Combines the multi-form technique with the perfect afterimage to create a thousand clones of himself

"Hah!" Cell grunted, crouching and raising his arms. "As if I'd be fool enough to fight you!"

"What?"

Suddenly beside, beneath, above, and all around Gero's creature, copies began to form. Numerous clones, first in the dozens, and then quickly in the hundreds all started to appear beside Cell.

"Just what the hell is going on?" the prince said, his eyes wide.

"I've done a little extra improving to the multi-form technique, Vegeta—as you can see," the army of Cell snickered, increasing in numbers all the while. "In fact, it's hardly even in the same league anymore. Each of my clones contains my distinct energy signature. You'll never be able to tell which one is real! Heh, catch me if you can!"

And without a further word, the multitudes blasted off in every direction, fleeing through the air, just above the cloudline, some even descending down into Hell itself.

"Fuck!" Vegeta said aloud, feeling the curse quite deserved. But there wasn't a moment to lose. "You'd better hurry and make up your damn mind about what to do with him, Yemma!" he yelled at the ogre, raising into the air with energy charged in his hands.

"Galick Blaze!"

Without a second's hesitation, he began hurling energy blasts in every direction. His eyes could only take in so much, but he did his best to narrow his field of vision to sections at a time. Most of the Cells fled, while others used misdirection attacks, causing the prince's blasts to detonate before reaching their intended targets. Standing mouth agape, King Yemma could only watch on in horror as his beloved check-in station was pounded with Vegeta's rapid energy valley.

"What are you doing, Vegeta!? I swear you'll go to Hell for this!" he roared.

But the relentless Saiyan continued, striking husk after husk of empty energy. Whenever his attacks made contact, Cell's body would dissolve into nothing. This couldn't have been just the multi form technique, it was some kind of combination with multiform and the perfect afterimage. Vegeta fumed as each of his attacks exploded without striking the true Cell.

...

"—Ah, Goku, you're alright. We sure could use your help in tracking down that monster. He's split himself into a thousand copies and run off."
