Guess what? I'm making a crossover story called: SAMURAI JACK MEETS THE POWERPUFF GIRLS! It's almost finished and I'm making the most anticipated dark story called: "DEATH OF THE POWERPUFF GIRLS(TM)" It's coming soon this Summer. Cannot wait for it. GREAT JOB!
Towards the end of the episode, Professor Utonium goes into a secret room under his lab. At the bottom of a lengthy spiral staircase, a long ornate box rests under a layer of dust.
Wiping it away, the professor pulls a small, unassuming key out of his labcoat's pocket. He proceeds to open it, the lid creaking as it's raised. Slowly Utonium reaches for the gift passed down to him through several generations.
He brings the sword upstairs, into his lab. Countless tests and experiments are performed. The item is imbued with impossibly strong positive charges. It's risky, but worth a shot...it may be just the thing he needs.
He grinds the metal of the blade into a powder, and combines it with a special absorbent liquid.
And at last, he has finally discovered true, permanent Antidote X. Antidote X that could destroy his girls. Antidote X that...if used properly, could vaporize this new threat to Townsville.
The last of true, permanent Chemical X had been used in the blast that created his daughters...every other ounce of it he made was a weaker version, a copy, nowhere near as powerful as the original. Where had he found such a potent substance? An old excavation site in Japan...said to be the resting place of an ancient evil.
Try as they might they would never end up defeating Aku since it is as the Legend says, only a relic of righteous might like Jack's sword can pierce through Aku's near-invincible defense and that still holds true, tragic but true so yeah, defeat for PPG, not for Aku. XD lol
No, they cannot harm him since as Aku said "No mere mortal can harm the great Aku" and that was for a reason, only something like Jack's magical sword can pierce Aku's defenses and the PPG only have might and energy-supported weapons, yet no relic that can pierce the defenses of Aku as Jack's Sword can however.
