Fires a relativistic electron beam that sends walls of water hundreds of feet into the air

17 waved his arm, releasing an invisible kiai. Goku braced himself for a blunt impact, but the wave exploded on contact. The heat scorched his skin. But the Super Saiyan wasn't even slightly cowed.

THUDD! The golden warrior's elbow slammed into the teenager's back, sending him spinning downward. Now livid, he clenched his fist. His eyes flashed. A ball of electrons began forming in his palm, compressing to a single glowing point and then suddenly expanding outward under quantum degeneracy pressure. A golden ball of light encompassed his hand. "PHOTON FLASH!"

...

The prince twisted his left boot from side to side, digging it into the dirt to brace his footing ever so slightly. He then flared out his golden aura, increasing its width around his body by several inches and causing it to pulsate even faster than normal. Forming in his own two hands were two spheres of golden light, which glowed so brightly they grabbed the attention of both Trunks and android 18.

"Let's finish this, android." Vegeta grunted, his tensed muscles causing his voice to be much more like a growl.

"PHOTON FLASH!" 17 yelled as his yellow energy wave blasted out from his hand. It was narrow, its densely compacted power deadly.

"FINAL FLASH!" the prince released the power of his strongest beam, which now took considerably less time to charge than when he had used it against Cold several years prior.

The two golden beams met in the center with an enormous clap of thunder and suddenly began to shake the entire area. A large yellow ball of power was coalescing in the middle as the excess energy from the beams shot both up, down, and around the sides trying to circumvent the other's blast and reach the intended target.

...

Goku couldn't sense the release of energy, but he sensed the air immediately in front of the cyborg suddenly turning to plasma. He rolled back and fired a Kamehameha straight into the sky, pushing himself toward the ground with all of his energy. The relativistic electron beam tore past him mere inches away—too close for comfort, but nonetheless he was unaffected.

...

VRUUUUM, sounded the constant rumbling of the two clashing beams.

"Is that all the power you have, android? Surely, if you have limitless energy, you can keep this up indefinitely, right?" the prince goaded as he forced more of his stored energy into the final flash—the resulting impact edging the blast wave closer and closer to 17's position.

"As a matter of fact, Vegeta..." number 17 began to get strangely excited. "…I can!" The cyborg unexpectedly added his left hand to the blast as his supposedly infinite power began to pour forth from it as well—doubling the golden beam's intensity while maintaining the same size.

The concentrated, limitless power of the cyborg's energy beam suddenly pierced through the front of Vegeta's Final Flash. Golden light filled the prince's vision as he stared into the blast like headlights zooming towards him on a dark road. Gritting his teeth, he instinctively created a wall of ki at his feet and sprang to his left. The beam disintegrated his shoulder guard and tore away his cape completely.

...

Vegeta stared silently at 17's blast as it sped past him, close enough for him to spit at it. Apparently, the machine really did have perpetual energy—a stark contrast of brilliant ingenuity compared to the weak absorption types which seemed to be constantly losing even the ki they had stolen from others. Yet even as he watched the yellow stream of photons crash into the sea behind him, the explosion sending walls of water hundreds of feet high into the air, the prince smiled—this was a worthy opponent after all.
