torso was covered in burns, bruises, and cuts. He felt an unusual sense of pride as Zeleri examined his wounds. Yet, at the same time, he felt ashamed. He always thought he was strong enough, and in the past, he always had been. His power had allowed him to save the innocent and protect his planet, and once, that had been satisfactory. But after he saw Vegeta, he realized how much farther he should've pushed himself.

"Your injuries may look fairly severe, but they're superficial for the most part, and all treatable."

Zeleri bandaged over Cabba's entire chest, to prevent any further bleeding or infection.

"They'll go away within a few weeks. If they worsen, notify me immediately. Now, any psychological symptoms?"

"No."

Zeleri wrote another note on his pad.

"I don't expect you to understand how exhilarating the news of a neighboring universe is to a scientist like me. You said in your report that you encountered Saiyans from another universe? I'd like to hear more about them, if you don't mind indulging me. Your report was devoid of specifics."

"Sure," Cabba said, redressing himself. "They were pretty similar to the Saiyans here. The only difference is that they were way stronger than anyone I've ever seen."

"Hm, alright," Zeleri said. "Did you notice any anatomical or psychological differences? Even cultural differences are relevant to my research."

"They seemed pretty…" Cabba took a moment to gather his words. "They seemed to really enjoy fighting. And...they said something about tails. One of them asked why I didn't have one."

Zeleri tapped his pen against his clipboard.

"So you're saying they had tails?"

Cabba shook his head. "No, or at least, I didn't see them. But he seemed surprised that I didn't have one."

"Is that all?"

"I think so."

"This will require further study, but I appreciate the information that you've given me. If you encounter these alternate Saiyans again, I humbly request that you use that opportunity to gather more information for my research."

"I'll try," Cabba said, although he was certain that he'd have other priorities if he encountered Vegeta again.

"Well, actually, there was something else about them, something that isn't on the record."

"Hm?"

"They had the power to transform, and increase their power."

"Can you tell me about their transformations?"

"I can do more than that, I can show you."

Cabba's upper back buzzed with a hot, tingling sensation, like sparks erupting just underneath his skin. His hair turned gold, and floated as if he was underwater, and his entire body radiated with a golden aura. Zeleri could feel his power, simply by standing near him.

"In that case, I'd like to ask you some more questions.."

"Point out any errors if you hear them," Zeleri said, going over his notes. "This form is referred to as 'Super Saiyan.' You achieved this transformation through intense anger, causing your power to multiply. However, after using the form once, you are now able to trigger it at will, without the need for an emotional trigger. Is that all correct?"

"Mhm," Cabba said. "I just sort of...concentrate all my energy into my upper back."

"Well, I know I've already kept you long enough, but I'd like to perform one last test."

Cabba was placed inside a large metal cylinder with a small window, the only thing keeping him from being in complete darkness. Zeleri had taken him from the medical exam room to his laboratory. His laboratory was a cold, sterile, featureless room, with dozens of machines of unknown function.

"This machine will monitor and record your energy as you transform," Zeleri said, his voice audible, even through the thick layer of metal that stood between them.

"Start by powering up normally, without transforming, so we can establish a baseline."

Cabba tightened his muscles, concentrating his energy and flooding himself with power. A hazy white aura built up around his body, that quickly solidified into a pale burning presence. His machine buzzed and hummed as it spat out a paper containing the relevant data.

"Alright, now, transform." Zeleri said.

Cabba's body surged with golden light. The machine buckled and hissed, producing a slip of paper before overheating and shutting down. The numbers were staggering, the energy Cabba produced was comparable to that of a supernova. Zeleri checked the data several times, to make sure that he was seeing correctly. These numbers couldn't possibly be right, and yet, nothing less like that could cause his machine to break.

"Sorry," Cabba said, as he returned to his base form and stumbled out of the steaming chamber.

"Oh, no, it's alright. I was using an old model, it was bound to break eventually. This is an ideal excuse for me to upgrade."

"Alright, thanks," Cabba said. "Do you have all the information you need?"

Zeleri nodded. "I have more than enough."
