Creates two blades far harder than steel that are immune to magic that's very effective against evil

Two terrible black-green blades, materialized on the forearms of Cell, the devil himself, had ripped the enchanted blade from the Saiyan's hands, snapping it in two.

There he stood, walking upon air, grinning like the demon he was: Cell, completely whole, completely full of evil.

"Fooled you."

"I'm sure you're also wondering about the fate of your precious sword," said Cell. "It had proven a nuisance on quite a few occasions before, if you'll recall. Why, you and your father nearly even managed to destroy me with it! Oh, how far we've all come since then," the creature chuckled. "But you should have known better than to use it against me twice. I have Goku's cells after all—the same techniques won't work on me over and over. To protect myself, I used magic materialization before the tournament to produce these two blades. Despite being far harder than any steel, they contain none of my own energy whatsoever; as a result, your sword's magical properties could do nothing against them." As he spoke, he clenched his fists. The two blades detached from his forearms and spun on telekinetic threads around behind his back. "They were safely hidden away under my wings for the duration of the fight."

"That sword is magical, right?"

Trunks nodded. "Yeah, it really is something. It was a gift from a friend. The blade can destroy pretty much anything that's evil or wicked in some way."
